A searing heat wave has begun to spread across Europe, with Germany, France and Belgium experiencing extreme temperatures that are set to continue in the coming days.
In Germany, temperatures are expected to exceed 40 degrees Celsius (104 degrees Fahrenheit) on Wednesday, topping the country's previous June record of 38.2 degrees Celsius, set in Frankfurt in 1947. Temperatures in Bonn on Tuesday afternoon reached 35 degrees Celsius.
Firefighters Braced for Busy Week
Climate researcher Andreas Marx has said that the lack of rain in much of the country, particularly in the north and east, the site of much of Germany's agriculture, could have disastrous consequences.
Forest fires are of particular concern for authorities in Germany, especially in the northeast. Local residents were asked to keep windows and doors closed in Lieberoser Heide — southeast of Berlin — while emergency services deal with a fire that broke out on Monday and spread to an area of about 10 hectares (25 acres), the size of 140 soccer pitches. It is expected to take a few days to put out.
Temperatures exceeded 30 degrees Celsius in Frankfurt on Monday.

'We Must Be Vigilant': Macron
Meanwhile, French national weather agency Meteo-France predicted that the hot weather could produce temperatures of up to 40 degrees Celsius, while German agencies suggested the heat may break records.
"It's unprecedented because it's hitting so early, in June. We haven't seen this since 1947," said Emmanuel Demael from the French meteorological agency on Monday.

French President Emmanuel Macron has urged people to be extra vigilant in the coming days.
"As you know, at times like these, sick people, pregnant women, infants and elderly people are the most vulnerable. So we must be vigilant with them and have prevention measures in place in order to intervene as quickly as possible," he said.
His call was repeated by the International Federation of Red Cross and Red Crescent Societies in Geneva: "Our message this week is simple: look after yourself, your family and your neighbors. A phone call or a knock on the door could save a life."
In 2003 an estimated 70,000 people died in Europe during a heatwave.
Heat Waves on the Increase
Scientists say heat waves of this magnitude are on the increase in Europe, further evidence that the Earth's climate is changing due to the burning of fossil fuels.
Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research said "monthly heat records all over the globe occur five times as often today as they would in a stable climate."
"This increase in heat extremes is just as is predicted by climate science as a consequence of global warming caused by the increasing greenhouse gases from burning coal, oil and gas," he added.
Children Sent Home
In many countries, children were dismissed from class early or allowed to skip it entirely.
In France, final exams for students were delayed a week due to the heatwave.
Meanwhile, zoo animals across the continent were treated to special treats such as fruit icicles, buckets of water and swimming pools.

A new species of bat has been identified in West Africa. MYOTIS NIMBAENSIS / BAT CONSERVATION INTERNATIONAL
In 2018, a team of researchers went to West Africa's Nimba Mountains in search of one critically endangered species of bat. Along the way, they ended up discovering another.
<p>The new bat species, <em>Myotis nimbaensis</em>, has an unusual orange and black coloring, and it was written up for the first time last Wednesday in <a href="http://digitallibrary.amnh.org/handle/2246/7249" rel="noopener noreferrer" target="_blank"><em>American Museum Novitates</em></a>.</p><p>"In an age of extinction, a discovery like this offers a glimmer of hope," study coauthor and chief scientist at <a href="https://www.batcon.org/" target="_blank">Bat Conservation International</a> Winifred Frick told the <a href="https://www.amnh.org/about/press-center/bat-discovered-west-africa" target="_blank">American Museum of Natural History</a>. "It's a spectacular animal."</p>
<div id="78d2c" class="rm-shortcode" data-rm-shortcode-id="a6760c89eda21e1221babaa9939e75d3"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1349452120433553412" data-partner="rebelmouse"><div style="margin:1em 0">🚨 New research alert!

<p>Frick was part of a team of scientists from Bat Conservation International and the University of Maroua in Cameroon who were investigating natural caves and mining shafts in Guinea's Nimba Mountains. The mountains, which rise about one mile above sea level, are known as sky islands and are important <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> hotspots for species including bats.</p><p>One especially important bat species is the Lamotte's roundleaf bat, or <em>Hipposideros lamottei</em>, which lives only in the Nimba Mountains, and especially in abandoned mineshafts known as adits. But while trapping for the existing species, the scientists found something they did not expect.</p><p>"I looked in a net and there was just something interesting in there," Jon Flanders, director of endangered species intervention at Bat Conservation International, told <a href="https://www.washingtonpost.com/climate-environment/2021/01/13/new-orange-bat/?utm_medium=social&utm_campaign=wp_main&utm_source=twitter" target="_blank">The Washington Post</a>.</p>
<p>Flanders said he first saw the bat with his colleague Eric Moïse Bakwo Fils from the University of Maroua.</p><p>"Eric and I got back to camp and we independently started trying to figure out what the hell was going on. Finding a new species of specially colored bats is very rare. I was like, 'I'm pretty sure this is a new species'. We walked in the room in the morning and simultaneously said 'I think we've got a new species.' "</p><p>So the pair called up bat expert and American Museum of Natural History Curator Nancy Simmons for help.</p><p>"As soon as I looked at it, I agreed that it was something new," Simmons, who is also the paper's lead author, said in the museum press release.</p><p>Simmons confirmed her initial opinion with help from the Smithsonian and the British Museum of Natural History, she told The Washington Post.</p>
<div id="95b3b" class="rm-shortcode" data-rm-shortcode-id="bc43d84ce3edd0fa256e60e667833727"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1349785874356195330" data-partner="rebelmouse"><div style="margin:1em 0">Newly discovered bat has already won 2021 Halloween #Bat #Nature #Science #Wildlife https://t.co/WE1Qt1TE73</div> — Cool Science Videos (@Cool Science Videos)<a href="https://twitter.com/GeoBeats/statuses/1349785874356195330">1610649004.0</a></blockquote></div>
<p>There are more than 1,400 species of bats, and more than 20 new ones are added to the list every year, according to <a href="https://www.nytimes.com/2021/01/13/science/new-bat-species.html?auth=login-google" target="_blank">The New York Times</a>. But mostly, these discoveries are made in the lab by closely analyzing the DNA of similar-looking species previously thought to be the same.</p><p>"This sort of situation where experienced researchers went out in the field and caught an animal and held it in their hand and went, 'This is something we can't identify,' that's much more unusual," Simmons told The New York Times.</p><p>The new bat is likely already endangered, since it is only known to live in the Nimba Mountains. Researchers said the next step is to learn more about the species so that they can protect it more effectively.</p><p>Bakwo Fils also told The New York Times that he hoped the discovery would boost bat <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> in West Africa more generally. Bats are important pollinators, seed spreaders and pest eaters in the region, but superstition and their connection with Ebola has meant they are often harmed.</p><p>"This discovery is very important in terms of West Africa's bat biodiversity, because even if bats are a very important component of our ecosystems, they rarely receive attention," Bakwo Fils said.</p>

President-elect Joe Biden is planning to cancel the controversial Keystone XL pipeline on the first day of his administration, a document reported by CBC on Sunday suggests.
<p>The words "Rescind Keystone XL pipeline permit" were reportedly listed on a briefing note shared by the Biden transition team with U.S. stakeholders as part of a roundup of Biden's planned day one executive actions. <a href="https://www.ctvnews.ca/world/america-votes/biden-to-prioritize-blocking-of-keystone-xl-pipeline-extension-1.5270600" target="_blank">CTV News</a> also reviewed the briefing documents, and a source familiar with Biden's thinking told <a href="https://www.reuters.com/article/us-usa-biden-keystone/biden-to-cancel-keystone-xl-pipeline-permit-on-first-day-in-office-cbc-idINKBN29N00A" target="_blank">Reuters</a> that the President-elect is planning to cancel the pipeline as one of his first acts.</p><p>"The Biden administration halting the Keystone XL pipeline is a momentous sign that he is listening, taking action and making good on his promises to people and the planet," Kendall Mackey, 350.org Keep It In the Ground campaign manager, <a href="https://350.org/press-release/biden-kxl-executiveorder/" target="_blank">said</a> in response to the news. "This decision to halt the Keystone XL pipeline on day one in office sets a precedent that all permitting decisions must pass a <a href="https://www.ecowatch.com/climate-change/" target="_self">climate</a> test and respect <a href="https://www.ecowatch.com/tag/indigenous-rights" target="_self">Indigenous rights</a>."</p><p>Mackey expressed hope that Biden would also end the equally controversial <a href="https://www.ecowatch.com/tag/dakota-access-pipeline" target="_self">Dakota Access</a> and <a href="https://www.ecowatch.com/tag/enbridge-line-3" target="_self">Line 3</a> pipelines.</p><p>The Keystone XL pipeline was first announced in 2005, CBC News reported. The pipeline is being built to carry 830,000 barrels of crude oil a day, stretching about 1,200 miles from Alberta, Canada to Nebraska. From there it would connect with the original Keystone pipeline that carries oil to U.S. Gulf Coast refineries.</p>
<p>The pipeline has long been opposed by environmental and Indigenous groups, who are concerned about its climate impacts and the potential for leaks to harm <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> and pollute <a href="https://www.ecowatch.com/tag/drinking-water" target="_self">drinking water</a>, CTV News reported. Protests prompted the Obama administration to <a href="https://www.ecowatch.com/breaking-president-obama-rejects-keystone-xl-pipeline-1882117930.html" target="_self">rescind the permit in 2015</a>, but President Donald Trump reversed this decision with an <a href="https://www.ecowatch.com/trump-dakota-access-pipeline-2211697835.html" target="_self">executive order</a> in early 2017.</p><p>Biden's decision to once again rescind the permit is not surprising. His advisers have said in the past that he would move to block it again, according to <a href="https://www.huffpost.com/entry/biden-keystone-xl-pipeline-permit_n_60051931c5b6efae62f9d263" target="_blank">HuffPost</a>. Biden's campaign has vocally opposed the pipeline since May, according to CTV News.</p><p>The news has sparked opposition in Canada.</p><p>"I am deeply concerned by reports that the incoming administration of President-elect Joe Biden may repeal the Presidential permit for the Keystone XL border crossing next week," Alberta Premier Jason Kenney said in a Twitter <a href="https://twitter.com/jkenney/status/1350957580106006533/photo/1" rel="noopener noreferrer" target="_blank">statement</a>. "Doing so would kill jobs on both sides of the border, weaken the critically important Canada-U.S. relationship and undermine U.S. national security by making the United States more dependent on OPEC oil imports in the future."</p>
<p>Kirsten Hillman, Canada's ambassador to the U.S., said the country still stood behind the pipeline and that it fit within Canada's climate plans, CBC News reported.</p><p>"The Government of Canada continues to support the Keystone XL project and the benefits that it will bring to both Canada and the United States," Hillman said.</p><p>Meanwhile, in a bid to make the project more appealing to Biden, owner TC Energy announced a plan on Sunday to reach zero emissions by 2030, hire union workers, sign Indigenous equity partners and install a $1.7 billion solar, wind and battery-powered operating system for the pipeline.</p><p>However, Canadian environmental groups and parties were pleased with the news.</p>
<p>"This is what true climate leadership looks like," Annamie Paul, leader of the federal Green Party, told CTV News.</p><p>Keith Stewart, a senior energy strategist with Greenpeace Canada, urged Canadians to follow suit and move away from the pipeline, which he likened to "beating [a] dead horse," CBC News reported.</p><p>"The Biden administration offers us a fresh start on addressing the climate crisis with a willing partner, so let's not blow it by pushing pipelines," Stewart said.</p>

Seabirds often follow fishing vessels to find easy meals. Alexander Petrov / TASS via Getty Images
By Jim Palardy
As 2021 dawns, people, ecosystems, and wildlife worldwide are facing a panoply of environmental issues. In an effort to help experts and policymakers determine where they might focus research, a panel of 25 scientists and practitioners — including me — from around the globe held discussions in the fall to identify emerging issues that deserve increased attention.
<p>The panel, coordinated by the UK-based Cambridge Conservation Initiative, conducted a horizon scan — an effort to spot early signs of significant phenomena — of global biological <a href="https://www.ecowatch.com/tag/conservation">conservation</a> issues. For <a href="https://www.cell.com/trends/ecology-evolution/fulltext/S0169-5347(20)30306-2?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0169534720303062%3Fshowall%3Dtrue" target="_blank" rel="noopener noreferrer">the resulting study</a>, which was funded by the UK's Natural Environment Research Council and the Royal Society for the Protection of Birds, the panel winnowed down an initial list of 97 topics, settling on the following 15 because of their novelty or their potential to move the conservation needle in either a positive or negative direction over the coming decade.</p>
<h2>1. Seabirds Could Help Spot Illegal Fishing</h2><p>Seabirds often follow fishing vessels to score easy meals. Now, scientists are hoping to exploit this behavior to help spot illegal, unregulated, and unreported fishing, which accounts for up to $23.5 billion worth of seafood every year, or 1 in 5 fish sold. Researchers have had some success attaching transmitters to seabirds to locate fishing vessels in the Indian Ocean, but more study is needed to validate the use of this tactic.</p>
<h2>2. Marine Vessels and GPS Spoofing</h2><p>Vessels plying the ocean navigate and transmit their locations and identities mainly through the global navigation satellite system (GNSS) and automatic identification system (AIS). The panel points out that a recent rise in GNSS spoofing and AIS cloning incidents could facilitate the trade of illegal goods and hamper authorities' efforts to identify vessels engaged in illicit resource extraction activities such as fishing and dredging.</p>
<h2>3. More Corals May Suffer From Lack of Oxygen<br></h2><p>Several factors — including climate-driven marine heat waves and nutrient runoff from land — can lower oxygen levels in the ocean. Corals in the Atlantic, Indian, and Pacific oceans have died from this hypoxia, and, although those events weren't widespread, some scientists fear that the threat may grow significantly as climate change further warms the ocean. Research is needed to better understand the extent and impact of low oxygen conditions on coral reefs.</p>
<h2>4. Understanding the Impacts of Increased Dissolved Iron on Coastal Polar Ecosystems</h2><p>Coastal zones in polar latitudes are among Earth's most productive — that is, they create and support large numbers of organisms ranging from tiny marine plants to animals such as polar bears and seals — a characteristic driven by the availability of dissolved iron from glaciers and ice. Increased melting in the polar regions will result in higher iron concentrations, which in turn will probably fuel more intense phytoplankton blooms and enable organisms on the seafloor to capture more carbon and other nutrients. Such changes could have wide-ranging effects — including impacts on the structure of the region's marine ecosystems and on carbon sequestration — and warrants investigation.</p>
<h2>5. What to Do With a Growing Number of Decommissioned Offshore Energy Platforms</h2><p>It is estimated that 3,000 offshore oil and gas platforms will be decommissioned in the coming decades and that the number of offshore wind farms will continue to grow. Currently, decommissioning practices vary by country and include full removal, conversion of platforms to artificial reefs, and abandonment. As new offshore energy infrastructure is built and old platforms are phased out, nations will need to evaluate the immediate and long-term impacts of their decommissioning strategies on the marine environment.</p>
<h2>6. A Drug Problem in the Water<br></h2><p>When some chemicals used in pharmaceuticals and in garden and farm products are introduced into waterways — usually through runoff or via sewage systems directly or in human waste — they can cause changes in fish and other organisms, including altering the number of female to males in a population, lower fertility, and deformities. There is emerging evidence that the effects of exposure can be multigenerational, affecting organisms that were never directly exposed.</p>
<h2>7. Changes in Low Cloud Cover</h2><p>Low clouds shade sizable portions of the planet in subtropical regions. It is predicted that these clouds will become increasingly unstable if atmospheric carbon dioxide continues to rise at current rates. The resulting changes could have negative effects on wildlife and human communities.</p>
<h2>8. Tree Planting as a Simple Carbon Sequestration Solution</h2><p>Pledges to plant large areas of trees to help tackle climate change are often perceived as a win for conservation. However, tree planting must be planned and implemented with a clear understanding of regional ecosystems to avoid negative effects on biological diversity.</p>
<h2>9. Logging to Reduce Fire Risk</h2><p>As nations around the world contend with more extreme wildfires, some policymakers suggest that tree removal may be part of the solution. However, the effectiveness of such policies is uncertain, and any short-term gains from removing trees are often offset by the growth of non-native grasses and flowering plants, which may themselves be highly flammable.</p>
<h2>10. Large-Scale Adoption of Sustainable Farming Techniques Across India</h2><p>Driven by government policies and local innovations, sustainable farming practices are becoming more prevalent in India. The state government of Sikkim has adopted organic farming as policy, and the state of Andhra Pradesh, with 6 million farmers, plans to adopt natural farming practices by 2025. Other states across the country plan to follow suit. Early evaluations indicate that these large-scale transitions boost crop yields and incomes, improve the health of farmers, and increase women's access to microfinance. With such results, there is the potential for similar large-scale shifts in other parts of the world.</p>
<h2>11. Low Earth-Orbiting Satellites May Mislead Animals Responding to Celestial Cues</h2><p>More than 2,600 artificial satellites currently orbit the earth, a number that is rapidly increasing. Many species of mammals, insects, and birds use celestial cues to migrate long distances and to orient themselves in local habitats and could be affected by the proliferation of satellites.</p>
<h2>12. Bitcoin Mining With Stranded Energy</h2><p>An emerging use for stranded energy sources, such as low-value methane byproducts vented from oil wells and excess energy produced by wind turbines and solar panels, is to power computers used for Bitcoin mining — the process of creating new Bitcoin by solving complex algorithms. Monetizing stranded energy in this way is a mixed bag that decision-makers will probably have to evaluate. The practice could increase carbon emissions from marginal fossil fuel sources but also could incentivize the deployment of renewable energy by guaranteeing a minimum selling price.</p>
<h2>13. Open-Source Investigations of Environmental Threats</h2><p>Scientists demonstrated some success with using online videos, social media posts, and other open-source data to document the effects of the locust swarms in East Africa in 2020. As faster internet connections and access to smartphones continue to grow globally, the use of open-source data may become an effective tool for researchers.</p>
<h2>14. Self-Healing Building Materials</h2><p>The potential to engineer building materials made of chemicals, polymers, and bacteria that can fix themselves when damaged could reduce the need for repairs and shrink the environmental footprints of construction projects. Recently, scientists at the University of Colorado at Boulder used a type of cyanobacteria found in the ocean, along with other materials, to <a href="https://www.cell.com/matter/pdfExtended/S2590-2385(19)30391-1" target="_blank" rel="noopener noreferrer">engineer a living building material</a> that can regenerate when fractured.</p>
<h2>15. A Waterway to Connect the Baltic and Black Seas</h2><p>A planned 1,200-mile inland navigable waterway connecting the Baltic and Black seas would alter the flow of cargo and trade in the region. However, the waterway, which would pass through Poland, Belarus, and Ukraine, could alter habitat in 70 wildlife areas and numerous international conservation areas, introduce non-native species, and change the region's rivers and wetlands. Additionally, dredging in the Chernobyl Exclusion Zone could disrupt radioactive sediment.</p>

Ask a Scientist: What Should the Biden Administration and Congress Do to Address the Climate Crisis?

By Elliott Negin
What a difference an election makes. Thanks to the Biden-Harris victory in November, the next administration is poised to make a 180-degree turn to again address the climate crisis.
<p>President Trump famously called climate change a "hoax," appointed <a href="https://www.nytimes.com/interactive/2020/01/14/climate/fossil-fuel-industry-environmental-policy.html" target="_blank">fossil fuel industry lobbyists</a> to key positions in his administration, rolled back the Obama-era rule that would have curbed power plant carbon emissions, and weakened Obama-era limits on vehicle carbon emissions. Just a day after last fall's election, he pulled the United States out of the international Paris climate agreement.</p><p>By contrast, President-elect Biden has endorsed a $2 trillion climate plan, and pledged to issue at least <a href="https://s2.washingtonpost.com/2da6eed/5fdb55659d2fda0efb8b5293/596c46649bbc0f208657f096/11/67/5fdb55659d2fda0efb8b5293" target="_blank">10 executive orders</a> to protect the climate and rejoin the <a href="https://twitter.com/JoeBiden/status/1340427943051284480" target="_blank" rel="noopener noreferrer">Paris climate accord</a> on Day One of his administration. He also has appointed an impressive and diverse climate change team to take key administration positions, including New Mexico Rep. Deb Haaland, who co-sponsored the Green New Deal, to run the Interior Department; North Carolina Department of Environmental Quality head Michael Regan to lead the Environmental Protection Agency; former Environmental Protection Agency chief Gina McCarthy as national climate advisor; and former Secretary of State John Kerry, who helped negotiate the Paris climate agreement, to serve as his international climate envoy.</p><p>That's a welcome relief, because the world is running out of time. In 2020 alone, wildfires burned millions of acres in Australia and California to a crisp; heat waves scorched Europe, Asia and the Arctic; floods inundated the U.S. Midwest as well as nations in Africa and Asia; and a record-breaking Atlantic hurricane season battered the coasts of Central America, Caribbean islands and the United States.</p><p>But for all the promises President-elect Biden has made, some nagging questions remain: Given the constraints of a closely divided Congress, how much will the Biden administration truly be able to accomplish? And even with the United States rejoining the Paris accord, will countries live up to its promise to keep the Earth's temperature in check?</p><p>For some answers, I turned to <a href="https://www.ucsusa.org/about/people/rachel-cleetus" target="_blank" rel="noopener noreferrer">Climate and Energy Program Policy Director Rachel Cleetus</a>, who I last <a href="https://blog.ucsusa.org/elliott-negin/what-do-you-see-as-the-most-important-elements-of-a-post-pandemic-economy" target="_blank" rel="noopener noreferrer">interviewed in May</a> about what a post-pandemic economy should look like. The questions I posed to her this time around are a logical extension of the conversation we had then.</p>
<p><strong>EN: Before we dig into what we can expect from the incoming Biden administration, let's talk about what Congress included in the pandemic relief package it passed just before Christmas. I don't know about you, but I was pleasantly surprised to learn that it included some good climate-related provisions. Does this suggest that the next Congress will take climate change seriously?</strong></p><p>RC: The omnibus pandemic relief bill Congress just passed was long overdue and desperately needed, given the fact that millions of people are in increasingly dire economic straits. It also included a provision to dramatically reduce the use of hydrofluorocarbons (HFCs), extremely potent heat-trapping gases used in air conditioners and refrigerators; an extension of renewable electricity production and investment tax credits, which will help boost clean energy and create jobs; support for energy storage technology research and development; and increased funding for ARPA-E, the Department of Energy's technology innovation program. The bill also included a one-year extension of the Black Lung Disability Trust Fund, a welcome but inadequate provision as black lung disease hits record levels in coal country.</p><p>The <a href="https://blog.ucsusa.org/shana-udvardy/congress-continues-to-affirm-that-climate-security-is-national-security" target="_blank" rel="noopener noreferrer">National Defense Authorization Act</a>, which Congress just passed with an overwhelming bipartisan override of President Trump's veto, also includes provisions recognizing the impact of climate change on the military and the need to invest in resilience measures.</p><p>These provisions demonstrate that Congress can act in a bipartisan manner on clean energy and climate change issues. But much more will be needed in the months and years ahead to make steep cuts in global warming emissions and achieve comprehensive, bold and just climate policies that benefit everyone. Congress has yet to demonstrate the will to act commensurately with the scale of the challenges we face, which is why we will need to continue to pressure policymakers to do the right thing after the new Congress and administration take office.</p>
<p><strong>EN: Notwithstanding the fact that leading Republicans supported the climate-related elements of the pandemic relief package, how much will the incoming Biden administration have to rely on executive orders to advance initiatives to combat climate change? After all, the oil and gas industry still has a great deal of influence over Congress.</strong></p><p>RC: President Biden should send a clear and strong signal, early on, that he is committed to using his full powers to advance climate action through executive authorities and regulations. Here are some of the <a href="https://blog.ucsusa.org/rachel-cleetus/biden-climate-priorities" target="_blank" rel="noopener noreferrer">most important actions on climate</a> that he should take, many of which could be done within the first 100 days and some which should happen via a Day One executive order on climate change:</p><ul><li>Set science-informed climate goals and commit the United States to reaching net-zero carbon emissions economywide no later than 2050, and at least 50 percent below 2005 levels by 2030.</li><li>Direct all federal agencies to incorporate climate science into their actions and develop updated climate action plans.</li><li>Initiate administrative and regulatory actions to sharply curtail heat-trapping emissions economywide and advance climate resilience, prioritizing investments in historically marginalized communities.</li><li>Rejoin the Paris agreement, with an ambitious commitment to cut heat-trapping emissions and provide climate funding for developing countries, in line with the US fair share contribution to global climate goals.</li><li>Reverse the Trump administration's egregious executive orders that have halted, undermined, and reversed climate action.</li><li>Create White House-level offices focused on environmental justice and economic transition to elevate and mainstream these priorities.</li></ul><p>As you note, opposition from the fossil fuel companies is not going away any time soon. They may continue to try to slow down or stop climate action, or at best support incremental policy changes that preserve their profits—even as they <a href="https://ucsusa.org/about/news/exxonmobils-five-year-emissions-reduction-plan-too-lievettle-too-late" target="_blank" rel="noopener noreferrer">claim to endorse</a> the Paris agreement's net-zero goal.</p><p>UCS and its coalition partners will continue to engage in sharp and strategic corporate campaigns to expose their disingenuous actions, <a href="https://blog.ucsusa.org/kathy-mulvey/bankrolling-climate-disaster-stop-the-money-pipeline-to-fossil-fuel-companies" target="_blank" rel="noopener noreferrer">curtail their Wall Street financing</a>, and prod them to align their business models with what the science demonstrates is necessary. We will continue to push for companies to <a href="https://blog.ucsusa.org/nicole-pinko/climate-risk-disclosure-act-is-good-for-your-investments" target="_blank" rel="noopener noreferrer">disclose their climate risks</a>, and for <a href="https://www.ucsusa.org/about/news/trading-commission-report-sends-clear-signal-climate-change-risks-us-economy-0" target="_blank" rel="noopener noreferrer">financial regulators</a> to require this. And we support the rights of affected parties to seek legal accountability for climate damages caused by fossil fuel companies.</p>
<p><strong>EN: OK. So what can a narrowly divided Congress accomplish?</strong></p><p>RC: Congress also will have to step up to play its part. We are coming off a year of record-breaking climate related disasters—including wildfires, hurricanes, floods, and heatwaves—which intersected cruelly with the coronavirus pandemic and the resulting ongoing economic crisis. People across the country need Congress to do its job. Securing robust, comprehensive, durable climate and clean energy policy will require legislation.</p><p>President Biden should immediately begin working with the new Congress to advance a suite of policies that ramp up clean energy, drive down carbon emissions economywide, and build climate resilience, while also addressing longstanding environmental injustices that have disproportionately affected low-income communities and communities of color and ensuring a fair transition for coal communities. Breaking through the long-standing political logjam won't be easy, but the needs are urgent and the economic, health and climate benefits of a low-carbon climate-resilient economy are clear.</p><p>Many of these policy priorities were highlighted in the <a href="https://joebiden.com/joes-vision/" target="_blank" rel="noopener noreferrer">Biden-Harris campaign platform</a>. The incoming administration must do all it can to prod Congress to pass legislation addressing them. Here's just a partial list of what we need:</p><p><em><strong>Additional pandemic relief and economic recovery packages</strong></em>. More funding for public health priorities and economic relief is desperately needed at the national, state and local level. Congress should include a robust "green" economic recovery package to jumpstart and foster a just and equitable economic recovery, with job creation driven by investments in clean energy and climate resilient infrastructure. Forty percent of these investments should directly benefit historically marginalized communities.</p><p><em><strong>Fair transition for workers and communities</strong></em>. Congress should pass a comprehensive, well-funded transition package for displaced workers and communities hurt by the country's ongoing transition away from coal.</p><p><em><strong>Environmental justice</strong></em>. Congress should strengthen public health safeguards, tighten enforcement, and invest in cleaning up the cumulative toxic burden of pollution in fence-line and frontline communities, which are disproportionately low-income communities and communities of color.</p><p><em><strong>Recognition of climate change's financial and economic risks</strong></em>. Congress should pass legislation to ensure that financial regulators require corporations to disclose their climate risk to ensure they—and the market more broadly—are appropriately accounting for such risks and taking steps to mitigate it.</p><p><em><strong>Guaranteed community access to the courts</strong></em>. As a mounting number of cities, counties and states seek to hold fossil fuel companies accountable for climate damages and fraud, here's one thing Congress should not do: pass laws attempting to limit or eliminate communities' access to the courts to seek redress.</p>
<p><strong>EN: President-elect Biden recently <a href="https://twitter.com/JoeBiden/status/1340427943051284480" target="_blank" rel="noopener noreferrer">proclaimed</a> that he will "put America back in the business of leading the world on climate change." What should that mean in concrete terms? As the country responsible for the largest share of cumulative carbon emissions to date, what does the United States have to do regain international respect and provide leadership?</strong></p><p>RC: To be perfectly frank, the Biden administration will have to do a lot more than trot out tired rhetoric about US leadership on climate action.</p><p>What the country and the rest of the world need is for the United States to take its place at the table, alongside and in cooperation with nations large and small, and do its part responsibly, fairly and consistently. The Biden administration and Congress need to enact strong national climate policies and make an ambitious, credible emissions reduction commitment ahead of the next international climate talks. They also must commit to scaled-up climate finance for developing countries. Finally, they have to work together with states, cities, tribal governments, businesses, and local stakeholders, many of whom have contributed to significant climate progress despite the absence of national leadership in the last four years. It's time—well past time, actually—for meaningful federal action.</p>

A fast-spreading variant of the coronavirus that causes COVID-19 has been found in at least 10 states, and people are wondering: How do I protect myself now?
<p>We saw what the new variant, known as B.1.1.7, can do as it <a href="https://www.sciencemag.org/news/2020/12/mutant-coronavirus-united-kingdom-sets-alarms-its-importance-remains-unclear" target="_blank">spread quickly through southeastern England</a> in December, causing case numbers to spike and triggering stricter lockdown measures.</p><p>The new variant has been estimated to be <a href="https://cmmid.github.io/topics/covid19/uk-novel-variant.html" target="_blank">50% more easily transmitted than common variants</a>, though it <a href="https://www.cdc.gov/mmwr/volumes/70/wr/mm7003e2.htm?s_cid=mm7003e2_e" target="_blank" rel="noopener noreferrer">appears to affect people's health in the same way</a>. The increased transmissibility is believed to arise from a <a href="https://www.biorxiv.org/content/10.1101/2020.12.29.424708v1" target="_blank" rel="noopener noreferrer">change in the virus's spike protein</a> that can allow the virus to more easily enter cells. These and other <a href="https://doi.org/10.1101/2020.12.24.20248834" target="_blank" rel="noopener noreferrer">studies on the new variant</a> were released before peer review to share their findings quickly.</p><p>Additionally, there is some evidence that patients infected with the new B.1.1.7 variant may have a <a href="https://www.medrxiv.org/content/10.1101/2020.12.24.20248834v1.full" target="_blank" rel="noopener noreferrer">higher viral load</a>. That means they may expel more virus-containing particles when they breathe, talk or sneeze.</p><p>As professors who study <a href="https://www.clarkson.edu/people/byron-erath" target="_blank" rel="noopener noreferrer">fluid dynamics</a> <a href="https://www.clarkson.edu/people/suresh-dhaniyala" target="_blank" rel="noopener noreferrer">and aerosols</a>, we investigate how airborne particles carrying viruses spread. There is still a lot that scientists and doctors don't know about the coronavirus and its mutations, but there are some clear strategies people can use to protect themselves.</p>
Airborne Particles Are Still the Biggest Problem
<p>The <a href="https://theconversation.com/why-it-matters-that-the-coronavirus-is-changing-and-what-this-means-for-vaccine-effectiveness-152383" target="_blank" rel="noopener noreferrer">SARS-CoV-2 variants</a> are believed to spread primarily through the air rather than on surfaces.</p><p>When someone with the coronavirus in their respiratory tract coughs, talks, sings or even just breathes, infectious respiratory droplets can be expelled into the air. These droplets are tiny, predominantly in the range of <a href="https://www.sciencedirect.com/science/article/pii/S0021850211001200?casa_token=KtyrsEfbeqcAAAAA:vv10sSxm33tzg0EQvNMIFtV7GCu5gE9QAzuyzHKr2_4Cl0OFkUJoGwzn4d0ZnEWS19NsOTuH" target="_blank" rel="noopener noreferrer">1-100 micrometers</a>. For comparison, a human hair is about 70 micrometers in diameter.</p><p>The larger droplets fall to the ground quickly, rarely traveling farther than 6 feet from the source. The bigger problem for disease transmission is the tiniest droplets – those less than 10 micrometers in diameter – which can remain suspended in the air as aerosols for <a href="https://academic.oup.com/cid/article/50/5/693/325466" target="_blank">hours at a time</a>.</p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="bb67b83dcafe589f350daf3df60fa29d"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/UNCNM7AZPFg?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>With people possibly having more virus in their bodies and the virus being more infectious, everyone should take extra care and precautions. Wearing face masks and social distancing are essential.</p><p>Spaces and activities that were previously deemed "safe," such as some indoor work environments, may present an elevated infection risk as the variant spreads.</p><p>The concentration of aerosol particles is usually highest right next to the individual emitting the particles and decreases with <a href="https://aip.scitation.org/doi/10.1063/5.0025476" target="_blank">distance from the source</a>. However, in indoor environments, aerosol concentration levels can quickly build up, similar to how <a href="https://theconversation.com/what-a-smoky-bar-can-teach-us-about-the-6-foot-rule-during-the-covid-19-pandemic-145517" target="_blank" rel="noopener noreferrer">cigarette smoke accumulates within enclosed spaces</a>. This is particularly problematic in spaces that have poor ventilation.</p><p>With the new variant, aerosol concentration levels that might not have previously posed a risk could now lead to infection.</p>

What Can You Do to Stay Safe?
<p>1) Pay attention to the type of face mask you use, and how it fits.</p><p>Most off-the-shelf face coverings are not 100% effective at preventing droplet emission. With the new variant spreading more easily and likely infectious at lower concentrations, it's important to select coverings with materials that are most effective at stopping droplet spread.</p><p>When available, N95 and surgical masks consistently perform the best. Otherwise, face coverings that use <a href="https://www.sciencedirect.com/science/article/pii/S2352431620301802?casa_token=-Dj6nGBAm24AAAAA:qq9BpbzCKaPDFcV73ohA2fCnhE_Zlkss6Bei3kUwq9QYndhHj0Vafbbd-ef_855lx6knDfUt" target="_blank">multiple layers of material</a> are preferable. Ideally, the material should be a tight weave. High thread count cotton sheets are an example. Proper fit is also crucial, as gaps around the nose and mouth can <a href="https://pubs.acs.org/doi/10.1021/acsnano.0c03252" target="_blank" rel="noopener noreferrer">decrease the effectiveness by 50%</a>.</p><p>2) Follow social distancing guidelines.</p><p>While the current social distancing guidelines are not perfect – <a href="https://theconversation.com/what-a-smoky-bar-can-teach-us-about-the-6-foot-rule-during-the-covid-19-pandemic-145517" target="_blank" rel="noopener noreferrer">6 feet isn't always enough</a> – they do offer a useful starting point. Because aerosol concentrations levels and infectivity are highest in the space immediately surrounding anyone with the virus, increasing physical distancing can help reduce risk. Remember that people are infectious <a href="https://medical.mit.edu/faqs/COVID-19#faq-10" target="_blank" rel="noopener noreferrer">before they start showing symptoms</a>, and they many never show symptoms, so don't count on seeing signs of illness.</p><p>3) Think carefully about the environment when entering an enclosed area, both the ventilation and how people interact.</p><p>Limiting the size of gatherings helps reduce the potential for exposure. Controlling indoor environments in other ways can also be a highly effective strategy for reducing risk. This includes <a href="https://theconversation.com/what-a-smoky-bar-can-teach-us-about-the-6-foot-rule-during-the-covid-19-pandemic-145517" target="_blank" rel="noopener noreferrer">increasing ventilation rates</a> to bring in <a href="https://theconversation.com/keeping-indoor-air-clean-can-reduce-the-chance-of-spreading-coronavirus-149512" target="_blank" rel="noopener noreferrer">fresh air and filtering existing air</a> to dilute aerosol concentrations.</p><p>On a personal level, it is helpful to pay attention to the types of interactions that are taking place. For example, many individuals shouting can create a higher risk than one individual speaking. In all cases, it's important to minimize the amount of time spent indoors with others.</p><p>The CDC has warned that B.1.1.7 could <a href="https://www.cdc.gov/mmwr/volumes/70/wr/mm7003e2.htm?s_cid=mm7003e2_w" target="_blank" rel="noopener noreferrer">become the dominant SARS-CoV-2 variant</a> in the U.S. by March. Other fast-spreading variants have also been found in <a href="https://virological.org/t/genomic-characterisation-of-an-emergent-sars-cov-2-lineage-in-manaus-preliminary-findings/586" target="_blank" rel="noopener noreferrer">Brazil</a> and <a href="https://www.who.int/csr/don/31-december-2020-sars-cov2-variants/en/" target="_blank" rel="noopener noreferrer">South Africa</a>. Increased vigilance and complying with health guidelines should continue to be of highest priority.</p>From Your Site Articles
