Stephen Hawking's Final Warnings Urged World to Halt Climate Change

Stephen Hawking, one of the greatest minds on Earth, died peacefully at his home in Cambridge on Wednesday at the age of 76.
As well as being a renowned physicist whose groundbreaking theories helped us understand the complexities of space, time and the universe, the British professor also taught us about our home planet.
In his last years, Hawking used his platform to warn that human activity is causing irreversible planetary damage and that we must take action to halt climate change.
"Climate change is one of the great dangers we face, and it's one we can prevent," Hawking said in May.
Hawking frequently denounced climate change deniers, and even offered to pay their trip to Venus to illustrate the impact of greenhouse gases on a habitable planet. The global thinker also warned that the Brexit vote would damage scientific research in Britain and criticized President Donald Trump's decision to withdraw the U.S. from the Paris agreement.

"I am not denying the importance of fighting climate change and global warming, unlike Donald Trump, who may just have taken the most serious, and wrong, decision on climate change this world has seen," Hawking said last year about the Paris withdrawal.
In a 2016 lecture, he predicted that humanity has only 1,000 years left on Earth and we must find another planet to live on.
"[W]e must ... continue to go into space for the future of humanity," Hawking said. "I don't think we will survive another 1,000 years without escaping beyond our fragile planet."
According to Hawking, Earth and its inhabitants could soon be doomed. But, as he wrote in 2016, he's actually an "enormous optimist" for our future—that is, if we can learn to work together.
"Perhaps in a few hundred years, we will have established human colonies amid the stars, but right now we only have one planet, and we need to work together to protect it," he wrote. "To do that, we need to break down, not build up, barriers within and between nations."
"We can do this, I am an enormous optimist for my species; but it will require the elites, from London to Harvard, from Cambridge to Hollywood, to learn the lessons of the past year. To learn above all a measure of humility."
Hawking died from complications of Lou Gehrig's disease, which he suffered from since he was 20.

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>

As the COVID-19 pandemic continues to keep most of Europe on pause, the EU aims for a breakthrough in its space program. The continent is seeking more than just a self-sufficient space industry competitive with China and the U.S.; the industry must also fit into the European Green Deal.
<h3>'Strategic Autonomy' in Space</h3><p>"I believe we need a more offensive and aggressive strategy," said the European Commissioner Thierry Breton as he laid out the main priorities for the EU space program over the next seven years. Breton said that the European Union must move quickly to reduce its dependence on third countries.</p>
<div id="dc9fc" class="rm-shortcode" data-rm-shortcode-id="e59073f4aedd26372600b247d6be1cec"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1348914516969611267" data-partner="rebelmouse"><div style="margin:1em 0">"Enhancing Europe's strategic autonomy in space is not an option" @ThierryBreton #BBESpaceConf https://t.co/Qm9gOeUh4v</div> — Business Bridge Europe (@Business Bridge Europe)<a href="https://twitter.com/BBE_Europe/statuses/1348914516969611267">1610441257.0</a></blockquote></div>
<p>"Strategic autonomy" is Brussels's latest catchphrase that echoed throughout Breton's and other EU officials' speeches during the 13th European Space Conference earlier this week. As Europe plans to address economic needs within its borders, its aerospace program is set to focus inwards as well.</p><p>Breton mentioned having independent EU-wide internet coverage as another important target. Noting that "attacks on the internet are not fiction anymore," Breton explained that the EU must construct a secure broadband network.</p><p>He also emphasized that the European Commission needs to promote entrepreneurship and innovation in space, while continuing to expand its existing projects. Otherwise, he said, Galileo and Copernicus – Europe's major satellite projects – will soon become obsolete.</p><p>After these plans receive approval from European governments and the European Parliament, €15 billion ($18.2 billion) will fund space sector projects during the 2021-2027 period, in addition to current funding from national governments and private investments.</p>
<h3>Meeting the Competition and Climate Goals</h3><p>During the past decade, the number of satellite launches and space missions has surged internationally. China's lunar rover landed on the far side of the moon. Private companies in the U.S. have made rapid advancements too. SpaceX successfully returned two of its reusable rocket cores to Earth.</p><p>As vital infrastructure like transportation and communications rely more and more on space technology, there's a greater sense of urgency for the EU to realize its own space ambitions.</p><p>The continent's other pressing objective is to become carbon neutral by 2050. Expansion of EU aerospace activities – now heavily dependent on the production of metal and fuel – must comply with the European Green Deal.</p><p>Alignment of these two goals might not be straightforward, but in the view of EU officials, the space program has a role to play in fighting climate change, fostering green technologies like clean fuels and optimized farming. Additionally, data and services from space are used to constantly monitor the Earth and measure things like CO2 levels.</p><p>EU officials and entrepreneurs mentioned clean fuel production and satellite monitoring missions as two promising areas to help achieve Europe's Green Deal and other environmental targets.</p>
<h3>Clean Energy in Space and on Earth</h3><p>One of the areas in which European space companies have a leg up is the production of liquid hydrogen as fuel. When liquid hydrogen burns, it produces enough propelling force to launch a rocket, but emits only water vapor and warm air. However, it's highly energy-intensive to produce, creating a large carbon footprint. The focus of European firms working on this energy option is to mitigate the impact of liquid hydrogen production on the environment.</p><p>"Hydrogen (as fuel) is expensive today but tomorrow it will be cheap and green," said Xavier Vigor, vice president of Air Liquide, a supplier of industrial gases.</p><p>European rockets have used liquid hydrogen as their fuel for decades. ArianeGroupe, the continent's largest launcher company, aims to launch its carbon-neutral rockets running on hydrogen produced from biomass by 2030. The company also plans to bring the clean fuel to the transport industry. If they succeed, ships and airplanes will be able to travel around the globe, producing no carbon emissions.</p><p>"I am really thankful for the decisionmakers in Europe who made the decision to use hydrogen for European launchers. This was a brilliant bet," said Jean-Christophe Henoux, ArianeGroup's vice president of Future Programmes.</p>
<h3>Satellites Monitoring Climate Change</h3><p>EU officials are confident their satellite program will also help in the fight against climate change. The EU space program will continue to design missions focused on CO2 monitoring and a polar observation by its satellites.</p><p>"Satellite programs such as Galileo and Agnus have already had an important contribution to minimizing our environmental footprint," said Rodrigo da Costa, the head of the European Global Navigation Satellite Systems Agency (GSA), in a press briefing.</p><p>Copernicus, the EU's Earth observation system, has monitored climate change since 2017, providing historical data and climate models for the future.</p>
<img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ5Nzk2MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY3MjI1Njk4Mn0.PSKtNrh_kWGzH6vsGlHWBFLvLHYYGbX30YsZh5jLmuc/img.jpg?width=980" id="bcf7e" class="rm-shortcode" data-rm-shortcode-id="9a55c41003928d33600334310f11fbf6" data-rm-shortcode-name="rebelmouse-image" data-width="700" data-height="394" />
European satellites continue to provide data on climate change.
<p>"We believe we can create synergies between navigation and Earth observation," said da Costa. Better navigation helps shorten transportation routes, which cuts fuel consumption. This is how EU satellite programs can contribute to the implementation of the Green Deal, according to da Costa.</p><p>Full details of the European space plan have yet to be worked out. The European Commission will meet to decide on them in the coming weeks. After that, a consortium of aerospace and telecom companies will start working to operationalize the plan.</p>

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>

<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>.

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>

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>

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>
