Just a few weeks after U.S. President-Elect Donald Trump, a critic of climate change science, told New York Times journalists he had an “open mind” on climate change, he and his daughter Ivanka met with former vice president and climate advocate Al Gore.
“I had a lengthy and very productive session with the president-elect,” said Gore of Trump. “It was a sincere search for areas of common ground. I had a meeting beforehand with Ivanka Trump. The bulk of the time was with the president-elect, Donald Trump. I found it an extremely interesting conversation, and to be continued.”
Though Trump and Gore’s topic of discussion wasn’t directly referenced in his statement, it is speculated that climate change was on the list. The Washington Post reports that an aide to Gore, who spoke on the condition of anonymity, said the former vice president “made clear in his statements following the election that he intended to do everything he could to work with the president-elect to ensure our nation remains a leader in the effort to address the climate crisis.”
Regarding the meeting with Ivanka, however, Gore was more forthcoming.
“It’s no secret that Ivanka Trump is very committed to having a climate policy that makes sense for our country and for our world,” Gore said. “And that was certainly evident in the conversation that I had with her before the conversation with the President-elect.”
Trump’s EPA: Leader Tapped
U.S. President-Elect Donald Trump has tapped Oklahoma Attorney General Scott Pruitt to replace current U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy. The nomination seems to follow with Trump’s campaign promises to rollback EPA regulations.
“For too long, the Environmental Protection Agency has spent taxpayer dollars on an out-of-control anti-energy agenda that has destroyed millions of jobs, while also undermining our incredible farmers and many other businesses and industries at every turn,” said Trump in a statement. “As my EPA Administrator, Scott Pruitt, the highly respected Attorney General from the state of Oklahoma, will reverse this trend and restore the EPA’s essential mission of keeping our air and our water clean and safe.”
Pruitt, whose biography indicates he is a “leading advocate against the EPA’s activist agenda,” offered that he intends to run the EPA in a way that “fosters both responsible protection of the environment and freedom for American businesses.”
Pruitt was one of two rumored candidates for this post who have called for significant rollbacks in regulations. He has sued the EPA over its regulations to reduce greenhouse gas emissions from power plants under the Clean Air Act. In an interview with Reuters in September, Pruitt said that he sees the Clean Power Plan as a form of federal “coercion and commandeering” of energy policy and that his state should have “sovereignty to make decisions for its own markets.”
Warming Could Dramatically Increase Soil Carbon Losses
A study published last week in the journal Nature documents how carbon loss in soil worsens climate change. The 25-year study finds that as the planet warms, the respiration of microorganisms in soils increases, releasing greenhouse gases such as carbon dioxide and methane. The scientists’ compilation of 49 empirical studies of soil carbon emissions from plots around the world revealed that climate change will lead to the loss of at least 55 trillion kilograms of carbon from the soil by mid-century.
“It’s of the same order of magnitude as having an extra U.S. on the planet,” said Thomas Crowther, a co-author with the Netherlands Institute of Ecology.
The study found that carbon losses will be greatest in colder places at high latitudes and altitudes—places that have massive carbon stocks but that have largely been missing from previous research.
Correction: In last week’s story about an Arctic Council report on climate and other changes in the Arctic, we should have said that temperatures in the region had reached 9–12 degrees Celsius (16–22 degrees Fahrenheit) above seasonal averages.

Climate-change-related environmental, ecological, and social changes in the Arctic are accelerating and are more extreme than ever recorded, undermining the sustainability of current ways of life in the region and potentially destabilizing climate and ecosystems around the world, according to a five-year report released last week by the Arctic Council, an intergovernmental organization formed to protect the region.
“Arctic social and biophysical systems are deeply intertwined with our planet’s social and biophysical systems, so rapid, dramatic and unexpected changes in this sensitive region are likely to be felt elsewhere,” the report states. “As we are often reminded, what happens in the Arctic doesn’t stay in the Arctic.”
The report noted that the Greenland Ice Sheet, which was thought to be resistant to climate change, is experiencing higher-than-expected thinning “over time scales of only years” due to warmer temperatures caused by climate change and that if it melts completely, global sea levels would rise an average of 7.4 meters.
The report outlines 19 “regime shifts” under way or on the horizon absent efforts to halt them. They range from sea-ice-free summers to ocean circulation changes and collapse of some Arctic fisheries.
“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the co-authors of the report. “[These developments] also make the potential for triggering [tipping points] and feedback loops much larger.”
Trump Transition: EPA Prospects
Just days after stating his “open mind” to confronting climate change, president-elect Donald Trump was meeting with potential prospects to run the U.S. Environmental Protection Agency (EPA) that would align with his campaign promises to roll back agency regulations.
Two rumored EPA leaders who have called for a significant rollback in regulations—Oklahoma Attorney General Scott Pruitt and former Texas environmental regulator Kathleen Hartnett White—were scheduled to meet with Trump this week.
In an interview with McClatchy, White confirmed her consideration for the post, which she says she would take on with a new approach to address a “shifting environmental landscape.” White also shared details of her conversation with Trump.
“He wants the EPA to run more carefully, to use stronger science and be unabashedly conscientious to the effect of more and more rules on existing employment and job creation,” she said. “I have no desire to put words in his mouth. But as he is in other areas, he likes a good deal.”
Climate Change Conference in Marrakech Concludes
The United Nations Framework Convention on Climate Change (COP22), which brought nearly 200 countries together to hammer out the details of last year’s Paris Agreement, concluded last month. What exactly came out of the two-week conference?
- A timeline for implementing the Paris Agreement, which aims to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. Countries participating in COP22 decided to complete detail setting for the agreement by 2018 and to review progress in 2017.
- The Marrakech Action Proclamation. The one-page document reaffirms countries’ commitments to the Paris Agreement’s goals following the election of Donald Trump as the next U.S. president. On the campaign trail, Trump stated intentions to end U.S. involvement in the agreement.
- Forty-eight of the world’s poorest and most vulnerable countries pledged to turn in more ambitious targets to Paris before 2020 and to shift to 100 percent renewable energy use by 2050.
- An agreement to continue the discussion on climate finance. There’s still uncertainty surroundingthe pathway to mobilizing $100 billion in climate finance for developing countries by 2020, to establishing rules for reporting finance, and to scaling up adaptation finance.
- Nations also agreed on a five-year work-plan on “loss and damage” to address issues beyond climate adaptation like slow-onset impacts of climate change, non-economic losses and migration.

Businessman Donald Trump became the next U.S. president-elect early Wednesday after beating his opponent, former Secretary of State Hillary Clinton. Trump’s win could have great implications for the environment, as he’s promised a shift from the Obama administration’s energy and climate policies.
What could his presidency mean for energy policy? It may take some time to evaluate what part of President Trump’s statements remain in the realm of the campaign, and what provides the guiding points for how he will govern.
One thing seems clear—Trump has voiced plans to eliminate the U.S. Environmental Protection Agency’s Clean Power Plan. Based on Section 111(d) of the Clean Air Act, the Clean Power Plan was first proposed in June 2014 to put limits on greenhouse gas emissions from existing fossil fuel-fired power plants and was finalized in August 2015. In setting those limits, the rule considers states’ ability to shift power generation to cleaner sources.
Currently, the Clean Power Plan is being reviewed by the U.S. Court of Appeals in the D.C. Circuit as a result of a suit brought by 27 states and some corporate interests over whether the EPA properly exercised its authority under the Clean Air Act. The case is expected to go to the Supreme Court next year—where the next president’s pick for a vacant court seat could determine the rule’s fate.
Other commentators have noted that Trump could decide to stop defending the Clean Power Plan in court, take steps to rescind the rule, or seek Congressional support for blocking it.
But the Clean Power Plan is not the only environmental measure facing uncertainty. Trump has voiced his intention to repeal federal spending on renewable energy in favor of a more “fossil fuel-centric” energy policy. Nevertheless, Forbes reports, utility-scale solar and wind, which have grown consistently due to lower costs, will continue to thrive under Trump.
More dramatically, Trump’s campaign statements even called into question if and how much of the EPA remains. In previous speeches, like one delivered at a March GOP debate, Trump proposed dismantling the EPA and naming climate change skeptic, Myron Ebell of the Competitive Enterprise Institute to head the EPA transition team.
I’d “get rid of [the EPA] in almost every form,” Trump said. “We are going to have little tidbits left but we are going to take a tremendous amount out.”
His presidency could also have implications for the Paris Agreement, which aims to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius.
But Trump has vowed to withdraw from the agreement, which officially came into force Nov. 4 and which global leaders are discussing this week in Marrakech, Morocco. Pulling out of the climate agreement would not require senate approval and could be done in a variety of ways. The effect could be substantial, according to analysis by Climate Interactive, because a large chunk—20 percent—of emissions cuts produced under the agreement come from the U.S., the world’s second largest emitter.
“If the U.S. pulls out of this, and is seen as going as a rogue nation on climate change, that will have implications for everything else on President Trump’s agenda when he wants to deal with foreign leaders,” said Alden Meyer of the Union of Concerned Scientists at the U.N.’s annual gathering in Marrakech.
Nations Grapple with Implementation of Paris Agreement; UN Says World Off Path to Meet Its Goal
A day before election results were finalized, the World Meteorological Organization (WMO) said that 2011–2015 was the hottest five-year period on record, evidencing an “increasingly visible human footprint.” The likelihood of many extreme events during the period was increased, according to the WMO, as a result of man-made climate change. The probability of some extreme high temperatures rose by a factor of 10 or more. The authors also said that 2016 will probably break the record for warmest year.
The report was released in Marrakech, Morocco, where nearly 200 nations are meeting at the 22nd Conference of the Parties (COP22), the annual United Nations (U.N.) climate conference, to begin hammering out details regarding how they are going to live up to their pledges to reduce emissions of carbon dioxide and other greenhouse gases under the Paris Agreement. Delegates’ goal: to come up with a work plan for the next two years, at the end of which they’ll assess progress on implementing the agreement’s measures.
COP22 comes on the heels of the unexpectedly quick entry into force of the agreement—and none too soon finds another report from the U.N. Environment Programme (UNEP) that suggests the pledges underpinning the agreement will put the world on course for a temperature rise of 2.9 to 3.4 degrees Celsius this century.
A scientific assessment of how countries’ actions and pledges tally with emissions trajectories consistent with the long-term goal of the United Nations Framework Convention on Climate Change, the report suggests that 2030 emissions will be 12 to 14 gigatons above levels needed to limit global warming to 2 degrees Celsius and 15 to 17 gigatons above levels needed to limit it to 1.5 degrees—even with follow through on Paris pledges.
“We are moving in the right direction: the Paris Agreement will slow climate change, as will the recent Kigali Amendment to reduce HFCs,” said UNEP Executive Director Erik Solheim. “They both show strong commitment, but it’s still not good enough if we are to stand a chance of avoiding serious climate change. If we don’t start taking additional action now, beginning with the upcoming climate meeting in Marrakesh, we will grieve over the avoidable human tragedy. The growing numbers of climate refugees hit by hunger, poverty, illness and conflict will be a constant reminder of our failure to deliver. The science shows that we need to move much faster.”
The report points to energy efficiency and action by non-state actors—the private sector, cities, regions, and other sub-nationals—as ripe for reducing the emissions gap.
EPA Finalizes Voluntary Carbon Trading Model for Clean Power Plan Compliance
Last week, the EPA forwarded a voluntary carbon trading model for Clean Power Plan compliance to the Office of Management and Budget for review. The model rules would allow states to comply with the federal carbon regulations for reducing emissions from power plants by participating in an optional emissions trading program. It would also earn states additional credit for early investments in alternative energy through a finalized Clean Energy Incentive Program.
A lot of states and electric utilities are interested in carbon trading, E&E News reported, because modeling suggests it is likely the simplest and least expensive way to meet Clean Power Plan goals (subscription).
The Climate Post offers a rundown of the week in climate and energy news. It is produced each Thursday by Duke University’s Nicholas Institute for Environmental Policy Solutions.
What was scheduled to be about 3.5 hours turned into nearly seven on Tuesday as 10 judges heard oral arguments in a rare “en banc” review of the Clean Power Plan in the U.S. Court of Appeals for the District of Columbia Circuit.
The controversial Clean Power Plan, based on Section 111(d) of the Clean Air Act, was first proposed in June 2014 to limit greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants. In setting those limits, the rule considers the ability to shift power generation to cleaner sources. Its supporters argue that the act gives the U.S. Environmental Protection Agency (EPA) the authority to regulate greenhouse gas emissions from power plants in this way. Its challengers allege the rule amounts to executive overreach because the EPA is effectively forcing owners and operators of coal plants to invest in their competitors—cleaner natural gas or renewable energy. They also contend that the rule undercuts the reliability of the electric grid by forcing coal-fired power plants offline. Moreover, opponents argue that EPA cannot regulate power plants under Section 111(d) in the first place because EPA already limits emissions like mercury under Section 112 of the act. Until these challenges are resolved, the Supreme Court has delayed implementation of the rule.
I was at the Tuesday hearing and wrote about some early takeaways for Bloomberg Government. From my seat in the courtroom, they included:
- It’s now clear that the EPA possesses the authority to regulate greenhouse gases as a pollutant under the Clean Air Act. The question now is whether the methods used by the EPA were permitted under the act. As Judge Tatel noted, the Supreme Court “did that work” in Massachusetts v. EPA.
- The case is caught up in a larger judicial discussion about how much deference to grant the executive branch. As Congress increasingly fails to legislate on major political issues of our day, the executive branch has been looking to existing statutes for the authority to address problems. But the courts are debating whether to provide the traditional broad deference to agencies as they pursue these initiatives, or whether “major” political issues require more scrutiny. EPA’s Clean Power Plan evoked this debate, and as a result may create more precedent that will guide future presidents on the extent of their power.
- The court repeatedly reflected on the Supreme Court’s AEP v. Connecticut ruling, which established that the EPA had the authority to regulate existing power plants and thereby forbade Connecticut from suing those plant owners directly. Any victory for the petitioners in this case will need to explain why that recognition of authority in AEP v. Connecticut does not presume that the EPA possesses the authority underlying the Clean Power Plan.
- Several jurists expressed concern that industry was arguing that the EPA could not consider the shifting of generation to cleaner sources in setting the standard, but nonetheless wanted that low cost option as a means of complying with the rule. Can the industry have its cake and eat it, too?
- The judges’ proficiency in understanding the electric grid was impressive, clearly aided by legal briefs from grid operators. What was not as clear, however, is whether this proficiency had convinced them that managing the generation sources across that system constituted the “best system of emissions reduction” under the act.
Although it is difficult to guess a case’s outcome from any oral argument, all in all the government came through it with clear indications of support from three or four judges. At least four other judges, however, either did not speak or evaluated the case in such a Socratic manner that their positions were more mysterious. With six votes needed for a win, supporters of the rule will be holding their breath until the opinion appears. Overall, the final word on the Clean Power Plan may not come until 2018 or later.
Presidential Debate Highlights Stark Contrasts on Climate Change, Energy Policy
Climate change and energy policy were touched on in the first debate between the 2016 Democratic and Republican presidential nominees on Monday. Early on, Hillary Clinton, former secretary of state, accused businessman and opponent Donald Trump of dismissing climate change as a hoax created by China to harm American competitiveness—a point Trump denied.
“Donald thinks that climate change is a hoax, perpetrated by the Chinese,” said Clinton, implicitly referring to a tweet in which Trump claimed that global warming “was created by the Chinese” to benefit their manufacturing sector. “I think it’s real. And I think it’s important that we grip this and deal with it, both at home and abroad.”
Politifact reports that although Trump indicated the 2012 tweet was a joke, he has a record of using the word “hoax” to describe climate change, especially on Twitter. CNN reported that in September 2015 Trump told its reporters that “I am not a believer in climate change” and that he refuted climate change’s role in the rise in extreme weather phenomena.
On energy, Trump said he favors all forms of energy, but he noted that coal industry workers have been put out of work by cheap natural gas and federal environmental regulations. Clinton, on the other hand, suggested that clean energy could be an important job creator.
“We can deploy a half a billion more solar panels,” she said. “We can have enough clean energy to power every home. We can build a new modern electric grid. That’s a lot of jobs. That’s a lot of new economic activity.”
Trump responded with an implicit reference to the 2011 bankruptcy of the federally backed solar company Solyndra.
“She talks about solar panels,” replied Trump. “We invested in a solar company, our country. That was a disaster. They lost plenty of money on that one. … Now, look, I’m a great believer in all forms of energy, but we’re putting a lot of people out of work. Our energy policies are a disaster.”
Fortune reports that Department of Energy figures show that the loan program that funded Solyndra has created thousands of jobs and that taxpayers have profited from that program because the vast majority of its other loans went to successful projects and companies.
Climate Change and National Security
Climate change will have significant effects on national security, according to a new report by the Office of the Director of National Intelligence. It says these threats are wide-ranging—including adverse effects on food prices and availability, country stability, increased risk to human health, and heightened social and political tensions—and that these threats could affect the United States and other countries over the next 20 years.
“We’re already beginning to see the devastating effects of weather-related disasters, drought, famine, and damaged infrastructure on communities around the world,” Secretary of State John Kerry said in a statement. “Add to that an increased risk of conflict over water and land, and the large-scale displacement due to rising sea levels, and it’s not hard to see why the Pentagon has deemed climate change a ‘threat-multiplier,’ exacerbating the pressures and challenges far too many countries are already facing.”
The release of the report comes as the White House announced a new policy framework requiring federal agencies to take the impacts of climate change into account when making national security-related policies and plans. It directs several federal agencies to work together to include climate change in their national security planning—providing a timeline of 90 days to create an action plan and 150 days to create a plan to implement it.
Surveys conducted by Yale University and George Mason University suggest that 17 percent of Americans view climate change as an alarming threat and that another 28 percent are concerned about climate change but view it as a distant threat.
The subject has become highly contentious since 1997, when then Vice President Gore helped broker an international treaty, the Kyoto Protocol, to reduce heat-trapping gases from the burning of coal, oil and gas. The U.S. later withdrew from the treaty.
“And at that moment the two parties began to divide,” said Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, who was involved in the surveys. “They begin to split and go farther and farther and farther apart until we reach today’s environment where climate change is now one of the most polarized issues in America.”
Climate change will again be in the spotlight as a group of climate scientists gather in Switzerland to discuss a United Nation’s report expected to detail the impacts of 1.5 degrees Celsius of warming. In Paris last year, some 190 countries pledged to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. But there are scientific questions not only about the costs and benefits of keeping warming to 1.5 degrees Celsius, but also about how to remain on a 1.5 C pathway. The Huffington Post shows what the Paris Climate Agreement is up against in a series of charts.
What we do know is this decade is the critical decade for action.
“The risks of future climate change—to our economy, society and environment—are serious, and grow rapidly with each degree of further temperature rise,” the Australian government’s Climate Commission wrote in a report. “Minimising these risks requires rapid, deep and ongoing reductions to global greenhouse gas emissions. We must begin now if we are to decarbonize our economy and move to clean energy sources by 2050. This decade is the critical decade.”
And the Host City of the Summer 2084 Games Is . . .
A study published in The Lancet says that only three North American cities—San Francisco, Calgary, Vancouver—will have a climate sufficiently cool and stable to host the Summer Olympic games in 70 years. The authors, who considered only cities in the northern hemisphere, where 90 percent of the world’s population lives, and only those with a population greater than 600,000 in 2012, the lower limit of host cities since World War II, said that climate change would make most of the 645 cities unsafe venues due to rising temperatures and humidity caused by climate change.
“You could take a risk, and plan your Olympics, and maybe not get the hot days you expect, but that would be a big risk when there are many billions of dollars at stake,” said Kirk Smith, a researcher at the University of California–Berkeley’s School of Public Health and the lead author of the study.
To measure the suitability of future Olympics sites, the researchers used climate change projections and a “wetbulb” globe temperature—a measurement reflecting the combination of humidity, heat radiation, temperature, and wind. They picked 2085 as a target date and as their target event what they considered the Olympics’ most physically challenging outdoor endurance event: the marathon. They selected 82.5 degrees Fahrenheit as the “high-risk” temperature for marathoners.
“The findings indicate that by 2085, Istanbul, Madrid, Rome, Paris and Budapest—all cities that are or were in contention for either the 2020 or 2024 Summer Olympics—would be unfit to host the games,” the authors said. “Tokyo, the city that has secured the 2020 summer Olympiad, would also be too hot to ensure athlete safety, should these projections come to pass.”
Which cities would be viable hosts? None in Latin America or Africa, 25 in western Europe, 5 in eastern Europe and Asia, and 3 in North America.
“If the world’s most elite athletes need to be protected from climate change, what about the rest of us?” the study concludes.
One of the most startling implications of the research is that temperatures will be too high for laboring outdoors, where half the world’s population works.
Truck Emissions Limits Set
New emissions requirements affecting heavy- and medium-duty vehicles, which represent only about 5 percent of total highway traffic but account for 20 percent of transportation-related fuel consumption and carbon emissions, were announced this week. The requirements call for as much as a 25 percent reduction in carbon emissions and fuel consumption in certain models by 2027. It also requires annual increases in efficiency of 2.5% from 2021-2027 for heavy-duty pickup trucks and vans.
“The standards promote a new generation of cleaner, more fuel-efficient trucks by encouraging the development and employment of new and advanced cost-effective technologies through model year 2027,” said Gina McCarthy, administrator of the U.S. Environmental Protection Agency (EPA), which developed the new rules in conjunction with the National Highway Traffic Safety Administration. “These standards are ambitious and achievable, and they will help ensure the American trucking industry continues to drive our economy — and at the same time protect our planet.”
Official say the new requirements are expected to cut 1.1 billion metric tons of carbon emissions through the next decade and represent a global benchmark for reducing vehicle-exhaust pollutants linked to climate change.
By 2030, half of the energy produced in the state of New York will come from renewables, according to a new policy adopted Monday by the state’s public service commission. The move is expected to reduce greenhouse gas emissions by 40 percent from 1990 levels (80 percent by 2050) and to attract billions in clean energy investment.
“New York has taken bold action to become a national leader in the clean energy economy and is taking concrete, cost-effective steps today to safeguard this state’s environment for decades to come,” said New York Gov. Andrew Cuomo. “This Clean Energy Standard shows you can generate the power necessary for supporting the modern economy while combatting climate change. Make no mistake, this is a very real threat that continues to grow by the day and I urge all other states to join us in this fight for our very future.”
The plan calls for New York to retain its nuclear reactors—though The Washington Post reports that those facilities don’t count as part of the 50 percent renewables target. According to New York regulators, doing so might cost $965 million over two years but could lead to net benefits of $4 billion due to avoided carbon dioxide emissions and air pollution. While supporters of this provision applaud New York’s effort to retain its emissions-free nuclear generation, opponents are likely to challenge the nuclear subsidies on the grounds they are discriminatory, hurt markets, and intrude on federal authority.
New York is not the first state to announce an ambitious greenhouse gas reduction target. In April 2015, California announced it planned to cut those emissions by 40 percent below 1990 levels in the same time frame with renewables increases. Like California, New York plans to phase in its renewables increase; 31 percent of its energy is to come from renewables by 2021 and 50 percent by 2030. Those targets are meant to give utilities and clean energy companies time to develop their business models.
White House to Federal Agencies: Consider Climate Change Impacts
In an action with broad implications for thousands of projects, including energy and mineral development on public lands, natural gas import and export facilities, and transportation projects, the Obama administration issued final guidance on how federal agencies should consider greenhouse gas emissions and climate change impacts when conducting reviews under the National Environmental Policy Act (NEPA) (subscription).
“Focused and effective consideration of climate change in NEPA reviews will allow agencies to improve the quality of their decisions,” the guidance states. “Identifying important interactions between a changing climate and the environmental impacts from a proposed action can help Federal agencies and other decision makers identify practicable opportunities to reduce greenhouse gas emissions, improve environmental outcomes, and contribute to safeguarding communities and their infrastructure against the effects of extreme weather events and other climate-related impacts.”
The guidance, the product of a six-year effort by the White House Council on Environmental Quality, advises agencies to quantify projected greenhouse gas emissions of proposed federal actions whenever the necessary methodologies and data are available. It also encourages them to draw on their experience and expertise to determine the appropriate level and extent of quantitative or qualitative analysis required to comply with NEPA and to consider alternatives that would increase the climate-change resilience of the action and affected communities.
“From the public standpoint, we are now going to know what all of our decisions add up to in terms of impacting climate change,” said Christy Goldfuss, managing director of the Council on Environmental Quality. “You can think of all the different federal decisions, and how they all add up. We have numbers where we can actually say, ‘this is a huge decision, given the amount of greenhouse gases coming out of it.’ And that gives the public a chance to really weigh in on decision-making.”
Several media outlets pointed out that because the White House guidance is not a regulation, agencies are not legally bound to follow it.
Clean Power Plan Analysis: National Costs Low, State Costs Varied
Wednesday marked one year since the U.S. Environmental Protection Agency formally rolled out the Clean Power Plan, which aims to reduce carbon emissions from power plants. Even with the February stay by the U.S. Supreme Court, which halted implementation of the plan pending resolution of legal challenges, some say the plan is having an impact while others are finding more reason to explore the legality of the rule (subscription).
Should the rule survive judicial review, a new paper by the Nicholas Institute for Environmental Policy Solutions uses the Nicholas Institute’s Dynamic Integrated Economy/Energy/Emissions Model to evaluate Clean Power Plan impacts on the U.S. generation mix, emissions, and industry costs. It indicates that industry trends are likely to make Clean Power Plan compliance relatively inexpensive, with cost increases of 0.1 to 1.0 percent. But policy costs can vary across states, which might lead to a patchwork of policies that, although in their own best interests, could impose additional costs nationally.
“The answer is not the same for everyone in terms of what’s going to be the least-cost way for a particular state to approach this policy,” said lead author and Nicholas Institute Senior Economist Martin Ross. “Nationally, it would make the most sense to have a broadly coordinated policy where you can take advantage of the usual economic [tools] to spread the cost reductions around and pick up the most cost-effective sources for reducing emissions.”
Similar findings were presented at a conference of the National Association of Regulatory Utility Commissioners. Because of lower-than-expected natural gas prices, renewable power, and extended federal tax credits for that power, the country as a whole is set to meet the Clean Power Plan’s early goals, reports ClimateWire.
In March, the Guardian issued an election-related call-out to online readers in the United States, asking them to identify the “one issue that affects your life you wish the presidential candidates were discussing more.” The results are in. Of the 1,385 respondents from all 50 states, one in five expressed discontent about lack of discussion of climate change, an issue described in vivid terms, such as “cataclysmic” and “slow-motion apocalypse.” Respondents expressed greatest concern about sea-level rise and decreasing food and water security.
“Climate change is the common denominator for us all regardless of gender, creed or political affiliation,” said Sarah Owen in a video response to the survey.
Between parties, there’s divide on the topic of climate change. Eleven House Republicans who are trying to change their party’s attitude about climate change and four of five Republican senators with a record of supporting action on it skipped this week’s GOP convention, where delegates approved a party platform that rejected the Paris Agreement, a carbon tax, and other action on climate change and that downplayed use of renewable energy.
“Climate change is far from this nation’s most pressing national security issue. This is the triumph of extremism over common sense, and Congress must stop it,” reads the platform.
Just how ambitious the Democratic Party will be in attempting to reduce carbon emissions—particularly, its stance on a carbon tax—remains to be seen. The full platform committee will hammer out details in Orlando on Friday and Saturday.
In an interview with ClimateWire, U.S. Special Envoy for Climate Change Jonathan Pershing suggested that the U.S. presidential election will have less impact on American efforts to combat climate change than a host of other factors ranging from new technologies and appliance standards to political support for renewable energy tax credits.
“To me, there’s more likely to be continuity no matter who’s in office,” Pershing said.
Projecting Clean Power Plan Costs, Impacts
The Clean Power Plan aims to reduce carbon emissions from existing power plants. Assuming the rule survives judicial review and is implemented, the U.S. Energy Information Administration (EIA) projects a reduction of power sector emissions of about 35 percent by 2030.
Assuming the Clean Power plan is upheld, EIA projects emissions outcome and electricity generation mix for multiple state implementation strategies—that is, pursuit of mass-based emissions targets or rate-based emissions targets. EIA projects higher prices if emissions allocations under a mass-based regime are given to generators rather than load-serving entities, but “price effects are similar in the [mass] and CPP rate cases where the average electricity price from 2022 through 2030 in both cases is 2 percent higher than in the No CPP case, and 3 percent higher on average from 2030 through 2040,” analysts wrote.
As the EIA data suggests, utilities and other power producers are likely to be in different positions if the rule moves forward—some will benefit from the rule, and others will face costs to comply, which can lead to monetary transfers among different producers and consumers of electricity. A new policy brief by Duke University’s Nicholas Institute for Environmental Policy Solutions builds on this understanding by exploring the distributional impacts of choosing rate-based and mass-based approaches to comply with the Clean Power Plan. It finds that states adopting a mass-based compliance approach can use allowance allocation to largely control monetary transfers within a state. States adopting a rate-based compliance approach lack this direct control mechanism.
Each state’s system of electricity regulation and any changes in wholesale prices for electricity due to the policy in regional electricity markets will play a major role in determining how cost distribution and potential transfers play out, the authors said.
Study: Warm Water, Not Air, Accelerating Glacier Retreat on Western Antarctic Peninsula
A study published in the journal Science found that ocean warming, rather than atmospheric warming, is the primary cause of retreat of 90 percent of the 674 glaciers on the western Antarctic Peninsula. Because the peninsula’s glaciers are among the main contributors to sea-level rise, the study suggests that better understanding of how and why they’re changing will increase the accuracy of ice-loss predictions.
“Scientists know that ocean warming is affecting large glaciers elsewhere on the continent, but thought that atmospheric temperatures were the primary cause of all glacier changes on the Peninsula,” said lead author Alison Cook of Swansea University. “We now know that’s not the case.”
The scientists came to that conclusion after linking a distinct pattern of melt from north to south on the peninsula with a pattern of temperatures at mid-ocean depths that mirrored the melt. At the southern end of the western side of the peninsula, they found that a welling up of warm Circumpolar Deep Water wears away the fronts of glaciers. At the northern end of the peninsula, the fronts of glaciers are more stable because they terminate at colder waters that come from a different source.
“Our results are key for making predictions of ice loss in response to ocean warming in this region,” Cook said. “The Antarctic Peninsula is one of the largest current contributors to sea-level rise, and the glaciers here are highly sensitive, so [they] are key indicators of how the ice will respond to future changes.”
Just weeks before the U.S. Court of Appeals for the D.C. Circuit was scheduled to hear challenges to the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan, a rule intended to limit greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants, the court announced it will push the hearing back four months and hear the case before the entire court.
Originally planned for June 2 before a three-judge panel, the hearing was postponed to Sept. 27 and will now take place in front of a full bench. The rare “en banc” review is allowed by procedural rules when the case involves a question of exceptional importance. According to The Washington Post, the decision to pursue such a review appears to be on the court’s own initiative. The move to skip the customary three-panel review, as was the case in 2001’s U.S. v. Microsoft, is almost unheard of and could signal that the judges feel the issues of the case are so significant that they all must weigh in.
“The court has anticipated, obviously, the significance of whatever the panel would say and the related likelihood that it would end up en banc. They’ve basically truncated that process,” Richard Lazarus, a Harvard Law School professor, told Bloomberg BNA.
The order follows an announcement by the D.C. Circuit last year that it would hear the Clean Power Plan on an expedited schedule and a stay on implementation of the plan in February by the U.S. Supreme Court while the lower court determines its legality.
Even so, some indicate the change may actually speed up the final resolution of the case.
“It definitely shortens the time period for this to get to the Supreme Court,” said Dorsey & Whitney Attorney James Rubin (subscription). “This does show that there is recognition for the need to move this forward. It’ll speed things up to some extent.”
EPA Targets Oil and Gas Industry Methane Emissions
The EPA has taken the first-ever steps under the Clean Air Act to regulate oil and gas industry emissions of methane, announcing a new rule aimed at new or modified oil and natural gas wells. The EPA said the regulations, which the EPA proposed last year, would lower methane emissions by 510,000 short tons—the equivalent of 11 million metric tons of carbon dioxide—in 2025, the year by which the Obama administration’s goal is to reduce the sector’s methane emissions by at least 40 percent compared with 2012 levels.
The rules will require energy companies to provide pollution information to the EPA so it can regulate methane emissions from existing oil and gas wells.
To begin regulating methane leaks from existing oil and gas wells, the EPA is requiring energy companies to notify the agency about their emissions and leak-stopping technology. The information request is expected to be finalized later this year and data collection from the industry, early next year.
According to the EPA, pound for pound, the impact of methane on climate change is “more than 25 times greater than carbon dioxide over a 100-year period.”
Climate Negotiators Meet in Germany to Make Implementation Plan for Paris Agreement
Climate negotiators met in Bonn, Germany, for the first official meeting of the United Nations Framework Convention on Climate Change since the Paris Agreement last year.
A note to Bonn participants stresses the importance of shifting from negotiation to implementation of the landmark agreement—whereby more than 190 countries pledged to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. More than 175 countries have signed the agreement.
The challenge ahead, writes French Environment Minister Segolene Royal and Morocco’s Foreign Prime Minister Salaheddine Mezouar, the previous Paris COP21 president and incoming COP22 president, is to “operationalize the Paris agreement: to turn intended nationally determined contributions into public policies and investment plans for mitigation and adaptation and to deliver on our promises.”
The two-week meeting is expected to produce an agenda for the ad-hoc working group tasked with implementing the Paris Agreement.
Addressing delegates at the start of the meeting, retiring U.N. climate director Christiana Figueres said “The whole world is united in its commitment to the global goals embodied in the Paris Agreement. Now we must design the details of the path to the safe, prosperous and climate-neutral future to which we all aspire.”
Last week more than 150 nations signed the Paris Agreement, pledging to hold the increase in the global average temperature to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. Now, the first comprehensive analysis of the impacts of that half centigrade difference has been published in the journal Earth System Dynamics. The scientists found the additional 0.5 degrees Celsius would lead to longer heatwaves—“the difference between events at the upper limit of present-day natural variability and a new climate regime”—as well as more severe droughts and, in the tropics, decreased crop yield and the potential demise of all coral reefs. The extra 0.5 degrees Celsius could also mean that global sea levels rise 10 centimeters more by 2100.
“We found significant differences for all the impacts we considered,” says the study’s lead author Carl Schleussner, a scientific advisor at Climate Analytics in Germany.
The researchers analyzed climate models used in the Intergovernmental Panel on Climate Change Fifth Assessment Report, which focused on the projected regional impacts of 1.5 degrees Celsius and 2 degrees Celsius of warming, and considered 11 indicators, including extreme weather events, water availability, crop yields, coral reef degradation and sea-level rise.
They found that projected climate impacts at a 2 degrees Celsius increase are significantly more severe than at a 1.5 degrees Celsius increase in some regions. In the Mediterranean, for example, fresh-water availability by 2100 would be some 10 percent lower in a 1.5 degrees Celsius world and 17 percent lower in a 2 degrees Celsius world. In Central America and West Africa, the half-degree difference could reduce maize and wheat yields by twice as much. Tropical regions would bear the brunt of the impacts of an additional half degree of warming, experiencing heat waves at about twice the global rate. Those events could last up to three months at 2 degrees Celsius, compared with two months at 1.5 degrees Celsius, the researchers say.
Tropical coral reefs are particularly sensitive to the half degree increase. By 2100, some reefs might adapt to 1.5 degrees Celsius of warming, but the larger increase would put nearly all of them at risk of severe degradation from coral bleaching.
EPA Moves Forward with Clean Energy Incentives Program
The U.S. Environmental Protection Agency (EPA) has sent a proposal on the Clean Energy Incentive Program (CEIP), an optional program included in the Clean Power Plan that rewards states for early investment in certain renewable energy or energy efficiency projects in 2020 and 2021, to the Office of Management and Budget for review. The move is the final step before the CEIP can be formally proposed to the public (subscription).
The EPA released details on the draft CEIP as part of the final Clean Power Plan—the Obama administration’s rule to limit greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants—in August. But, earlier this year, the Supreme Court issued a stay of the Clean Power Plan.
“Many states and tribes have indicated that they plan to move forward voluntarily to work to cut carbon pollution from power plants and have asked the agency to continue providing support and developing tools that may support those efforts, including the CEIP,” the EPA said. “Sending this proposal to OMB for review is a routine step and it is consistent with the Supreme Court stay of the Clean Power Plan.”
Pleasant Weather Affecting Americans’ View of Climate Change
A new study in the journal Nature finds that 80 percent of Americans live in counties where the weather is more pleasant than four decades ago. This mild temperature trend, the study says, is increasingly preferred, lessening many Americans’ concern about climate change.
“Rising temperatures are ominous symptoms of global climate change, but Americans are experiencing them at times of the year when warmer days are welcomed,” said study co-author Patrick J. Egan, an associate professor at New York University’s Wilf Family Department of Politics. He adds that “whereas weather patterns in recent decades have served as a poor source of motivation for Americans to demand a policy response to climate change, public concern may rise once people’s everyday experiences of climate change effects start to become less pleasant.”
Conducted by New York and Duke universities, the study examined each county in every U.S. state from 1974 to 2013—assessing the mildness of winters, rainfall averages, and humidity and heat intensity during summer months. It found that 99 percent of Americans live in places where the average January temperature increased.
“Here in the U.S., when we’re experiencing ice storms, the idea of a 1.5 or 2 degree rise might sound like good news,” said Megan Mullin, associate professor of environmental politics at Duke University. As a result, she said, scientists need to reconsider their messages.
Four months after it was finalized by delegates to the Paris Climate Change Conference, the Paris Agreement will be signed by more than 100 nations on Friday. While the agreement is facially insufficient to meet its overall emissions objectives, the signing of the Paris agreement nevertheless is significant. It brings into effect the approach and policy infrastructure needed to tackle the United Nations Framework Convention on Climate Change’s ambitious goal to minimize human-caused climate change. The agreement does not solve the problem on its own, but it is a structured revisitation of the science and national commitments that provide the adaptive approach necessary to reach a solution. It is now on researchers and entrepreneurs to invent solutions; for governments, development banks and the private sector to deploy them; and for nations to hold each other accountable as this agreement goes into effect.
Energy innovation is just one of the benefits of the signing, according to White House Press Secretary Josh Earnest.
“This will open up a market for energy innovation that U.S. companies have pioneered,” Earnest said. “This is going to open up a global market for the kind of renewable energy technology that U.S. companies are at the cutting edge of.”
Other shifts have occurred since the Paris Agreement was finalized, GreenBiz reports. Big companies have backed the Clean Power Plan, there’s a rise in “sub-national” climate action at the state and city level and President Obama has proposed $10-a-barrel-tax on oil, they say.
EPA Finds Benefits Outweigh Cost of Mercury Rule
Benefits of the Mercury and Air Toxics Standard (MATS) rule outweigh cost, the U.S. Environmental Protection Agency (EPA) said in findings released in defense of its issuance of the first-ever federal regulations requiring power plants to cut mercury emissions and other toxics.
The Supreme Court found, last year, that the EPA should have considered compliance costs when determining whether it was “appropriate and necessary” to regulate mercury emissions from the power sector. In a June ruling, it did not strike down the regulation; rather, it required the EPA to take costs into consideration.
In its final 167-page report on the matter, now awaiting publication in the Federal Register, the EPA details how it considered cost in evaluating whether to regulate coal-and oil-fired power plants under the Clean Air Act (subscription).
“Based on this analysis, EPA has determined that the cost of complying with MATS, whether assessed as a percentage of total capital expenditures, percentage of power sector sales, or predicted impact on the retail price of electricity, is reasonable and that the electric power industry can comply with MATS and maintain its ability to provide reliable electric power to consumers at a reasonable cost,” the EPA wrote.
The annual cost of complying with MATS, the EPA found, amounts to between 2.7 and 3.5 percent of electricity sales, and the capital costs between 3 and 5.9 percent of annual power sector capital expenditures over 10 years.
Methane Emissions Greater Than Thought
In its newly released annual greenhouse gas emissions inventory, the EPA raised its estimate of total U.S. methane emissions in 2013 by 13 percent—an increase of more than 3.4 million metric tons and a long-term global warming impact of a year’s worth of emissions from some 20 million cars, Science News reported. The agency’s first estimate of methane emissions for 2014 is even higher, although only slightly so—29.233 million metric tons compared with 28.859 million metric tons.
Although there was a roughly 1 percent increase in total U.S. greenhouse gas emissions between 2013 and 2014, the inventory shows 2014 levels were 8.6 percent lower than 2005 levels, taking into account carbon sinks (subscription).
According to the EPA, the biggest methane emitter is the oil and natural gas industry—not animals like cattle and other livestock, as had been suggested by last year’s inventory. The data in this latest inventory are based on new techniques for estimating methane leaking from valves, compressors, vents, and other oil and gas equipment.
