President Donald Trump signed a long anticipated executive order greatly diminishing the role climate change plays in U.S. government decision making by directing the U.S. Environmental Protection Agency (EPA) to review the Clean Power Plan, which sets limits on carbon dioxide emissions from existing fossil-fuel fired power plants.

The order directs each executive department and agency in the federal government to identify regulations, rules, policies, and guidance documents that slow or stop domestic energy production. In addition, the order also calls to review use the “social cost of carbon,” a metric for weighing the potential economic damage from climate change. Effective immediately, it instructs federal officials to use the 2003 Office of Management and Budget guidance “when monetizing the value of changes in greenhouse gas emissions resulting from regulations, including with respect to the consideration of domestic versus international impacts and the consideration of appropriate discount rates, agencies shall ensure, to the extent permitted by law.”

Regulations affecting methane leaks at oil and gas production facilities and hydraulic fracturing will all be reviewed, and a moratorium on coal leases on federal lands will be eliminated.

“My administration is putting an end to the war on coal,” said Trump. “I made them this promise. We will put our miners back to work.”

Coal’s share of the electric sector dwindled in the last decade to some 32 percent last year, according to The Associated Press, while gas and renewables have made gains as hundreds of coal-burning power plants have been retired or are on schedule to retire soon.

Low natural gas prices are, in large part, responsible for those retirements, making it unlikely that rolling back the Clean Power Plan will bring back coal jobs. Given the way market forces—rather than regulations—have hurt the coal industry and reduced employment Trump should “temper his expectations,” said Robert Murray, the founder and CEO of Murray Energy.

“[Utilities] are not going to flip a dime and say now it’s time to start building a whole bunch of coal plants because there’s a Trump administration,” said Brian Murray, director of the Environmental Economics Program at the Nicholas Institute for Environmental Policy Solutions.

Scientists Propose “Carbon Law”; Human Fingerprint Evident in Extreme Weather Events

An article published in Science says that “alarming inconsistencies” remain between the Paris Agreement’s science-based targets and national commitments. To harness the dynamics associated with disruption, innovation, and nonlinear change in human behavior and to calibrate for “political short-termism,” the authors propose that the decarbonization challenge be framed as a global decadal roadmap based on a “carbon law” of halving carbon dioxide emissions every decade.

Inspired by Moore’s Law, which predicted steady advances in computing power, the carbon law, say the researchers, is a flexible way to think about reducing carbon emissions because it can be applied across borders and economic sectors and at both regional and global scales.

It would require fossil-fuel emissions to peak by 2020 and to fall to zero by 2050 to meet the Paris Agreement’s goal of limiting global temperature rise to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. The idea is to reduce the risk of blowing the remaining global carbon budget to stay below 2 degrees Celsius by making the greatest efforts to reduce emissions now rather than later.

The researchers call for a ramping up of technologies to remove carbon from the atmosphere, a rapid reduction of emissions from agriculture and deforestation, and a doubling of renewables in the energy sector every five to seven years.

“We are already at the start of this trajectory,” said lead author Johan Rockstrom, director of the Stockholm Resilience Centre at Stockholm University. “In the last decade, the share of renewables in the energy sector has doubled every 5.5 years. If doubling continues at this pace, fossil fuels will exit the energy sector well before 2050.”

By 2020, according to the roadmap outlined by authors, the world would implement “no-brainer” policies, including ending fossil-fuel subsidies, putting a $50 per ton price on carbon emissions, and cracking down on energy efficiency. Both coal and polluting vehicles would have to be phased out, and new clean technology, including superconducting electricity grids, would have to be developed.

In the 2030s, coal use would end in the energy sector and in the 2040s oil use would end. By 2050, the carbon price would have risen to $400 per ton.

A study published Monday in the journal Scientific Reports suggests human-caused global warming is changing the behavior of planetary waves such as the jet stream in a way that intensifies droughts, wildfires and floods (subscription).

“We came as close as one can to demonstrating a direct link between climate change and a large family of extreme recent weather events,” said Michael Mann, a professor of atmospheric science at Pennsylvania State University and lead author of the study.

Authors used computer simulations, historical temperature data going back as far as 1880 and roughly 50 climate models to explore a series of unusual and deadly weather events, which they connect with an increase in the stalling of the jet stream, a phenomenon that occurs with a decreased temperature difference between the Arctic and tropical air streams. Conditions that favor that phenomenon have increased nearly 70 percent since the start of the industrial age—and most of that change has occurred in the past four decades, according to the study.

“The more frequent persistent and meandering jetstream states seems to be a relatively recent phenomenon, which makes it even more relevant,” said co-author Dim Coumou from the Department of Water and Climate Risk at VU University in Amsterdam. “Such non-linear responses of the Earth system to human-made warming should be avoided. We can limit the risks associated with increases in weather extremes if we limit greenhouse-gas emissions.”

Keystone Pipeline Application Approved

President Donald Trump continued to tout restoration of American jobs with his approval of a Canadian firm’s application to construct the Keystone XL pipeline, which would run from Canada to Nebraska, linking existing pipelines to carry oil to refineries in the Gulf of Mexico.

“It’s a great day for American jobs, a historic day for North America and energy independence,” said Trump Friday. “This announcement is part of a new era of American energy policy that will lower costs for American families, and very significantly reduce our dependence on foreign oil.”

The Obama administration had cited environmental concerns in rejecting the Keystone permit in 2015. In the 30-page explanation that the State Department gave for its presidential permit, signed by Under Secretary of State for Political Affairs Thomas A. Shannon Jr., it said it relied on yet earlier environmental studies into the pipeline’s possible environmental effects. The only new material in the permit is communications from TransCanada.

“In making his determination that issuance of this permit would serve the national interest, the Under Secretary considered a range of factors, including but not limited to foreign policy; energy security; environmental, cultural, and economic impacts; and compliance with applicable law and policy,” a statement on the U.S. Department of State website reads.

On Monday, President Donald Trump signed an order that will require federal agencies to cut two existing regulations for every new rule and that will set an annual cap on the cost of new regulations with the exceptions of military and national security regulations. For fiscal year 2017, the cap will require that the cost of new regulations be completely offset by the rescinding of existing rules. Starting in 2018, the order directs the White House Office of Management and Budget head to give each agency a budget for increasing or decreasing regulatory costs.

Yet, legal experts suggest that the executive order could be impossible to implement because many regulations are required by laws written by Congress.

“It should be noted that no [executive order] can change underlying statutes adopted in the regular order by Congress and signed by the president,” Scott Segal, an industry lawyer at Bracewell LLP, told ClimateWire (subscription).

The new order comes on the heels of a Congressional Research Service study finding that the Clean Air Act’s regulatory structure “faces an unusual degree of uncertainty” this year, with one or more branches of government poised to weigh in on key existing EPA rules. Those rules include the Clean Power Plan, methane rules for new or substantially modified oil and gas operations, and EPA’s latest ambient air quality standards for ozone. Yet other rules could be vulnerable under the Congressional Review Act, which allows Congress 60 legislative working days from the time a federal regulation is finalized to pass a “joint resolution of disapproval” on the rule.

The House passed two bills on Wednesday invoking the seldom used Congressional Review Act to attempt to roll back the Stream Protection Rule and the Securities and Exchange Commission rule requiring oil, gas and mining companies to reveal payments made to foreign governments. The rules were among five Obama administration regulations, including the Bureau of Land Management’s restrictions on methane emissions from flaring and venting during oil and gas operations on public and tribal lands, being targeted for reversal.

Trump has targeted specific regulations he believes hamper job growth, including the Waters of the U.S. Rule and the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan, which aims to limit carbon pollution from existing power plants but is under a Supreme Court stay.

Trump Nominates Supreme Court Justice; Some Cabinet Appointees Move Forward

President Donald Trump on Tuesday appointed 10th Circuit Judge Neil Gorsuch as his nominee to fill the Supreme Court seat left vacant last February by the death of Justice Antonin Scalia. The decision, which has implications for environmental policy, comes as Trump promised—within two weeks of taking office.

Gorsuch’s parallels to Scalia were described by SCOTUSBlog writer Eric Citron as “eerie.”

“He is an ardent textualist (like Scalia); he believes criminal laws should be clear and interpreted in favor of defendants even if that hurts government prosecutions (like Scalia); he is skeptical of efforts to purge religious expression from public spaces (like Scalia); he is highly dubious of legislative history (like Scalia); and he is less than enamored of the dormant commerce clause (like Scalia),” Citron wrote.

Although Gorsuch hasn’t ruled on many environmental matters, Inside EPA reports that he has called for limiting the discretion of the EPA and other agencies to interpret their own authority. Last year, in Gutierrez-Brizuelo v. Lynch, Gorsuch indicated he was fine without Chevron deference, the legal doctrine granting government agencies interpretation of ambiguous statutes unless their interpretation of a statute is unreasonable.

“We managed to live with the administrative state before Chevron. We could do it again,” wrote Gorsuch in the majority opinion.

In that opinion, Gorsuch argued that the meaning of the law is for judges, not federal bureaucrats, to decide.

“Where in all this does a court interpret the law and say what it is?” Gorsuch said. “When does a court independently decide what the statute means and whether it has or has not vested a legal right in a person? Where Chevron applies that job seems to have gone extinct.”

Also this week, several of Trump’s cabinet picks—Department of Energy Secretary nominee Rick Perry, U.S. Attorney General nominee Jeff Sessions and Department of the Interior nominee Ryan Zinke—gained committee approval and now move forward for consideration by the full Senate.

All 10 Democrats on the Senate Environment and Public Works Committee, which is tasked with considering whether to move Scott Pruitt’s nomination to lead the EPA to the full Senate, opted to boycott the Wednesday meeting. They said Pruitt failed to provide substantive answers to questions about rules governing air pollution, toxic chemicals and lead in gasoline. But today, Republicans on the committee advanced Pruitt’s nomination on a party line vote after suspending committee rules because of the boycott.

Rex Tillerson, the former chairman and chief executive of Exxon Mobil, was confirmed by the Senate as the next Secretary of State by a 56-43 vote and was sworn in Wednesday evening. At his confirmation hearing, he acknowledged that the climate is changing but said that he believes science is not conclusive on the issue of how rising greenhouse gas emissions will affect life on Earth. He expanded on his views when providing written responses to questions posed by two senators.

“I agree with the consensus view that combustion of fossil fuels is a leading cause for increased concentrations of greenhouse gases in the atmosphere,” he wrote to Senator Ben Cardin of Maryland. “I understand these gases to be a factor in rising temperature, but I do not believe the scientific consensus supports their characterization as the ‘key’ factor.”

Study Says Carbon Capture Necessary to Meet Paris Agreement Goal

The global climate can survive the possible withdrawal of the United States from the Paris Agreement, said the authors of a study published this week in the journal Nature Climate Change. The bigger threat, they said, is a world without widespread deployment of carbon capture and storage (CCS) technologies. Absent those technologies, achieving the climate treaty’s goal to limit warming to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius could be impossible.

The authors reached that conclusion by reviewing past energy trends and examining nearly 150 countries’ pledged carbon reduction targets in the context of more than 100 climate simulations indicating how changes in energy production and use through 2040 could meet the 2 degrees Celsuis goal. To deal with the mix of targets—among them, straight emissions reductions (for example, 30 percent by 2030), lowered emissions intensity (emissions per unit of GDP), and technology deployment (for example, expansion of renewables)—the study used the Kaya Identity method, which breaks the carbon dioxide emissions rate into the human factors that affect it—broad factors such as GDP and more specific ones such as quantity of deployed renewables.

The study paints a good news-bad news picture of progress toward the 2 degrees Celsius goal. It indicates that the rate of global emissions has leveled off over the last few years due to a reduction in coal burning by China, a shift from coal to gas and renewables plus increased industrial energy efficiency in the United States, rapid expansion of renewables in the European Union, and slowed GDP growth in the U.S., EU and China. But sustaining this trend of decreasing carbon intensity of energy will not be easy. Although renewables development is keeping pace with 2 degree Celsius scenarios, nuclear power is lagging and CCS is barely past the starting gate. Only a few CCS facilities are operational, and only a couple of dozen are in construction.

“The greatest challenge is the slower-than-expected rollout of technologies to capture and permanently store carbon from fossil fuel and bioenergy combustion,” said study co-author Robbie Andrew of the Centre for International Climate and Environmental Research (CICERO). “Most scenarios suggest the need for thousands of facilities with carbon capture and storage by 2030, and this compares with the tens currently proposed.”

Thus far, high up-front costs have stymied development of commercial-scale CCS plants. If they don’t materialize, the world faces a harsh reality, suggests lead author Glen Peters of CICERO.

“If we don’t have CCS, then we will need to reduce use of fossil fuels much faster and in a much more disruptive way,” he said.

Study co-author Robert Jackson of Stanford University noted that CCS technology will prove even more crucial if President Donald Trump makes good on his pledge to revive the nation’s limping coal industry.

“There’s no way to reduce the carbon emissions associated with coal without carbon capture and storage,” Jackson said.

We may find out soon whether Trump will follow through on his pledge to remove the U.S. from the Paris climate deal when he issues an expected review of the U.S.’s involvement in multinational treaties.  InsideEPA lays out mechanisms through which the administration could do so (subscription).

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, enters into force Friday. Just three days later, the Twenty-Second Conference of the Parties to the United Nations Framework Convention on Climate Change (COP22), kicks off in Marrakech, Morocco. But, discussion of fundamental issues of the Paris Agreement’s implementation such as transparency rules, climate finance or pre-2020 carbon cuts may be overshadowed—at least in the first few days—by the results of the Nov. 8 U.S. presidential election reports Climate Home.

When it comes to implementing the Paris Agreement, there’s a lot of negotiating left.

“Whilst Paris’ entry into force is great news it’s a bit of a shock for negotiators who weren’t expecting it for a few years yet,” said Camilla Born, a policy advisor at E3G. “Decisions on how the sequencing will work now that particular landmark has been brought forward will be made and negotiators will begin work on the rulebook in earnest. The rulebook will be crucial to ensure that countries are able to consistently track progress and create the best foundation for securing upward ambition moving forward.”

So what exactly is left to decide? For one, financing. There’s still uncertainty surrounding the pathway to mobilizing $100 billion in climate finance for developing countries by 2020, the rules for reporting finance, and how to scale up adaptation finance.

A new report published by the Harvard Belfer Center features a collection of expert briefs—two penned by colleagues at the Nicholas Institute for Environmental Policy Solutions—that addresses the opportunities for, and challenges to, elaborating, implementing, and complementing the Paris Agreement.

Study Highlights Significance of Limiting Warming for Mediterranean

According to a study published in the journal Science, southern Spain and other parts of the Mediterranean region could become a desert by 2100 absent efforts to sharply limit global average warming.

The authors reached that conclusion on the basis of historical vegetation data and computer models, which they used to forecast the likely impact of climate change on the region under four greenhouse gas emissions scenarios, including two scenarios reflecting the two ends of the Paris Agreement’s global warming limit range—1.5 degrees Celsius to 2 degrees Celsius above pre-industrial levels. They found that the region would avoid desertification only if global warming remains at or below 1.5 degrees Celsius this century. Average global temperatures have already risen by 1 degree Celsius since pre-industrial times.

“With 2 degrees of warming, for the Mediterranean we will have a change in the vegetation which has never been known in the past 10,000 years,” said lead author Joel Guiot of Aix-Marseille University.

“The main message is really to maintain at less than 1.5C,” he added. “For that, we need to decrease the emissions of greenhouse gases very quickly, and start the decreasing now, and not by 2020, and to arrive at zero emissions by 2050 and not by the end of the century.”

Sea Level Rise May be Underestimated

The longest and highest-quality records of historical ocean water levels may have underestimated the amount of global average sea level rise that occurred during the 20th century, according to a new study in the journal Geophysical Research Letters.

“It’s not that there’s something wrong with the instruments or the data,” said Phillip Thompson, associate director of the University of Hawaii Sea Level Center in the School of Ocean and Earth Science and Technology, Manoa, “but for a variety of reasons, sea level does not change at the same pace everywhere at the same time. As it turns out, our best historical sea level records tend to be located where 20th century sea level rise was most likely less than the true global average.”

The authors, from the National Aeronautics and Space Administration (NASA) and the University of Hawaii, suggest it is “highly unlikely” global average sea level rose less than 5.5 inches during the 20th century—most likely rise was closer to 6.7 inches.

European Union (EU) environment ministers on Friday approved ratification of the Paris Agreement. The approximately one-month EU ratification process means that the requirements for a 30-day countdown for the agreement to take effect will be met in November.

“Today is an important day not only for our action on climate but also for unity we have demonstrated,” said László Sólymos, EU Environment Council president and the Slovak minister for the environment. “This means that EU and its member states will add their weight to trigger the entry into force of the Paris Agreement.”

Thus far, 61 countries representing 47.79 percent of global greenhouse gas emissions have joined the Paris Agreement. Ratification of the agreement is complete when 55 countries accounting for 55 percent of global greenhouse gas (GHG) emissions sign on. The decision of the EU’s Environment Council to fast track ratification on behalf of the EU’s 28 member states, including the U.K., increases the share of ratifying nations’ emissions by 12 percent.

The Paris Agreement, signed by nearly 200 nations last December, aims to limit global warming to “well below” two degrees Celsius compared to pre-industrial times and to attempt to hold it to 1.5 degrees Celsius.

The move by the EU came a day after seven distinguished climate scientists led by Robert Watson, a former chairman of the United Nations’ Intergovernmental Panel on Climate Change, asserted in a report that the opportunity to meet the 1.5 Celsius goal “has almost certainly already been missed” and that even the 2 Celsius pathway would be irrevocably lost absent increased emissions cuts under the Paris Agreement.

“If governments are serious about trying to achieve even the 2 degree goal, they will have to double and re-double their efforts—now,” Watson said. “I think it is fair to say that there is literally no chance of making the 1.5 C target.”

According to Watson and the other report authors, the world could experience 2 Celsius of warming—the point at which many scientists believe climate change will become dangerous—as early as 2050.

Poll: Deep Distrust of Climate Scientists, Political Divide on Climate Change

Climate scientists have a problem. A new Pew Research poll finds that most Americans doubt their consensus on global warming and don’t have “a lot” of trust in them to provide accurate information about the issue. According to the in-depth survey on “the politics of climate” released Tuesday, only 27 percent of Americans agree that “almost all” climate scientists say that human behavior is mostly responsible for climate change—a figure Pew contrasted with a 2013 United Nations Intergovernmental Panel on Climate Change report stating with 95 percent certainty that human activity is the main cause of observed warming since the mid-20th century. Only one-third of those surveyed said that climate scientists understand “very well” whether global climate change is occurring.

Like other Pew surveys conducted from 2006 to 2015, the new survey finds that one of the strongest predictors of views on the causes, cures, and urgency of climate change is party identification: among the one third of Americans who say they care a great deal about climate change, 72 percent are Democrats and 24 percent are Republicans. Approximately three quarters of Democrats believe climate change is mainly a result of human activity; fewer than a quarter of Republicans concur.

“People on the ideological ends of either party—that is, liberal Democrats and conservative Republicans—see the world through vastly different lenses across all of these judgments,” the report found.

The Pew survey also found no strong correlation between scientific knowledge and views on climate issues.

“To the extent that science knowledge influences people’s judgments related to climate change and trust in climate scientists, it does so among Democrats, but not Republicans,” wrote Pew researchers. “For example, Democrats with high science knowledge are especially likely to believe the Earth is warming due to human activity, to see scientists as having a firm understanding of climate change, and to trust climate scientists’ information about the causes of climate change. But Republicans with higher science knowledge are no more or less likely to hold these beliefs. Thus, people’s political orientations also tend to influence how knowledge about science affects their judgments and beliefs about climate matters and their trust in climate scientists.”

The political divide on solutions to climate change is as great as it is on causes: More than three quarters of liberal Democrats but less than a quarter of conservative Republicans said restricting emissions from power plants could make a big difference. A similar divide was evident in views on the usefulness of an international agreement to limit carbon emissions.

The survey did identify one area of agreement: more than 80 percent of Americans all across the political spectrum support greater use of wind and solar power, a view attributable to financial, health-related and environmental motivations.

EPA Data Says Power Plant Emissions Down

Greenhouse gas emissions from United States power plants dropped a little more than 6 percent last year compared to 2014 levels, according to data provided by 8,000 facilities and suppliers to the U.S. Environmental Protection Agency’s Greenhouse Gas Reporting Program. These reporters account for about half of all U.S. greenhouse gas emissions.

Released annually, the data details emissions by industrial sector, geographic region and individual facilities. It found that in 2015, reported emissions from large industrial sources were 4.9 percent lower than 2014, and 8.2 percent lower than 2011. Petroleum and natural gas facilities were the second largest stationary source of emissions, reporting 231 million metric tons of greenhouse gas emissions—1.6 percent lower in 2015 than in 2014, but 4.1 percent higher than in 2011.

A study published last week in Nature Geoscience provides the first measurements of greenhouse gases from permafrost under Arctic lakes in Alaska, Siberia, and Canada. Although the research reveals that only a small amount of old carbon has been released in the past 60 years, it also suggests that much more could be released as the Arctic warms up faster than any other place on Earth.

“It’s a lit fuse, but the length of that fuse is very long,” said lead author Katey Walter Anthony of the University of Alaska. “According to the model projections, we’re getting ready for the part where it starts to explode. But it hasn’t happened yet.”

The scientists determined that the permafrost-carbon feedback is thus far small by looking at aerial photographs and using radiocarbon dating to determine the age of methane emitted from the Arctic lakes that are expanding to consume and thaw terrestrial permafrost. As that permafrost melts and decomposes, it releases ancient carbon as carbon dioxide and methane. Analysis of 113 radiocarbon dating measurements and 289 soil organic carbon measurements showed that approximately 0.2 to 2.5 petagrams of permafrost carbon was released as methane and carbon dioxide in the past six decades.

The billions of tons of carbon stored in permafrost are approximately double the amount currently in the atmosphere. Many researchers are concerned that emission of that stored carbon will contribute to warming that then contributes to permafrost thawing in an accelerating feedback loop.

NASA: Temperature Reconstructions Suggest Achievement of Paris Agreement Goals “Unlikely”

The Paris Agreement’s goal to limit Earth’s temperature increase to “well below” 2 degrees Celsius and to pursue efforts to limit that increase to 1.5 degrees Celsius above pre-industrial levels is unlikely to be achieved according to temperature reconstructions from the National Oceanic and Atmospheric Administration and the National Aeronautical and Space Administration (NASA). Those reconstructions reveal that the world is heating up faster than at any other time within the past 1,000 years. Over the next 100 years, according to NASA, it will continue to warm at least 20 times faster than the historical average.

“In the last 30 years we’ve really moved into exceptional territory,” said Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies. “It’s unprecedented in 1,000 years. There’s no period that has the trend seen in the 20th century in terms of the inclination (of temperatures). Maintaining temperatures below the 1.5C guardrail requires significant and very rapid cuts in carbon dioxide emissions or coordinated geo-engineering. That is very unlikely. We are not even yet making emissions cuts commensurate with keeping warming below 2C.”

Using evidence left in tree rings, layers of ice in glaciers, ocean sediments, coral reefs, and layers of sedimentary rocks, NASA figures that the past century’s warming of 0.7 degrees Celsius is roughly 10 times faster than the average rate of ice-age-recovery warming.

This year, the average global temperature reached 1.38 Celsius above levels observed in the 19th century, just 0.12 Celsius below the 1.5 Celsius limit that nations aimed for in the Paris Agreement.

Climate Change Major Focus at G20 Summit

Climate change is among the topics world leaders are expected to discuss at a G20 summit in China, beginning September 4.

“This is the first time that the G20 leaders are gathering to discuss the Sustainable Development Goals and climate change, (and) how we implement them in parallel,” said United Nations Secretary-General Ban Ki Moon.

President Obama, who began his 10-day trip to Asia on Wednesday, is expected to stress the urgency of climate change. And some media outlets are reporting that the United States and China are expected to announce their ratification of the Paris Agreement prior to the start of the G20 Summit, but the White House has made no formal statement to this effect.

“We’ve made the commitment that we will join in 2016. And we’ve made the commitment to do that as soon as possible this year,” said Brian Deese, senior advisor to the president. “With respect to exactly when, I don’t have any announcements on that front. But we’ve committed, and we’ve been working on that issue.”

Nations to Sign Paris Climate Agreement Friday

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.
