Last month, a 24-state coalition led by Texas and West Virginia state attorneys general—leading litigators in the fight against the Clean Power Plan—penned a letter to President-Elect Donald Trump asking him to issue an order to stop working to enforce the rule to reduce emissions from existing power plants. More recently, officials from states and several cities have sent a letter countering this earlier advice, and instead urged Trump to preserve the rule and continue defending it in court.
The Clean Power Plan is presently stayed while a 10-judge panel reviews a legal challenge. A decision from the D.C. Circuit Court of Appeals’ rare “en banc” review is expected this year.
“We advocate that you reject misguided advice that the Clean Power Plan be discarded; advice that, if followed, would assuredly lead to more litigation,” the latest letter reads. “Instead, we urge you to support the defense of this critically-important rule and the implementation of its carefully constructed strategies to reduce emissions from the nation’s largest sources.”
If politics or litigation forces the U.S. Environmental Protection Agency (EPA) to use other authorities under the Clean Air Act to regulate greenhouse gas emissions, a new working paper by Duke University’s Nicholas Institute for Environmental Policy Solutions and the University of North Carolina’s Center for Climate, Energy, Environment, and Energy says the EPA might consider using the National Ambient Air Quality Standards (NAAQS) program.
“The language of the Clean Air Act gives the EPA a lot of flexibility to enact a program for greenhouse gases,” said Christina Reichert, a Nicholas Institute policy counsel who co-authored the paper.
The paper examines the opportunities and challenges associated with regulation of greenhouse gases under the NAAQS program, drawing a comparison with the Clean Power Plan’s approach under a different section of the Clean Air Act. Though a program under NAAQS wouldn’t mirror the Clean Power Plan, it could support many of its key provisions, including trading-ready plans. Although use of the NAAQS program would present challenges—such as permitting small sources—it is feasible, say the paper authors.
Climate Policy and Trump
In December, the Electoral College confirmed the presidency of Donald Trump. With just weeks before his inauguration, ClimateWire took a look back at the Paris Agreement, the Clean Power Plan, and other highlights of climate policy in 2016, and other media outlets contemplated what 2017 holds.
Mongabay’s Mike Gaworecki lays out eight issues to watch, including whether the Trump administration will withdraw from the Paris Climate Agreement. And Nicholas Institute, Harvard, and University of North Carolina researchers outlined six key areas of federal policy and, for each area, identified the issues Trump must address that will shape the future of the electricity sector. This month, we’re awaiting Senate hearings for some of Trump’s environmental picks—Scott Pruitt (presently slated to lead the EPA) and Rex Tillerson (tapped as secretary of state).
Study: Flood Risk Pattern Changing with Warming Climate
According to research published in the journal Geophysical Research Letters, the threat of flooding in the northern half of the United States is growing as the Earth warms.
Using stream gauge data and satellite images, two University of Iowa scientists found that this pattern is likely due to shifting rainfall patterns and the amount of water in the ground. The study’s 2,042 stream gauge readings between 1985 and 2015 showed a measurable increase in the number of flood events in the north over the last 30 years.
“It’s almost like a separation where generally flood risk is increasing in the upper half of the U.S. and decreasing in the lower half,” said study co-author Gabriele Villarini in reference to the finding that satellite data showed groundwater increasing in the north and decreasing in the Southwest and western U.S., regions that are experiencing prolonged droughts. “It’s not a uniform pattern, and we want to understand why we see this difference.”
Although the authors have yet to identify the reasons that some areas are getting more, or less, rainfall than others, they believe that rains may be redistributed as regional climate changes.
The researchers hope that their findings could change communication of changing flood patterns, which typically have been described in terms of stream flow, or the amount of water flowing per unit of time.

The possible energy agenda for U.S. President-elect Donald Trump is described in a memo prepared by Trump’s energy transition head Thomas Pyle, the president of the American Energy Alliance and the Institute for Energy Research. It highlights a “pro-energy and pro-market policies” agenda. At the top of the list of 14 policy changes is withdrawal from the Paris Agreement—the international agreement to limit global warming by cutting global carbon emissions—and the Clean Power Plan, which aims to reduce emissions from existing U.S. power plants.
“In response to Massachusetts v. EPA, the Obama administration found that greenhouse gas emissions harmed human health and welfare,” the memo states. “This is the regulatory predicate to the Obama administration’s Corporate Average Fuel Economy (CAFE) mandates and Clean Power Plan and greatly expanded EPA’s power. This finding will be reconsidered and possibly revoked, marking a major blow to underpinning for many climate regulations.”
Also targeted in the memo is lifting of the coal lease moratorium, expediting approvals of LNG export terminals, moving forward with pipeline infrastructure, reassessing the environmental impacts of wind energy, reducing energy subsidies, amending the Renewable Fuel Standard, increasing federal oil and natural gas leasing and relaxing the federal fuel economy standards. Ending federal agencies’ use of the social cost of carbon—an estimate of the damage avoided from marginal reductions of carbon dioxide—when weighing the costs and benefits of new energy and environmental regulations is also mentioned.
“The Obama administration aggressively used the social cost of carbon (SCC) to help justify their regulations,” the memo states. “During the Trump Administration the SCC will likely be reviewed and the latest science brought to bear. If the SCC were subjected to the latest science, it would certainly be much lower than what the Obama administration has been using.”
The social cost of carbon also came up in another document suggestive of the future of U.S. energy policy—a questionnaire sent by Trump’s transition team to the Department of Energy that asked agency officials to identify employees and contractors who have played a role in promoting President Obama’s climate agenda, including those who worked on forging the Paris Agreement and on domestic efforts to cut the nation’s carbon output and those who attended interagency meetings on the social cost of carbon.
Among the transition’s requests in the 74-item questionnaire, reports NPR, are e-mails about domestic and international climate talks, money spent on loan-guarantee programs for renewable energy, and names of the 20 highest-paid employees at the DOE’s national laboratories. The Energy Department on Tuesday said it would not comply with requests for names.
Trump Nominates Tillerson as Secretary of State; Perry to Lead Department of Energy
On Tuesday, U.S. President-elect Donald Trump nominated Exxon Mobil Corp. CEO Rex Tillerson to lead the Department of State—the most senior U.S. diplomat position, one responsible for enacting the U.S. government’s foreign policy (subscription).
“Mr. Tillerson knows how to manage a global organization and successfully navigate the complex architecture of world affairs and diverse foreign leaders. As Secretary of State, he will be a forceful and clear-eyed advocate for America’s vital national interests, and help reverse years of misguided foreign policies and actions that have weakened America’s security and standing in the world,” said Trump of the Texas native who has been with Exxon since graduating from the University of Texas in 1975.
The 64-year-old Tillerson has no experience in government or working as a diplomat and his position on climate change may be left of Trump’s. As the Washington Post reports, Exxon understood the connection between greenhouse gas emissions and fossil fuels in the 70s but only fairly recently (under Tillerson’s watch) did the company publicly acknowledge the link.
For Tillerson to win Senate approval of his nomination, he will need to counter some concerns from lawmakers in both parties about ties to Russia and its President Vladimir Putin. Specifically, some have expressed unease about his opposition to U.S. sanctions in Russia, which awarded him a friendship medal in 2013.
Also, on Tuesday, Rick Perry, former Texas governor, was tapped to head the Department of Energy as secretary. Perry, who once said he would eliminate the department when he ran for president in 2012, would replace Ernest Moniz, who has been energy secretary under the Obama administration since 2013.
Arctic Report Card: Warming Continues
“We’ve seen a year in 2016 in the Arctic like we’ve never seen before,” said Jeremy Mathis, director of NOAA’s Arctic Research Program. The year showed “a stronger, more pronounced signal of persistent warming than any other year in our observation record.”
What changes are scientists observing? To name a few: The spring snow cover this year in the North American Arctic was the lowest since the satellite record began in 1967, and the average surface air temperature for the year ending September 2016 is by far the highest since 1900. Scientists are seeing temperature spikes during months when little, if any, sunshine is reaching the surface of the Arctic.
“Those are the periods when the Arctic should be really cold,” Mathis said. “It’s one thing for the summers to be warmer, but this is [a new] trend of the winter months setting record temperatures.”
And due to water temperatures that are colder than those further south, the Arctic Ocean is especially prone to ocean acidification. The report describes how Arctic sea ice has become younger and thinner, causing patches of dark open water to absorb more solar rays that warm the water.
It indicates the changes are influenced by long-term increases not only in global carbon dioxide, but also in air temperatures—as well as with natural seasonal and regional variability.

Just a few weeks after U.S. President-Elect Donald Trump, a critic of climate change science, told New York Times journalists he had an “open mind” on climate change, he and his daughter Ivanka met with former vice president and climate advocate Al Gore.
“I had a lengthy and very productive session with the president-elect,” said Gore of Trump. “It was a sincere search for areas of common ground. I had a meeting beforehand with Ivanka Trump. The bulk of the time was with the president-elect, Donald Trump. I found it an extremely interesting conversation, and to be continued.”
Though Trump and Gore’s topic of discussion wasn’t directly referenced in his statement, it is speculated that climate change was on the list. The Washington Post reports that an aide to Gore, who spoke on the condition of anonymity, said the former vice president “made clear in his statements following the election that he intended to do everything he could to work with the president-elect to ensure our nation remains a leader in the effort to address the climate crisis.”
Regarding the meeting with Ivanka, however, Gore was more forthcoming.
“It’s no secret that Ivanka Trump is very committed to having a climate policy that makes sense for our country and for our world,” Gore said. “And that was certainly evident in the conversation that I had with her before the conversation with the President-elect.”
Trump’s EPA: Leader Tapped
U.S. President-Elect Donald Trump has tapped Oklahoma Attorney General Scott Pruitt to replace current U.S. Environmental Protection Agency (EPA) Administrator Gina McCarthy. The nomination seems to follow with Trump’s campaign promises to rollback EPA regulations.
“For too long, the Environmental Protection Agency has spent taxpayer dollars on an out-of-control anti-energy agenda that has destroyed millions of jobs, while also undermining our incredible farmers and many other businesses and industries at every turn,” said Trump in a statement. “As my EPA Administrator, Scott Pruitt, the highly respected Attorney General from the state of Oklahoma, will reverse this trend and restore the EPA’s essential mission of keeping our air and our water clean and safe.”
Pruitt, whose biography indicates he is a “leading advocate against the EPA’s activist agenda,” offered that he intends to run the EPA in a way that “fosters both responsible protection of the environment and freedom for American businesses.”
Pruitt was one of two rumored candidates for this post who have called for significant rollbacks in regulations. He has sued the EPA over its regulations to reduce greenhouse gas emissions from power plants under the Clean Air Act. In an interview with Reuters in September, Pruitt said that he sees the Clean Power Plan as a form of federal “coercion and commandeering” of energy policy and that his state should have “sovereignty to make decisions for its own markets.”
Warming Could Dramatically Increase Soil Carbon Losses
A study published last week in the journal Nature documents how carbon loss in soil worsens climate change. The 25-year study finds that as the planet warms, the respiration of microorganisms in soils increases, releasing greenhouse gases such as carbon dioxide and methane. The scientists’ compilation of 49 empirical studies of soil carbon emissions from plots around the world revealed that climate change will lead to the loss of at least 55 trillion kilograms of carbon from the soil by mid-century.
“It’s of the same order of magnitude as having an extra U.S. on the planet,” said Thomas Crowther, a co-author with the Netherlands Institute of Ecology.
The study found that carbon losses will be greatest in colder places at high latitudes and altitudes—places that have massive carbon stocks but that have largely been missing from previous research.
Correction: In last week’s story about an Arctic Council report on climate and other changes in the Arctic, we should have said that temperatures in the region had reached 9–12 degrees Celsius (16–22 degrees Fahrenheit) above seasonal averages.
The Climate Post offers a rundown of the week in climate and energy news. It is produced each Thursday by Duke University’s Nicholas Institute for Environmental Policy Solutions.
Climate-change-related environmental, ecological, and social changes in the Arctic are accelerating and are more extreme than ever recorded, undermining the sustainability of current ways of life in the region and potentially destabilizing climate and ecosystems around the world, according to a five-year report released last week by the Arctic Council, an intergovernmental organization formed to protect the region.
“Arctic social and biophysical systems are deeply intertwined with our planet’s social and biophysical systems, so rapid, dramatic and unexpected changes in this sensitive region are likely to be felt elsewhere,” the report states. “As we are often reminded, what happens in the Arctic doesn’t stay in the Arctic.”
The report noted that the Greenland Ice Sheet, which was thought to be resistant to climate change, is experiencing higher-than-expected thinning “over time scales of only years” due to warmer temperatures caused by climate change and that if it melts completely, global sea levels would rise an average of 7.4 meters.
The report outlines 19 “regime shifts” under way or on the horizon absent efforts to halt them. They range from sea-ice-free summers to ocean circulation changes and collapse of some Arctic fisheries.
“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the co-authors of the report. “[These developments] also make the potential for triggering [tipping points] and feedback loops much larger.”
Trump Transition: EPA Prospects
Just days after stating his “open mind” to confronting climate change, president-elect Donald Trump was meeting with potential prospects to run the U.S. Environmental Protection Agency (EPA) that would align with his campaign promises to roll back agency regulations.
Two rumored EPA leaders who have called for a significant rollback in regulations—Oklahoma Attorney General Scott Pruitt and former Texas environmental regulator Kathleen Hartnett White—were scheduled to meet with Trump this week.
In an interview with McClatchy, White confirmed her consideration for the post, which she says she would take on with a new approach to address a “shifting environmental landscape.” White also shared details of her conversation with Trump.
“He wants the EPA to run more carefully, to use stronger science and be unabashedly conscientious to the effect of more and more rules on existing employment and job creation,” she said. “I have no desire to put words in his mouth. But as he is in other areas, he likes a good deal.”
Climate Change Conference in Marrakech Concludes
The United Nations Framework Convention on Climate Change (COP22), which brought nearly 200 countries together to hammer out the details of last year’s Paris Agreement, concluded last month. What exactly came out of the two-week conference?
- A timeline for implementing the Paris Agreement, which aims to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. Countries participating in COP22 decided to complete detail setting for the agreement by 2018 and to review progress in 2017.
- The Marrakech Action Proclamation. The one-page document reaffirms countries’ commitments to the Paris Agreement’s goals following the election of Donald Trump as the next U.S. president. On the campaign trail, Trump stated intentions to end U.S. involvement in the agreement.
- Forty-eight of the world’s poorest and most vulnerable countries pledged to turn in more ambitious targets to Paris before 2020 and to shift to 100 percent renewable energy use by 2050.
- An agreement to continue the discussion on climate finance. There’s still uncertainty surroundingthe pathway to mobilizing $100 billion in climate finance for developing countries by 2020, to establishing rules for reporting finance, and to scaling up adaptation finance.
- Nations also agreed on a five-year work-plan on “loss and damage” to address issues beyond climate adaptation like slow-onset impacts of climate change, non-economic losses and migration.
Editor’s Note: The Climate Post will not circulate next week, Thursday, November 24, in observance of the Thanksgiving holiday. It will return Thursday, December 1.
A speech by U.S. Secretary of State John Kerry during the second week of the United Nations Framework Convention on Climate Change (COP22) focused, in part, on president-elect Donald Trump and his views on climate change. He tried to dispel doubts about the new U.S. government’s policies, saying it is a little bit “different when you’re actually in office compared to when you’re on the campaign trail.”
“The president-elect is going to have to make his decision,” said Kerry of Trump, who vowed while campaigning to withdraw the United States from the global Paris Agreement now under negotiation at COP22. “What I will do is speak to the assembly about our efforts and what we’re engaged in and why we’re engaged in it, and our deep commitment as the American people to this effort.”
He noted that the United States “is on our way to meeting all of our climate commitments,” and that the primary driver of emissions reduction is marketplace forces. “Investing in clean energy simply makes economic sense … [clean energy] is a multi-trillion dollar market, the largest the world has ever known.”
But he also acknowledged that even though the Paris Agreement came into force Nov. 4, there is no guarantee that its critical goals—holding the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and pursuing efforts to limit that increase to 1.5 degrees Celsius—will be met. He noted that, although government leadership will be essential, governments alone won’t solve the climate crisis and that private industry is more important than ever.
“And if we fall short, it will be the greatest instance in modern history of a generation in a time of crisis, abdicating responsibility for the future,” Kerry said. “And it won’t just be a policy failure; because of the nature of this challenge, it will be a moral failure, a betrayal of devastating consequence.”
CO2 Emissions from Fossil Fuels, Industry Flattening
A new study suggests that for the third consecutive year carbon dioxide emissions from fossil fuels and industry have risen negligibly amid global economic growth, a slowdown driven by China. According to the study released at United Nations talks on climate change in Marrakesh, Morocco, and published in the journal Earth System Science Data, these emissions will grow by just 0.2 percent overall this year but will continue to rise in emerging economies.
“2016 we estimate to be flat again,” said Glen Peters, one of the contributors to the research and a scientist at the Center for International Climate and Environmental Research-Oslo in Norway. “It’s definitely three years, it’s fairly flat, which is quite a contrast to a decade ago, when it was growing at about 3 percent. It’s really leveled out the last few years.”
The decrease in Chinese emissions is particularly significant because China is the world’s biggest carbon emitter, accounting for some 30 percent of the world’s annual global emissions, though whether that decrease is due mainly to economic troubles or to environmental efforts is uncertain.
Like Chinese emissions, U.S. emissions have also fallen, a downward trend that began in 2007. According to the study, they were down 2.5 percent in 2015 and are projected to drop 1.7 percent this year due to lowered demand for coal.
Nevertheless, the leveling off falls short of the reductions called for in the Paris Agreement, implementation details of which are being hammered out during the second week of the U.N.’s COP22 in Marrakech.
“The break in emissions rise is a great help for tackling climate change but it is not enough,” said Corinne Le Quéré, director of the Tyndall Centre at University of East Anglia and primary study author. “Global emissions now need to decrease rapidly, not just stop growing. If climate negotiators in Marrakech can leverage ambitions for further cuts in emissions, we could be making a serious start to addressing climate change.”
According to a new International Energy Agency (IEA) report, implementing current international pledges will slow the projected rise in carbon emissions from 650 million tons per year in 2000 to 150 million tons in 2040 but put the world far off the Paris Agreement goals.
“While this (reduction) is a significant achievement, it is far from enough to avoid the worst impact of climate change as it would only limit the rise in average global temperatures to 2.7 (degrees Celsius) by 2100,” said the IEA.
Study Says Climate Change is Altering Earth’s Ecological Systems
A new study in the journal Science suggests that climate change is already having an impact on 82 percent of global ecological systems—affecting everything from genes to entire ecosystems. This impact could increase disease outbreaks and threaten food security.
“There is now clear evidence that, with only a ~1 degree C of warming globally, very major impacts are already being felt,” said co-author Brett Scheffers of the University of Florida. “Genes are changing, species’ physiology and physical features such as body size are changing, species are rapidly moving to keep track of suitable climate space, and there are now signs of entire ecosystems under stress.”
The study also indicates that the adaptive capacity in wildlife could be used applied to crops, livestock and fisheries.
“The level of change we have observed is quite astonishing considering we have only experienced a relatively small amount of climate change to date,” said study co-author James Watson from the Wildlife Conservation Society and University of Queensland. “It is no longer sensible to consider this a concern for the future. Policy makers and politicians must accept that if we don’t curb greenhouse gas emissions, an environmental catastrophe is likely.”
This study comes as nations discuss the Paris Agreement and the need to plan for its implementation.
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
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.
Climate change has entered a new phase, said the United Nations World Meteorological Organization (WMO) on Monday. The WMO reported that concentrations of carbon dioxide (CO2) “surged again to new records in 2016,” and it predicted that the annual average for CO2 would remain above 400 parts per million (ppm), 44 percent higher than before the Industrial Revolution, for generations.
The 400 ppm threshold, a symbolic red line in the methodical march of greenhouse gas concentrations, was continuously breached for the first time in 2015—a rise driven largely by fossil fuel emissions and aided by a strong El Niño, which “triggered droughts in tropical regions and reduced the capacity of sinks like forests, vegetation and the oceans to absorb CO2,” the WMO said. Last year’s jump in carbon dioxide was the largest annual increase on record (subscription).
“The year 2015 ushered in a new era of optimism and climate action with the Paris climate change agreement,” said WMO Secretary-General Petteri Taalas. “But it will also make history as marking a new era of climate change reality with record high greenhouse gas concentrations.” “The El Niño event has disappeared. Climate change has not . . . Without tackling carbon dioxide emissions, we cannot tackle climate change and keep temperature increases to below 2 degrees Celsius above the pre-industrial era. It is therefore of the utmost importance that the Paris Agreement does indeed enter into force well ahead of schedule on 4 November and that we fast-track its implementation.”
Taalas added that improvements in the climate will be seen by 2060 if countries begin to lower their carbon dioxide emissions now.
Between 1990 and 2015, Earth experienced a 37 percent increase in radiative forcing—the warming effect on the climate—because of greenhouse gases from industrial, agricultural, and domestic activities, according to the WMO.
WMO’s announcement comes within a week of the National Aeronautics and Space Administration’s report that found September was the 11th consecutive month to set record high temperatures.
Study: Glacier Melt in Antarctica Could Help Predict Global Sea Level Rise
A number of research studies have suggested Antarctica’s ice is melting faster than previously thought, but two new studies may help better predict future Antarctica ice loss and global sea level rise. The studies examined the Pope, Kohler, and Smith glaciers—part of the Dotson and Crosson ice shelves—in West Antarctica.
“Our primary question is how the Amundsen Sea sector of West Antarctica will contribute to sea level rise in the future, particularly following our observations of massive changes in the area over the last two decades,” said University of California Irvine’s Bernd Scheuchl, lead author on the first of the two studies published in the journal Geophysical Research Letters. “Using satellite data, we continue to measure the evolution of the grounding line of these glaciers, which helps us determine their stability and how much mass the glacier is gaining or losing. Our results show that the observed glaciers continue to lose mass and thus contribute to global sea level rise.”
A second study published Tuesday in the journal Nature Communications found that a significant portion of Antarctica is subject to “intense unbalanced melting” revealing high rates of ice loss from glaciers’ undersides. It also blames receding glacial grounding lines for the ice loss—spurred by an influx of warm ocean water beneath the ice shelves.
The glacier that saw the most melt, the study says, was Smith. It lost about 1,000 feet of ice between 2002 and 2009, which authors think is “a strong piece of evidence” that these glaciers, along with the larger Amundsen region, were subjected to a large influx of warm ocean water during that period.
“If I had been using data from only one instrument, I wouldn’t have believed what I was looking at, because the thinning was so large,” said author Ala Khazendar, a researcher at NASA’s Jet Propulsion Laboratory, noting how the work shows how important it is to understand both the ocean circulation and seabed topography when determining future melt and sea level rise.
IEA: Significant Renewables Growth Expected by 2021
The renewable energy market is growing around the world, according to a study by the International Energy Agency (IEA). IEA raised its estimate of the amount of renewable energy on power grids 13 percent from its 2015 forecast. It forecasts a 825 gigawatt boost in capacity by 2021 (a 42 percent increase from today).
“We are witnessing a transformation of global power markets led by renewables and, as is the case with other fields, the center of gravity for renewable growth is moving to emerging markets,” said IEA Executive Director Fatih Birol.
The growth will mostly be driven by four countries: China, the U.S., India and Mexico. China is the leader.
“About half a million solar panels were installed every day around the world last year,” according to the report. “In China, which accounted for about half the wind additions and 40 percent of all renewable capacity increases, two wind turbines were installed every hour in 2015.”
In the United States over the next five years, renewable capacity is forecast to grow to 328.2 gigawatts from 221.1 gigawatts. During this period, solar PV is forecast to nearly triple—from 26.1 gigawatts to 77.5 gigawatts—and wind to grow nearly 71.5 percent.
“Renewables are and still remain dependent on policies … to create the right market rules and the right framework to attract investments,” said Paolo Frankl, head of the IEA’s renewable energy division.
Thirty-one new countries formally agreed to join the Paris Agreement to reduce global emissions—bringing the total committed countries to 60. The Paris Agreement takes effect when it is formally adopted by at least 55 countries representing at least 55 percent of global greenhouse gas emissions. Yet, so far, these 60 country commitments only account for 48 percent of total global emissions.
Among the 31 countries who committed this week during Climate Week—a meeting in New York of international business and government leaders to examine progress toward meeting Paris Agreement goals—were Brazil, the world’s seventh largest emitter of greenhouse gases, Mexico, Argentina, Sri Lanka, United Arab Emirates, Kiribati and Bangladesh.
“Today we also heard commitments from many other countries to join the agreement this year. Their combined emissions will take us well past the required amount for the agreement to enter into force,” said Secretary General Ban Ki-Moon. “I am convinced that the Paris Agreement will enter into force before the end of 2016.”
Germany, Austria, Australia, and the United Kingdom are among the countries planning to formally join the agreement by the end of 2016.
“And in a demonstration of our commitment to the agreement reached in Paris, the U.K. will start its domestic procedures to enable ratification of the Paris agreement, and complete these before the end of the year,” said U.K. Prime Minister Theresa May.
Ban Ki-Moon said he hopes the agreement, which aims to limit the global temperature rise to 2 Celsius above pre-industrial levels with an aspiration of keeping it to 1.5 Celsius, can come into force by the 22nd Conference of Parties in Marrakesh, Morocco, in November 2016.
Arctic Sea Ice Hits Second-Lowest Summer Measurement
Arctic ice levels have shrunk to their second-lowest recorded level, tying the 2007 minimum extent, according to a new report released by the National Aeronautical Space Administration (NASA)-supported National Snow and Ice Data Center (NSIDC). On September 10, ice covered just 1.6 million square miles; the lowest level, 1.31 million square miles, was recorded September 17, 2012. Satellites have observed a trend of marked decrease since 1979.
“September Arctic sea ice is now declining at a rate of 13.4 percent per decade, relative to the 1981 to 2010 average,” NASA says.
According to NSIDC, all 10 of the lowest summer extents in the satellite record have occurred in the past 10 years. NASA, which released an animation depicting the evolution of the Arctic sea ice cover in 2016 from its wintertime maximum extent to its apparent yearly minimum, has called this pattern the “new normal” for Arctic ice.
“It was a stormy, cloudy, and fairly cool summer,” said NSIDC Director Mark Serreze. “Historically, such weather conditions slow down the summer ice loss, but we still got down to essentially a tie for second lowest in the satellite record.”
NSIDC scientists suspect that the unusually thin sea ice pack melted from below by unusually mild ocean waters and that the ice loss may have been accelerated by a particularly notable late August ice breakup triggered by powerful storms.
“We’ve always known that the Arctic is going to be the early warning system for climate change,” Serreze said. “What we’ve seen this year is reinforcing that.”
He added that sometime in the next few decades the Arctic Ocean is headed for ice-free summers.
Poll Says Americans Care about Climate Change
Sixty-five percent of Americans think climate change is a problem that the government needs to address, according to a new survey by the Energy Policy Institute at the University of Chicago and the Associated Press-NORC Center for Public Affairs Research. Of those polled, 57 percent would pay at least $1 month, 39 percent would pay $10 a month and 20 percent would pay $50 a month to combat it.
Nearly 8 in 10 of the poll’s nearly 1,096 respondents indicated that the U.S. should maintain its commitment under the Paris Agreement to reduce global emissions, even if other countries do not. The United States has committed to reduce its greenhouse gas emissions by 26-28 percent below the 2005 level in 2025, and to make “best efforts” to reduce emissions by 28 percent.
Surveys conducted by Yale University and George Mason University suggest that 17 percent of Americans view climate change as an alarming threat and that another 28 percent are concerned about climate change but view it as a distant threat.
The subject has become highly contentious since 1997, when then Vice President Gore helped broker an international treaty, the Kyoto Protocol, to reduce heat-trapping gases from the burning of coal, oil and gas. The U.S. later withdrew from the treaty.
“And at that moment the two parties began to divide,” said Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, who was involved in the surveys. “They begin to split and go farther and farther and farther apart until we reach today’s environment where climate change is now one of the most polarized issues in America.”
Climate change will again be in the spotlight as a group of climate scientists gather in Switzerland to discuss a United Nation’s report expected to detail the impacts of 1.5 degrees Celsius of warming. In Paris last year, some 190 countries pledged to hold the global average temperature increase to “well below” 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit that increase to 1.5 degrees Celsius. But there are scientific questions not only about the costs and benefits of keeping warming to 1.5 degrees Celsius, but also about how to remain on a 1.5 C pathway. The Huffington Post shows what the Paris Climate Agreement is up against in a series of charts.
What we do know is this decade is the critical decade for action.
“The risks of future climate change—to our economy, society and environment—are serious, and grow rapidly with each degree of further temperature rise,” the Australian government’s Climate Commission wrote in a report. “Minimising these risks requires rapid, deep and ongoing reductions to global greenhouse gas emissions. We must begin now if we are to decarbonize our economy and move to clean energy sources by 2050. This decade is the critical decade.”
And the Host City of the Summer 2084 Games Is . . .
A study published in The Lancet says that only three North American cities—San Francisco, Calgary, Vancouver—will have a climate sufficiently cool and stable to host the Summer Olympic games in 70 years. The authors, who considered only cities in the northern hemisphere, where 90 percent of the world’s population lives, and only those with a population greater than 600,000 in 2012, the lower limit of host cities since World War II, said that climate change would make most of the 645 cities unsafe venues due to rising temperatures and humidity caused by climate change.
“You could take a risk, and plan your Olympics, and maybe not get the hot days you expect, but that would be a big risk when there are many billions of dollars at stake,” said Kirk Smith, a researcher at the University of California–Berkeley’s School of Public Health and the lead author of the study.
To measure the suitability of future Olympics sites, the researchers used climate change projections and a “wetbulb” globe temperature—a measurement reflecting the combination of humidity, heat radiation, temperature, and wind. They picked 2085 as a target date and as their target event what they considered the Olympics’ most physically challenging outdoor endurance event: the marathon. They selected 82.5 degrees Fahrenheit as the “high-risk” temperature for marathoners.
“The findings indicate that by 2085, Istanbul, Madrid, Rome, Paris and Budapest—all cities that are or were in contention for either the 2020 or 2024 Summer Olympics—would be unfit to host the games,” the authors said. “Tokyo, the city that has secured the 2020 summer Olympiad, would also be too hot to ensure athlete safety, should these projections come to pass.”
Which cities would be viable hosts? None in Latin America or Africa, 25 in western Europe, 5 in eastern Europe and Asia, and 3 in North America.
“If the world’s most elite athletes need to be protected from climate change, what about the rest of us?” the study concludes.
One of the most startling implications of the research is that temperatures will be too high for laboring outdoors, where half the world’s population works.
Truck Emissions Limits Set
New emissions requirements affecting heavy- and medium-duty vehicles, which represent only about 5 percent of total highway traffic but account for 20 percent of transportation-related fuel consumption and carbon emissions, were announced this week. The requirements call for as much as a 25 percent reduction in carbon emissions and fuel consumption in certain models by 2027. It also requires annual increases in efficiency of 2.5% from 2021-2027 for heavy-duty pickup trucks and vans.
“The standards promote a new generation of cleaner, more fuel-efficient trucks by encouraging the development and employment of new and advanced cost-effective technologies through model year 2027,” said Gina McCarthy, administrator of the U.S. Environmental Protection Agency (EPA), which developed the new rules in conjunction with the National Highway Traffic Safety Administration. “These standards are ambitious and achievable, and they will help ensure the American trucking industry continues to drive our economy — and at the same time protect our planet.”
Official say the new requirements are expected to cut 1.1 billion metric tons of carbon emissions through the next decade and represent a global benchmark for reducing vehicle-exhaust pollutants linked to climate change.
Coral in every major reef region across the world has already experienced bleaching, and the National Oceanic and Atmospheric Administration (NOAA) forecasts that temperatures in much of the Pacific, Atlantic and Indian oceans could reach a point at which significant bleaching of corals is present this summer. NOAA’s Coral Reef Watch suggests that the greatest threat is to reefs in Palau and the Federated States of Micronesia. All Northern Hemisphere U.S.-coral reefs are on alert for bleaching.
In a statement, NOAA said that “This third global bleaching event began in mid-2014” and is ongoing. “Global warming, coupled with intense El Nino, continues to make this the longest and most widespread coral bleaching event on record.”
Coral bleaches when it becomes damaged or diseased by rising water temperatures. Some recent studies have suggested other factors—beyond just warming water—also play a role. Over the past century, climate change has already caused global sea surface temperatures to rise by about 1 degree Celsius, pushing corals closer to their bleaching threshold.
Although the bleaching event was already the longest in recorded history and was predicted to run past the middle of the year, NOAA’s latest climate model-based forecasts suggest it will run at least through the end of 2016.
“It’s time to shift this conversation to what can be done to conserve these amazing organisms in the face of this unprecedented global bleaching event,” said Jennifer Koss, NOAA’s Coral Reef Conservation Program director. “We have boots on the ground and fins in the water to reduce local stressors. Local conservation buys us time, but it isn’t enough. Globally, we need to better understand what actions we all can take to combat the effects of climate change.”
This month, NASA launched a new, three-year project—Coral Reef Airborne Laboratory (CORAL)— to study the Pacific Oceans coral reefs by aircraft from 23,000 feet above the ocean. NASA scientists plan to map large swaths of coral in hopes of better understanding how environmental changes—including climate change, acidification, and pollution—are affecting these delicate ecosystems.
“CORAL will provide the most extensive picture to date of the condition of a large portion of the world’s coral reefs from a uniform data set,” NASA’s Jet Propulsion Lab penned in a press release. “The data will reveal trends between coral reef condition and biogeophysical forcings, both natural and those arising from human activities. With this new understanding of reef condition, we can better predict the future of this global ecosystem.”
White House Announces Energy Storage Projects
At a summit of regulators, power companies, municipalities, and energy developers on Monday, the Obama administration announced new executive actions and 33 state and private sector commitments to “accelerate the grid integration of renewable energy and storage.” Collectively, the commitments—aimed at reducing carbon emissions and increasing the resilience of the electricity grid—are expected to result in at least 1.3 gigawatts of additional storage procurement or deployment over five years and could lead to approximately $1 billion in energy storage investments.
Among the actions, are funding for microgrids in rural communities, a U.S. Department of Energy push for standardization of and increased access to energy data, and release of White House Council of Economic Advisers report on the “technical and economic considerations and opportunities” relating to the grid integration of renewables. On the private sector side, 16 developers and power companies set new storage procurement and deployment targets. Some are committing to smart water heaters, smart meters and demand response programs.
Federal programs to boost storage and microgrid capacity at federal installations and military bases may be a game changer, according to one electricity market analyst. In a research note on the commitments, reported PV Magazine, GTM Research highlighted storage deployment by the U.S. Navy for its “potential to genuinely grow the market beyond business-as-usual.”
Obama Says Climate Change a Threat to National Parks
“One of the things that binds us together is we only have one planet and climate change is probably the biggest threat—not only to natural wonders like this—but to the well-being of billions of people, coastal cities, agricultural communities that can be displaced in the span of a few decades by changes in temperatures that mean more drought, more wildfires,” Obama said during an interview with National Geographic that will air in later this summer to commemorate the National Park Service’s 100th anniversary. “Part of why it’s so important for us to raise awareness (about climate change) with the general public is: This is a solvable problem.”
He added: “Rising temperatures could mean no more glaciers at Glacier National Park. No more Joshua trees at Joshua Tree National Park.” Our changing climate, he said, could destroy vital ecosystems in the Everglades and threaten such landmarks as Ellis Island and the Statue of Liberty.
According to the National Parks Service, the park system’s many fragile ecosystems are “a testament to the reality of climate change.” They said glaciers could be completely gone from Glacier National Park by 2020, park facilities in Alaska are sinking due to thawing permafrost and archaeological sites are under threat from sea-level rise.
