Atmospheric Carbon Dioxide Concentration Sets New Record

The Nicholas Institute for Environmental Policy Solutions at Duke University

For the first time in recorded history, Earth has sustained an atmospheric concentration of carbon dioxide in excess of 410 parts per million—a symbolic red line in the methodical upward march of greenhouse gas concentrations. The April Keeling Curve measurements at the Mauna Loa Observatory are 30 percent higher than the first Keeling Curve measurements, 315 parts per million, at the observatory in 1958, and 46 percent higher than concentrations recorded during the Industrial Revolution in 1880. They are the highest in the 800,000 years for which scientists have good data, thanks to paleoclimate records like tree rings and ice cores.

Ralph Keeling, director of the CO2 Program at the Scripps Institution of Oceanography, which monitors the readings and calculates the one-month averages, said the rate of carbon dioxide concentration in the atmosphere has been increasing faster in the last decade than in the 2000s.

“It’s another milestone in the upward increase in CO2 over time,” said Keeling, who is also the son of Charles David Keeling, creator of the Keeling Curve. “It’s up closer to some targets we don’t really want to get to, like getting over 450 or 500 ppm. That’s pretty much dangerous territory.”

Last year the National Oceanic and Atmospheric Administration’s climate department reported that atmospheric carbon dioxide levels in 2016 were at levels not seen on Earth for millions of years, when temperatures were 3.6 to 5.4 degrees Fahrenheit warmer, and sea level was 50 to 80 feet higher than today.

Powelson Reflects on PJM Fuel Security Announcement, Defense Production Act

What are the primary drivers of change in the PJM Interconnection, which operates the electric grid for a 13-state region? Technology and people. That was the message from air and energy regulators from states in the PJM electricity market at an event co-sponsored by the Great Plains Institute and Duke University’s Nicholas Institute for Environmental Policy Solutions.

The event, keynoted by Robert Powelson of the Federal Energy Regulatory Commission (FERC), focused on change and the tensions revealed as different actors drive these changes or respond to their effects. Powelson reflected on PJM’s late April announcement that it will conduct a study to understand “fuel-supply risks in an environment trending towards greater reliance on natural gas.” PJM said it will conduct a three-phase analysis over several months to determine whether it can withstand a cyberattack on a natural gas delivery system or a prolonged cold snap.

Powelson cautioned that people should not read into PJM’s announcement that PJM may pay coal and nuclear generators to be backstops in the event of fuel delivery interruptions. “I think what PJM is saying is ‘we’re going to look at it and we’re going to do it in a market-based approach.’ There might be other technologies out there that have the same [fuel security] characteristics. It could be an oxidized fuel cell. It could be storage. It’s going to be a level playing field discussion. … It’s going to be done in a fuel-neutral, technology-neutral way.”

He called PJM’s capacity market proposal before FERC “a jump ball” aimed at neutralizing the effects of some state subsidies intended to prop up nuclear. PJM wants FERC to direct operators to update market compensation for power plants to reflect resilience attributes.

Powelson also touched on the U.S. Department of Energy plan to look into whether it can keep some struggling coal and nuclear plants operating by invoking the Defense Production Act—a 1950 law giving the president a broad range of power to require businesses to prioritize contracts for materials deemed vital to national security.

Invoking the act, Powelson said, “would lead to the unwinding of competitive markets in this country.”

Climate Talks Stall, U.N. Schedules Extra Sessions

As the latest round of Paris Agreement talks wind down May 10, delegates are marking their calendars for extra sessions to accomplish what they could not in Bonn, Germany, over the last two weeks: finalize the text of a rulebook for the agreement that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. On Monday, Executive Secretary of U.N. Climate Change Patricia Espinosa said producing a rulebook was impossible at the current conference.

“A single negotiating text. No,” said Espinosa. “That would really not be possible. It will all come together when it comes to the level of the COP [Conference of the Parties], of the conference in December.”

Given insufficient progress in Bonn, U.N. officials announced on Tuesday that they were adding a week-long session in Bangkok in September in order to meet the deadline for a rulebook at the main summit in Katowice, Poland, in December. Without that document, negotiators would have no basis for those talks.

Several issues stalled the Bonn negotiations. Most developed countries want to know how much climate funding they are committing to developing countries, which contributed the least to climate change but suffer its worst effects. They also want to understand how that funding will be adjusted to support countries’ progressive emissions reductions every five years. There is also pushback from developed countries on funding for climate impacts to which developing countries can no longer adapt.

At the Talanoa Dialogue, an international storytelling side event aimed at increasing global ambition to reduce climate change, State Department climate negotiator Kim Carnahan described President Donald Trump’s vision of a “balanced” global energy landscape and said the administration’s “position on the Paris Agreement remains unchanged,” a reference to Trump’s decision to withdraw the United States from the Paris Agreement. She maintained that the United States would ensure the viability of its nuclear power sector, currently its largest single source of no-carbon energy. Carnahan also noted the power sector carbon reductions that have accompanied increased natural gas production from hydraulic fracturing.

Report Says Global Carbon Dioxide Emissions on the Rise

The Nicholas Institute for Environmental Policy Solutions at Duke University

The International Energy Agency’s (IEA) first Global Energy and CO2 Status Report, released last week, had two major findings: preliminary estimates for 2017 suggest that global energy demand rose 2.1 percent—more than twice the previous year’s rate—and carbon dioxide emissions rose 1.4 percent, the first time they’ve increased in three years. Although emissions increased in most countries, they decreased in the United States and several other countries largely due to renewable energy deployments.

“The significant growth in global energy-related in 2017 tells us that current efforts to combat climate change are far from sufficient,” said IEA Executive Director Fatih Birol, who identified “a dramatic slowdown in the rate of improvement in global energy efficiency” as one of the causes.
That improvement in energy efficiency slowed from a rate of 2.3 percent a year over the last three years to 1.7 percent last year. Meanwhile, some 70 percent of 2017’s increased energy demand was met by fossil fuels. Emissions decreases in the United States, the U.K., Japan, and Mexico were insufficient to cancel out the increases in China and India.

According to the report, global energy-related carbon dioxide emissions reached a historical high of 32.5 gigatons in 2017, and current efforts to curb them are insufficient to meet Paris Agreement targets to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it to 1.5 degrees Celsius.

“Global emissions need to peak soon and decline steeply to 2020; this decline will now need to be even greater given the increase in emissions in 2017,” the report says.

Some of the report’s other findings:

  • Oil demand grew by 1.6 percent, more than twice the average annual rate over the past decade, driven by the transport sector and rising petrochemical demand.
  • Natural gas consumption grew 3 percent, the most of all fossil fuels, driven by China and the building and industry sectors.
  • Coal demand rose 1 percent, reversing declines over the previous two years, driven by an increase in coal-fired electricity generation, mostly in Asia.
  • Renewables had the highest growth rate of any fuel, meeting a quarter of world energy demand growth.
  • Electricity generation increased by 3.1 percent, much faster than overall energy demand, with India and China accounting for most of the growth.
  • Fossil fuels accounted for 81 percent of total energy demand, continuing a three-decades-long trend.

Decision on Tailpipe Emissions Standards Expected

The U.S. Environmental Protection Agency (EPA) is up against an April 1 deadline to determine whether to loosen vehicle tailpipe emissions standards for the years 2022 to 2025, leave them unchanged, or increase them. Reports in the Wall Street Journal and other media outlets suggest the decision is likely to indicate that future vehicle emissions standards should be eased.

The rules, negotiated with the vehicle industry in 2011, presently require automakers to nearly double the average fuel economy of new cars and trucks to 54.5 miles per gallon by 2025.

“The draft determination has been sent to OMB [Office of Management and Budget] and is undergoing interagency review,” said Liz Bowman, an EPA spokeswoman. “A final determination will be signed by April 1, 2018, consistent with the original timeline.”

Unclear is how a decision to ease standards might affect California, which can set its own fuel standards and is authorized to do so under the Clean Air Act. The state has suggested it may withdraw from the nationwide program if the EPA eases regulations.

“California is not the arbiter of these issues,” said Scott Pruitt, EPA administrator, in an interview with Bloomberg. The state “shouldn’t and can’t dictate to the rest of the country what these levels are going to be.”

“We have not seen the document in question, and California had no input into its content,” said California Air Resources Board spokesman Stanley Young. “We feel strongly that weakening the program will waste fuel, increase emissions and cost consumers more money. It’s not in the interest of the public or the industry.”

EPA Holds Final Clean Power Plan Hearing

The U.S. Environmental Protection Agency (EPA) wrapped up public hearings concerning its repeal of the Clean Power Plan—an Obama-era regulation that sets state-by-state carbon emissions reduction targets for power plants—in Wyoming on Tuesday. All public comments on the proposed repeal of the Clean Power Plan are due April 26.

Dialogue in Tuesday’s hearing followed the trend of the EPA’s three other public hearings, with some arguing that the Clean Power Plan is needed to combat climate change and others questioning its effectiveness in achieving climate goals. One point of contention is how the costs and benefits of the rule were calculated. Opponents say the benefits were inflated and the costs were minimized. Supporters say the rule actually undercounts the additional benefits of reducing hazardous air pollutants.

The EPA was expected do away with the signature climate regulation, which the Supreme Court stayed in early 2016 and which would require the U.S. electricity sector to cut its carbon dioxide emissions by up to 32 percent from 2005 levels by 2030. But the Trump administration might consider a replacement at the urging of power companies fearful that a repeal could trigger courtroom challenges that would lead to years of regulatory uncertainty.

Any replacement rule may be affected by the EPA’s plans to propose measures to limit which studies the EPA can use in pollution rules—measures that could potentially reduce calculation of the health benefits that come along with controlling carbon dioxide emissions.

Studies Assess Emissions; See Rise as Countries Meet to Negotiate Paris Agreement Terms

The Nicholas Institute for Environmental Policy Solutions at Duke University

Editor’s Note: The Climate Post will not circulate next Thursday due to the Thanksgiving holiday. It will return November 30.

Although the world’s greenhouse gas emissions leveled out between 2014 and 2016, new studies presented this week at the United Nations climate talks in Bonn, Germany, suggest that emissions will rise 2 percent in 2017.

“The temporary hiatus appears to have ended in 2017,” wrote Stanford University’s Rob Jackson, who along with colleagues at the Global Carbon Project tracked 2017 emissions to date and projected them forward in the journal Environmental Research Letters.

“Economic projections suggest further emissions growth in 2018 is likely,” wrote the authors.

The primary driver of the rising emissions increase is a 3.5 percent increase in China’s emissions due to decreased use of hydropower and an uptick in coal use. India is expected to see a 2 percent rise in emissions. Meanwhile, the United States, the world’s second largest emitter behind China, is projected to experience a 0.4 percent decline in emissions.

The studies add urgency to the efforts of those in Bonn to negotiate the terms of the 2015 Paris Agreement, the global treaty that aims to limit global warming. Corinne Le Quéré, lead author of the Global Carbon Budget 2017 study and director of the University of East Anglia’s Tyndall Centre for Climate Research, said the timeframe for meeting Paris Agreement targets is shortening: “Our expectations had always been that emissions would grow, but perhaps not as steeply as this.

“With global CO2 emissions from human activities estimated at 41 billion tonnes for 2017, time is running out on our ability to keep warming well below 2 degrees C, let alone 1.5C,” Le Quéré added.

COP 23: Coal, Finances, and Subnational Support

As signatories to the United Nations’ Framework Convention on Climate Change (COP 23) finish the second week of international climate talks in Bonn, Germany, their focus remains on hammering out the details of the Paris Agreement, the global treaty aiming to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius.

How exactly the needed actions will be financed is yet to be seen.

“We need all financial players—public, private, domestic, international—and including markets and regulators, to work together effectively to mobilize at least $1.5 trillion in climate finance that is needed every year,” said Eric Usher, head of Finance Initiative at the U.N. Environment Programme.

Now that the United States is the only country not supporting the Paris Agreement—President Donald Trump announced in June that it would withdraw from the agreement—the administration’s only appearance at the conference focused on fossil fuels.

George D. Banks, special adviser to President Trump on international energy issues, led a panel with top American energy executives, offering that “without question, fossil fuels will continue to be used, and we would argue that it’s in the global interest to make sure when fossil fuels are used that they be as clean and efficient as possible. This panel is controversial only if we choose to bury our heads in the sand.”

Despite the Trump administration’s stance on the agreement, U.S. states and cities are looking to take action on climate change. This week, 20 states and 50 cities signed a pledge to abide by the emissions reduction targets of the Paris agreement.

“It is important for the world to know, the American government may have pulled out of the Paris agreement, but the American people are committed to its goals, and there is nothing Washington can do to stop us,” former New York City mayor Michael Bloomberg said in Bonn.

The group is vowing to take measures, such as reducing coal-fired power and investing in renewable energy and efficiency, which would substantially reduce its carbon output.

Study: A Warming Planet Makes Harvey-like Storms More Likely

In the wake of Hurricane Harvey, some researchers pointed to the increased likelihood of extreme rain events as the planet warms, but a new study in the journal Proceedings of the National Academy of Sciences goes further. It supports the idea that the specific risk of such events is already on the upswing because of humans’ contributions to climate change. According to the study author, Massachusetts Institute of Technology hurricane expert Kerry Emanuel, since the end of the 20th century, global warming has helped increase the annual likelihood of Harvey-like rainfall in Texas by 6 percent. By century end, that probability could rise to 18 percent.

To better understand how climate change is skewing those odds, Emanuel generated 3,700 computerized storms for each of the three climate models used in the study. He situated Texas storms in the climates of the years from 1980 to 2016. In these climates, he found that an event producing 20 inches of rain was extremely rare. When he performed a similar analysis in the projected climates of the years 2080 to 2100, Harvey’s 33 inches of rain in Houston became a once-in-a-100-year event, rather than a once-in-a-2,000-year event, and for Texas as a whole, the odds increased from once in 100 years to once every 5.5 years.

“The changes in probabilities are because of global warming,” Emanuel said.

In the study, global warming helped slow hurricanes by pushing land and ocean temperatures closer together, leading to the kind of longevity witnessed with Harvey, but the other and greater effect of that warming is the atmosphere’s capacity to hold moisture.

“If [general circulation] slows down, then places near the coast will get more rain,” Emanuel said. “But the main reason our technique shows increasing rainfall is that there’s more water in the air.”

The significance of this study, Emmanuel noted, is to alert city planners to the changing probabilities of large-scale hurricanes in Texas.

“It is important for those people who will rebuild Houston and rethink its infrastructure to understand the magnitude of the risk and how it will change over time,” he said.

Paris Agreement, Subnational Actions a Focus at COP 23 Meeting

The Nicholas Institute for Environmental Policy Solutions at Duke University

This week, signatories to the United Nations’ Framework Convention on Climate Change (COP 23) meet in Bonn, Germany, to discuss implementation of the Paris Agreement, a global treaty that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. Before the meeting wraps up Nov. 17, signatories hope to lay the groundwork for the conclusion of the Paris agreement terms at COP24 in Poland, including rules on transparency, accounting, markets, and resilience.

“The conference in Bonn is a preparatory meeting for the next COP in Poland, where the fine print of the Paris Agreement will be decided,” said Jochen Flasbarth, state secretary in the German environment ministry. “In a nutshell, it’s about shaping the transparency rules on how states measure and report their progress in climate mitigation. The Paris Agreement is built as a bottom-up structure, where the [parties] themselves decide the contributions they can and want to make. This is why it’s most important to make sure that every party abides by their own targets and honestly reports about their efforts and results. So even though it’s very hard to communicate this to the public, the negotiations in Bonn are actually about the heart of the Paris Agreement.”

Since COP23 kicked off Nov. 6, two holdouts from the 2015 Paris Agreement signing—Syria and Nicaragua—have become signatories. That leaves the United States as the only country in the world not supporting the deal to limit global greenhouse gas emissions. President Donald Trump announced in June that the U.S. would withdraw from the climate agreement, a process that will be complete in 2020.

A significant focus at the COP23 is actions of cities, states, and other subnational actors that are stepping up to address climate change. Later this week, California Gov. Jerry Brown, together with former New York City mayor Michael Bloomberg, will release a new report highlighting the progress of U.S. states, cities, and businesses in addressing climate change.

U.S. states, such as California, are signaling even further climate action. Brown proposed linking his state’s carbon market with the European Union’s and announced plans to cooperate on market design and implementation in Brussels, Tuesday.

“I would hope that we could explore linking California and the European Union,” Brown said. “We are already linked with Quebec. We are about to be joined by Ontario. Other states are also considering joining. That would be a concrete investment kind of move that California and other states and provinces could become a part of.”

Study Finds Strong Link Between Climate Change and Human Activities

A scientific report, released last week, says that it is “extremely likely” the use of fossil fuels and human activities are the main cause of the global temperature rise that has created the warmest period in the history of civilization. According to that report, a global average temperature increase of 1.8 degrees Fahrenheit in the last 115 years has led to record-breaking weather events and temperature extremes.

“It is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century,” says the Climate Science Special Report, part of the Fourth National Climate Assessment. “For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.”

The assessment, mandated every-four-years by the Global Change Research Act, analyzes human and naturally caused global changes and their effects on everything from agriculture and energy production to human health. Produced by 13 federal agencies and peer-reviewed by the National Academy of Sciences, it is the United States’ most definitive statement on climate change science.

The Climate Science Special Report affirms that the United States is already experiencing more extreme heat and rainfall events and larger wildfires in the West, but sea-level rise may be the clearest evidence of climate change. More than 25 coastal U.S. cities are experiencing increased flooding, and seas could rise by from 1 to 4 feet by the year 2100. A rise of more than eight feet is “physically possible” with high emissions of greenhouse gases. Of the rapidly escalating levels of those gases in the atmosphere, the report states, “there is no climate analog for this century at any time in at least the last 50 million years.”

The report cautions that current climate models are likelier to underestimate future warming than to overestimate it. Although those models have accurately predicted the past few decades of warming, they may fail to capture how warm Earth can get. Researchers may not fully understand climate tipping points—difficult-to-predict points of no return.

Trump USDA Nominee Withdraws from Consideration

Sam Clovis, President Donald Trump’s pick for chief scientist of the Department of Agriculture, withdrew himself from consideration for the post. Clovis, whose nomination hearing was scheduled for this month, blamed the political tone in Washington for his decision in a letter to Trump.

“The political climate inside Washington has made it impossible for me to receive balanced and fair consideration for this position,” Clovis wrote.

The professor and conservative radio talk show host from Iowa, who served as national co-chair of Trump’s campaign, had come under fire after foreign policy adviser George Papadopoulos pled guilty to charges related to brokering of a relationship between the Trump campaign and Russian officials. Clovis was also scrutinized for his climate change skepticism and lack of an advanced science degree, a 2008 farm bill requirement of appointees to the position.

Ahead of Bonn Talks, Study Says Paris Agreement May Fall Short

The Nicholas Institute for Environmental Policy Solutions at Duke University

As the United Nations prepares to welcome delegates from across the world to Bonn, Germany, on Monday for the annual Conference of Parties meeting (COP23), the U.N. Environment Program (UNEP) has released its yearly “Emissions Gap” report indicating a disparity between the world’s stated ambitions on climate in the Paris Agreement and what actions are actually needed.

The report indicates the present national pledges under the agreement are only one third of the reduction in emissions required by 2030 to meet targets, which aim to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. The pledges by countries, it says, would lead to temperature rises of as much as 3 degrees Celsius or more by the end of this century, but it would make the chance of getting to 4 degrees Celsius or more of warming considerably smaller.

Although the gap between commitments could be large, the report suggests that it is still possible to close it in a cost-effective way. A large portion of reductions come from six specific efforts: solar energy; wind energy; efficient appliances; efficient passenger cars; aforestation; and stopping deforestation.

“These six categories sum up a potential of 18.5 GtCO2e in 2030 (range: 15-22 GtCO2e), making up more than half of the basic potential,” the report says. “Equally important, all these measures can be realised at modest cost, and are predominantly achievable through proven policies.”

What about the U.S.—the second largest emitter—not honoring its Paris Agreement commitment? Even though President Donald Trump withdrew the U.S. from the Paris Agreement this summer, the chances are good we can live up to the emissions reductions promised suggests UNEP Director Erik Solheim. “In all likelihood, the United States of America will live up to its Paris commitment, not because of the White House, but because of the private sector,” said  Solheim. “All the big American companies are dedicated to go in the green direction.”

Carbon Dioxide Levels Reach New High in 2016

The carbon dioxide (CO2) concentration in the atmosphere rose higher than it’s been in 800,000 years—145 percent of pre-industrial levels, according to a new report. The U.N. World Meteorological Organization (WMO) said in the annual Greenhouse Gas Bulletin that a strong El Niño event and human activity contributed to the increase of CO2 concentrations—403.3 parts per million last year, up from 400 in 2015.

“Without rapid cuts in COand other greenhouse gas emissions, we will be heading for dangerous temperature increases by the end of this century, well above the target set by the Paris climate change agreement,” said WMO Secretary-General Petteri Taalas. “Future generations will inherit a much more inhospitable planet. COremains in the atmosphere for hundreds of years and in the oceans for even longer. The laws of physics mean that we face a much hotter, more extreme climate in the future.”

The study uses monitoring by ships, aircraft and weather stations on land to track emissions trends since 1750. The carbon dioxide in the atmosphere, it said, is now increasing 100 times faster than at the end of the last ice age due to population growth, intensive agriculture, deforestation and industrialization.

Measures to mitigate climate change must be taken, the report warns, including work to develop renewable energy and transportation systems.

Studies Assess Cost and Effects of Climate Change

A report by the Government Accountability Office, Congress’s auditing arm, urges the Trump administration to take climate change risks seriously and begin formulating a response. The office analyzed the financial costs of extreme weather events and wildfires in the United States, finding that these events have cost the government more than $350 billion over the past 10 years.

“The federal government has not undertaken strategic government-wide planning to manage climate risks by using information on the potential economic effects of climate change to identify significant risks and craft appropriate federal responses,” indicates the study, which drew on interviews with 26 scientific and economic experts and 30 studies over two years to draw its conclusion. “By using such information, the federal government could take the initial step in establishing government-wide priorities to manage such risks.”

A separate study by a leading medical journal, The Lancet, focused on the impacts and cost of weather-related disasters and a warming climate.

“Between 2000-2016, there has been a 46 percent increase in the number of weather-related disasters, and 125 million adults aged over 65 were exposed to heat waves,” the journal indicated. “Increasing temperatures have led to around 5.3 percent loss in labor productivity, and economic losses linked to climate-related extreme weather events were estimated at $129 billion in 2016.”

The Lancet study cites a number of ways climate change is already affecting health—heat waves, mass migrations, infectious diseases, economic problems, natural disasters and malnutrition.

Senate Approves Funding for U.N. Climate Agency; House Votes on Funding for Methane Rule

The Nicholas Institute for Environmental Policy Solutions at Duke University

The Senate Appropriations Committee voted 16 to 14 to approve an amendment to restore funding for the United Nation’s Framework Convention on Climate Change (UNFCCC) in a spending bill for the State Department, setting up a negotiation with the House over its version of the State funding bill, which does not fund the U.N. climate agency.

“[This] fits in with Secretary of State [Rex] Tillerson’s desire that we both continue to monitor the changes in the world’s climate and that we keep a seat at the table,” said Sen. Jeff Merkley, D-Ore., who sponsored the amendment.

The Senate bill would direct $10 million to the body that oversees U.N. efforts to address climate change, despite President Donald Trump’s proposal to cut funding in his first budget draft earlier this year. Since 1992 the United States has contributed some 20 percent of operational funding—$6.44 million—for the secretariat of the UNFCCC and last year provided 45 percent—$2 million—to its science wing, the Intergovernmental Panel on Climate Change.

The Senate bill would not restore U.S. funding for the Green Climate Fund, which helps poor countries adapt to climate change.

The vote on the bill came between two highly destructive hurricanes that representatives of some small island nations are pointing to as they press their case for wealthy countries to pay not just for adaptation but also for climate-related “loss and damage.”

“If ever there was a case for loss and damage, this is it,” Ronny Jumeau, U.N. ambassador from Indian Ocean island nation the Seychelles, told Reuters, referring to Hurricane Irma and other recent storms.

“Hurricane Irma graphically shows the destructive power of climate change and underscores that loss and damage isn’t some abstract concept, but the reality of life today for the people who contributed least to the problem,” said Thoriq Ibrahim, Maldives’ environment minister who chairs the U.N. negotiating bloc Alliance of Small Island States.

On Wednesday, the House voted to block funding for an Obama-era U.S. Environmental Protection Agency (EPA) effort to limit methane emissions from new oil and gas drilling sites. EPA Administrator Scott Pruitt had imposed a two-year delay on the implementation of the 2016 regulation to review the rules and potentially roll them back. But in July, a federal appeals court blocked the Trump administration from eliminating the methane rule.

DOE Solar Program Hits Target Early; Funding Issued for Cybersecurity

The U.S. Department of Energy (DOE), this week, announced that efforts to make solar power more cost-competitive hit a key target. The average price of utility-scale solar is now 6 cents per kilowatt-hour (kWh)—a price hit three years ahead of a target DOE set through the SunShot Initiative in 2011.

“It’s important to celebrate the progress we’ve made, and be realistic about the challenges that lie ahead,” said Dan Simmons, acting assistant secretary for energy efficiency and renewable energy. “Solar’s costs have dramatically declined, but electricity rates have not. As we experience greater penetration of solar [photovoltaics], we experience new challenges.”

DOE attributed the early milestone to rapid declines in the cost of hardware.

In the same announcement, DOE said it will spend $82 million to research energy storage and technologies that could help grid operators detect problems rapidly not only to reduce physical and cyber vulnerabilities, but also to enable consumers to manage electricity use.

Separately, the DOE also announced plans to fund $20 million in energy cybersecurity projects through an array of national labs, universities and private companies.

“This investment will keep us moving forward to create yet more real-world capabilities that the energy sector can put into practice to continue improving the resilience and security of the country’s critical energy infrastructure,” said Energy Secretary Rick Perry.

Hurricanes Raise Climate Change Issue

The devastation following two hurricanes—Harvey and Irma—that made landfall in the United States this month and last have renewed debate about climate change. On a plane ride from Columbia, Pope Francis—who has spoken out about the issue previously—weighed in on the debate.

“If we don’t turn back, we will go down,” said Pope Francis. “Those who deny it should go to the scientists and ask them. They are very clear, very precise. They [world leaders] decide and history will judge those decisions.”

Although many in the Trump administration are not discussing climate change, it is rumored that National Economic Council Director Gary Cohn will host an energy and climate discussion with international officials.

The invitation, obtained by Politico, says the gathering is an “opportunity for key ministers with responsibility for these issues to engage in an informal exchange of views and discuss how we can move forward most productively.”

A White House official told The New York Times that the meeting was intended to be an informal discussion to help the Trump administration find a way to fulfill the president’s pledge to reduce emissions without harming the American economy.

EPA Administrator Says United States Should Exit Paris Agreement

The Nicholas Institute for Environmental Policy Solutions at Duke University

In an interview last week, U.S. Environmental Protection Agency Administrator (EPA) Scott Pruitt said that the United States should “exit” the Paris Agreement—the first time such a high-ranking Trump administration official has so explicitly rejected the global accord to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. Pruitt also vowed that the EPA would “roll back” the Clean Power Plan, a key component of former Obama administration’s plan to meet the U.S. pledge under the Paris Agreement, which calls for an emissions reduction of 26–28 percent from 2005 levels by 2025.

“Paris is something we need to look at closely,” Pruitt said. “It’s something we need to exit in my opinion. It’s a bad deal for America It’s an ‘America second, third or fourth’ kind of approach.”

Pruitt said that he would not risk U.S. jobs to comply with the agreement, the subject of a battle within the Trump administration—one that President Donald Trump’s most senior advisers are expected to resolve in the next few weeks (subscription).

Pruitt said that complying with the Paris Agreement means “contracting our economy to serve and really satisfy Europe and China and India. They are polluting far more than we are. We’re at pre-1994 levels with respect to our CO2 emissions.”

In total, only China emits more carbon dioxide than the United States, according to tracking data released by the World Resources Institute last week. Those data show that emissions from India and from the European Union are, respectively, one-half and two-thirds emissions from the United States. Moreover, on a per capita basis, the United States in 2015 produced two times more carbon dioxide emissions than China and eight times more than India.

How the Trump administration could actually exit the Paris Agreement, as Pruitt suggested, remains unclear. Under the agreement’s terms, it takes three years for a party to withdraw, followed by a one-year waiting period.

Pruitt followed up his interview with a proclamation of a new era of environmental deregulation in a speech at a coal mine fined for contaminating local waterways with toxic materials. There he said the EPA’s new “back to basics” agenda would give oversight of clean air and water to individual states and would bolster jobs in fossil fuel industries.

Study: Meeting Paris Agreement Goal Means World Has One Decade to Peak Emissions

The latest research establishing a timeline for phasing down fossil fuel consumption to limit global temperature rise to 1.5 degrees Celsius—the more stringent of the two Paris Agreement temperature goals—finds that global carbon dioxide emissions need to peak within 10 years (subscription).

Net emissions could peak by 2022, the study in the journal Nature Communications shows, under a “high-renewable” scenario in which wind, solar and bioenergy increase by some 5 percent annually.

Overall, the analysis produced by the International Institute for Applied Systems Analysis (IIASA) suggests that, by 2100, fossil fuel consumption must likely be reduced to less than a quarter of primary energy supply. But if carbon-capture-and-storage technology coupled with bioenergy production is found to be unfeasible, uneconomical or too burdensome on ecosystems, the analysis suggests that the world may have to rely heavily on nascent “negative emissions” technology.

The authors did note one other opportunity to rein in emissions, suggesting that land use and agriculture might absorb more carbon dioxide than their model considered.

“The study shows that the combined energy and land-use system should deliver zero net anthropogenic emissions well before 2040 in order to assure the attainability of a 1.5°C target by 2100,” said Michael Obersteiner, IIASA Ecosystems Services and Management Program director and study coauthor.

The study is one of the first published results from the newly developed—and freely available—FeliX model, a system dynamics model of social, economic, and environmental Earth systems and their interdependencies.

“Compared to other climate and integrated assessment models, the FeliX model is less detailed, but it provides a unique systemic view of the whole carbon cycle, which is vital to our understanding of future climate change and energy,” said Obersteiner.

The day after the IIASA study was published, the National Aeronautics and Space Administration released data showing that March ranked as the second hottest on record for the planet. It followed the second hottest February and third hottest January on record.

Energy Department Orders Grid Study

U.S. Department of Energy Secretary Rick Perry has ordered a 60-day study of the U.S. power grid to determine whether policies that favor wind and solar energy—including a recently renewed production tax credit that helps offset the cost of wind and solar installations and, in some states, renewable power mandates—are speeding the decline of baseload coal and nuclear power plants and potentially hampering grid reliability.

In an April 14 memo to his chief of staff, Perry wrote that grid experts have “highlighted the diminishing diversity of our nation’s electric generation mix and what that could mean for baseload power and grid resilience.”

The memo orders consideration of “the extent to which continued regulatory burdens, as well as mandates and tax and subsidy policies, are responsible for forcing the premature retirement of baseload power plants,” among other things.

Travis Fisher, a senior advisor in the Office of Energy Efficiency and Renewable Energy, has been tapped to head the study. Greenwire reported that Fisher has made several public statements through interviews, op-eds and blog posts in which he warned that federal regulations, the wind production tax credit and state renewable mandates were threatening grid reliability.

Electricity regulators are already examining how state policies might be affecting regional electricity markets and grid reliability, reports Bloomberg. Next month the Federal Energy Regulatory Commission (FERC) will hold a technical conference to consider state and federal jurisdictional battles over electricity markets, along with state programs that direct credits to renewable energy and zero-emission power.

In laying out her vision for the conference, FERC’s acting chair, Cheryl LaFleur, said that she hopes for a negotiated solution to wholesale power market issues.

“As I see it, there are three potential outcomes that we could achieve here, and the first is some kind of negotiated or planned solution—in my mind, the best option for stakeholders in different regions,” said LaFleur, who also mentioned litigation and re-regulation.

EPA Budget Cut Priorities Outlined in Internal Document

The Nicholas Institute for Environmental Policy Solutions at Duke University

An internal budget draft shows how the U.S. Environmental Protection Agency (EPA) proposes to meet Trump’s FY2018 Budget submission to Congress, which reduces EPA spending 31 percent.

The memo repeatedly portrays climate as outside the EPA’s core statutory requirements. It focuses instead on funding “core legal requirements,” scrapping 56 programs dealing with scientific research, climate change and education while sending other functions to state and local governments. One of those proposed cuts is to the program responsible for producing new car fuel economy labels and certifying that new vehicles, engines and fuels conform to clean air standards. Dubbed the Federal Vehicle and Fuels Standards and Certification program, it helped to uncover Volkswagen AG’s emissions cheating.

The agency’s budget also proposes to lay off 25 percent of EPA employees.

Asked about the budget in an interview with Fox News, EPA Administrator Scott Pruitt said that the agency expects states to assume a greater role in environmental protection.

“Over the last several years, there has been a lack of commitment to state partnership,” said Pruitt, adding that would change under his tenure (subscription).

But as Greenwire points out, much of that partnership is fueled by federal dollars, and Trump’s proposed EPA budget cuts, if implemented, could undermine Pruitt’s pledge to state environmental regulators.

Sent March 21 by Acting Chief Financial Officer David Bloom, the draft budget was addressed to the heads of EPA departments. They are supposed to provide feedback and explain how they would make the cuts but still fulfill statutory requirements. John Konkus, an EPA spokesperson, said that the agency is “working towards implementing the president’s budget based on the framework provided by his blueprint,” offering little else about the review process surrounding the draft.

Trump’s official budget is scheduled to go before Congress in mid-May.

Following Executive Order, Climate Rule Notices Published in Federal Register

President Donald Trump may not be finished issuing executive orders related to environment and energy, according to Mike McKenna, the former head of the Department of Energy transition team and founder of MWR Strategies.

“I don’t think we’re quite done with the executive orders,” said McKenna, speaking at the Energy Bar Association’s annual meeting in Washington (subscription). He noted that “offshore energy development” and “probably something clarifying where we are going with [the] Antiquities [Act]” could be next.

Last week, Trump signed a long anticipated executive order promoting fossil fuel extraction, greatly diminishing the role climate change plays in U.S. government decision making, and 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.

On Tuesday, notices announcing the review of Clean Power Plan as well as performance standards for        new fossil-fuel fired power plants and oil and gas facilities were published in the Federal Register. That step is the first in the rulemaking process to amend or rescind the rules. The EPA also withdrew its proposed rules for a federal plan to implement the Clean Power Plan. Those rules would have provided a template for states setting up their own regulations to meet the plan’s emissions reductions targets.

After Trump Executive Order, Others Seek to Provide Climate Leadership

President Donald Trump’s March 28 executive order formalizing his commitment to “unwind science-based climate action in the United States” would “relegate the United States to the bottom of the global climate action league,” according to a report released by Climate Action Tracker), a research coalition that rates all major nations on their pledges under the Paris Agreement, which is aimed at holding the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and at pursuing efforts to limit that increase to 1.5 degrees Celsius. The report finds that the order sets the United States on a trajectory to fall well short of its Paris Agreement commitment for 2025: instead of the 13 percent decrease from 2014 levels needed to meet that commitment, U.S. emissions in 2025 and 2030 would be roughly similar to today’s levels. But the report also finds that market pressures will continue the global clean energy transition.

Reacting to Trump’s executive order, which did not address the Paris Agreement, many nations acknowledged a vast investment shift from fossil fuels to clean energy and, notably, China, one of the world’s largest emitters, reaffirmed its commitment to the agreement.

All countries should “move with the times,” said Chinese Foreign Ministry Spokesman Lu Kang. “No matter how other countries’ policies on climate change, as a responsible large developing country China’s resolve, aims and policy moves in dealing with climate change will not change.”

Within the United States, Trump’s order elicited a similar sentiment by some cities and states.

“Climate change is both the greatest single threat we face, and our greatest economic opportunity for our nation,” the mayors of New York, Los Angeles, Houston and 72 other cities wrote in an open letter to the president. “That is why we affirm our cities’ commitments to taking every action possible to achieve the principles and goals of the Paris Climate Agreement, and to engage states, businesses and other sectors to join us.”

The Democratic governors of California, Connecticut, Minnesota, New York, Oregon and Washington, along with five mayors in those states, said in a statement that they would continue to lower carbon emissions despite conflicting policy from the Trump administration.

“Our commitment to limiting global average temperature increase to well below 2 degrees Celsius remains,” said the group. The signatories are members of the Under2 Coalition, a group of 167 cities, states and countries committed to reducing greenhouse gas emissions to 2 tons per capita, or 80–95 percent below 1990 levels by 2050.

Executive Orders Expected on Climate Rules as Trump Contemplates Paris Agreement Fate

The Nicholas Institute for Environmental Policy Solutions at Duke University

President Donald Trump is expected to sign an executive order directing the U.S. Environmental Protection Agency (EPA) to dismantle Obama-era climate rules, including the Clean Power Plan, which sets limits on carbon dioxide emissions from existing fossil-fuel fired power plants. Originally expected this week, GreenWire reports that according to a White House official the order “may be pushed beyond this week.”

It was unclear until now if the Trump administration would “repeal and replace” the Clean Power Plan, or just set upon a path to undo it, but the executive order will only call for the withdrawal of the regulation, according to sources (subscription). It could also instruct the Justice Department to effectively withdraw its legal defense of the climate rule in the U.S. Court of Appeals for the District of Columbia Circuit.

Like other executive orders recently signed by the president, this one would not, by itself, roll back the Clean Power Plan. Altering a final rule, like the Clean Power Plan, isn’t as simple as the stroke of a pen. It will likely require the EPA to undertake a new rulemaking process, including public notice and comment that could last a few years.

Unless Congress amends the Clean Air Act or the Supreme Court reverses prior opinions, the EPA retains its authority—and a legal obligation—to regulate greenhouse gases under the Clean Air Act. The question then becomes which Clean Air Act program is appropriate for the EPA to fulfill its legal obligation—the authority that underpins the Clean Power Plan or another provision of the Clean Air Act—and how the Trump administration believes that authority should be deployed in its discretion.

And while members of the Trump administration remain split on whether to follow through with campaign promises to withdraw from the Paris Agreement, the European Union (EU) pledged to “reinvigorate EU climate diplomacy … taking into account the latest developments and changing geopolitical landscape.” The EU may be looking to Canada to help ensure the agreement is implemented.

Oil and Gas Industry No Longer Required to Report Methane Emissions

U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt withdrew an Information Collection Request order issued by the Obama administration in November requiring the oil and gas industry to report information about their equipment and operations in an effort to rein in leaks of methane. The order, which took effect immediately, was the EPA’s first step to regulate methane emissions from the sector.

In November, the EPA sent letters to more than 15,000 owners and operators in the oil and gas industry requiring them to provide information on the numbers and types of equipment at onshore oil and gas production facilities, as well as information on methane emissions at the sites.

A letter sent to the EPA by the attorney generals of Alabama, Arizona, Kansas, Kentucky, Louisiana, Mississippi, Montana, Oklahoma, South Carolina and West Virginia expressed concern with the requirement, prompting the withdrawal.

“By taking this step, EPA is signaling that we take these concerns seriously and are committed to strengthening our partnership with the states,” Pruitt said. “Today’s action will reduce burdens on businesses while we take a closer look at the need for additional information from this industry.”

Senate Approves Rick Perry as Energy Secretary, Ryan Zinke as Interior Lead

Last week, the U.S. Senate confirmed two department heads who will have considerable influence on how the country approaches energy issues from funding of advanced energy projects to use of public lands for oil and gas extraction.

In a 62–37 vote, Rick Perry was confirmed as head of the U.S. Department of Energy, the agency he vowed to eliminate during his failed 2012 presidential bid and at the helm of which he faces tough issues related to regulatory reach, efforts to mitigate climate change, and potentially deep cuts in agency staffing and spending. He now is responsible for maintenance of the nation’s nuclear arsenal and 17 national laboratories that conduct research into energy technologies that could help fight climate change, a phenomenon he has questioned. During his confirmation hearings he acknowledged that human activity has contributed to warming, a sharp pivot from the global cooling cover up he advanced in his 2010 book, Fed Up! Our Fight to Save America from Washington.

As governor of Texas, Perry presided over big increases in his state’s wind power and shale oil drilling. During his Senate confirmation hearing, he said he would seek to develop American energy in all forms—oil, gas, nuclear, and renewable—and that he would rely on federal scientists to pursue “sound science.”

He replaces Ernest Moniz, a nuclear physicist who led technical negotiations in the 2015 Iran nuclear deal and successor of Steven Chu, a Nobel Prize-winning physicist.

By a vote of 68 to 31, former Montana Rep. Ryan Zinke was confirmed as secretary of the Department of the Interior, where he assumes oversight of 500 million acres of public land, including 59 national parks. Zinke, who has questioned climate science and expressed support for expanding mining and oil and gas development on public land, will now head up the National Park Service, the U.S. Geological Survey, the Bureau of Reclamation and the Bureau of Indian Affairs.

During Senate committee hearings on his nomination last month, Zinke said one of his first priorities would be to fix deteriorating infrastructure at parks under the National Park Service. But he gave little clue about how he would act on other issues as head of the department whose agencies decide how resources such as coal are managed and which animals are eligible for listing under the Endangered Species Act.

He did say that federal land should be managed under a multiple-use model that allows hiking, hunting, fishing and camping along with timber harvesting, coal mining and oil and natural gas drilling.

Meanwhile, one of Trump’s confirmed cabinet members, Scott Pruitt, who was approved by the Senate last month and sworn in as EPA administrator,

Clean Air Act, Other Environmental Regulations Potentially Targeted by New Executive Order

The Nicholas Institute for Environmental Policy Solutions at Duke University

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).
