Rising temperatures in the air and the water surrounding Greenland are melting its massive ice sheet at a faster rate than anytime in the last 12 millennia, according to a new study published Wednesday in the journal Nature.
<p>The study, <em>Rate of mass loss from the Greenland Ice Sheet will exceed Holocene values this century</em>, found that while Greenland is losing ice rapidly now, the worst is yet to come. At its current trajectory, the Greenland ice sheet will lose its ice mass roughly four times faster than at anytime in the last 11,700 years. The researchers say the massive dump of freshwater into the <a href="http://www.ecowatch.com/tag/oceans" target="_self">ocean</a> will disrupt the ocean's currents and <a href="http://www.ecowatch.com/tag/sea-level-rise" target="_self">raise sea levels</a>, as <a href="https://www.washingtonpost.com/weather/2020/09/30/greenland-ice-melt/" target="_blank" rel="noopener noreferrer">The Washington Post</a> reported.</p><p>Advanced prediction models had led scientists to conclude that Greenland's melting ice, which is currently the largest contributor to sea level rise, is raising sea levels by 0.7 millimeters each year. And, by the end of the century, that number could increase anywhere from four to ten times its current contribution.</p>
<p>This new paper found that prediction to be a severe underestimation. It revised that prediction and accounted for a wide range of greenhouse gas emissions to conclude that Greenland's contribution to sea level rise will actually be much worse. By the end of the century, it will lift sea levels between 2 to 10 centimeters every year, according to a commentary in <a href="https://www.nature.com/articles/d41586-020-02700-y#:~:text=Briner%20et%20al.4%20have,about%206%2C000%20gigatonnes%20per%20century." target="_blank"><em>Nature</em></a>.</p><p>The Washington Post noted that while Greenland is the largest contributor to rising sea levels, the melting ice sheets in <a href="http://www.ecowatch.com/tag/antarctica">Antarctica</a> may raise sea levels even more.</p><p>"We have altered our planet so much that the rates of ice sheet melt this century are on pace to be greater than anything we have seen under natural variability of the ice sheet over the past 12,000 years," said Jason Briner, a geologist at the University of Buffalo and lead author of the paper, as <a href="https://www.theguardian.com/world/2020/sep/30/greenlands-ice-melting-faster-sea-level-rise" target="_blank">The Guardian</a> reported.</p>
<p>Briner pointed out that the current ice melt is not due to the natural variability, which is why it is so different from historical patterns. This melting is strictly man-made, which is unprecedented in the history of the world, as <a href="https://www.cnn.com/2020/09/30/weather/greenland-ice-sheet-melt-carbon-emissions-climate-change/index.html" target="_blank">CNN</a> reported.</p><p>The commentary in <em>Nature</em>, written by Andy Aschwanden from the Geophysical Institute at the University of Alaska Fairbanks, noted that there is really only one way available to us to stop the acceleration of sea ice loss from Greenland.</p><p>"Thanks to the work of Briner and colleagues, we are now one step closer to the goal of accurately and confidently predicting mass loss from the Greenland ice sheet," Aschwanden concluded. "However, we are also increasingly certain that we are about to experience unprecedented rates of ice loss from Greenland, unless greenhouse-gas emissions are substantially reduced."</p><p>To conduct the research, the scientists used a combination of on-the-ground observations in southwest Greenland and advanced computer modeling. The geologists looked at the composition of Greenland's boulders to determine when ice was there and when it melted away. That analysis allowed them to put together an uninterrupted history of Greenland's ice sheet and a predictive model for the next century, as The Washington Post reported.</p>

A grim new assessment of the world's flora and fungi has found that two-fifths of its species are at risk of extinction as humans encroach on the natural world, as The Guardian reported. That puts the number of species at risk near 140,000.
<p>The new report, <a href="https://www.kew.org/sites/default/files/2020-09/Kew%20State%20of%20the%20Worlds%20Plants%20and%20Fungi.pdf" target="_blank" rel="noopener noreferrer">State of the World's Plants and Fungi 2020</a>, and an accompanying <a href="https://youtu.be/fTHKjZyuUos" rel="noopener noreferrer" target="_blank">short video</a> were published by Royal Botanic Gardens Kew, and depict an international effort from hundreds of scientists from 42 countries who analyzed the health of thousands of animal species. The researchers looked at how people are interacting with plants, how plants and fungi are being used, and what opportunities people are missing, as <a href="https://www.irishtimes.com/news/world/two-fifths-of-world-s-plants-at-risk-of-extinction-report-warns-1.4368362" rel="noopener noreferrer" target="_blank">The Irish Times</a> reported.</p>
<p>The report highlights that plants are crucial to sustaining life as they provide food, medicine, raw materials, fuel and food. And yet, the report notes, "Never before has the biosphere, the thin layer of life we call home, been under such intensive and urgent threat. Deforestation rates have soared as we have cleared land to feed ever-more people, global emissions are disrupting the climate system, new pathogens threaten our crops and our health, illegal trade has eradicated entire plant populations, and non-native species are outcompeting local floras. <a href="http://www.ecowatch.com/tag/biodiversity">Biodiversity</a> is being lost – locally, regionally and globally."</p><p>The report notes that scientists are racing against the clock to rescue plant and fungi species and they are also working to figure out how to leverage plants and fungi to combat the <a href="https://www.ecowatch.com/tag/climate-crisis">climate crisis</a> and food insecurity, according to the <a href="https://www.bbc.com/news/science-environment-54344309" target="_blank">BBC</a>.</p>
<p>When Kew issued its first report in 2016, it found that 20 percent of plant species were at risk. That number has doubled in just four years. However, that does not mean that twice as many plant species are at risk. Instead, the huge jump in percentage is due to advances in assessments that now make a more accurate account for plants that were over- or underrepresented in the 2016 report, according to The Irish Times.</p><p>The fact that 40 percent of plant species are at risk paints "a very worrying picture of risk and urgent need for action," according to Alexandre Antonelli, director of science at Royal Botanic Gardens Kew, as The Irish Times reported.</p>
<p>"We are also losing the race against time, species are probably disappearing faster than we can find and name, and many of them could hold important clues for solving many of the pressing challenges of medicine and perhaps even some of the emerging or current pandemics," he added.</p><p>The scientists involved in the research noted that more than 4,000 plant and fungi species were discovered last year. These plants are an untapped resource that holds tremendous promise as food, medicine and biofuels, according to the paper, as The Guardian reported. Some of the new species discovered include members of the onion family, plants similar to spinach, and relatives of the staple crop cassava.</p>
<p>Around the world, billions depend on plants as their primary source of medicine. The report noted that 723 species used as therapeutic treatments are threatened with extinction.</p><p>"We would not be able to survive without plants and fungi. All life depends on them, and it is really time to open the treasure chest," said Antonelli, as The Guardian reported. "Every time we lose a species, we lose an opportunity for humankind."</p>

Flowers like bladderwort have changed their UV pigment levels in response to the climate crisis. Jean and Fred / CC BY 2.0
As human activity transforms the atmosphere, flowers are changing their colors.
<p>A study published in <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(20)31267-7?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0960982220312677%3Fshowall%3Dtrue" target="_blank">Current Biology this month</a> found that the ultraviolet (UV) pigmentation of certain flowers had changed in response to the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a> and the depletion of the <a href="https://www.ecowatch.com/tag/ozone" target="_self">ozone</a> layer. While this isn't something that would be visible to the human eye, flowers rely on their UV patterns to attract <a href="https://www.ecowatch.com/tag/pollinators" target="_self">pollinators</a>. If those patterns change, it could seriously impact the ability of <a href="https://www.ecowatch.com/tag/plants" target="_self">plants</a> to reproduce.</p><p>"This has implications for plant reproduction of both native wildflowers and domesticated crop species that have UV floral patterning like canola and sunflowers," study coauthor and Clemson University scientist Matthew Koski told the <a href="https://newsstand.clemson.edu/mediarelations/researcher-travels-world-to-measure-how-climate-change-is-altering-the-color-of-flowers/" target="_blank">Clemson Newsstand</a>. "Altered UV floral coloration has the potential to disrupt pollination services."</p>
<p>To achieve his results, Koski traveled to Europe, Australia and North America and collected plant specimens dating from the 1940s to 2017. All in all, he and his team looked at 1,238 specimens to see how and if their UV pigmentation had responded to changes in UV exposure and temperature.</p><p>Overall, they found that UV pigmentation increased by two percent each year. This makes sense because flowers use UV pigment to protect their pollen from UV radiation, <a href="https://www.sciencemag.org/news/2020/09/flowers-are-changing-their-colors-adapt-climate-change#:~:text=Now%2C%20research%20suggests%20that%20over,UV)%20pigments%20in%20their%20petals" target="_blank">Science explained</a>. In an earlier study, Koski had found that flowers living in areas with more UV exposure, such as higher altitudes, had more UV pigment. This finding matched the researchers' prediction that flowers would evolve to make more pigment as ozone levels declined and UV radiation exposure increased.</p><p>However, the flowers' responses to both ozone and temperature changes were heavily influenced by whether the flowers had exposed pollen or not, Science explained.</p>
<p><strong>Flowers With Exposed Pollen:</strong> For these saucer-shaped flowers, like buttercups, UV pigmentation went up when ozone declined and went down when ozone rose.</p><p><strong>Flowers with Concealed Pollen:</strong> For these flowers, such as bladderwort, UV pigment levels were determined by temperature, not radiation exposure. If temperature went up, pigment levels fell, even if ozone levels also declined.</p><p>This is because concealing pollen in petals can protect it from UV exposure but also expose it to additional heat, Harvard plant biologist Charles Davis, who was not involved with the study, told Science. When temperatures rise, the extra protection risks overheating the pollen. Reducing UV pigment also reduces the amount of solar radiation the petals absorb and can therefore help keep pollen cool.</p><p>Pigment changes could impact plants' ability to attract pollinators because pollinators are attracted by a "bull's-eye" pattern that contrasts high and low UV pigment, Koski explained. Altering pigment levels could also alter the effectiveness of this pattern.</p><p>Koski told the Clemson Newsstand he hopes to continue his research, in part by investigating further how changes in flower pigmentation will impact their ability to attract pollinators. He also hopes to determine if changes to ozone and temperature alter flowers' visible hues.</p>

Back in March, when the pandemic had just planted its roots in the U.S., President Donald Trump directed the Environmental Protection Agency (EPA) to do something devastating: The agency was to indefinitely and cruelly suspend environmental rule enforcement. The EPA complied, and for just under half a year, it provided over 3,000 waivers that granted facilities clemency from state-level environmental rule compliance.
<p>These rule suspensions ended last month, but they almost undoubtedly caused an <a href="https://grist.org/justice/the-epa-cut-back-enforcement-during-covid-these-researchers-are-assessing-the-damage/" target="_blank">increase in pollution rates</a>, as one preliminary study <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3633446" target="_blank">already found</a>. What's worse is that we'll likely never know the full extent of the damage, as the agency also suspended rules for self-monitoring (and even before the pandemic <a href="https://truthout.org/articles/trumps-epa-is-unleashing-the-pollution-that-makes-us-vulnerable-to-covid-19/" target="_blank">monitoring was already limited</a>). Analysts at the Environmental Data and Governance Initiative found that, in March and April, industrial polluters <a href="https://envirodatagov.org/more-permission-to-pollute-the-decline-of-epa-enforcement-and-industry-compliance-during-covid/" target="_blank">conducted 40 percent fewer tests</a> compared to the same time in 2019, according to self-reported data.</p><p>In a country where pollution impacts are <a href="https://www.npr.org/sections/health-shots/2019/03/11/702348935/study-finds-racial-gap-between-who-causes-air-pollution-and-who-breathes-it" target="_blank">disproportionately impactful</a>, the suspension of pollution rules in the middle of a respiratory illness outbreak is unconscionable — <a href="https://projects.iq.harvard.edu/covid-pm" target="_blank" rel="noopener noreferrer">several studies</a> have found that higher pollution exposure can lead to <a href="https://iopscience.iop.org/article/10.1088/1748-9326/abaf86/pdf" target="_blank" rel="noopener noreferrer">higher rates of death</a> due to COVID-19.</p><p>But, given the stark differences between racial groups when it comes to pollution exposure and effects, the temporary policy is downright racist. A 2018 study from the EPA itself found that, respectively, Black and Latinx communities were <a href="https://www.theatlantic.com/politics/archive/2018/02/the-trump-administration-finds-that-environmental-racism-is-real/554315/" target="_blank">exposed to 1.5 and 1.2 times</a> more particulate matter, a pollutant that can cause damage to the respiratory system, than white communities. Another study published in the <em>New England Journal of Medicine</em> in 2017 found that Black people were <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1702747" target="_blank">three times more likely</a> to die from exposure to particulate matter than the overall population.</p><p>Under Trump, federal climate policy has only become less and less stringent — The <em>New York Times </em>has documented <a href="https://www.nytimes.com/interactive/2020/climate/trump-environment-rollbacks.html" target="_blank">100 environmental rollbacks</a> thus far. Such rollbacks are bad news for everyone, but they're especially harmful for Black and minority communities, which have <a href="https://www.npr.org/sections/health-shots/2019/03/11/702348935/study-finds-racial-gap-between-who-causes-air-pollution-and-who-breathes-it" target="_blank" rel="noopener noreferrer">borne the brunt</a> of pollution for decades.</p><p>The fact that Black and brown people suffer most under environmental degradation is not news. But the dilemmas remain in the environmental justice community as they have for many years: How do we lessen the climate burden on Black and oppressed communities? How can we achieve equitable and drastic emissions reductions and transform our entire economy before the window of opportunity to prevent irreversible climate change closes?</p>
<p>For decades, one of the only legal tools available to an environmental justice advocate was the National Environmental Policy Act, or NEPA, was written in the late 1960s in response to historical disasters like oil spills and injustices like the destruction of poor neighborhoods to build highways. Over the years, NEPA has been an extraordinary useful framework for communities to lessen or prevent environmental impacts of federal projects — in 2018, <a href="https://truthout.org/articles/trumps-latest-attack-on-the-environment-may-be-his-most-alarming-yet/" target="_blank">a judge cited NEPA</a> when they blocked the Trump administration's attempt to fast-track the Keystone XL pipeline.<br></p><p>While NEPA has helped <a href="https://www.nrdc.org/resources/never-eliminate-public-advice-nepa-success-stories" target="_blank">countless communities</a> in protecting against potentially harmful impacts, however, it also has major limitations. Though NEPA forces agencies to consider the potential impacts of a project, it doesn't require stopping or even mitigating those impacts. This is partially what has allowed polluters to choke out disproportionately Black communities like Louisiana's "<a href="https://truthout.org/articles/petrochemical-giants-are-slowly-killing-black-louisiana-communities/" target="_blank">Cancer Alley</a>" and New York City's "<a href="https://www.theguardian.com/us-news/2019/apr/04/new-york-south-bronx-minorities-pollution-inequity#:~:text=The%20park%20is%20a%20little,pollution%20levels%20in%20the%20US." target="_blank">Asthma Alley</a>" in the past decades. Early this year, the Trump administration radically <a href="https://truthout.org/articles/trumps-latest-attack-on-the-environment-may-be-his-most-alarming-yet/" target="_blank">rewrote NEPA</a> so that it would give more power to polluters, limiting public input on projects and eliminating the consideration of cumulative impacts.</p><p>"A big challenge is the way that NEPA intersects with other racist policies like redlining and things that existed prior to NEPA," says <a href="https://www.americanprogress.org/person/hardin-sally/" target="_blank">Sally Hardin</a>, who formerly worked on the council that oversees NEPA and is the interim director on energy and environment at the Center for American Progress (CAP). While NEPA is a tool that communities can use to challenge projects such as the construction of a new oil refinery, the process requires time and resources that many can't afford; poor neighborhoods that can't afford to hire lawyers to review legalese or where citizens don't have time to show up to public hearings are more likely to find themselves with a new refinery than a wealthy neighborhood.</p><p>When communities do have the time and resources to oppose a project, though, states will find a different way to get around them. <a href="https://www.propublica.org/article/how-louisiana-lawmakers-stop-residents-efforts-to-fight-big-oil-and-gas" target="_blank">Legislators in Louisiana</a>, for instance, who often receive financial incentives from oil and gas companies and chemical manufacturers, have attempted to outlaw protests against these projects.</p><p>So, while environmental advocates can use NEPA as a tool to further justice, entrenched racial and class disparities in the U.S. will be extremely difficult to undo, no matter the policy or politician. To <a href="https://www.weact.org/person/peggy-shepard/" target="_blank" rel="noopener noreferrer">Peggy Shepard</a>, the executive director of WE ACT for Environmental Justice, the problem presents itself before NEPA can even come into the equation. Part of the issue, Shepard says, lies in permitting.</p>
<p>"You could have numbers of facilities emitting air toxins, numbers of facilities impacting water quality, facilities impacting soil contamination, a number of waste transfer facilities all in one community," says Shepard. "And because you're only permitting [pollution type by pollution type], you would say, 'Well, we've got one waste transfer station and it's okay, it's in compliance.' But what does it do when you've got water contamination, soil contamination, air quality, toxins? What's that soup?"</p><p>Yet another issue lies in unequal enforcement of certain laws, especially along financial lines — a 2009 study found that agencies <a href="https://www.jstor.org/stable/29738988" target="_blank" rel="noopener noreferrer">did not enforce crucial pollution laws</a> in poor counties as much as richer counties.</p><p>And, in some ways, unequal enforcement can be built into the laws themselves. For instance, as Climate and Energy Policy director at the Union of Concerned Scientists <a href="https://www.ucsusa.org/about/people/rachel-cleetus" target="_blank">Rachel Cleetus</a> raises, the Army Corps determines and allocates resources for defensive measures for such events as flooding using a cost-benefit analysis. That analysis benefits richer communities because the market value of the property being lost is higher.</p>
<p>"There are lots of ways in which you can have neutral-sounding laws, but if you don't get out some of these underlying things and specifically target resources to set them right in some way, you're gonna end up with skewed outcomes," says Cleetus.</p><p>In Congress, some legislators are working to solve some of these problems at a federal level. Last month, Rep. Alexandria Ocasio-Cortez (D-New York) and Sen. Kamala Harris (D-California) introduced the Climate Equity Act, which would introduce the Office of Climate and Environmental Justice Accountability within the Office of Management and Budget and require relevant agencies to appoint a director of environmental justice. It would also require environmental legislation to come with an "<a href="https://thehill.com/policy/energy-environment/510920-harris-aoc-push-climate-equity-bill-with-green-new-deal-roots" target="_blank" rel="noopener noreferrer">equity score</a>" that rates the impact of the legislation on frontline and poor communities.</p><p>"The difficulty [with the equity score] comes in defining who those communities should be and how (and that definition should ABSOLUTELY be created by, and with, the impacted communities themselves)," says Hardin in an email to <em>Truthout</em>. The Climate Equity Act was crafted from advice from environmental justice coalitions, and though the bill likely won't pass soon, coalitions and communities most impacted must have a say in the process.</p>
<p>Though there are many hurdles to yet to clear, environmental justice movements have been making big moves across the country in the past few years. Initiatives like the <a href="https://ajustclimate.org/" target="_blank">Equitable and Just National Climate Platform</a> and the <a href="https://grist.org/justice/an-effort-to-bring-environmental-justice-for-all-goes-virtual/" target="_blank">Environmental Justice for All Act</a> have gained momentum among Democrats; and local groups are getting the attention of politicians to address some of the largest hurdles — permitting, unfair lawmaking and gaining grassroots political power.</p><p>Last week, Gov. Phil Murphy (D-New Jersey) signed an environmental justice law unlike any other in the country: Despite <a href="https://www.politico.com/states/new-jersey/story/2020/08/27/new-jersey-legislature-sends-groundbreaking-environmental-justice-bill-to-governors-desk-1313030" target="_blank">powerful industry opposition</a> that stalled the bill for years, the new state law will <em>require</em> permits for projects like power plants and landfills to be rejected if they are to be cited in an already overburdened neighborhood. Other states require agencies to merely <em>consider</em> cumulative impacts in the permitting process with no mandate to act on that consideration — formerly, NEPA required all government-funded projects to consider cumulative impacts, but the Trump administration, in its <a href="https://truthout.org/articles/trumps-latest-attack-on-the-environment-may-be-his-most-alarming-yet/" target="_blank" rel="noopener noreferrer">gutting of NEPA</a> this year, rolled that rule back.</p><p>The bill was passed due to the tireless work of grassroots activists and environmental justice groups — Ironbound Community Corporation, New Jersey Environmental Justice Alliance and <a href="https://www.cleanwateraction.org/releases/new-jersey-sets-national-precedent-environmental-justice-bill-signing-today" target="_blank" rel="noopener noreferrer">Clean Water Action</a> — who fought <a href="https://www.politico.com/states/new-jersey/story/2020/08/27/new-jersey-legislature-sends-groundbreaking-environmental-justice-bill-to-governors-desk-1313030" target="_blank" rel="noopener noreferrer">chemical and waste industry lobbyists</a> and <a href="https://www.northjersey.com/story/news/environment/2019/11/07/phil-murphy-preaches-environmental-justice-nj-but-his-actions-say-different-ford-ringwood-keegan/4124093002/" target="_blank" rel="noopener noreferrer">Murphy's administration</a> to push the bill through.</p>
<p>Grassroots and activist groups <a href="https://insideclimatenews.org/news/31082020/candidate-profile-joe-biden-climate-change-election-2020" target="_blank">have helped</a> Joe Biden better his climate platform, too, as he unveiled a new plan in July — his <a href="https://insideclimatenews.org/news/31082020/candidate-profile-joe-biden-climate-change-election-2020" target="_blank">environmental justice plan</a> is surprisingly good for candidate whose climate plan as a whole got an "F" from the Sunrise Movement last year. The plan includes creating and elevating climate justice divisions in the federal government and the White House, mandate pollution monitoring in frontline communities — which is currently <a href="https://truthout.org/articles/trumps-epa-is-unleashing-the-pollution-that-makes-us-vulnerable-to-covid-19/" target="_blank">notoriously terrible</a> — and spend 40 percent of the overall investments in the climate plan on disadvantaged communities.</p><p>Several of the initiatives outlined in Biden's plan are extensions of what the Obama administration already got started — expanding the <a href="https://www.epa.gov/ejscreen" target="_blank">EPA's EJSCREEN tool</a> that identifies environmental justice hotspots, for instance. This is progress that should have been made years ago — and progress that could have been made under a different administration.</p><p>But Trump has reversed much of the progress on climate that the country has made not only since the Obama administration, but also from <a href="https://truthout.org/articles/trumps-latest-attack-on-the-environment-may-be-his-most-alarming-yet/" target="_blank" rel="noopener noreferrer">decades ago</a> — including outright eliminating funding for environmental justice at the EPA. From here, as the climate crisis rages on, progress will be ever more vital to make. And, despite Biden's progress in climate over the course of the election, climate activists <a href="https://truthout.org/articles/joe-biden-pays-lip-service-to-climate-but-has-fallen-short-on-action/" target="_blank" rel="noopener noreferrer">have their work cut out for them</a> – no matter who's in office come January.</p>

A meteoroid skims the earth's atmosphere on Sept. 22, 2020. European Space Agency
A rare celestial event was caught on camera last week when a meteoroid "bounced" off Earth's atmosphere and veered back into space.
<p>The "Earthgrazer" was filmed early Sept. 22 over Northern Germany and the Netherlands, the <a href="https://www.esa.int/ESA_Multimedia/Images/2020/09/Lucky_meteoroid_skims_Earth_s_atmosphere" target="_blank">European Space Agency (ESA) reported</a>. It reached as low as 91 kilometers (approximately 56.4 miles), which is below the average satellite. At this point, most space rocks enter the atmosphere and turn into meteors, which we see as shooting stars. They usually disintegrate before they reach the ground, though sometimes pieces land as meteorites.</p><p>"This lucky visitor, however, didn't get low enough to completely burn up and managed to escape again, only grazing the edges of our planet's protective gassy shield," the ESA explained.</p>
<div id="a566f" class="rm-shortcode" data-rm-shortcode-id="95190b9c195f4d975a5f058cfa4d0588"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1308553949255999489" data-partner="rebelmouse"><div style="margin:1em 0">(1/2) An earthgrazer above N Germany and the Netherlands was observed by 8 #globalmeteornetwork cameras on Sept 22,… https://t.co/zEe8QERBdQ</div> — Denis Vida (@Denis Vida)<a href="https://twitter.com/meteordoc/statuses/1308553949255999489">1600818547.0</a></blockquote></div>
<p>Meteoroids are bits of comet or asteroid that become detached from their parent bodies. While meteors streak across the sky thousands of times a year, Earthgrazing meteoroids only nick our atmosphere a few times annually. To bounce off the atmosphere, they need to approach it at a shallow angle and briefly enter it before shooting off again, <a href="https://www.universetoday.com/148041/video-shows-a-meteoroid-skipping-off-earths-atmosphere/" target="_blank">Universe Today explained</a>. The motion is similar to a rock skipping off a lake.</p><p>The rare event was caught on camera by the <a href="https://globalmeteornetwork.org/" target="_blank">Global Meteor Network</a> (GMN), which seeks to assemble a network of video cameras to observe meteors.</p><p>"The network is basically a decentralised scientific instrument, made up of amateur astronomers and citizen scientists around the planet each with their own camera systems," GMN founder and Western University in Ontario postdoc Denis Vida told the ESA.

Hanako, a female Asian elephant, lived in a tiny concrete enclosure at Japan's Inokashira Park Zoo for more than 60 years, often in chains, with no stimulation. In the wild, elephants live in herds, with close family ties. Hanako was solitary for the last decade of her life.
<p><a href="https://whalesanctuaryproject.org/whales/kiska-alone-again/" target="_blank" rel="noopener noreferrer">Kiska</a>, a young female orca, was captured in 1978 off the Iceland coast and taken to Marineland Canada, an aquarium and amusement park. Orcas are social animals that live in family <a href="https://www.nationalgeographic.com/animals/mammals/o/orca/" target="_blank" rel="noopener noreferrer">pods</a> with up to 40 members, but Kiska has lived alone in a small tank since 2011. Each of her five calves died. To combat stress and boredom, she swims in slow, endless circles and has gnawed her teeth to the pulp on her concrete pool.</p><p>Unfortunately, these are common conditions for many large, captive mammals in the "entertainment" industry. In decades of <a href="https://scholar.google.com/citations?user=KvCW9T0AAAAJ&hl=en" target="_blank">studying the brains of humans, African elephants, humpback whales and other large mammals</a>, I've noted the organ's great sensitivity to the environment, including serious impacts on its structure and function from living in captivity.</p>

Affecting Health and Altering Behavior
<p>It is easy to observe the overall health and psychological consequences of life in captivity for these animals. Many captive elephants suffer from arthritis, obesity or skin problems. Both <a href="https://doi.org/10.11609/JoTT.o2620.1826-36" target="_blank">elephants</a> and orcas often have severe dental problems. Captive orcas are plagued by <a href="https://doi.org/10.1016/j.jveb.2019.05.005" target="_blank">pneumonia, kidney disease, gastrointestinal illnesses and infections</a>.</p><p>Many animals <a href="https://doi.org/10.1016/j.neubiorev.2017.09.010" target="_blank">try to cope</a> with captivity by adopting abnormal behaviors. Some develop "<a href="https://doi.org/10.1016/j.applanim.2017.05.003" target="_blank" rel="noopener noreferrer">stereotypies</a>," which are repetitive, purposeless habits such as constantly bobbing their heads, swaying incessantly or chewing on the bars of their cages. Others, especially big cats, pace their enclosures. Elephants rub or break their tusks.</p>Changing Brain Structure
<p>Neuroscientific research indicates that living in an impoverished, stressful captive environment <a href="https://doi.org/10.1016/j.jveb.2019.05.005" target="_blank" rel="noopener noreferrer">physically damages the brain</a>. These changes have been documented in many <a href="https://doi.org/10.1002/cne.903270108" target="_blank" rel="noopener noreferrer">species</a>, including rodents, rabbits, cats and <a href="https://doi.org/10.1006/nimg.2001.0917" target="_blank" rel="noopener noreferrer">humans</a>.</p><p>Although researchers have directly studied some animal brains, most of what we know comes from observing animal behavior, analyzing stress hormone levels in the blood and applying knowledge gained from a half-century of neuroscience research. Laboratory research also suggests that mammals in a zoo or aquarium have compromised brain function.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQ1MDQzNC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1MjM0MzI1MH0.fp2ujwrgKdMD09Y4jRTH8cUUCyxtcAmp0M30n4LzHIU/img.jpg?width=980" id="7cb37" class="rm-shortcode" data-rm-shortcode-id="4c195010067513dfa086c5a0dba564bc" data-rm-shortcode-name="rebelmouse-image" />
This illustration shows differences in the brain's cerebral cortex in animals held in impoverished (captive) and enriched (natural) environments. Impoverishment results in thinning of the cortex, a decreased blood supply, less support for neurons and decreased connectivity among neurons. Arnold B. Scheibel, CC BY-ND
<p>Subsisting in confined, barren quarters that lack intellectual stimulation or appropriate social contact seems to <a href="https://doi.org/10.1590/S0001-37652001000200006" target="_blank" rel="noopener noreferrer">thin the cerebral cortex</a> – the part of the brain involved in voluntary movement and higher cognitive function, including memory, planning and decision-making.</p><p>There are other consequences. Capillaries shrink, depriving the brain of the oxygen-rich blood it needs to survive. Neurons become smaller, and their dendrites – the branches that form connections with other neurons – become less complex, impairing communication within the brain. As a result, the cortical neurons in captive animals <a href="https://doi.org/10.1002/cne.901230110" target="_blank">process information less efficiently</a> than those living in <a href="https://doi.org/10.1002/dev.420020208" target="_blank">enriched, more natural environments</a>.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQ1MDQzOC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYwOTY3ODY3NX0.LMeqPwRQnd-zr0FF0JcAEVZ9FC0gAy9uzrnb_aXK99o/img.jpg?width=980" id="2bc51" class="rm-shortcode" data-rm-shortcode-id="d34c18b3323cc4c9f41bbe18d8b5aaf1" data-rm-shortcode-name="rebelmouse-image" />

<p>Brain health is also affected by living in small quarters that <a href="https://doi.org/10.3233/BPL-160040" target="_blank">don't allow for needed exercise</a>. Physical activity increases the flow of blood to the brain, which requires large amounts of oxygen. Exercise increases the production of new connections and <a href="http://dx.doi.org/10.1126/science.aaw2622" target="_blank">enhances cognitive abilities</a>.</p><p>In their native habits these animals must move to survive, covering great distances to forage or find a mate. Elephants typically travel anywhere from <a href="https://www.elephantsforafrica.org/elephant-facts/#:%7E:text=How%20far%20do%20elephants%20walk,km%20on%20a%20daily%20basis." target="_blank">15 to 120 miles per day</a>. In a zoo, they average <a href="https://doi.org/10.1371/journal.pone.0150331" target="_blank" rel="noopener noreferrer">three miles daily</a>, often walking back and forth in small enclosures. One free orca studied in Canada swam <a href="https://doi.org/10.1007/s00300-010-0958-x" target="_blank" rel="noopener noreferrer">up to 156 miles a day</a>; meanwhile, an average orca tank is about 10,000 times smaller than its <a href="https://www.cascadiaresearch.org/projects/killer-whales/using-dtags-study-acoustics-and-behavior-southern" target="_blank" rel="noopener noreferrer">natural home range</a>.</p>Disrupting Brain Chemistry and Killing Cells
<p>Living in enclosures that restrict or prevent normal behavior creates chronic frustration and boredom. In the wild, an animal's stress-response system helps it escape from danger. But captivity traps animals with <a href="https://doi.org/10.1073/pnas.1215502109" target="_blank">almost no control</a> over their environment.</p><p>These situations foster <a href="https://doi.org/10.1037/rev0000033" target="_blank">learned helplessness</a>, negatively impacting the <a href="https://doi.org/10.1155/2016/6391686" target="_blank" rel="noopener noreferrer">hippocampus</a>, which handles memory functions, and the <a href="https://doi.org/10.1016/j.neuropharm.2011.02.024" target="_blank" rel="noopener noreferrer">amygdala</a>, which processes emotions. Prolonged stress <a href="https://doi.org/10.3109/10253899609001092" target="_blank" rel="noopener noreferrer">elevates stress hormones</a> and <a href="https://doi.org/10.1523/JNEUROSCI.10-09-02897.1990" target="_blank" rel="noopener noreferrer">damages or even kills neurons</a> in both brain regions. It also disrupts the <a href="https://doi.org/10.1016/j.neubiorev.2005.03.021" target="_blank" rel="noopener noreferrer">delicate balance of serotonin</a>, a neurotransmitter that stabilizes mood, among other functions.</p><p>In humans, <a href="https://doi.org/10.1006/nimg.2001.0917" target="_blank" rel="noopener noreferrer">deprivation</a> can trigger <a href="https://doi.org/10.3389/fnins.2018.00367" target="_blank" rel="noopener noreferrer">psychiatric issues</a>, including depression, anxiety, <a href="https://doi.org/10.3389/fnins.2018.00367" target="_blank" rel="noopener noreferrer">mood disorders</a> or <a href="https://doi.org/10.1177/1073858409333072" target="_blank" rel="noopener noreferrer">post-traumatic stress disorder</a>. <a href="https://doi.org/10.1007/s00429-010-0288-3" target="_blank" rel="noopener noreferrer">Elephants</a>, <a href="https://doi.org/10.1371/journal.pbio.0050139" target="_blank" rel="noopener noreferrer">orcas</a> and other animals with large brains are likely to react in similar ways to life in a severely stressful environment.</p>Damaged Wiring
<p>Captivity can damage the brain's complex circuitry, including the basal ganglia. This group of neurons communicates with the cerebral cortex along two networks: a direct pathway that enhances movement and behavior, and an indirect pathway that inhibits them.</p><p>The repetitive, <a href="http://dx.doi.org/10.1016/j.bbr.2014.05.057" target="_blank">stereotypic behaviors</a> that many animals adopt in captivity are caused by an imbalance of two neurotransmitters, dopamine and <a href="https://doi.org/10.1016/j.neubiorev.2010.02.004" target="_blank" rel="noopener noreferrer">serotonin</a>. This impairs the indirect pathway's ability to modulate movement, a condition documented in species from chickens, cows, sheep and horses to primates and big cats.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQ1MDQ0NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NTk4ODQ5MH0.y-zYv_gEQ-pgdSyytSGEq5Jq3uYWqYR24kKHuEhl7Qo/img.jpg?width=980" id="cf7b3" class="rm-shortcode" data-rm-shortcode-id="03ebc3885a895e0d497ec39dde96d295" data-rm-shortcode-name="rebelmouse-image" />

Reintroducing wolves is on the ballot in Colorado. Gunner Ries / Wikimedia Commons / CC by 3.0
By Tara Lohan
Maybe we can blame COVID-19 for making it hard to hit the streets and gather signatures to get initiatives on state ballots. But this year there are markedly fewer environmental issues up for vote than in 2018.
While the number of initiatives may be down, there's no less at stake. Voters will still have to make decisions about wildlife, renewable energy, oil companies and future elections.
Here's the rundown of what's happening where.
Return of an Apex Predator
<p>Wolves are on the ballot in Colorado. <a href="https://leg.colorado.gov/ballots/reintroduction-and-management-gray-wolves" target="_blank" rel="noopener noreferrer">Proposition 114</a> would require the state's Parks and Wildlife Commission to create a plan by 2023 for the reintroduction and management of gray wolves (<em>Canis lupus</em>) in areas west of the continental divide.</p><p>Gray wolves once roamed across the western United States but were mostly eradicated by the 1930s. Slowly efforts are being made to bring them back. The reintroduction of gray wolves to Yellowstone National Park in 1996 has been hailed as a <a href="https://www.theguardian.com/environment/2020/jan/25/yellowstone-wolf-project-25th-anniversary" target="_blank" rel="noopener noreferrer">rewilding success</a>.</p><p>"The argument is that by putting back in wolves — an apex predator that has evolved alongside their prey species — we're putting things back into ecological balance," University of Colorado Boulder ecology professor Joanna Lambert <a href="https://therevelator.org/wolf-reintroduction-colorado/" target="_blank">told <em>The Revelator</em></a> in a February interview about the science behind wolf reintroductions.</p><p>The Rocky Mountain Elk Foundation and the Colorado Farm Bureau are two of the top donors to the opposition groups.</p><p>The measure does include compensation for losses of livestock caused by gray wolves.</p><p>"What we're all hoping for is a landscape where we can coexist with the species that were originally here, but also acknowledging that humans need to make a living and that the costs of this initiative will be felt by some folks more than others," Lambert said.</p>Confusion Over Clean Energy
<p>In Nevada voters will take a second swing at a constitutional amendment to require that electric utilities source 50% of their electricity from renewables by 2030. Voters passed the same measure, <a href="https://www.nvsos.gov/sos/home/showdocument?id=8826" target="_blank">Question 6</a>, in 2018, but state law requires that constitutional amendments be passed in two consecutive even-numbered election years.</p><p>More clean energy for the state may seem good. But there's concern that enshrining 50% renewables by 2030 in the state's constitution isn't that ambitious and it will make it harder to continue the push for 100% renewables in the future. To do that would be another constitutional amendment that would again take four years and two consecutive ballot wins to move the needle.</p><p>Also, the state is already on its way to the same renewable goal.</p><p>A legislative effort to achieve 50% renewables by 2030 — but with a slightly different timeline for the increments to get there — was signed into law in April 2019 by Nevada Gov. Steve Sisolak. Renewable advocates hope the state will do even better than that benchmark, but passing Question 6 would make it harder.</p>Paying a Fair Share
<p>If California's <a href="https://www.sos.ca.gov/elections/ballot-measures/qualified-ballot-measures/" target="_blank">Proposition 15</a> passes, commercial and industrial properties will need to start paying taxes based on their current market value, instead of paying based on the purchase price from decades prior (which stems from Proposition 13 passed back in 1978). The initiative would exempt agricultural land, small businesses, renters and homeowners.</p><p>Reassessing the worth of large commercial properties could bring in between $7.5 billion and $12 billion a year that would go toward supporting local governments, school districts and community colleges.</p><p>Most of the <a href="https://ballotpedia.org/California_Proposition_15,_Tax_on_Commercial_and_Industrial_Properties_for_Education_and_Local_Government_Funding_Initiative_(2020)" target="_blank">opposition</a> has come from big business and anti-taxation groups.</p><p>The California Teachers Association Issues PAC is the biggest supporter of the effort, but a number of <a href="https://www.yes15.org/endorsers-environment" target="_blank" rel="noopener noreferrer">environmental groups</a> have also endorsed the measure, which would likely see oil companies and other big industrial polluters having to kick in more money.</p><p>"The oil industry has used Prop. 13 loopholes to evade tens of millions of dollars in property taxes," <a href="https://www.nrdc.org/experts/victoria-rome/nrdc-announces-support-californias-proposition-15" target="_blank" rel="noopener noreferrer">wrote Victoria Lome</a>, California legislative director for the Natural Resources Defense Council. "Companies like Chevron, Exxon, Phillips 66, Shell and Tosco are paying taxes based on assessments taken prior to 2000. Prop. 15 would end this hidden subsidy to dirty energy."</p><p>Oil companies could stand to lose in Alaska, too. Voters there will weigh in on <a href="https://ballotpedia.org/Alaska_Ballot_Measure_1,_North_Slope_Oil_Production_Tax_Increase_Initiative_(2020)" target="_blank" rel="noopener noreferrer">Ballot Measure 1</a>, which would increase taxes on big oil producers (those that have produced more than 400 million barrels overall or 40,000 barrels a day in the past year) operating in three established oil fields in the North Slope.</p>Taking the Wind Out of the Sails of the Electoral College
<p>Colorado's <a href="https://leg.colorado.gov/ballots/adopt-agreement-elect-us-president-national-popular-vote" target="_blank">Proposition 113</a> isn't about environmental issues directly but could cause big shifts in how presidential elections are run and what states and issues are considered important.</p><p>The initiative would add Colorado to the <a href="https://www.nationalpopularvote.com/written-explanation" target="_blank">National Popular Vote Interstate Compact</a>. That effort is aimed at ensuring the presidential candidate who wins the popular vote wins the election. It doesn't eliminate the Electoral College, but it saps its power.</p><p>The compact needs states representing at least 270 Electoral College votes to go into effect. It's currently at 196.</p><p>If Colorado's proposition is passed, and if the National Popular Vote Interstate Compact eventually gets enough votes to go into effect, then Colorado's nine electoral votes would go to the presidential candidate who wins the popular vote, not to the one who gets the most votes in Colorado.</p>From Your Site Articles

The World Health Organization, along with its global partners in the fight against the COVID-19 pandemic, has announced that it will provide 120 million rapid-diagnostic antigen tests to people in lower- and middle-income countries over the next six months. The tests represent a "massive increase" in testing worldwide, according to the Global Fund, a partnership that works to end epidemics.
<p>"We have an agreement, we have seed funding and now we need the full amount of funds to buy these tests," said WHO Director-General Tedros Adhanom Ghebreyesus on Monday, without providing further details. The program will initially require $600 million and is planned to start as early as October.</p><p>This mass testing campaign is part of a <a href="https://ec.europa.eu/commission/presscorner/detail/en/ip_20_710" target="_blank" rel="noopener noreferrer">global initiative launched in April</a> by the WHO, the European Commission, the Bill & Melinda Gates Foundation and the French government. Additional partner organizations include the Global Fund, the Africa Centers for Disease Control and Prevention, the Clinton Health Access Initiative, the Foundation for Innovative New Diagnostics (FIND) and Unitaid.</p><p>The test manufacturers, South Korea's SD BioSensor and U.S.-based Abbott Laboratories, have agreed to provide 20% of their test kits to lower- and middle-income countries. The remainder will be made available to wealthier nations, some of whom are helping to finance the test drive. Germany, for example, has already ordered some 20 million test kits.</p>
Quick Test Can Break Infection Chains
<p>"These tests provide reliable results in approximately 15 to 30 minutes, rather than hours or days, at a lower price with less sophisticated equipment," said WHO head Tedros, adding that the tests would cost as little as $5 each, and could become cheaper still. He said the rapid tests would help expand testing to hard-to-reach areas which aren't as well-equipped, or which are lacking trained health workers.</p><p>"High-quality rapid tests show us where the virus is hiding, which is key to quickly tracing and isolating contacts and breaking the chains of transmission," said Tedros. "The tests are a critical tool for governments as they look to reopen economies and ultimately save both lives and livelihoods."</p><p>Catharina Boehme, head of FIND, also welcomed the widespread rollout of cheap test kits. "This really shows what can be achieved when the world and leading global health partners come together with a common priority," she said.</p>How Do COVID-19 Antigen Tests Work?
<p>There are currently three different types of coronavirus diagnostic tests on the market: antigen tests, polymerase chain reaction (PCR) tests and serology tests (ELISA). </p><p>Rapid antigen tests target virus proteins, and somewhat resemble pregnancy tests. They aren't yet available at pharmacies and can only be administered by trained medical personnel. With a nasal or throat swab, testers can find out within approximately 15 minutes whether a patient has contracted the SARS-CoV-2 virus and is infectious and must be quarantined.</p><p>The advantage of rapid antigen tests is that they can be conducted quickly and on the spot. <br></p><p>It's hoped that this will help save the lives of thousands of people and slow the spread of the pandemic in the world's poorest countries. Rapid antigen tests can be used to carry out mass screenings among health care workers in low-income countries, who are at greater risk of death from COVID-19. These tests could also be used in schools, in the workplace and in nursing and retirement homes.</p><p>The major disadvantage of rapid antigen tests is that they're less reliable than PCR tests, which are conducted in labs and designed to detect the virus' genetic material. Rapid antigen tests may also be less effective in detecting infections in the early stages.</p><p>Still, a growing number of medical experts are backing the mass rollout of antigen tests, as they allow infected people to be identified even before they show symptoms, when individuals have a high viral load and are especially infectious.</p>Not All Rapid Test Kits Are Reliable
<p>Hundreds of rapid COVID-19 test kits have come on the market recently. Many of them are reliable, but not all. In March, for example, Spain sent back two batches of unlicensed Chinese test kits because they were flawed.</p><p>The European Center for Disease Prevention and Control has pointed out that even though many tests have been approved for sale on the European market, very few clinical studies show whether they are actually effective.</p><p>The 120 million test kits set to be rolled out by the WHO are the first to meet all of the organization's standards; test makers SD BioSensor and Abbott were granted emergency approval by the WHO last week.</p><p>The manufacturers claim their tests are up to 97% reliable in lab conditions; in the real world, the tests are said to be between 80% and 90% reliable. While this is good, it also means some 20% of patients will receive negative results despite being infected, which could lead to further spread of the virus.</p>What Are the Alternatives to Antigen Tests?
<p>Rapid antigen tests are ideal to test scores of patients quickly, simply and cheaply. Lab-based PCR tests, however, are superior in terms of reliability.</p><p>The PCR test detects genetic material, or RNA, from the SARS-CoV-2 virus. Patients are asked to provide a throat swab. One part of the person's genetic material is then synthesized, after which a biochemical process known as agarose gel electrophoresis is used to detect if the sample contains virus RNA. These tests are highly reliable but can only be conducted in specialized labs.</p><p>Serologic testing, on the other hand, detects antibodies in a person's blood that form when the immune system responds to a certain pathogen. This indicates that a person has already been exposed to the virus. While quick test kits are available for this method, these are mainly used for scientific studies.<br></p>

U.S. President Donald Trump and Democratic presidential nominee Joe Biden participate in the first presidential debate moderated by Fox News anchor Chris Wallace at the Health Education Campus of Case Western Reserve University on Sept. 29, 2020 in Cleveland, Ohio. Scott Olson / Getty Images
The first presidential debate seemed like it would end without a mention of the climate crisis when moderator Chris Wallace brought it up at the end of the night for a segment that lasted roughly 10 minutes.
<p>The raucous event in Cleveland, Ohio was notable for President Donald's Trump's constant interruptions and bullying behavior as he spoke over the Democratic nominee, Joe Biden, and Wallace. "Mr. Trump purposefully and repeatedly heckled and blurted over his rival and the moderator alike in a 90-minute melee that showcased the president's sense of urgency to upend a race," is how Shane Goldmacher of <a href="https://www.nytimes.com/2020/09/30/us/politics/presidential-debate-recap.html?action=click&module=Spotlight&pgtype=Homepage" target="_blank">The New York Times</a> summarized the night.</p><p>It was with that backdrop that Wallace said toward the end of the evening, "I'd like to talk about climate change." He then spoke about the forest fires in the West, turned toward Trump and noted that Trump said he doesn't believe that science knows if the climate crisis is triggering record-setting wildfires.</p>
<p>"Over your four years, you have pulled the U.S. out of the Paris climate accord," Wallace said. "You have rolled back a number of Obama environmental records. What do you believe about the science of climate change, and what will you do over the next four years to confront it?"</p><p>"I want crystal clean water and air, we now have the lowest carbon … if you look at our numbers now we are doing phenomenally," Trump said in response. He then insisted that people are people are very happy he has started to withdraw the U.S. out of the Paris climate accord before turning the discussion to how states in the West need to improve their forest management.</p><p>That distraction from the question pushed Wallace to interrupt Trump. "What do you believe about the science of climate change, sir?" And then later in the segment, he asked, "Do you believe that human pollution, greenhouse gas emissions, contribute to the global warming of the planet?"</p><p>Trump said he did, to an extent, and then pivoted again to forest management.</p>
<p>As Trump spoke of the need to better manage the forests, Biden looked bemused, often laughing at the president's answers and shaking his head.</p><p>"But sir, if you believe in the science of climate change, why have you rolled back the Obama Clean Power Plan, which limited carbon emissions in power plants? Why have you relaxed fuel economy standards that are going to create more pollution from cars and trucks?" Wallace asked.</p><p>Trump dismissed that idea, insisting that more new cars will be bought which will make them safer.</p><p>When Biden had a chance to speak about his $2 trillion green energy plan, the former vice president spoke about his track record in bringing down the cost of <a href="http://www.ecowatch.com/renewable-energy/" target="_self">renewable energy</a> and said that coal-fired and oil-fired power plants were going extinct in America.</p>
<p>He also spoke of replacing the federal automotive fleet of vehicles with electrical vehicles. He mentioned a plan to weatherize millions of buildings and homes to reduce the need for both heating and air conditioning. He then insisted the country could reach net-zero emissions in 15 years while creating millions of jobs to overhaul the country's energy infrastructure.</p><p>When Trump tried to tie Biden to the yoke of the Green New Deal and erroneously labeled the price tag at $100 trillion, Biden insisted that his plan was not the Green New Deal, but his own.</p><p>Discussing the costs, Biden pointed to the steep price tag of ecological disaster.</p><p>"We spend billions of dollars now, billions of dollars, on floods, hurricanes, rising seas," he said. "We're in real trouble."</p>
<p>The pivot toward the climate crisis was a surprise. Before the debate, Wallace, a Fox News host, had said the debate would focus on a handful of topics: the Supreme Court, the coronavirus pandemic, the economy, election integrity and "race and violence in our cities," according to <a href="https://www.washingtonpost.com/politics/2020/09/29/energy-202-climate-change-left-off-debate-list-even-though-polls-show-it-growing-concern-among-voters/" target="_blank">The Washington Post</a>.</p><p>The omission of the climate crisis was striking, as activists worried that debate moderators would ignore the number one issue today to young people, just as it was in the 2016 debates, according to The Washington Post.</p><p>The omission also raised the ire of Democratic lawmakers. Prior to the debate, 40 Democratic senators sent a letter to the debate commission insisting upon questions that address the climate crisis.</p><p>"Without these topics, any discussion on the economy, racial justice, public health, national security, democracy, or infrastructure would be incomplete," said the letter, as The Washington Post reported.</p>

Columbia Basin pygmy rabbits. Washington Department of Fish and Wildlife
The wildfires that roared through Eastern Washington in September had a devastating impact on an extremely endangered species of rabbit.
<p>The fast-moving Pearl Hill and Cold Springs fires scorched a habitat for Columbia Basin pygmy rabbits on Sept. 7, wiping out around half of the species' recovering population, <a href="https://www.hcn.org/articles/latest-endangered-pygmy-rabbit-population-halved-by-fast-moving-fire?fbclid=IwAR2pzH5M9FLQkGBEVPriSAyklH8Tej1B66EhCfPKYQbnAkSD9j3kEJT8chA" target="_blank">High Country News reported Monday</a>.</p><p>"The sun was blotted out, it was just red from the fire glare and the smoke and all you saw was rocks and sand and dust, there was just nothing," Washington Department of Fish and Wildlife (WDFW) Biologist Jon Gallie told <a href="https://www.wenatcheeworld.com/paywalloff/fire-wipes-out-half-of-columbia-basin-pygmy-rabbit-population/article_8c20b63c-f475-11ea-b668-83235dc86d8a.html" target="_blank">The Wenatchee World</a> after the fire. "I have not seen a sagebrush fire that hot in my 13 years out here."</p>
<p>Gallie leads a recovery program for North America's smallest rabbits, which are about the size of a grapefruit, according to High Country News. Their population was devastated during the 20th century by development, agriculture and wildfires and, in 2001, the last 16 were gathered from the wild for a captive breeding program. Scientists bred the Washington rabbits with pygmy rabbits from the Great Basin of the intermountain West and began to reintroduce them to the wild in 2011, according to The Wenatchee World.</p><p>To defend against wildfires, the rabbits were released in three different locations: Jameson Lake, Beezley Hills and Sagebrush Flats. It was the Jameson Lake population that was lost to September's flames.</p>

<p>"We have pygmy rabbits well distributed on the landscape in two other areas, so not all is lost," Gallie told High Country News. "We will just have to chart a now more challenging path to recovery."</p><p>However, WDFW manager of <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> diversity Hannah Anderson told <a href="https://www.seattletimes.com/seattle-news/environment/endangered-wildlife-habitat-burned-in-wildfires/" target="_blank" rel="noopener noreferrer">The Seattle Times</a> that the department had been focusing on the Jameson Lake population and had expected it to increase.</p><p>"It's devastating," Anderson said. "A catastrophic loss and a significant loss in recovery."</p>
<p>The rabbits aren't the only endangered species that were harmed by the fires. The Pearl Fire may also have reduced the state's sage grouse population by 30 to 70 percent, according to The Seattle Times.</p><p>The fires also damaged the sagebrush ecosystem these and other species depend upon. This unique, biodiverse shrub-steppe environment once covered 10.4 million acres of Washington state, but has declined by 80 percent since the mid-19th century. The fires wiped out thousands more acres within days.</p><p>While sagebrush ecosystems are used to fires, <a href="https://www.ecowatch.com/tag/invasive-species" target="_self">invasive species</a> of weeds have taken root that dry out early and encourage hotter, larger fires. It takes sagebrush steppe 10 to 20 years to recover from such blazes.</p><p>"Truly, now preserving what we have left is going to be the challenge," WDFW habitat program director Margen Carlson told The Seattle Times.</p>The <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a> is also <a href="https://www.ecowatch.com/wildfires-climate-fires-2647729127.html" target="_self">fueling</a> larger, more extreme fires in Washington and around the world.

By Mark Hertsgaard
What follows are not candidate endorsements. Rather, this nonpartisan guide aims to inform voters' choices, help journalists decide what races to follow, and explore what the 2020 elections could portend for climate action in the United States in 2021 and beyond.
Will the White House Turn Green?
<p>Whether the White House changes hands is the most important climate question of the 2020 elections. President Donald Trump rejects climate science, is withdrawing the United States from the Paris Agreement, and has accelerated fossil fuel development. His climate policy seems to be, as he tweeted in January when rejecting a U.S. Army Corps of Engineers proposal to protect New York City from storm surges, "Get your mops and buckets ready."</p><p>Joe Biden, who started the 2020 campaign with a climate position so weak that activists gave it an "F," called Trump a "climate arsonist" during California's recent wildfires. Biden backs a $2 trillion plan to create millions of jobs while slashing emissions—a Green New Deal in all but name. Equally striking, his running mate, California Senator Kamala Harris, has endorsed phasing out fossil fuel production—a politically explosive scientific imperative.</p><p>The race will be decided in a handful of battleground states, five of which already face grave climate dangers: Florida (hurricanes and sea-level rise), North Carolina (ditto), Texas (storms and drought), Michigan (floods), and Arizona (heat waves and drought). <a href="https://climatecommunication.yale.edu/visualizations-data/ycom-us/" target="_blank">Public concern is rising</a> in these states, but will that concern translate into votes?</p>Will Democrats Flip the Senate, and by Enough to Pass a Green New Deal?
<p>With Democrats all but certain to maintain their majority in the U.S. House of Representatives, the Senate will determine whether a potential Biden administration can actually deliver climate progress. Democrats need to pick up three seats to flip the Senate if Biden wins, four if he doesn't. But since aggressive climate policy is shunned by some Democrats, notably Joe Manchin of coal-dependent West Virginia, Democrats probably need to gain five or six Senate seats to pass a Green New Deal.</p><p>Environmentalists, including the League of Conservation Voters, are targeting six Republicans who polls suggest are vulnerable.</p><ul><li>Steve Daines of Montana, who denies climate science</li><li>Martha McSally of Arizona</li><li>Thom Tillis of North Carolina</li><li>Susan Collins of Maine</li><li>Joni Ernst of Iowa (bankrolled by Charles Koch)</li><li>John James of Michigan (also a Koch beneficiary)</li></ul><p>Republican Senators are even at risk in conservative Kansas and Alaska. In both states, the Democratic candidates are physicians—not a bad credential amid a pandemic—who support climate action. In Kansas, Barbara Bollier faces an incumbent funded by Charles Koch. In Alaska, Al Gross urges a transition away from oil, though his openness to limited drilling in the Arctic National Wildlife Preserve dims his appeal to green groups. He faces incumbent Republican Dan Sullivan, who receives an 8 percent lifetime voting record from the League of Conservation Voters.</p><p>In the House, environmentalists are working to elect these candidates, in one case over an establishment Democrat:</p><ul><li>Beth Doglio of Washington state</li><li>Georgette Gómez of California</li><li>Marie Newman of Illinois</li><li>Cameron Webb of Virginia</li><li>Mike Siegel and Wendy Davis of Texas</li></ul><p>We rightfully focus on federal climate policy, but climate action must also be made at the state and local level—and there are plenty of races and initiatives to pay attention to.</p>
Will Local and State Races Advance Climate Progress?
<h4>THE CLIMATE HAWKS</h4><p>Under Democratic and Republican leadership alike, Washington has long been a graveyard for strong climate action. But governors can boost or block renewable energy; the Vermont and New Hampshire races are worth watching. Attorneys general can sue fossil fuel companies for lying about climate change; climate hawks are running for the top law enforcement seats in Montana and North Carolina. State legislatures can accelerate or delay climate progress, as the new Democratic majorities in Virginia have shown. Here, races to watch include Pennsylvania, North Carolina, and Colorado.</p><h4>THE CLIMATE POLICY MAKERS</h4><p>Perhaps the most powerful, and most overlooked, climate policy makers are public utility commissions. They control whether pipelines and other energy infrastructure gets built; they regulate whether electric utilities expand solar and energy efficiency or stick with the carbon-heavy status quo. Regulatory capture and outright corruption are not uncommon.</p><p>A prime example is Arizona, where a former two-term commissioner known as the godfather of solar in the state is seeking a comeback. Bill Mundell argues that since Arizona law permits utilities to contribute to commissioners' electoral campaigns, the companies can buy their own regulators. Which may explain why super-sunny Arizona has so little installed solar capacity.</p><p>In South Dakota, Remi Bald Eagle, a Native American U.S. Army veteran, seeks a seat on the South Dakota Public Utilities Commission, which rules on the Standing Rock oil pipeline. And in what <em>HuffPost</em> called "the most important environmental race in the country," Democrat Chrysta Castaneda, who favors phasing out oil production, is running for the Texas Railroad Commission, which despite its name decides what oil, gas, and electric companies in America's leading petro-state can build.</p>Will the Influencers Usher in a Green New Era?
<h4>THE UNCOUNTED</h4><p>The story that goes largely under-reported in every U.S. election is how few Americans vote. In 2016, some 90 million, <a href="https://www.pewresearch.org/politics/2018/08/09/an-examination-of-the-2016-electorate-based-on-validated-voters/" target="_blank" rel="noopener noreferrer">roughly four out of every 10 eligible voters</a>, did not cast a ballot. Attorney Nathaniel Stinnett claims that 10 million of these nonvoters nevertheless identify as environmentalists: They support green policies, even donate to activist groups; they just don't vote. Stinnett's <a href="https://www.environmentalvoter.org/" target="_blank" rel="noopener noreferrer">Environmental Voter Project</a> works to awaken this sleeping giant.</p><h4>THE SUNRISE MOVEMENT</h4><p>Meanwhile, the young climate activists of the <a href="http://www.sunrisemovement.org/" target="_blank" rel="noopener noreferrer">Sunrise Movement</a> are already winning elections with an unabashedly Green New Deal message. More than any other group, Sunrise pushed the Green New Deal into the national political conversation, helping Representative Alexandria Ocasio-Cortez and Senator Ed Markey draft the eponymous congressional resolution. In 2020, Sunrise has helped Green New Deal champions defeat centrists in Democratic primaries, with Markey dealing Representative Joe Kennedy Jr. the first defeat a Kennedy has ever suffered in a Massachusetts election. But can Sunrise also be successful against Republicans in the general elections this fall?</p><h4>THE STARPOWER</h4><p>And an intriguing wild card: celebrity firepower, grassroots activism, and big-bucks marketing have converged behind a campaign to get Latina mothers to vote climate in 2020. Latinos have long been the U.S. demographic most concerned about climate change. Now, <a href="https://votelikeamadre.com/" target="_blank" rel="noopener noreferrer">Vote Like A Madre</a> aims to get 5 million Latina mothers in Florida, Texas, and Arizona to the polls. Jennifer Lopez, Salma Hayak, and Lin-Manuel Miranda are urging mothers to make a "pinky promise" to vote for their kids' climate future in November. Turning out even a quarter of those 5 million voters, though no easy task, could swing the results in three states Trump must win to remain president, which brings us back to the first category, "Will the White House Turn Green?"</p>From Your Site Articles

The wildfires that ignited in the Arctic this year started earlier and emitted more carbon dioxide than ever before.
<p>Now, a group of researchers is warning that the nature of Arctic fires may be changing, and it's important to understand how in order to better predict the future of the global <a href="https://www.ecowatch.com/climate-change/" target="_self">climate</a>.</p><p>"It's not just the amount of burned area that is alarming," University of Colorado Boulder fire and <a href="https://www.ecowatch.com/tag/permafrost" target="_self">permafrost</a> ecologist Dr. Merritt Turetsky said in a press release <a href="https://phys.org/news/2020-09-arctic.html?fbclid=IwAR3y_vHkipR0x6-jCOdOYoVJYSHmqigeMnzhjBIQxV_-2GUnFbA4pfiMzzE" target="_blank">published by Phys.org</a>. "There are other trends we noticed in the satellite data that tell us how the Arctic fire regime is changing and what this spells for our climate future."</p><p>Turetsky co-wrote a commentary in <a href="https://www.nature.com/articles/s41561-020-00645-5" rel="noopener noreferrer" target="_blank"><em>Nature Geoscience</em></a> Monday with two other fire experts. The <a href="https://www.ecowatch.com/tag/scientists" target="_self">scientists</a> pinpointed two important ways that Arctic wildfires are changing.</p>
<h3>1. Zombie Fires</h3><p><a href="https://www.ecowatch.com/zombie-fires-arctic-2646140786.html" target="_self">Zombie fires</a>, also known as holdover fires, occur when fires from the previous season continue to burn beneath the ground during the winter. These blazes can then reemerge when the snow melts and the weather warms.</p><p>Satellite monitoring data from the <a href="https://atmosphere.copernicus.eu/copernicus-tracks-effects-arctic-circle-wildfires" rel="noopener noreferrer" target="_blank">Copernicus Atmosphere Monitoring Service</a> confirmed that zombie fires helped drive 2020's unprecedented wildfire season, which broke records both for the number of blazes and the amount of carbon released into the atmosphere, as <a href="https://www.livescience.com/zombie-wildfires-burn-arctic.html" rel="noopener noreferrer" target="_blank">Live Science reported</a>. But the scientists writing in Nature Geoscience say they still need to learn more about these unusual fires and how they may contribute to climate feedback loops.</p><p>"We know little about the consequences of holdover fires in the Arctic," Turetsky said in the press release, "except that they represent momentum in the climate system and can mean that severe fires in one year set the stage for more burning the next summer."</p><p>Indeed, the 2020 wildfire season broke records that had been set just the year before, in <a href="https://www.ecowatch.com/arctic-wildfires--2639340124.html" target="_self">2019's also unprecedented season</a>.</p>
<h3>2. Fires Where Fire Shouldn't Be</h3><p>The other troubling feature of the 2019 and 2020 Arctic wildfire seasons is that their blazes ignited in areas typically resistant to burning, the scientists pointed out. This included tundra vegetation such as dwarf shrubs, sedges, grasses and mosses and previously burn-free environments like bogs, fens and marshes.</p><p>Significantly, more than 50 percent of the 2020 fires burning above 65° North occurred on ice-rich permafrost, which contains the most carbon of any Arctic soil.</p><p>"Nearly all of this year's fires inside the Arctic Circle have occurred on continuous permafrost, with over half of these burning on ancient carbon-rich peat soils," commentary coauthor and London School of Economics and Political Science fire scientist Dr. Thomas Smith said in the press release. "The record high temperatures and associated fires have the potential to turn this important carbon sink into a carbon source, driving further global heating."</p><p>The scientists called for more research into the dynamics of Arctic fires to better understand how they will contribute to the climate crisis. Part of this requires collaborating with local and <a href="https://www.ecowatch.com/tag/indigenous" target="_self">Indigenous</a> communities, who can provide on-the-ground observations to accompany satellite data.</p><p>"The burning Arctic is a global issue that requires a global solution," the scientists concluded. "While the expertise of the Indigenous communities of the North and Arctic nations will be central to any success, we cannot expect them to shoulder the responsibility alone."</p>

A metapopulation project in South Africa has almost doubled the population of cheetahs in less than nine years. Ken Blum / Wikimedia Commons / CC by 3.0
By Tony Carnie
South Africa is home to around 1,300 of the world's roughly 7,100 remaining cheetahs. It's also the only country in the world with significant cheetah population growth, thanks largely to a nongovernmental conservation project that depends on careful and intensive human management of small, fenced-in cheetah populations. Because most of the reserves are privately funded and properly fenced, the animals benefit from higher levels of security than in the increasingly thinly funded state reserves.
<p>Initiated by the Endangered Wildlife Trust nearly a decade ago, the Cheetah Metapopulation Project recognizes that small cheetah populations may be physically secure in several small reserves, but the likelihood of inbreeding remains high if they are kept separated behind fences. By swapping animals between participating reserves, the trust helps private and state wildlife custodians manage overpopulation and underpopulation on their land and also identify new areas of suitable cheetah habitat. Most importantly, swapping animals reduces the risk of inbreeding among closely related animals.</p><p>Vincent van der Merwe, coordinator of the trust's metapopulation initiative, says that when the project began in 2011, there were 217 cheetahs scattered between 41 reserves. Now there are 419 spread across 60 reserves — more than a third of South Africa's total cheetah population.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQ0Njk3OC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYwODQ5MTUxN30.-OSR8R8p9Ub3eyrwOEdltu7P4nnXAFwNlwekJVJz50I/img.jpg?width=980" id="4f7f7" class="rm-shortcode" data-rm-shortcode-id="513e5803db97d5d6c8ea489d509274b3" data-rm-shortcode-name="rebelmouse-image" />

Under Pressure
<p>Cheetah populations elsewhere in Southern Africa have not prospered over the past 50 years. In Zimbabwe, cheetah numbers have crashed from 1,500 in 1975, to just 170 today. Botswana's cheetah population has held steady at around 1,500 over the same period, but illegal capture for captive breeding and conflicts with farmers and the growing human population are increasing. In Namibia, there were an estimated 3,000 cheetah in in 1975; roughly 1,400 remain today.</p><p>In contrast, South Africa's cheetah numbers have grown from about 500 in 1975 to nearly 1,300 today. Van der Merwe, who is also a Ph.D. student at the University of Cape Town's Institute for Communities and Wildlife in Africa (iCWild), says he's confident that South Africa will soon overtake Namibia and Botswana, largely because the majority of South African cheetahs are protected and managed behind fences, whereas most of the animals in the neighboring countries remain more vulnerable on mainly unfenced lands.</p><p>Wildlife researchers Florian Weise and colleagues have reported that private stock owners in Namibia still trap cheetahs mainly for translocation, but there are few public or private reserves large enough to contain them. Weise says that conservation efforts need to focus on improving tolerance toward cheetahs in commercial livestock and game farming areas to reduce indiscriminate trapping.</p><p>Van der Merwe says fences can be both a blessing and a curse. While these barriers prevent cheetahs and other wild animals from migrating naturally to breed and feed, they also protect cheetahs from the growing tide of threats from humanity and agriculture.</p><p>To simulate natural dispersion patterns that guard against inbreeding, the trust helps landowners swap their animals with other cheetah reserves elsewhere in the country. The South African metapopulation project has been so successful in boosting numbers that the trust is having to look beyond national boundaries to secure new translocation areas in Malawi, Zambia and Mozambique.</p><p>Cheetah translocations have been going on in South Africa since the mid-1960s, when the first unsuccessful attempts were made to move scores of these animals from Namibia. These relocations were mostly unsuccessful.</p><p>"Most of those early attempts were a flop because the cheetahs were not kept in bomas before release and some of the reserves were also poorly fenced — so the cats shot out almost as soon as they were released," van der Merwe said.</p><p>Translocated cheetahs are now generally confined to capture bomas, small fenced enclosures, for four to six weeks to allow them to acclimate to their new home environment prior to being set free.</p><p>"We have found that four weeks is normally long enough to break the homing instinct and if you keep them in a boma for longer than that, they tend to lose fitness and condition," van der Merwe said.</p><p>The Phinda private game reserve in Zululand, one of several private game reserves that began re-introducing cheetahs in the early 1990s, recently swapped some of its animals with the nearby Manyoni private game reserve.</p><p>"We have found that when we capture and translocate cheetahs to other reserves, the Phinda cats do very well elsewhere because they grew up in a challenging environment," van der Merwe said. "Because they have to share space with lion, hyena and leopard they have learned to look after themselves — so they are pretty tough animals."</p>
<p>Charli de Vos, a wildlife monitor at Phinda, says when new cheetahs are released into the reserve in small units, at least one animal is fitted with a VHF tracking collar.</p><p>For the first few weeks, she says, the animals' movements are tracked on a daily basis to ensure that they are not showing "homing" tendencies and that they are also getting used to the presence of tourist and staff vehicles.</p><p>"This will apply until the animals have relaxed within their new environment. Once the animals have established a home range within the reserve (approximately three months after release), the VHF collar will be removed. Thereafter the research and monitoring team will try and get a visual of each individual cheetah at least once every second week," de Vos said.</p><p>The reserve also has an online database to record sightings of the animals, with tourist guides, researchers, land managers and land owners able to add sightings.</p><p>Despite a cub mortality rate of between 50% and 80% on some reserves, van der Merwe says there are now about 90 cheetahs in the Zululand area. He says cub mortality rates vary according to the number of larger predators such as lions and hyenas.</p>

<p>But other wildlife conservation leaders have a different perspective on cheetah conservation strategy.</p><p>Gus Mills, a senior carnivore researcher retired in 2006 from SANParks, the agency that manages South Africa's national parks, after a career of more than 30 years in Kalahari and Kruger national parks. He says the focus should be on quality of living spaces rather than the quantity of cheetahs.</p><p>Mills, who was the founder of the Endangered Wildlife Trust's Carnivore Conservation Group in 1995, and who also spent six years after retirement studying cheetahs in the Kalahari, says it's more important to properly protect and, where possible, expand the size of existing protected areas.</p><p>He also advocates a triage approach to cheetah conservation, in which scarce funds and resources are focused on protecting cheetahs in formally protected areas, rather than diluting scarce resources in an attempt to try and save every single remaining cheetah population.</p><p>"People have an obsession with numbers. But I believe that it is more important to protect large landscape and habitats properly," Mills said.</p><p>He suggests that cheetahs enclosed within small reserves live in artificial conditions: "It's almost like glorified farming."</p><p>"In the long run we have to focus on consolidating formally protected areas," he added. "Africa's human population will double by 2050, so cheetah populations in unfenced areas will become unsustainable if they are eating people's livestock."</p><p>Mills, who was closely involved in a similar metapopulation project for wild dogs, said he tried to encourage landowners to pull down the boundary fences, to create larger areas of habitat.</p><p>"But there are many landowners who don't want to do that. They want their own areas and their own management programs. But my philosophy is: Take care of the ecosystem so that the animals can take care of themselves, so that nature can run its course," Mills said.</p><p>"Unfortunately, there are so few areas left where nature can have its say these days."</p><p>Van der Merwe says the financial costs of metapopulation management are unavoidable and justified, noting that private reserves bear the overwhelming bulk of the translocation and monitoring costs.</p><p>"This is 2020. State funding for conservation has collapsed in most parts of Africa and the days of setting aside any new large, wild open spaces are long gone," he said. "We should be celebrating the fact that many more private ecotourism reserves have been established on former cattle ranches in South Africa, outcompeting agriculture as a land use and creating new habitat for cheetah. The best we can do is to try and consolidate smaller private and community-owned reserves with larger national parks."</p><p>Sarah M. Durant of the Zoological Society of London and the Wildlife Conservation Society, New York, says cheetahs remain susceptible to rapid decline and that, ultimately, conserving the remaining free-ranging populations in Botswana and Namibia will require "a paradigm shift in conservation toward a holistic approach that incentivizes protection and promotes sustainable human-wildlife coexistence across large multiple-use landscapes."</p>
