Editor’s Note: The Climate Post will not circulate Thursday, December 29, in honor of the New Year’s Holiday. It will return January 5.

Invoking the so-called 12(a) provision of the 1953 Outer Continental Shelf Lands Act, President Obama announced a permanent ban on offshore oil and gas drilling in more than 100 million acres of the Atlantic and Arctic. The ban affects oil and gas drilling in the Chukchi Sea and most of the Beaufort Sea off Alaska as well as in a stretch of the Atlantic Ocean from New England to Virginia. The announcement was made in conjunction with one by Canadian Prime Minister Justin Trudeau, who also put a freeze on leasing, agreeing to make Canada’s Arctic waters free of drilling—a policy subject to review every five years.

“These actions, and Canada’s parallel actions, protect a sensitive and unique ecosystem that is unlike any other region on earth,” Obama said. “They reflect the scientific assessment that, even with the high safety standards that both our countries have put in place, the risks of an oil spill in this region are significant and our ability to clean up from a spill in the region’s harsh conditions is limited. By contrast, it would take decades to fully develop the production infrastructure necessary for any large-scale oil and gas leasing production in the region—at a time when we need to continue to move decisively away from fossil fuels.”

He cited the region’s low contribution to U.S. energy as a reason for the ban.

“In 2015, just 0.1 percent of U.S. federal offshore crude production came from the Arctic and Department of Interior analysis shows that, at current oil prices, significant production in the Arctic will not occur,” Obama said.

Politico reports that Section 12(a) of the Outer Continental Shelf Lands Act includes no language that allows future presidents to undo the withdrawal of offshore areas from future leasing but fossil fuel advocates will likely argue that sufficient precedent exists for Trump to reverse the ban.

EPA Releases Drafts of Model Rules for Clean Power Plan

The U.S. Environmental Protection Agency (EPA) on Monday withdrew its draft proposed model rules for the Clean Power Plan from interagency review. The rules were an optional template for state implementation plans, designed to make it easier for states and power plants to use emissions trading to meet the Clean Power  Plan carbon reduction goals.

“While these drafts are not final and we are not required to release them at this time, making them available now allows us to share our work to date and to respond to the states that have requested information prior to the end of the Administration,” said Janet McCabe, acting assistant administrator for the EPA’s Office of Air and Radiation in a blog post. “We believe that the work we have done so far may be useful at this time to the states, stakeholders and members of the public who are considering or are already implementing policies and programs that would cut carbon pollution from the power sector.”

The drafts, released in response to multiple requests from states, describe how states might use a mass- or rate-based emissions scheme under the Clean Power Plan. They will not be published in the Federal Register, and they carry no legal authority.

The Clean Power Plan is presently stayed while a ten-judge panel reviews a legal challenge. A decision from the D.C. Circuit Court of Appeals’ rare “en banc” review is expected next year.

Report: Human-Caused Climate Change Intensified Some Extreme Weather Events in 2015

A report published by the American Meteorological Society links man-made climate change to 24 extreme weather events in 2015. The events include wildfires in Alaska, heavy rains in China, and droughts in Ethiopia. According to the report, which examined 30 events, climate change worsened 10 of last year’s deadly heat waves, three of which killed thousands of people in Egypt, India, and Pakistan.

“Without exception, all the heat-related events studied … were found to have been made more intense or likely due to human-induced climate change,” said the report compiled by 116 scientists from 18 countries using calculations based on observed data, computer simulations, and climate physics.

The study reflects an emerging area of climate research—one based on scientists’ prediction that climate change would affect the severity and frequency of extreme weather events and one that seeks to identify the likelihood that any given event was influenced by climate change.

“We do this for the same reasons we’ve always tried to understand our weather,” said Stephanie Herring, a scientist at the National Oceanic and Atmospheric Administration and lead editor of the new report. “We know if we can better understand why these events are happening, we can better predict and prepare for them in the future.”

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).

Clean Power Plan Goes to Court

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.

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.

The only states with higher renewables standards are Vermont, which set a target of 75 percent renewable power by 2032, and Hawaii, which set a target of 100 percent renewable power by 2045.

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.

In resisting aggressive climate action, the Republican platform stands in stark contrast to the draft Democratic Party platform, which calls for more regulations and laws to fight climate change.

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.

Pershing indicted that many U.S. steps to curb greenhouse gas emissions, including the Paris climate change deal negotiated under President Obama, will survive no matter who wins the White House.

“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.”

Study: Half a Degree Matters

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.

The outlook for 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, is the subject of debate after two key Supreme Court events last week.

First, on Tuesday, the U.S. Supreme Court in a 5–4 decision issued a stay, delaying the execution of the plan, pending the outcome of legal challenges. The New York Times called the decision “unprecedented,” because the Supreme Court had never before granted a request to halt a regulation before review by a federal appeals court. At a minimum, the ruling will allow states to skip the September deadline to submit compliance plans to the EPA.

A new twist on the fate of the Clean Power Plan came Saturday with the death of Supreme Court Justice Antonin Scalia—leaving the Supreme Court with eight justices split evenly between conservatives and liberals, and evenly split on the question of that week’s stay. Whether the White House or the Senate will confirm a new justice before the November 2016 Presidential election remains unclear, although political cynicism about any nominee’s chances has dominated commentary. President Obama announced plans to nominate a new justice, and Senate Republican leadership has indicated that it does not intend to confirm Obama’s candidate.

The D.C. Circuit is set to begin hearing oral arguments challenging the Clean Power Plan in June. Any ruling may be reviewed by the Supreme Court.

ClimateWire suggests three potential scenarios. For Clean Power Plan opponents, the best turn of events would be appointment of a new conservative-leaning justice, which would be made possible if the Senate successfully blocks an Obama appointee and a Republican takes the White House. Those in favor of the plan would benefit from appointment of a new liberal-leaning justice or from the court’s consideration of the plan before a new justice is confirmed.

Politics surrounding the nomination of the new justice are complicated, writes Tom Goldstein of the SCOTUS blog.

Study: More Aggressive Emissions Reductions Needed to Curb Air-Pollution-Related Deaths

A new study undertaken by the World Health Organization and presented last week at the annual meeting of the American Association for the Advancement of Science shows that 5.5 million die prematurely every year from air pollution. The authors—a team of U.S., Canadian, Chinese, and Indian scientists—said that most of the fatalities are in India and in China, where coal burning alone led to 366,000 deaths in 2013.

Researcher Qiao Ma from Tsinghua University in Beijing said coal burned for electricity was the largest polluter in China and that the country’s new targets to reduce emissions, agreed at last year’s Paris climate talks, are not sufficiently ambitious to end those deaths.

“Even in the most clean scenario in 2030,” Ma said, China’s growing and aging population will still suffer as many as 1.3 million deaths a year. “Our study highlights the urgent need for even more aggressive strategies to reduce emissions from coal and from other sectors.”

Although China halted approval of new coal mines for three years at the end of 2015 and has issued stringent requirements similar to those recently proposed in the United States for new coal-fired power plants, these and other measures may not halt increases in mortality, reported Time.

“Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease,” said Michael Brauer of the University of British Columbia. “Reducing air pollution is an incredibly efficient way to improve the health of a population.”

Agreements Made to Expand Renewables, Reduce Emissions

Governors from 17 U.S. states signed an accord to diversify energy generation with clean energy sources, modernize their energy infrastructure and encourage clean transportation options. Home to about 40 percent of the country’s population, states signing the Governors’ Accord for a New Energy Future are California, Connecticut, Delaware, Hawaii, Iowa, Massachusetts, Michigan, Minnesota, New Hampshire, Nevada, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia and Washington.

“With this agreement, governors from both parties have joined together and committed themselves to a clean energy future,” said California Gov. Jerry Brown. “Our goal is to clean up the air and protect our natural resources.”

As part of the agreement, states will cooperate on planning and policies—pooling buying power to get cheaper clean-energy vehicles for state fleets and to build more energy-efficient regional electrical grids.

Also preparing for a cleaner-energy future is Fiji, which on Friday became the first country to formally approve the United Nations climate deal reached in Paris when its parliament ratified the agreement. Under its national climate action plan, the archipelago, which is vulnerable to flooding and strong tropical storms as a result of climate change, pledged to generate all its electricity from renewable sources by 2030 and to reduce its overall energy-sector emissions by 30 percent by 2030—if it receives climate finance from industrialized nations.

Supreme Court Suspends Clean Power Plan

The U.S. Supreme Court blocked the Clean Power Plan, the U.S. Environmental Protection Agency’s rule limiting greenhouse gas emissions from the existing fleet of fossil fuel-fired power plants on Tuesday. The court, in a 5–4 decision split along party lines, put a stay on enforcement of the Clean Power Plan, which is designed to cut carbon dioxide emissions from power plants 32 percent below 2005 levels by 2030.

“We remain confident that we will prevail on the merits,” said the White House in a statement. “Even while the litigation proceeds, EPA has indicated it will work with states that choose to continue plan development and will prepare the tools those states will need.”

But others felt the move could be indicative that the Clean Power Plan will not survive legal scrutiny.

“Should the D.C. Circuit uphold the rule, I think the stay is indicative that the court is likely to want to hear this case,” said Scott Segal, a partner in Bracewell LPP’s Policy Resolution Group. “Even the most ardent supporters would have to concede that this does not bode well for the current rule.”

The EPA’s authority to regulate greenhouse gas emissions stems from the 2007 Supreme Court decision Massachusetts v. EPA, which found that carbon dioxide qualified as a “pollutant” and was subject to regulation under the Clean Air Act. But Bloomberg reported that the court’s intervention casts doubt on the legal prospects for the Clean Power Plan, which some utilities, coal miners and more than two dozen states are challenging as an overreach of the U.S. Environmental Protection Agency’s authority and an intrusion on states’ rights. The D.C. Circuit Court will review the merits of their lawsuits on June 2. The order blocks the Clean Power Plan from taking effect while legal battles play out, making a decision possibly another year or more away.

“A decision overturning the Clean Power Plan would not prevent the EPA from regulating greenhouse gas emissions under the Clean Air Act,” said Jonas Monast, director of the Climate and Energy Program at Duke’s Nicholas Institute for Environmental Policy Solutions. “That case focuses on current regulations. It does not call into questions the Supreme Court’s previous finding that greenhouse gases are pollutants under the Clean Air Act.”

De-carbonization of U.S. Power Sector Accelerated in 2015

Energy sector transitions envisioned by the U.S. Environmental Protection Agency (EPA) when it released its Clean Power Plan last year are already occurring at a faster pace than the EPA may have expected as evidenced by Bloomberg New Energy Finance’s  (BNEF) 2016 Sustainable Energy in America Factbook, which called 2015 a “watershed year in the evolution of US energy.”

According to the report, coal use for electricity generation dropped from 39 percent in 2014 to 34 percent last year, while natural gas edged closer to becoming the largest source of U.S. power, accounting for some 32 percent of U.S. generation in 2015. Along with energy efficiency improvements, notable growth in renewable energy installations, and flat energy demand, that shift has major implications for greenhouse gas emissions reductions but not for consumer costs—at least so far.

“We saw natural gas and coal each provide about one third of U.S. electricity, and this was the smallest contribution we’ve seen from coal within the modern era,” said Colleen Regan, BNEF’s senior analyst for North American power. She noted that the decrease in coal use was attributable not only to cheap gas but also to 14 gigawatts’ worth of coal plant retirements—5 percent of U.S. coal capacity—last year.

Meanwhile, the U.S. renewable energy industry brought online 16 gigawatts of clean energy—68 percent of all new installed capacity—helping drop U.S. energy sector carbon dioxide emissions to their lowest annual level since the mid-1990s in a year that saw retail electric rates fall 1.3 percent in real terms from 2014.

Driving what the report authors suggest is a permanent shift in the U.S. energy sector are technological revolutions in the gas industry, increasingly attractive economics for renewables, and international- and national-level policy directives, including the Clean Power Plan and recent extensions of the investment tax credit for solar power and the production tax credit for wind energy (subscription).

Next Few Decades’ Emissions Trajectory Could Affect Earth for Millennia

A group of 22 researchers, including several of the world’s foremost climate scientists, contend that we have been thinking about climate change far too narrowly by making projections only to the year 2100. In a study published in Nature Climate Change, the group suggests that policy makers should consider the consequences of human emissions on global temperatures and sea level over a far longer time horizon.

“The twentieth and twenty-first centuries, a period during which the overwhelming majority of human-caused carbon emissions are likely to occur, need to be placed into a long-term context that includes the past 20 millennia, when the last Ice Age ended and human civilization developed, and the next ten millennia, over which time the projected impacts of anthropogenic climate change will grow and persist,” they write. “This long-term perspective illustrates that policy decisions made in the next few years to decades will have profound impacts on global climate, ecosystems and human societies—not just for this century, but for the next ten millennia and beyond.”

The study, which looked at climate data from the past 20,000 years and four emissions scenarios for the period 2000 to 2300, demonstrates the effects of near-term policy decisions on the climate system’s inherent lag effects—namely, the high temperature sensitivity of global ice sheets and the centuries-long atmospheric retention of carbon dioxide.

“If carbon dioxide emissions continue unchecked, the carbon dioxide released during this century will commit Earth and its residents to an entirely new climate regime,” the study says.

Report co-author, Thomas Stocker, a climate scientist at the University of Bern, put the long-term view of human emissions bluntly, saying that it sends a “chilling message” about the fossil fuel era’s risks and consequences. “It will commit us to massive adaptation efforts so that for many, dislocation and migration becomes the only option.” The study notes that even if warming falls below the United Nations target of 2 degrees Celsius, 20 percent of the world’s population must migrate away from coasts.

A new study in the journal Nature Climate Change suggests that climate-change-related water disruptions could significantly decrease electricity production by the hydropower stations and thermoelectric (nuclear, fossil-fueled, biomass-fueled) plants that account for 98 percent of production around the world. Because the plants need water to cool generators and pump power at dams, they are vulnerable to lower river levels and warmer water temperatures, according to researchers at Wageningen University and the International Institute for Applied Systems Analysis (IIASA). These conditions could reduce generating capacity by as much as 74 percent in hydro plants and 86 percent in thermoelectric plants between 2040 and 2069.

“This is the first study of its kind to examine the linkages between climate change, water resources and electricity production on a global scale,” said co-author and IIASA Energy Program Director Keywan Riahi (subscription). “We clearly show that power plants are not only causing climate change, but they might also be affected in major ways by climate.”

The study, which used computer modeling and data from more than 24,000 hydropower plants and nearly 1,500 thermoelectric plants, indicates that the areas most at risk of decreases in usable capacity for electricity production are the United States, southern and central Europe, Southeast Asia, southern parts of South America, Africa and Australia—regions where the study authors say big increases in water temperature will combine with projected decreases in mean annual streamflow.

The potential water supply shortfall coincides with a predicted doubling in demand for water for power generation over the next 40 years.

The study also explored adaptation measures, concluding that increases in power plant efficiency and switches in cooling sources would reduce most regions’ vulnerability to water constraints as would improved cross-sectoral water management during drought periods.

Data Points to Hotter Years

Late last year, the World Meteorological Organisation pegged 2011–15 as the hottest five-year period on record. But data from the Met Office suggests 2016 will be warm, too—warmer than the office’s forecast for 2015.

“This forecast suggests that by the end of 2016 we will have seen three record, or near-record years in a row for global temperatures,” said Adam Scaife, head of long-range prediction at the Met Office.

El Nino and climate change were among the reasons cited for the increase—an estimated 1.29 and 1.73 degrees Fahrenheit higher than the average global temperature in the second half of the 20th century. The Met Office, Express reports, does not expect the record-breaking run to continue indefinitely, but it shows how factors like an El Nino are working together to push temperatures to unprecedented levels of warmth.

Climate Central categorized the changes as a “global warming spurt,” that may be amplified by a slower-moving cycle of the Pacific Ocean—the Pacific Decadal Oscillation—that is also being amplified by climate change and that is the subject of some recent studies.

“Last time we went from a negative to a positive was the mid-70s,” said Gerald Meehl, a National Atmospheric Research scientist, speaking about a warming slowdown linked to Pacific Decadal Oscillation. “Then we had larger rates of global warming from the 70s to the 90s, compared to the previous 30 years. It’s not just an upward sloping line. Sometimes it’s steeper, sometimes it’s slower.”

Clean Power Plan Sees Challengers, Supporters

The deadline for filing legal challenges to the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan, which aims to limit carbon dioxide emissions from power plants, triggered a host of new lawsuits targeting the rule. To date, 27 states, along with trade groups and companies, are asking the U.S. Court of Appeals for the D.C. Circuit to delay implementation of the rule (subscription). Among the arguments—the EPA illegally issued duplicative rules for coal-fired plants and infringed on states’ rights (subscription).

Still, some states are beginning to wade through the rule. And many of the nation’s largest cities are seeking to back it. The National League of Cities, the U.S. Conference of Mayors and others are filing a motion to participate in litigation as amici curiae (friends of the court).

“The acute relevance of climate change to local governments’ responsibilities and activities has led members of the Local Government Coalition to grasp both the need to adapt to climate change and the costs of failing to act to mitigate it,” the filing said. “Prompted by lived experience and by the prospect of future impacts, they [the groups] have made efforts both to adapt to their changing climatic circumstances and to slow or eliminate their greenhouse gas emissions.”
