As we reach the official end of hurricane season, 2020 will be one for the record books. Looking back at these long, surprising, sometimes downright crazy past six months (seven if you count when the first named storms actually started forming), there are many noteworthy statistics and patterns that drive home the significance of this hurricane season, and the ways climate change may have contributed to it.

<p>Hurricane activity this year <a href="https://twitter.com/philklotzbach/status/1329930734635630593" target="_blank">broke some records</a>. As of today, we have had a record 30 named storms, of which 13 turned into hurricanes. The first two, Arthur and Bertha, even formed before June 1, the official start of hurricane season. The third formed on June 1 itself.</p><p>This is also only the second time in tropical storm naming history, the first time being in 2005, that the National Hurricane Center <a href="https://www.nhc.noaa.gov/aboutnames.shtml" target="_blank">had to use the Greek alphabet letters</a> to name storms after the regular list of names was exhausted. As the season progressed, storms generally got stronger – the image below gives a good idea of this progression. While a pattern like this is not unseen, it certainly is not usually this striking (for instance, see timelines of <a href="https://en.wikipedia.org/wiki/Timeline_of_the_2005_Atlantic_hurricane_season" target="_blank" rel="noopener noreferrer">2005</a>, <a href="https://en.wikipedia.org/wiki/Timeline_of_the_2017_Atlantic_hurricane_season" target="_blank" rel="noopener noreferrer">2017</a>, <a href="https://en.wikipedia.org/wiki/Timeline_of_the_2018_Atlantic_hurricane_season" target="_blank" rel="noopener noreferrer">2018</a>, and <a href="https://en.wikipedia.org/wiki/Timeline_of_the_2019_Atlantic_hurricane_season" target="_blank" rel="noopener noreferrer">2019</a>).</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDg0NzU2MS9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY0OTAyMDY3Nn0.BhJhN_ErgAy_w5VzMcYKPf9KHfLF6NvhQqJS8cj3HEY/img.png?width=980" id="e8972" class="rm-shortcode" data-rm-shortcode-id="ea63282304cdf72c8bf095c11469abf9" data-rm-shortcode-name="rebelmouse-image" />
<p>Fortunately, the high level of activity did not translate into a higher number of major hurricanes this season. The August <a href="https://www.noaa.gov/media-release/extremely-active-hurricane-season-possible-for-atlantic-basin" target="_blank">updated forecast</a> from the National Oceanic and Atmospheric Administration (NOAA) had called for 19-25 named storms, with 7-11 turning into hurricanes, 3-6 of which would be major (Category 3 or higher). The total number of named storms and hurricanes went up, but the latter prediction did not change from the <a href="https://www.noaa.gov/media-release/busy-atlantic-hurricane-season-predicted-for-2020" target="_blank">original forecast released in May</a> (see infographics below).</p><p>So, even though 2020 surpassed the predicted number of named storms and hurricanes, as of today, six of the 13 hurricanes were major, still (barely) within the prediction. Of all the named storms, 12 made landfall in the U.S., six as hurricanes. As of today, the season was record-setting for named storms. It ranks <a href="https://twitter.com/philklotzbach/status/1329930734635630593" target="_blank">second</a> for hurricanes & major hurricanes.</p>

<p>Both Gulf and East Coast states were affected by landfalling hurricanes, and, strikingly, very <a href="https://www.washingtonpost.com/weather/2020/11/16/tropical-storm-winds-lower-48/" target="_blank" rel="noopener noreferrer">few coastal counties have not been affected</a> by tropical storm winds this season. Many of the 2020 storms formed in the Caribbean or Gulf of Mexico, hence nine out of the 12 U.S. landfalling storms targeting the Gulf states. Louisiana, for example, suffered five landfalls starting in May with TS Bertha.</p><p>This is the 6th year in a row that named storms formed before the official start of the season, and the 5th season in a row with at least one category 5 hurricane. It was also the first year to have two major hurricanes in the month of November (Eta and Iota, a Category 4 and 5 respectively), and September 2020 alone had 10 storms – almost equal to the number of total storms for the entirety of an average season, which is currently 12.</p><p>The 2020 season also had 27 named storms that hold the <a href="https://en.wikipedia.org/wiki/List_of_Atlantic_hurricane_records" target="_blank">record for earliest formation by initial letter</a> – most of the previous records were set in 2005.</p>
<h3>A Bit of Science</h3><p>One characteristic of the 2020 season that will be discussed for quite a while is the <a href="https://www.nhc.noaa.gov/aboutgloss.shtml#r" target="_blank" rel="noopener noreferrer">rapid intensification</a> of storms. <a href="https://weather.com/storms/hurricane/news/2020-11-15-atlantic-hurricane-season-ten-storms-rapidly-intensify" target="_blank" rel="noopener noreferrer">Ten storms</a> so far this year have seen sustained winds gain 35 mph or more in speed within 24 hours or less, with Eta and Iota beating all records with 80 mph increases as they neared landfall on the coast of Nicaragua. The <a href="https://weather.com/storms/hurricane/news/2020-11-15-atlantic-hurricane-season-ten-storms-rapidly-intensify" target="_blank" rel="noopener noreferrer">1995 season also had 10 rapidly intensifying storms</a> – but not at the same rate. Some scientists <a href="https://journals.ametsoc.org/bams/article/98/3/495/70036/Will-Global-Warming-Make-Hurricane-Forecasting" target="_blank" rel="noopener noreferrer">argue</a> that rapid intensification is likely to become a more common feature of future storms, making forecasting trickier. <a href="https://www.nature.com/articles/s41467-019-08471-z.pdf" target="_blank" rel="noopener noreferrer">Research has shown</a> that rapid intensification, observed over the past 40 years, has become more frequent, a pattern that is not supported by models of internal climate variation alone, suggesting that human-caused global warming might be a factor. <a href="https://journals.ametsoc.org/jcli/article/31/20/8281/92614/Projected-Response-of-Tropical-Cyclone-Intensity" target="_blank" rel="noopener noreferrer">Another study</a> determined that the chance of a hurricane intensifying went from 1 in 100 in the early 80s to 1 in 20 by mid-2005.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDg0NzU2OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMjI2NjM3MX0.753Urx0au33Hqz3vy1bTqOWf4rZLyp3JPPGCF-nZ4Co/img.jpg?width=980" id="3d54a" class="rm-shortcode" data-rm-shortcode-id="021f4862a8df4f5a055d450e7a7b0522" data-rm-shortcode-name="rebelmouse-image" />
<p>What we are seeing in the U.S. is also being seen across the globe. Rapidly intensifying <a href="https://www.washingtonpost.com/weather/2019/10/07/tropical-storm-category-hours-super-typhoon-hagibis-intensifies-one-fastest-rates-record/" target="_blank" rel="noopener noreferrer">typhoons</a> have wreaked havoc in Asia this year, and we saw storms crossing the Caribbean and hitting Central American countries as major hurricanes formed in less than 24 hours. Nicaragua was hit by two category 4 hurricanes in two weeks, <a href="https://www.washingtonpost.com/weather/2020/11/17/nicaragua-eta-iota-landfalls/" target="_blank" rel="noopener noreferrer">something never seen before</a>.</p><p>I have <a href="https://blog.ucsusa.org/astrid-caldas/dangerous-hurricane-season-to-open-amidst-covid-19" target="_blank" rel="noopener noreferrer">previously written</a> that hurricanes are becoming <a href="https://rd.springer.com/article/10.1007/s00382-013-1713-0" target="_blank" rel="noopener noreferrer">stronger</a>, <a href="https://www.nature.com/articles/s41586-018-0673-2" target="_blank" rel="noopener noreferrer">wetter</a>, <a href="https://www.nature.com/articles/s41612-019-0074-8" target="_blank" rel="noopener noreferrer">slower</a>, and <a href="https://www.pnas.org/content/116/48/23942" target="_blank" rel="noopener noreferrer">more destructive</a>, and all these trends have been <a href="https://www.nytimes.com/2020/11/10/climate/climate-change-hurricanes.html" target="_blank" rel="noopener noreferrer">linked to anthropogenic global warming</a> in one way or another. <a href="https://www.ncei.noaa.gov/news/link-between-heat-and-hurricanes" target="_blank" rel="noopener noreferrer">New studies</a> since have also pointed to the fact that the link between heat and the intensity of tropical cyclones is becoming clearer, and that their <a href="https://www.pnas.org/content/117/22/11975" target="_blank" rel="noopener noreferrer">intensity over the past four decades</a> has increased.</p><p>Another new characteristic of Atlantic hurricanes determined in a study is that they are losing strength more slowly. Whereas in the 60's hurricanes lost 75 percent of their strength within 24 hours of making landfall, today they lose only 50 percent in the same amount of time. That certainly contributes to a higher impact from rainfall and winds.</p><p>The very active forecast released in August by NOAA was based on some variables that historically affect Atlantic tropical cyclone activity. In addition to the <a href="https://climatereanalyzer.org/wx/DailySummary/#sst" target="_blank" rel="noopener noreferrer">abnormally warm sea surface temperatures</a>, which act as a type of "fuel" to the formation of storms, there were other factors at play.</p><p>The establishment of a <a href="https://oceanservice.noaa.gov/facts/ninonina.html" target="_blank" rel="noopener noreferrer">La Niña</a> pattern, which historically affects high winds in the Atlantic, tends to diminish the vertical wind shear that could help prevent the formation of a tropical cyclone. Also, according to <a href="https://www.noaa.gov/media-release/extremely-active-hurricane-season-possible-for-atlantic-basin" target="_blank" rel="noopener noreferrer">NOAA</a>, a large-scale climate pattern called the <a href="https://climatedataguide.ucar.edu/climate-data/atlantic-multi-decadal-oscillation-amo" target="_blank" rel="noopener noreferrer">Atlantic Multi-Decadal Oscillation</a> has also been favoring more active hurricane seasons since 1995 by making wind conditions in the tropics more conducive to tropical cyclone formation. This favors weaker tropical Atlantic trade winds and an enhanced west African monsoon, which also affect Atlantic tropical cyclone formation.</p>
<h3>Costs and Future of Hurricanes</h3><p>Tropical cyclones are the <a href="https://www.ncei.noaa.gov/news/calculating-cost-weather-and-climate-disasters" target="_blank" rel="noopener noreferrer">costliest of weather and climate disasters</a>, no doubt due to their widespread impacts: storm surge, wind, rain, all come together to create compound risks in the areas affected. In addition, <a href="https://www.nytimes.com/2018/10/26/nyregion/rebuild-home-hurricane.html" target="_blank" rel="noopener noreferrer">hurricane recovery</a> – ecological, structural, economic – tends to last for years, and <a href="https://cen.acs.org/environment/pollution/Looking-lingering-health-effects-Hurricane/96/i37" target="_blank" rel="noopener noreferrer">health impacts</a> add to the costs.</p><p>The trend in rapid intensification, especially as a storm approaches landfall, can make preparations and evacuations more difficult, if not impossible, and is bound to increase the danger to people and the costs of these disasters. Plus, we cannot forget that storms are more consistently forming before and after the official hurricane season, and that extension can signify a longer period of disaster recovery, as well as a longer period during which communities will have to stay in a state of preparedness.</p><p>Especially costly and worrisome from the point of view of preparedness and recovery is when storms hit the same area successively. Hurricane Laura hit the Louisiana Lake Charles area in August as a Category 4, one of the strongest storms to hit the state. Then Hurricane Delta hit the same general area only six weeks later, while many houses still <a href="https://www.npr.org/2020/10/10/922637167/hundreds-of-thousands-without-power-after-hurricane-delta-sweeps-through-south" target="_blank" rel="noopener noreferrer">had tarps covering their roofs</a>, and people in the region, especially low-income segments of the population, <a href="https://www.npr.org/2020/10/10/922637167/hundreds-of-thousands-without-power-after-hurricane-delta-sweeps-through-south" target="_blank" rel="noopener noreferrer">were far from recovered</a>.</p><p>Last but certainly not least, we are dealing with a pandemic that added to the <a href="https://blog.ucsusa.org/kristy-dahl/as-hurricane-laura-bears-down-on-gulf-coast-data-shows-how-covid-19-may-affect-evacuations" target="_blank" rel="noopener noreferrer">challenges of evacuations, sheltering, and recovery</a>. Because of the unprecedented confluence of hurricane season and the pandemic, many emergency preparedness officials <a href="https://blog.ucsusa.org/astrid-caldas/real-time-lessons-on-covid-19-and-us-hurricane-response-what-weve-learned-from-hanna-and-isaias" target="_blank" rel="noopener noreferrer">learned on the fly</a> how to best accommodate evacuees while trying to contain spread of the novel coronavirus.</p><p>The economic crisis from the pandemic is also leading to a lack of resources for both the people and the authorities to deal effectively with the disaster and take suitable action, something that could take years to resolve. The pandemic is of course a concern around the world, and everywhere people are scrambling to deal with these compound risks.</p>
<h3>The Need for Action</h3><p>There is an urgent need for policies and funding for equitable pre-disaster preparedness to help curtail post-disaster costs and recovery. Resources and technical assistance also must be allocated equitably so that those most in need and with the least capability of rebounding have the means to do so.</p><p>We know that human-induced global warming is making storms worse and bringing more destruction with them. We also know we have a path to reduce the carbon emissions that are driving our temperatures up. It is imperative that countries – including the U.S. – continue to increase the ambition of their pledges to reduce global warming emissions and cap warming to well below 2 degrees Celsius, as promised in the Paris Agreement. Only by keeping the worst of climate change at bay will we also limit the wrath of hurricanes, saving lives, property, and resources.</p><p>But for now, any way you look at it, the unprecedented 2020 season is one for the history books.</p>

Will concern over the climate crisis stop people from having children?
<p>A first-of-its-kind academic study suggests that it already has. The study, published in the journal <a href="https://link.springer.com/article/10.1007/s10584-020-02923-y" target="_blank">Climate Change</a> this month, found that 96.5 percent of respondents were "very" or "extremely concerned" about what the lives of their current or hypothetical children would look like in a future they see as overwhelmingly bleak.</p><p>"[C]limate change is the sole factor for me in deciding not to have biological children," a 31-year-old study participant from Washington said. "I don't want to birth children into a dying world. I dearly want to be a mother, but climate change is accelerating so quickly, and creating such horror already, that bringing a child into this mess is something I can't do."</p><p>The question of whether it is right or desirable to have children in the context of the climate crisis has been <a href="https://www.ecowatch.com/overpopulation-children-climate-crisis-2648533200.html">raised</a> in recent years. New York Representative and Green New Deal champion Alexandria Ocasio-Cortez said in 2019 that it was legitimate to ask whether it was "OK to still have children" given scientific predictions for what the world could look like if industrial societies do not rapidly reduce greenhouse gas emissions. </p><p>A 2018 poll found that 11 percent of 20-to-45 year olds in the U.S. who either did not want children or were unsure about having them cited being "worried about climate change" as one reason. Another 2020 poll found that 14.3 percent of 18-to-44 year olds in the U.S. without children cited climate change as a "major reason" and a further 20.7 percent cited it as a "minor reason."</p>
<p>"This suggests that approximately 12.5 million Americans of what is traditionally considered childbearing age were not having children at least partially because of their climate concerns," the study authors wrote.</p><p>However, the new research is the first time an academic, peer-reviewed study has examined how the climate crisis is influencing reproductive choice. Most academic research has focused on the ethics of having children in countries with large environmental footprints. One <a href="https://today.oregonstate.edu/archives/2009/jul/family-planning-major-environmental-emphasis" target="_blank">2009 study</a> found that having one less child as a U.S. resident was 20 times more effective at reducing one's carbon footprint than other lifestyle choices such as driving more fuel-efficient cars.</p><p>Ethical concerns did partly motivate the study respondents. When asked, "How concerned were/are you about your (potential) child's lifetime carbon footprint?" 59.8 percent of respondents said they were "very" or "extremely concerned."</p>
<p>"I really didn't think a lot about the carbon footprint of having another child, until I read something saying that the best thing you can do to reduce your carbon footprint is not reproduce," a 38-year-old teacher and mother from Minnesota said in the study. "Thinking about that has influenced my decision not to have a third child."</p><p>However, respondents were more concerned with their hypothetical or actual children's futures than the environmental impact of reproducing.</p><p>"The fears about the carbon footprint of having kids tended to be abstract and dry," study leader Matthew Schneider-Mayerson of Yale-NUS College in Singapore told <a href="https://www.theguardian.com/environment/2020/nov/27/climate-apocalypse-fears-stopping-people-having-children-study" target="_blank">The Guardian</a>. "But the fears about the lives of existing or potential children were really deep and emotional. It was often heartbreaking to pore through the responses — a lot of people really poured their hearts out."</p>
<p>Six percent of respondents even admitted to feeling regret for having children. "I was surprised," Schneider-Mayerson told The Guardian. "For parents, this is an extremely difficult statement to make."</p><p>Schneider-Mayerson noted that more research is needed using a wider and more diverse group of respondents. This particular study questioned 607 U.S. adults aged 27 to 45, and they tended to be white, liberal and living in urban areas, Schneider-Mayerson told The Guardian.</p><p>The study respondents were also motivated by an overwhelmingly negative view of the future. Of the 400 who offered their opinions, 92.3 percent predicted a negative future, 5.6 percent thought it would be mixed and only 0.6 percent were positive.</p>
<p>But some climate scientists have argued that having children despite these concerns can bring hope.</p><p>"Personally, I can't advocate for people not to have children in order to fix climate change because why am I fixing climate change? I'm doing it because of my child and because of everybody else's children," atmospheric scientist and Texas Tech University political science professor Katharine Hayhoe told the Canadian Press in 2019, <a href="https://globalnews.ca/news/7490799/climate-change-apocalypse-study/" target="_blank">Global News reported</a>. "So that's what gives us hope."</p><p>Ultimately, Schneider-Mayerson saw the data as another reason to act on climate. "To address this, we really need to act immediately to address the root cause, which is climate change itself," he said.</p>

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.
<p>Here you can learn about the importance of organic hemp oil, why it's better for the environment, and which CBD companies actually make trustworthy products with sustainable farming processes. origins which weigh heavily on many consumers who want to buy a product that's produced in the best way possible for not only themselves to ingest, but for the environment as well through sustainable farming methods. </p><h2>What Is CBD Oil?</h2><p>First things first, CBD stands for cannabidiol, and it's a cannabinoid found within cannabis sativa plants. This plant compound is believed to have many potential benefits, and it is primarily derived from hemp plants via a CO2 extraction process. </p><p>Since CBD is extracted from industrial hemp, which contains only trace amounts of THC (the psychoactive component in cannabis plants), this means that CBD won't make you feel high like marijuana, which has much higher levels of THC that causes psychoactive effects. Instead, the effects of CBD are much more subtle and promote a general sense of calm and relaxation in most users.</p><h2>What Makes a CBD Oil Organic?</h2><p>In terms of organic labels, perhaps the most important (and prominent) certification comes from the United States Department of Agriculture (USDA). This government organization has been labeling foods as "organic" for many years, but what exactly does this certification entail? Essentially, a label indicating that a product is "USDA Organic" or "Certified Organic" means that at least 95% of the ingredients are obtained from organic sources.</p><p>For a crop to be considered organic by the USDA, it must be grown without the use of industrial solvents, irradiation, genetic engineering (GMOs), synthetic pesticides, or chemical fertilizer. Instead, farmers rely on natural substances and <a href="https://www.usda.gov/media/blog/2012/03/22/organic-101-what-usda-organic-label-means" rel="noopener noreferrer" target="_blank">mechanical, physical, or biologically based farming</a> techniques to cultivate healthy and organic crops.</p><p>Before the passage of the 2018 Farm Bill, no hemp-derived products could be dubbed as "certified organic" since the hemp plant and its extracts were still categorized as a Schedule I Controlled Substance. However, it's still difficult for CBD companies to obtain a USDA certified organic label for their products due to the legal grey area that still surrounds CBD extracts. </p><p>Because of these challenges, and due to the fact that industrial hemp has only recently become an agricultural crop, very few CBD oils are USDA certified organic. Rather, many CBD products contain hemp extracts from plants that were grown in organic conditions but may not be federally certified.</p><h2>What are the Best Organic CBD Oil Brands?</h2><p><em>Each product featured here has been independently selected. If you make a purchase using the links included, we may earn commission.</em></p>
<h2>Why Organic Hemp Oil Matters</h2><p>Hemp is a unique plant, not only for its rich cannabinoid content, but also for its ability to absorb a wide variety of components in soil. But this trait poses great risks when it comes to the creation of CBD products derived from hemp.</p><p>Because hemp has a high capacity for compound uptake, this means that the plants can retain <a href="https://www.remedyreview.com/industry/lab-test-results/" target="_blank">harmful chemicals like pesticides</a>, heavy metals, and other residual solvents. This is especially true when it comes to synthetic chemicals that are more toxic to humans, and difficult to remove once they have been absorbed by the hemp plant.</p><p>Organic farming practices help reduce the risk of hemp crops absorbing harsh chemicals that may later end up in CBD oil after extraction. When you're taking CBD as a wellness supplement to help alleviate your symptoms or improve your overall well-being, the last thing you want is to ingest compounds that might negatively outweigh the benefits of CBD. This is an important reason to look for third party lab test results when shopping for CBD products since these certificates of analysis can show the full cannabinoid and terpene profile of a hemp extract, as well as test results that search for the presence of any residual solvents.</p><p>In addition to creating a better end product, organic farming practices are also better for the environment. Sustainable and organic farming methods may <a href="https://www.helpguide.org/articles/healthy-eating/organic-foods.htm" rel="noopener noreferrer" target="_blank">reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy</a>. The use of natural pest deterrents as opposed to chemical pesticides is also better for nearby animal populations and ecosystems.</p><h3>Organic vs. Natural</h3><p>While there are only a select few companies offering certified organic ingredients in their products, almost every brand in the CBD market creates "natural" products. The term "all-natural" or "plant-based" does not mean that a product is organic, and since hemp oil is a natural derivative of hemp plants, these products are often referred to as all-natural. However, there are some synthetic CBD oils that should be avoided because they are chemically constructed and may produce unwanted side effects that are not caused by naturally derived CBD extracts.</p><h2>What are the Benefits of Organic CBD Oil?</h2><p>There's a long list of potential CBD oil health benefits, and some of the most common wellness advantages include:</p><ul class="ee-ul"><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2503660/" target="_blank">Chronic pain relief</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4604171/" target="_blank">Anti-anxiety effects</a></li><li>Better sleep</li><li><a href="https://www.psychologytoday.com/us/blog/inner-source/201901/cbd-oil-mental-health-should-you-take-it-too" rel="noopener noreferrer" target="_blank">Improvements in mood</a></li><li>Internal balance and regulation</li></ul><p>When dealing with pain, inflammation, sleep issues, and mental health struggles, it can be hard to find sufficient treatment options. The use of certain prescriptions can cause unwanted side effects, yet they are often the only solution for patients with these medical conditions. In search of other therapies, people have started to flock towards CBD oil as an alternative remedy for a variety of conditions. However, it should be noted that CBD products are not approved by the Food and Drug Administration (FDA), and you should seek your doctor's advice before using CBD if you have a serious medical condition.</p><h2>Look at the Labels Before You Buy CBD Oil</h2><p>When you go online to buy CBD oil, you'll quickly realize there is an overwhelming number of brands that are saturating the market. It can be difficult to determine which products are truly as good as they make themselves out to be. Always look for up-to-date third-party lab tests so you know you are getting a great product, and don't hesitate to contact the brand if you have any additional questions. And if you're intent on purchasing 100% organic CBD oil, it's best to look for certified products or brands that are held to strict regulatory standards.</p><p><strong>Melena Gurganus </strong>is the Reviews Editor at EcoWatch.

Scientific integrity is key for protecting the field against attacks. sanjeri / Getty Images
By Maria Caffrey
As we approach the holidays I, like most people, have been reflecting on everything 2020 has given us (or taken away) while starting to look ahead to 2021.
<p>One thing I am particularly looking forward to is hearing more from experts and scientists so that we can usher in a new era of science-based policymaking. But before we get too excited about what those changes could be, there are some essential actions that the Biden administration must take to ensure that the scientists and their work will be protected over the next four years and beyond.</p><p>I am eager to put the past behind me, but I am also acutely aware that if we do not make the effort to learn from our history then we risk repeating it. So how can we close the gaps in our laws to ensure that industry cannot profit at the expense of public health or diminish our public lands? Two words: scientific integrity.</p><p>Scientific integrity refers to the professional culture, norms, and rules that underpin the production, communication, and use of scientific research. Now more than ever we need to establish scientific integrity policies and laws that prevent the suppression and distortion of scientific research, and prohibit retaliations against scientists. Without this we risk future abuse and manipulation of science and harm to the public good.</p>
We Need More Than Listening
<p>By now we have all become sadly accustomed to the current administration sidelining scientists, most prominently Dr. Anthony Fauci, because the facts they provide do not fit with the political rhetoric of the moment.</p><p>I have <a href="https://www.csldf.org/2019/08/22/csldf-helps-climate-scientist-maria-caffrey-fight-for-scientific-integrity/" target="_blank">my own history</a> of filing a scientific integrity complaint with the National Park Service (which falls under the Department of the Interior) after senior ranking employees attempted to censor one of my scientific reports. I know all too well the damage and pain that these actions cause, not just for the individual scientist, but also because these <a href="https://www.ucsusa.org/resources/attacks-on-science" target="_blank" rel="noopener noreferrer">attacks on science</a> over the last few years have undermined sound, evidence-based decision making.</p><p>President-elect Biden has repeatedly said that he will <a href="https://thehill.com/homenews/521638-trump-biden-will-listen-to-the-scientists-if-elected" target="_blank" rel="noopener noreferrer">listen to the scientists</a>. While this is certainly a welcome change, listening can only take us so far. This past week Lauren Kurtz from the <a href="https://www.csldf.org/" target="_blank" rel="noopener noreferrer">Climate Science Legal Defense Fund</a> and my colleague <a href="https://www.ucsusa.org/about/people/gretchen-goldman" target="_blank" rel="noopener noreferrer">Gretchen Goldman</a> published <a href="https://www.scientificamerican.com/article/ten-steps-that-can-restore-scientific-integrity-in-government/" target="_blank" rel="noopener noreferrer">an article</a> listing 10 actions the new administration should implement to show their commitment to strengthening government science:</p><ol><li>Clearly prohibit political interference and censorship.</li><li>Protect scientists' communication rights.</li><li>Acknowledge that attempts to violate scientific integrity, even if ultimately not fruitful, are still violations.</li><li>Protect federal scientists' right to provide information to Congress and other lawmakers.</li><li>Commit to incorporating the best science as part of agency decisions.</li><li>Elevate agency scientific integrity policies to have the full force of law.</li><li>Publicly release anonymized information about scientific integrity complaints and their resolutions at every agency.</li><li>Institute an intra-agency workforce, potentially under the White House <a href="https://www.ucsusa.org/sites/default/files/2020-09/strengthening-science-and-si-at-ostp.pdf" target="_blank" rel="noopener noreferrer">Office of Science and Technology Policy</a>, to coordinate scientific integrity efforts across agencies, foster discussion of policy improvements, and standardize criteria for policies across agencies.</li><li>Strengthen whistleblower protections.</li><li>Ensure that policies cover all actors who will be dealing with science.</li></ol><p>All of these recommendations have been reinforced by what we have learned during the Trump administration. They would ensure that no future administration could do things like <a href="https://www.ucsusa.org/resources/attacks-on-science/official-modified-reports-increase-doubt-climate-science" target="_blank">edit climate change reports</a> to include <a href="https://blog.ucsusa.org/maria-caffrey/science-denied-again-interior-department-adds-inaccurate-climate-change-info-to-reports" target="_blank">scientifically unsound language</a> questioning climate change, <a href="https://www.ucsusa.org/resources/attacks-on-science/doi-officials-suppress-oil-rig-safety-concerns" target="_blank">suppress oil</a> and <a href="https://www.ucsusa.org/resources/attacks-on-science/trump-administration-hides-oil-exploration-harms-polar-bears" target="_blank">gas safety</a> <a href="https://www.ucsusa.org/resources/attacks-on-science/scientists-concerns-oil-and-gas-operations-alaska-buried-trump" target="_blank">information</a>, <a href="https://www.ucsusa.org/resources/attacks-on-science/doi-restricts-scientists-attending-scientific-conferences" target="_blank">prevent scientists from discussing their work</a> in <a href="https://www.ucsusa.org/resources/attacks-on-science/communication-multiple-agencies-restricted-after-trump-takes-office" target="_blank">public forums</a>, or <a href="https://www.ucsusa.org/resources/attacks-on-science/doi-officials-bury-report-showing-hundreds-endangered-species-are" target="_blank">withhold vital</a> <a href="https://www.ucsusa.org/resources/attacks-on-science/endangered-species-threatened-arizona-due-politics-and-bad-science" target="_blank">scientific</a> <a href="https://www.ucsusa.org/resources/attacks-on-science/scientists-ignored-california-dam-project" target="_blank">information</a> that is required under other laws, such as the <a href="https://www.ucsusa.org/resources/attacks-on-science/doi-dismantled-endangered-species-act" target="_blank">Endangered Species Act</a>.</p><p>When it comes to changes at the Department of the Interior, the Union of Concerned Scientists has articulated <a href="https://www.ucsusa.org/sites/default/files/2020-08/doi-fact-sheet-roadmap-for-science.pdf" target="_blank">specific actions</a> that the Biden administration should implement if they want to ensure that government scientists are free to do their work without political interference. Scientists deserve the right of last review and the ability to comment publicly, they shouldn't have to fight for their publications to be published, and they should have a pathway to anonymously file a complaint if they think their rights have been breached.</p><p>I spent over a year staring at my finished climate change report on my National Park Service desk wondering why it was being delayed. I was later pressured to makes edits I did not agree with. When I fought back I was told that I could be removed as an author or have my work not published at all. Given my own experience, these suggestions to fix our current system are deeply personal to me because I have seen how Interior can work against scientists to silence them when their work is politically inconvenient.</p>
Time for Action
<p>I have spoken to many scientists, particularly federal scientists, who are eager to turn the page so they can hurry back to the work they had been doing before this administration, but I urge caution in assuming that things can be "normal" again.</p><p>Before Trump, I naively thought the scientific integrity policies established during the <a href="https://obamawhitehouse.archives.gov/blog/2016/12/19/scientific-integrity-policies-update" target="_blank">Obama administration</a> would be sufficient. I never imagined that any administration could so willfully ignore and attack expert advice and evidence that is intended to protect us and our public lands.</p><p>I have personally witnessed how hard our federal scientists work. They put in long hours with minimal pay (far less that what they could get if they worked in private industry) to pursue one simple goal: to make things better for the nation.</p><p>We need stronger scientific integrity policies to protect these people and their work. But more than that, we need stronger scientific integrity laws because they also benefit society.</p>

How To Talk To People About the Climate Crisis When Scary Facts Are Not Enough
25 November
Insights + Opinion
Climate change can evoke intense feelings, but a conversational approach can help. Reed Kaestner / Getty Images
Anger, anxiety, overwhelm … climate change can evoke intense feelings.
<p>"It's easy to feel dwarfed in the context of such a global systemic issue," says psychologist Renée Lertzman.<br/></p><p>She says that when people experience these feelings, they often shut down and push information away. So to encourage climate action, she advises not bombarding people with frightening facts.</p>
<iframe style="border: none" src="//html5-player.libsyn.com/embed/episode/id/16550327/height/45/theme/standard/thumbnail/yes/direction/backward/" height="45" width="100%" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe>
<p>"When we lead with information, we are actually unwittingly walking right into a situation that is set up to undermine our efforts," she says.<br></p><p>She says if you want to engage people on the topic, take a compassionate approach. Ask people what they know and want to learn. Then have a conversation.</p><p>This conversational approach may seem at odds with the urgency of the issue, but Lertzman says it can get results faster.</p><p>"When we take a compassion-based approach, we are actively disarming defenses so that people are actually more willing and able to respond and engage quicker," she says. "And we don't have time right now to mess around, and so I do actually come to this topic with a sense of urgency… We do not have time to not take this approach."</p><p><em>Reposted with permission from <a href="https://yaleclimateconnections.org/2020/11/why-frightening-facts-dont-always-move-people-to-action-on-climate-change/" target="_blank">Yale Climate Connections</a>.</em></p>

More than half the bacteria in the human gut microbiome are sensitive to glyphosate, the mostly commonly used herbicide in the world, reported scientists this month in the Journal of Hazardous Materials.
<p>Researchers from the University of Turku in Finland recently developed a novel bioinformatics tool to predict if beneficial bacteria in the human gut are affected by exposure to glyphosate.</p><p>They found that the herbicide could disturb the natural cycles of microbiome life, and potentially harm human health, through weakening the system and causing greater susceptibility to diseases.</p><p>"Glyphosate targets an enzyme ... [that] is crucial to synthesizing three essential amino acids," said Pere Puigbò, who co-developed the bioinformatics tool.</p>
<p>Glyphosate is regularly in the <a href="https://www.ecowatch.com/atrazine-harms-endangered-species-2648937774.html" target="_self">news</a>, viewed as a potential threat to <a href="https://www.theguardian.com/environment/2020/nov/22/war-of-the-weedkiller-why-environmentalists-are-concerned-about-moves-to-ban-roundup" target="_blank">health</a> and <a href="https://www.capitalpress.com/nation_world/epa-backs-arguments-against-25-million-glyphosate-verdict/article_f7ee49e0-194d-11eb-909b-bfe8072212c6.html" target="_blank">well-being</a> because of its widespread use on crops including corn, soy and canola. It is also a household weed killer, particularly the Monsanto/Bayer-owned brand <a href="http://www.ecowatch.com/tag/monsanto">Roundup</a>.</p><p>The herbicide is currently banned from many <a href="https://sustainablepulse.com/2019/05/28/glyphosate-herbicides-now-banned-or-restricted-in-17-countries-worldwide-sustainable-pulse-research/#.X7x66C2ZNE4" target="_blank">countries</a> including Germany, Saudi Arabia and Vietnam, and is heavily restricted in others. <a href="https://www.sfpublicpress.org/as-cancer-concerns-lead-cities-to-ban-herbicide-sf-scales-back-use-of-roundup/" target="_blank" rel="noopener noreferrer">Cities </a>and <a href="https://www.wzzm13.com/article/news/health/bill-would-limit-residential-use-of-glyphosate/69-ffa2b3c1-cf47-477a-ab81-81bbb4615257" target="_blank" rel="noopener noreferrer">states</a> across the U.S. are starting to reduce use or pushing for a ban, due to mounting health concerns. Other cities, such as Los Angeles and Miami, have already banned use.</p><p>"We need experimental research to study the effects of glyphosate on microbial communities in variable environments," said researcher Marjo Helander in a statement about the findings.</p><p>"This groundbreaking study provides tools for further studies to determine the actual impact of glyphosate on human and animal gut microbiota and thus to their health."</p>

Seagrass: Another Vital Carbon-Sequestering Ecosystem Threatened by Climate Change
24 November

By Melissa Gaskill
Two decades ago scientists and volunteers along the Virginia coast started tossing seagrass seeds into barren seaside lagoons. Disease and an intense hurricane had wiped out the plants in the 1930s, and no nearby meadows could serve as a naturally dispersing source of seeds to bring them back.
<p>The seeding effort eventually delivered more than 70 million seeds — and it paid off, creating some 9,000 acres of the underwater plants.</p>

</div></blockquote></div><p>Now monitoring of these restored meadows reveals multiple benefits to their restoration, including substantial increases in fish and invertebrate abundance, improved water clarity, and significant trapping of carbon and nitrogen.</p><p>"Planting adult seagrass is very labor intensive, but we started looking at using seeds in the lab and found it was quite easy," said biologist Robert "JJ" Orth, lead author on a new <a href="https://advances.sciencemag.org/content/6/41/eabc6434" target="_blank">paper</a> about the project. "These areas have good water quality, are shallow and are near the ocean so they get bathed in cooler water — perfect conditions. It was a surprise how quickly it happened."</p>

Restored seagrass beds in Virginia now provide habitat for hundreds of thousands of scallops. Bob Orth, Virginia Institute of Marine Science / CC BY 2.0
<p>The paper is part of a growing trend of evidence suggesting seagrass meadows can be easier to restore than other coastal habitats.</p><p>Successful seagrass-restoration methods include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0304377099000078?via%3Dihub" target="_blank">transplanting shoots</a>, <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1061-2971.2004.00314.x" target="_blank" rel="noopener noreferrer">mechanized planting</a> and, more recently, <a href="https://www.nature.com/articles/s41467-020-17438-4" target="_blank" rel="noopener noreferrer">biodegradable mats</a>. Removing threats, proximity to donor seagrass beds, planting techniques, project size and site selection all play roles in a restoration effort's success.</p><p>Human assistance isn't always necessary, though. In areas where some beds remain, seagrass can even recover on its own when stressors are reduced or removed. For example, seagrass began to recover when Tampa Bay improved its water quality by reducing nitrogen loads from runoff by roughly 90%.</p><p>But more and more, seagrass meadows struggle to hang on.</p><p>The marine flowering plants have declined globally since the 1930s and currently disappear at a rate equivalent to a football field every 30 minutes, according to the <a href="https://www.unep.org/resources/report/out-blue-value-seagrasses-environment-and-people" target="_blank" rel="noopener noreferrer">United Nations Environment Programme</a>. And research published in 2018 found the rate of decline is <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2018GB005941" target="_blank" rel="noopener noreferrer">accelerating</a> in many regions.</p><p>The causes of decline vary and overlap, depending on the region. They include thermal stress from climate change; human activities such as dredging, anchoring and coastal infrastructure; and intentional removal in tourist areas. In addition, increased runoff from land carries sediment that clouds the water, blocking sunlight the plants need for photosynthesis. Runoff can also carry contaminants and nutrients from fertilizer that disrupt habitats and cause algal blooms.</p><p>All that damage comes with a cost.</p>The Value of Seagrass
<p>As with ecosystems like rainforests and <a href="https://therevelator.org/mangroves-climate-change/" target="_blank">mangroves</a>, loss of seagrass increases carbon dioxide emissions. And that spells trouble not just for certain habitats but for the whole planet.</p><p>Although seagrass covers at most 0.2% of the seabed, it <a href="https://www.unenvironment.org/news-and-stories/story/seagrass-secret-weapon-fight-against-global-heating" target="_blank">accounts for 10%</a> of the ocean's capacity to store carbon and soils, and these meadows store carbon dioxide an estimated 30 times faster than most terrestrial forests. Slow decomposition rates in seagrass sediments contribute to their <a href="https://www.researchgate.net/publication/238506081_Assessing_the_capacity_of_seagrass_meadows_for_carbon_burial_Current_limitations_and_future_strategies" target="_blank" rel="noopener noreferrer">high carbon burial rates</a>. In Australia, according to <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15204" target="_blank" rel="noopener noreferrer">research</a> by scientists at Edith Cowan University, loss of seagrass meadows since the 1950s has increased carbon dioxide emissions by an amount equivalent to 5 million cars a year. The United Nations Environment Programme reports that a 29% decline in seagrass in Chesapeake Bay between 1991 and 2006 resulted in an estimated loss of up to 1.8 million tons of carbon.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDgwMzMxOS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0MDk0NDAwOX0.ILZN1S7VzsMsdiF6usSunDgL0wYRlgtFEoLb5Hinwq4/img.jpg?width=980" id="3b37c" class="rm-shortcode" data-rm-shortcode-id="06cc09d311c7b9b0d90ae063f04bbb5b" data-rm-shortcode-name="rebelmouse-image" />

<p>Seagrasses also protect costal habitats. A healthy meadow slows wave energy, reduces erosion and lowers the risk of flooding. In Morro Bay, California, a 90% decline in the seagrass species known as eelgrass caused extensive erosion, according to a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0272771420303528?via%3Dihub" target="_blank" rel="noopener noreferrer">paper</a> from researchers at California Polytechnic State University.</p><p>"Right away, we noticed big patterns in sediment loss or erosion," said lead author Ryan Walter. "Many studies have shown this on individual eelgrass beds, but very few studies looked at it on a systemwide scale."</p><p>In the tropics, seagrass's natural protection can reduce the need for expensive and often-environmentally unfriendly <a href="https://www.nioz.nl/en/news/zeegras-spaart-stranden-en-geld" target="_blank" rel="noopener noreferrer">beach nourishments</a> regularly conducted in tourism areas.</p><p>Seagrass ecosystems improve water quality and clarity, filtering particles out of the water column and preventing resuspension of sediment. This role could be even more important in the future. By producing oxygen through photosynthesis, meadows could help offset decreased oxygen levels caused by warmer water temperatures (oxygen is less soluble in warm than in cold water).</p><p>The meadows also provide vital habitat for a wide variety of marine life, including fish, sea turtles, birds, marine mammals such as manatees, invertebrates and algae. They provide nursery habitat for <a href="https://wedocs.unep.org/bitstream/handle/20.500.11822/32636/seagrass.pdf?sequence=1&isAllowed=y" target="_blank" rel="noopener noreferrer">roughly 20%</a> of the world's largest fisheries — an <a href="https://www.floridamuseum.ufl.edu/science/seagrass-meadows-harbor-wildlife-for-centuries/" target="_blank" rel="noopener noreferrer">estimated 70%</a> of fish habitats in Florida alone.</p><p>Conversely, their disappearance can contribute to die-offs of marine life. The loss of more than 20 square miles of seagrass in Florida's Biscayne Bay may have helped set the stage for a widespread <a href="https://www.wlrn.org/2020-08-14/the-seagrass-died-that-may-have-triggered-a-widespread-fish-kill-in-biscayne-bay" target="_blank">fish kill</a> in summer 2020. Lack of grasses to produce oxygen left the basin more vulnerable when temperatures rose and oxygen levels dropped as a result, says Florida International University professor Piero Gardinali.</p>Damaged Systems, a Changing Climate
<p>Governments and conservationists around the world have already put a lot of effort into coastal restoration efforts. And that's helped some seagrass populations.</p><p>Where stressors remain, though, restoration grows more complicated. <a href="https://www.rug.nl/research/portal/en/publications/the-future-of-seagrass-ecosystem-services-in-a-changing-world(3a8c56db-7bed-4c9e-ac7f-c72453e2a102).html" target="_blank">Research</a> published this September found that only 37% of seagrass restorations have survived.

<p>In Chesapeake Bay a cold-water species of seagrass is currently hitting its heat limit, especially in summer, according to Alexander Challen Hyman of University of Florida's School of Natural Resources and Environment. As waters continue to warm due to climate change, the species likely will disappear there.</p><p>Climate-driven sea-level rise complicates the problem as well. Seagrasses thrive at specific depths — too shallow and they dry out or are eaten, too deep and there isn't enough light for photosynthesis.</p>But There’s Good News, Too
<p>Luckily, left to its own devices, a seagrass meadow can flourish for hundreds of years, according to a <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2019.1861" target="_blank" rel="noopener noreferrer">paper</a> published last year by Hyman and other researchers from the University of Florida. The researchers arrived at their conclusion by looking at shells of living mollusks and fossil shells to estimate the ages of meadows in Florida's Big Bend region on the Gulf Coast.</p><p>That area has extensive, relatively pristine seagrass meadows. "Our motivation was to understand the past history of these systems, and shells store a lot of history," said co-author Michal Kowalewski.</p><p>A high degree of similarity between living and dead shells indicates a stable area, while a mismatch suggests an area shifted from seagrass to barren sand. The researchers found that long-term accumulations of shells resembled living ones, suggesting that the seagrass habitats have been stable over time.</p><p>That stability allows biodiversity to thrive, creating conditions where specialist species can survive and flourish, according to Hyman.</p><p>Discovering the long-term stability of seagrass meadows has implications for choosing restoration sites, Kowalewski notes.</p><p>"There must be reasons they thrive in one place, while a mile away they don't and fossil data says they probably never did," he said. "If we remove a seagrass patch, we cannot hope to plant it somewhere else. It's not just the seagrass that is special. The location at which it's found is special, too."</p><p>A better approach is conserving these habitats in the first place, but we're not doing enough of that right now. The UN reports that marine protected areas safeguard just 26% of recorded seagrass meadows, compared with 40% of coral reefs and 43% of mangroves.</p><div id="0e43d" class="rm-shortcode" data-rm-shortcode-id="5dd416de57a6668bb7b310f46cb45a94"><blockquote class="instagram-media"

Carbon dioxide levels in the atmosphere hit a new record in 2019 and have continued climbing this year, despite lockdowns and other measures to curb the pandemic, the World Meteorological Organization (WMO) said on Monday, citing preliminary data.
<p>Levels of carbon dioxide, a product of burning fossil fuels that <a href="https://www.dw.com/en/are-international-pledges-bold-enough-to-stop-global-warming/a-41343653" target="_blank">contribute to global warming</a>, peaked at 410.5 parts per million in 2019, according to the WMO. The annual increase is larger than the previous year and surpasses the average over the last decade.</p><p>"Such a rate of increase has never been seen in the history of our records," WMO Secretary-General professor Petteri Taalas said, referring to increases since 2015 and urging for a "sustained flattening of the (emissions) curve."</p>
<h2>Lockdown Drops Just a 'Blip'</h2><p>The Geneva-based UN agency noted that shutdowns, border closures, <a href="https://www.dw.com/en/to-fly-or-not-to-fly-the-environmental-cost-of-air-travel/a-42090155" target="_blank" rel="noopener noreferrer">flight groundings</a> and other restrictions had cut emissions of many pollutants and <a href="https://www.dw.com/en/our-addiction-to-growth-is-harming-the-climate/a-41429203" target="_blank" rel="noopener noreferrer">greenhouse gases like carbon dioxide.</a></p><p>As pandemic measures peaked earlier this year, daily CO2 output dropped 17% below last year's mean level, preliminary results of the WMO's main annual Greenhouse Gas Bulletin found.</p><p>But the WMO warned against complacency and said the global plunge in industrial activities due to the pandemic had <a href="https://www.dw.com/en/will-it-soon-be-too-late-to-save-the-climate/a-49889771" target="_blank" rel="noopener noreferrer">not restricted record concentrations of the greenhouse gases</a> that are trapping heat in the atmosphere, increasing temperatures, triggering sea levels to rise and prompting extreme weather.</p><p>"The lockdown-related fall in emissions is just a tiny blip on the long-term graph," WMO chief Petteri Taalas said.</p>
<p>The annual impact was expected to be a drop of between 4.2% and 7.5%. But according to the WMO, this will not cause concentrations of CO2 in the atmosphere to decrease and warned the impact on concentrations was "no bigger than the normal year to year fluctuations."</p><p>Worldwide data is not yet available for 2020 but the trend of surging concentrations appears to be intact, the group said, citing initial readings from its Tasmania and Hawaii stations.</p>

The Argentine black-and-white tegu is an invasive species that can reach four-feet long. Mark Newman / Getty Images
These black-and-white lizards could be the punchline of a joke, except the situation is no laughing matter.
<p>That's because the Argentine black-and-white tegu is an <a href="https://www.ecowatch.com/tag/invasive-species" target="_self">invasive species</a> of dog-sized lizards that scientists worry could pose a threat to <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a> across the Southeast.</p><p>The tegus first came to the region as escaped or released pets and began to spread in South Florida more than a decade ago, <a href="https://www.nationalgeographic.com/animals/2020/11/tegu-lizards-invasive-spreading-southeast-united-states/" target="_blank">National Geographic reported</a>. But they are now reaching other states in the region and have been spotted in Georgia, South Carolina, Texas, Louisiana and Alabama.</p><p>"[T]he entire southeast portion of the United States is at risk," U.S. Geological Survey (USGS) biologist Amy Yackel Adams told National Geographic. "Much of this area has a climate that is suitable for tegus."</p>
<p>For scientists, the tegus' eating habits are the most concerning aspect as they spread. The lizards, which are native to South America and up to four-feet long, consume everything from eggs and small birds to low-growing fruit. In Venezuela, they are nicknamed <em>lobo pollero,</em> or "the chicken wolf," for their habit of stealing eggs from chicken coops. In the U.S., they could pose an additional hazard to the eggs of threatened or endangered species like the Eastern indigo snake.</p><p>Protecting native <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> is a major concern in Georgia, where the tegus have been spotted mostly in Tattnall and Toombs counties, <a href="https://www.discovermagazine.com/planet-earth/giant-tegu-lizards-are-moving-into-georgia-and-theyre-not-welcome" target="_blank">Discover reported</a>.</p><p>"They are very efficient predators of our native fauna that don't recognize them as predators," Georgia Southern University biology professor Lance McBrayer told Discover.</p>
<p>Of special concern are ground-nesting birds such as quails and the gopher tortoise, which is the Georgia state reptile, <a href="https://www.smithsonianmag.com/smart-news/these-four-foot-lizards-will-eat-anything-and-theyre-invading-southeastern-us-180976350/" target="_blank">Smithsonian Magazine reported</a>.</p><p>However, the tegus' egg-stealing ways also make them easier to trap, according to Discover. Seven were captured in Georgia in 2019 and six were captured this year. Those numbers are large enough that McBrayer thinks the lizards are likely breeding in the wild.</p><p>"We suspect that they are breeding, but we have not captured a juvenile," he told Discover. "So, we can't say with absolute certainty that there are baby tegus running around."</p>
<p>McBrayer and Yackel Adams told Discover that the goal is to remove the lizards from Georgia before they can establish a population.</p><p>"We're at that early invasion," Yackel Adams told Discover. "It's the best time to deal with it."</p><p>Meanwhile, state officials are also working to stop the tegus from spreading in South Carolina, where they have been spotted at least nine times since August, <a href="https://abcnews4.com/news/local/eight-more-non-native-black-and-white-tegus-spotted-in-south-carolina" target="_blank">WCIV reported in September</a>.</p>
<p>"The number and distribution of black and white tegu reports in just a few weeks is concerning. Documented sightings come from as far north as Greenville County and as far south as Berkeley County," State Herpetologist Andrew Grosse told WCIV. </p><p>"The individuals removed measured between two and three feet long and consisted of both females and males. Necropsies show the tegus have all been scavenging native plants and animals, including toads, various insects and muscadines. This indicates these individuals are wild, free roaming and foraging opportunistically. It is important that this species does not establish in our state."</p>The climate is a key reason why tegus stand a good chance of spreading throughout the Southeast, since their native region is roughly the same latitude, McBrayer told Discover. Their range could grow even further as the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis<br></a>expands tropical and subtropical conditions to the north, National Geographic reported.

A team of scientists found microplastics in every snow sample taken from Mount Everest. Mariusz Potocki / National Geographic
Apparently, there ain't no mountain high enough to keep away the twin pressures of plastic pollution and the climate crisis.
<p>A series of newly-published studies based on a National Geographic expedition to Mount Everest in 2019 provide a shocking picture of how human activity is impacting the highest point from sea level on Earth. One of the studies even found <a href="https://www.ecowatch.com/tag/microplastics" target="_self">microplastics</a> just below the summit, at 8,440 meters (approximately 27,690 feet).</p><p>"Mt. Everest is somewhere I have always considered remote and pristine," University of Plymouth scientist and National Geographic Explorer Dr. Imogen Napper, who was the lead author on the <a href="https://www.ecowatch.com/tag/plastics" target="_self">plastics</a> study, told EcoWatch in an email. "To know we are polluting near the top of the tallest mountain on earth is a real eye opener – we need to protect and care for our planet."</p>
<h3>Microplastics at the Top of the World</h3><p>Napper's study, published in the journal <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(20)30550-9" rel="noopener noreferrer" target="_blank"><em>One Earth</em></a> Friday, found microplastics in every snow sample taken from Mount Everest. The findings join a growing body of research showing the extent of microplastic pollution in even the most remote corners of the planet.</p><p>"These are the highest microplastics currently ever discovered," Napper told EcoWatch. "Although it sounds exciting, this means that microplastics have been discovered from the depths of the ocean all the way to the highest mountain on earth."</p><p>There has been growing awareness in recent years of the <a href="https://www.ecowatch.com/china-mount-everest-trash-2629508814.html?share_id=4408439" target="_self">buildup of trash</a> on Mount Everest left behind by tourists and climbers. In 2019, the Tibet Autonomous Region Sports Bureau said it removed 9.3 tons of waste, and China closed its Everest base camp to tourists to prevent more pollution. Some media outlets have even begun to refer to the mountain as the "world's highest garbage dump."</p><p>However, Napper's study is the first to focus on the accumulation of microplastics on the mountain specifically. Microplastics are plastics less than five millimeters in length that typically slough off of larger plastics as they degrade. Their small size means they are easily ingested by animals by mistake and are also extremely difficult to clean up.</p>
<p>Napper's team found more microplastics collected near the base camp, where climbers tend to congregate. But they still found five microfibers at the mountain's "balcony," the highest point they studied. Those fibers numbered one clear acrylic fiber, one red polyester fiber and three blue polyester fibers.</p><p>In general, many of the microplastics found on Everest were fibers that could have been brought by climbers.</p><p>"Samples collected on the mountain and in the valley below it revealed significant quantities of polyester, acrylic, nylon, and polypropylene fibres," Napper told EcoWatch. "The materials are increasingly being used to make the high performance outdoor clothing commonly used by climbers, as well as the tents and climbing ropes used in attempts to climb the mountain."</p>
<p>However, other studies have shown that microplastics can be carried to remote environments by the atmosphere. A <a href="https://www.ecowatch.com/plastic-pollution-arctic-snow-ice-2639834233.html" target="_self">2019 study</a> found that plastics were being lifted in the air and deposited as snow in the Arctic and the Alps. Napper said similar mechanisms could be bringing the plastics to Everest.</p><p>"[T]he microplastics may have been transported from lower altitudes by the extreme winds which regularly impact the mountain's higher slopes," Napper said.</p><p>So how can we keep Everest, and other remote environments, plastic free? Napper argued that, while reducing plastic use and improving recycling were both important, it is also crucial to develop new materials. This is particularly the case for the kind of specialized gear used to explore remote areas.</p><p>"There are a lot of promising developments in industry at the moment. We need to keep up the momentum, and ensure that athletic gear is tested and evaluated before use," Napper told EcoWatch. "Solutions need to deliver a positive account, not create future issues."</p>
<h3>Glaciers Melting Into Air</h3><p>Napper's article was just one of at least 16 that came out of the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition. That expedition brought 10 research teams including 34 international and Nepali scientists to Everest from April and June of last year in order to study the impacts of human activity on the mountain.</p><p>In addition to the accumulation of microplastics, studies focused on the impacts of the climate crisis on the mountain. One, <a href="https://www.cell.com/iscience/fulltext/S2589-0042(20)30915-9" rel="noopener noreferrer" target="_blank">published in iScience</a>, detailed how global warming is actually increasing the oxygen available to human climbers as warmer temperatures have increased air pressure. Another, published in <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(20)30549-2" rel="noopener noreferrer" target="_blank">OneEarth</a>, documented how Everest's <a href="https://www.ecowatch.com/tag/glaciers%5D" target="_self">glaciers</a> have thinned by more than 100 meters (approximately 328 feet) since the 1960s. Not only that, but the ice loss is accelerating, and glaciers are losing mass even at high altitudes.</p><p>Study leader and University of St. Andrews glaciologist Dr. Owen King said the melting of the higher glaciers was the "biggest surprise" from the results. His team measured thinning at the 5,700 meter (approximately 18,702 foot) Khumbu icefall and the 6,000 meter (approximately 19,685 foot) Rongbuk and Rongbuk East glaciers.</p><p>"The conditions found at this altitude are usually considered ideal for snow and ice accumulation, but our data suggest that they have now become more susceptible to ice melt," King said in an email to EcoWatch.</p>
<p>The melting of mountain glaciers is a big deal, because they are an important source of water to surrounding communities.</p><p>"Continued and, as we have shown, accelerating ice loss raises concerns about the sustainability of the supply of glacial meltwater, particularly at times of the year when monsoon rainfall cannot provide a backup, or in times of <a href="https://www.ecowatch.com/tag/drought" target="_self">drought</a>," King said.</p><p>Understanding how climate change will impact mountain glaciers is the ultimate goal of the Perpetual Planet expeditions, of which the Everest trip was the first.</p><p>"The 2019 National Geographic and Rolex Perpetual Planet Everest Expedition was selected as a fantastic opportunity to support ground breaking research that fills a critical data gap in our understanding of how mountain systems are changing," Nicole Alexiev, vice president of science and innovation at the National Geographic Society, told EcoWatch in an email. "High mountain glaciers serve as the world's water towers, storing and providing water resources for 1/5 of the global populations. Despite the importance of high mountain systems, there is very little research conducted above 5,000m [approximately 16,404 feet] – especially interdisciplinary research – so we were excited to support this expedition which aimed to examine the world's highest mountain and its glaciers using expertise from the disciplines of biology, geology, glaciology, meteorology, and mapping."</p><p>Future expeditions will explore the Andes and western Canada, where mountain glaciers supply water to Santiago, Chile and the Columbia and Fraser river watersheds.</p>

12 Things You Can Do To Help Stop COVID-19 (in Addition To Staying Home for Thanksgiving)
20 November
Health + Wellness
This Thanksgiving, consider a virtual family gathering. Drazen Zigic / iStock / Getty Images Plus
By Pamela M. Aaltonen
As Americans prepare for the first Thanksgiving in the time of the coronavirus, the Centers for Disease Control and Prevention issued a stark warning a week before the big day: Don't travel.
No over the river and through the woods to grandmother's condo. No flying to a beach gathering with the family you choose.
<p>And if it sounds like the CDC is trying to be like the Grinch who stole Thanksgiving, it is important to remember the grim statistic of <a href="https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html" target="_blank">more than a quarter of a million people dead from COVID-19</a>. There is no mistaking: The coronavirus is out of control.</p><p>Ultimately, lowering the staggering numbers of COVID-19 cases and deaths lies squarely with us. Yes, governments can mandate actions; but we're the ones responsible for adhering to them. Our failure is clear when you look at the latest numbers: Deaths from the virus <a href="https://coronavirus.jhu.edu/" target="_blank">are projected</a> to soon approach 2,000 Americans a day, and <a href="https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html" target="_blank" rel="noopener noreferrer">cases continue to climb</a> in the vast majority of states.</p><p>If national numbers don't spur action, will it help to localize the problem? You can find out what's happening closer to home <a href="https://coronavirus.jhu.edu/data/new-cases-50-states" target="_blank" rel="noopener noreferrer">here</a> at the Johns Hopkins Coronavirus Resource Center. Drill down to see the data in your state and county, then take a moment to pause and consider the catastrophic consequences. It's still within our power to reverse course and lower these numbers. But as a public health <a href="https://www.purdue.edu/hhs/nur/directory/faculty/aaltonen_pamela.html" target="_blank" rel="noopener noreferrer">scholar and researcher</a>, I can tell you that as infections increase, the more difficult that becomes.</p><p>Even the rural states of North Dakota, South Dakota, Iowa and Wyoming <a href="https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html" target="_blank" rel="noopener noreferrer">are experiencing</a> tremendous surges. Exhausted hospitals and health care workers across the U.S. are becoming overwhelmed, if not already there. Overwhelmed systems <a href="https://www.axios.com/coronavirus-surge-hospitals-overwhelmed-b0d089a0-87cc-4745-b128-8b0972c0ddf8.html" target="_blank" rel="noopener noreferrer">place care at risk</a>. Those with other health conditions need medical intervention and hospitalization. And those with a lax attitude about COVID-19 put themselves <a href="https://psnet.ahrq.gov/issue/new-us-health-crisis-looms-patients-without-covid-19-delay-care" target="_blank" rel="noopener noreferrer">at increased risk</a> for negative health outcomes.</p>
<h2>Changing Behavior Is a Must</h2><p>Modifying our behavior minimizes the chances to spread infection. But this is a big task. Government actions <a href="https://www.theatlantic.com/ideas/archive/2020/11/covid-19-is-out-of-control-what-can-we-do/617097/" target="_blank" rel="noopener noreferrer">are most effective</a> when based on local data and the option to loosen or tighten restrictions based on solid information. We should not view these actions as an attempt to take away our civil liberties. Instead, we should think of them as liberating, a way to keep us away from the virus.</p><p>It is not too late to modify your behavior if you've been reluctant to accept the realities of the virus. With promising vaccines on the horizon, our challenge as individuals is to reduce current infection numbers. And to do that, everyone must commit to established public health strategies.</p>
<h2>A Dozen Things You Can Do</h2><ol><li>Always mask up when indoors and around people who don't live in your household.</li><li>Always mask up when outdoors and unable to maintain physical distancing.</li><li>Use either disposable masks or a multi-layer tightly woven cotton mask. Single-layer kerchiefs are insufficient.</li><li>When you mask up, make sure it fits your face and covers both nose and mouth. Wash or sanitize your hands after touching or removing the mask.</li><li><a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/cloth-face-cover-guidance.html" target="_blank" rel="noopener noreferrer">Remember that</a> masks are not a substitute for physical distancing.</li><li>Maintain at least six feet of distance between you and others outside of your household.</li><li>Wash your hands frequently with soap and water for 20 seconds, or use a hand sanitizer with at least 60% alcohol.</li><li>Avoid motions that transfer organisms from your hands to your face. Your mouth, nose and eyes have mucous membranes that are potentially receptive to these organisms.</li><li>Clean frequently touched surfaces.</li><li>Do as much as possible outside and keep interactions with others short.</li><li>Fortify ventilation systems for more frequent air exchanges.</li><li>Curtail in-person holiday celebrations with those not in your household.</li></ol>
<p>Celebrations are <a href="https://www.theatlantic.com/ideas/archive/2020/11/covid-19-is-out-of-control-what-can-we-do/617097/" target="_blank" rel="noopener noreferrer">particularly challenging</a> because it's difficult for everyone to self-quarantine for the 14 days prior to the event. Also, events are typically inside rather than out; spacing of six feet may not be an option; ventilation systems in our energy-efficient homes are likely COVID-19-insufficient; and one cannot be masked while eating.</p><p>So for Thanksgiving, do a virtual gathering instead. Cook the same menu in different houses to promote a sense of sharing. Send e-cards to each other with a personal note and wish for a good holiday. Or do a Zoom call where all can speak and express thankfulness for the ability to still be able to connect this year.<br></p><p><a href="https://www.chicagotribune.com/columns/heidi-stevens/ct-heidi-stevens-i-was-hospitalized-with-covid-19-1116-20201116-3z3jt5dexneydhyun7lgm46uvm-story.html" target="_blank" rel="noopener noreferrer">It is not unusual</a> for COVID-19 patients to rage when they discover that those around them dismissed or downplayed the wisdom and experience of scientists and doctors about the realities of the pandemic. But there is no need to give up, even in the face of increasingly frightening statistics. Instead, now is the time we need to commit not just to ourselves, but to one another. What's standing in the way of curtailing the numbers of COVID-19 cases, hospitalizations and deaths is us.</p>

Humans aren't the only animals that get "hangry" when deprived of a meal.
<p>A new study published in <a href="https://www.cell.com/iscience/fulltext/S2589-0042(20)30988-3" rel="noopener noreferrer" target="_blank">iScience Thursday</a> found that <a href="https://www.ecowatch.com/tag/monarch-butterflies" target="_self">monarch butterfly</a> caterpillars (<em>Danaus plexippus</em>) will aggressively push each other out of the way when food gets scarce.</p><p>"The less food that is present, the higher their level of aggression," study coauthor Elizabeth Brown of Florida Atlantic University told <a href="https://institutions.newscientist.com/article/2260172-very-hangry-caterpillars-could-help-reveal-genetic-basis-of-aggression/" rel="noopener noreferrer" target="_blank">New Scientist</a>.</p><p>The idea for the study was born when the wife of fellow Florida Atlantic University researcher Alex Keene saw two monarch caterpillars fighting over a milkweed plant in the couple's garden, <a href="https://www.nytimes.com/2020/11/19/science/hungry-caterpillars-angry.html?campaign_id=51&emc=edit_NN_p_20201120&instance_id=24292&nl=morning-briefing&regi_id=88631294&section=whatElse&segment_id=45014&te=1&user_id=d8eb7cee9d3c5ab39515239b6ec54d19" target="_blank">The New York Times reported</a>.</p>
<p>"I decided to investigate monarch caterpillars because I was intrigued by their combative behavior, which I observed first-hand in my own garden," Keene explained in a <a href="http://www.fau.edu/newsdesk/articles/aggressive-monarch-caterpillars.php" target="_blank">Florida Atlantic University press release</a>. "They are large and easily recognizable compared to many other <a href="https://www.ecowatch.com/tag/insects" target="_self">insects</a>. These are charismatic animals that everyone loves, and there's a growing appreciation for their potential to tell us about how the brain controls behavior."</p><p>The researchers gave the caterpillars three different amounts of food, New Scientist reported. The less milkweed the caterpillars received, the more aggressive they became. The caterpillars who were larger and closer to metamorphosis were the most aggressive, probably because they required more energy, Brown said.</p><p>Caterpillar aggression looked like a "combination of boxing and 'bumper' cars," the press release detailed, with caterpillars head butting or knocking other caterpillars away from the food.</p>
<p>"I went to grad school with a guy who played rugby in college," Keene told The New York Times. "A flying head butt is a fair assessment."</p><p>The attacked caterpillar would then shuffle away from the food, defeated. This is a big problem for the losing caterpillar, since monarch caterpillars essentially eat non-stop from hatching to forming a cocoon.</p><p>The researchers hope to build on this study to learn more about the genetic drivers of aggressive behavior.</p><p>"There's a lot we could learn about more complex animals from this ecologically relevant insect model," Keene told New Scientist.</p>
<p>The research could also have <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> implications. Monarch caterpillars mainly dine on milkweed: They can strip an entire plant in two weeks and, when they are at their largest, consume a leaf in less than five minutes, the press release noted. But this dependence on milkweed has made the species vulnerable. The number of monarch butterflies has decreased in the U.S. over the last 20 years, according to the <a href="https://www.fws.gov/savethemonarch/" rel="noopener noreferrer" target="_blank">U.S. Fish and Wildlife Service</a>, and one factor is the use of <a href="https://www.ecowatch.com/tag/pesticides" target="_self">pesticides</a> that harm milkweed. <br></p><p>"It's interesting to think about how this would potentially impact the survival of these caterpillars, when they're crowded onto plants," University of Michigan monarch biologist D. André Green, who was not part of the study, told The New York Times. "The amount of milkweed is decreasing. This may become a bigger issue."</p>

As the Trump Administration’s Tiny Windows Close, Giant Doors Open for Science Advice
18 November
Insights + Opinion

By Genna Reed
In his first week as president-elect, Joe Biden instituted an advisory board of experts to provide science-based recommendations to respond to COVID-19. This could be a signal that independent science advice under a Biden administration is valued. After four years of watching the norms of science advisory structures eroded and undermined, especially at the EPA, it is hard to visualize the possibilities of a government informed by experts. Once Biden takes office in January, here are the actions I hope his administration will take to shore up the government's fifth arm of external expert advice:
1. Rescind EO 13875 and Reinstate Disbanded Committees
<p>In Executive Order 13875, titled "Evaluating and Improving the Utility of Federal Advisory Committees," issued in June 2019<strong>, </strong>President Trump mandated the elimination of one-third of federal advisory committees with an aim of <a href="https://blog.ucsusa.org/genna-reed/trump-executive-order-advisory-committee" target="_blank">reaching the arbitrary total of 350</a>. Some agencies followed the order, cutting committees like <a href="https://blog.ucsusa.org/genna-reed/the-first-cut-of-epa-advisory-committees-is-the-deepest" target="_blank">EPA's Environmental Laboratory Advisory Board (ELAB) and the National Advisory Council for Environmental Policy and Technology (NACEPT)</a>, <a href="https://thehill.com/policy/energy-environment/465001-trump-officials-eliminate-board-that-advised-on-smart-grid" target="_blank">The Department of Commerce's Smart Grid Advisory Committee</a> and <a href="https://blog.ucsusa.org/genna-reed/science-advice-shouldnt-be-at-the-whim-of-a-president-and-his-appointees" target="_blank">Marine Protected Areas Advisory Committee, and DOI's Invasive Species Advisory Committee</a> and CDC's <a href="https://www.atsdr.cdc.gov/science/" target="_blank">Agency for Toxic Substances and Disease Registry's Board of Scientific Counselors</a> and its <a href="https://www.facadatabase.gov/FACA/apex/FACAPublicCommittee?id=a10t0000001gzkCAAQ" target="_blank">Advisory Committee to the Director</a>. Yes, you read that right. As the CDC director responded to a national public health crisis, he did not have a sounding board of leading public health experts to help guide a federal response, as <a href="https://www.facadatabase.gov/FACA/apex/FACAPublicCommittee?id=a10t0000001gzkCAAQ" target="_blank">had been readily available since 1962</a>.</p><p>Neither the White House nor federal agencies released criteria or a full justification for disbanding these committees to the public. This is likely not an exhaustive list. Thus, the Biden administration should allow agencies to bring back disbanded committees quickly so that they can get back to work on projects left unfinished and take on new ones, especially those with direct relevance to providing expertise to the government on responding to COVID-19.</p>2. Issue a Proactive Executive Order to Affirm the Value of Advisory Committees
<p>The president-elect should issue an executive order affirming the value of advisory committees and direct agencies to improve the integrity and transparency of processes to ensure committees meet their chartered objectives. <a href="https://www.ucsusa.org/sites/default/files/2020-09/si-of-federal-advisory-committees.pdf" target="_blank">Our fact sheet</a> includes a long list of measures that should be included in that order, but the goal of the executive order should be threefold:</p><ul><li>address committee membership by requiring agencies to be more transparent and make decisions based solely on experience and technical qualifications in the topic the committees address, and not based on inappropriate criteria (e.g., party affiliation, political opinions, <a href="https://blog.ucsusa.org/michael-halpern/the-epa-science-advisory-board-is-being-compromised-heres-why-that-matters" target="_blank">having received a government grant</a>);</li><li>protect the independence and integrity of advisory committees by protecting against <a href="https://www.ucsusa.org/sites/default/files/2020-09/conflicts-of-interest-at-federal-agencies.pdf" target="_blank" rel="noopener noreferrer">conflicts of interest</a>;</li><li>ensure that the processes used to establish and terminate advisory committees are clear and transparent and that the government seeks out the advice it needs.</li></ul><p>An order that sets a high ethical bar for external advice can help protect against some of the more egregious violations we saw under the Trump administration, like the appointment of a majority of members with <a href="https://blog.ucsusa.org/genna-reed/biased-science-board-threatens-fetal-tissue-research" target="_blank" rel="noopener noreferrer">clear issues of impartiality to the HHS's Human Fetal Tissue Ethics Advisory Board,</a> which then issued sweeping rejections of grant proposals for critical research using fetal tissue.</p>3. Go Back to the Drawing Board at the EPA
<p>The Biden administration should begin to reverse the damage done by former Administrator Pruitt and Administrator Wheeler to <a href="https://thehill.com/opinion/energy-environment/512063-americans-need-the-best-science-more-than-ever-from-government" target="_blank">gerrymander science at EPA</a> and signal a commitment to balanced, independent advice by instituting a new nominations process for all EPA committees, while promoting transparency and public input and listening to its own staff recommendations. The administration should begin by scrapping the <a href="https://thehill.com/policy/energy-environment/521044-shuffle-of-epas-science-advisors-elevates-those-with-industry-tries" target="_blank">Science Advisory Board</a> and <a href="https://blog.ucsusa.org/gretchen-goldman/the-epa-cut-science-out-of-air-pollution-standard-setting-were-putting-it-back" target="_blank">the Clean Air Scientific Advisory Committee</a> and start over. Here's why.</p><p>There are still qualified experts on EPA's advisory committees, but since the <a href="https://blog.ucsusa.org/genna-reed/epas-chance-to-get-science-advice-right" target="_blank">process barred EPA-funded scientists from applying from fall 2017 to 2020</a>, the expertise is not balanced and not the most relevant for the issues currently facing EPA. Further, it is unclear whether membership was adequately vetted for conflicts of interest. These are all fair questions, since <a href="https://www.gao.gov/products/GAO-19-280" target="_blank" rel="noopener noreferrer">we know Wheeler's administration failed to provide documentation on its selection process</a>.</p><p>The only way to fix a broken process is to start from scratch, instituting some of the norms and processes that were in place before the Trump administration came in, but also updating them to ensure even more transparency. For example, <a href="https://www.ucsusa.org/sites/default/files/2020-09/si-of-federal-advisory-committees.pdf" target="_blank" rel="noopener noreferrer">we recommend</a> that all agencies, including EPA, publish relevant basic information about each committee member on a public online portal (e.g., integrity.gov), including qualifications, background, employers, and funding sources for the previous five years, along with any conflict-of-interest waivers granted. Additionally, the decisionmaking processes used for committee formation, including how agencies screen members, how they assess committees for balance, and which political officials are involved, should be made public.</p><p>All members of committees re-formed could reapply if they wished to remain. But importantly, a new vetting process would ensure that expertise was prioritized and that conflicts of interest or appearance of impartiality was avoided.</p>4. Work With Congress on Bipartisan Legislation That Would Increase Transparency and Public Input
<p>The <a href="https://blog.ucsusa.org/andrew-rosenberg/improving-transparency-and-disclosure-of-conflicts-of-interest-for-science-advisory-committees" target="_blank">Federal Advisory Committee Act Amendments of 2019</a> would require agencies to open nominations for committee positions, select and publicize from those nominations, and clearly distinguish independent scientists from those representing a particular interest group. The bill would also require disclosure of conflicts of interest to the agency and the public and greater transparency of the meetings themselves. Also, political party affiliation cannot be used as a criterion for selection for a committee, which is important as such political litmus tests have been used in the past to <a href="https://www.ucsusa.org/center-for-science-and-democracy/scientific_integrity/abuses_of_science/a-to-z/fogarty-international-center.html" target="_blank">distort and stack</a> advisory committees under previous administrations.</p><p>Congress could also consider legislation that would institute a formal petition process for the public to request an agency assemble a federal advisory committee for an issue based on a set of criteria. This could ensure a more inclusive and equitable approach to deciding what issues get paid adequate attention by agencies.</p>Making a Sound Investment in Science Advice
<p>We have studied the ways in which science advisory committees have been sidelined or hijacked and over the past four years saw very clearly how changes to norms and the erosion of processes built to uphold integrity can wreak havoc on environmental and public health policy decisions.</p><p>As a new administration takes office, I hope that it takes advantage of this hindsight and sees the opportunities I see: not just bringing back old policies and signaling the importance of government science advice, but finding new ways to make it more responsive to the public than to special interests, and more inclusive of a diverse set of scientists and experts whose voices need to be heard right now. There's no time like the present to modernize our government advisory infrastructure, and <a href="https://www.ucsusa.org/sites/default/files/2020-09/si-of-federal-advisory-committees.pdf" target="_blank">our recommendations feature actions that can help get us there.</a></p>From Your Site Articles
