President Donald Trump on Friday tasked Transportation Secretary Elaine Chao and U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt to negotiate fuel economy standards with California officials.
Their orders are to “work with the industry and with the state of California on developing a single national standard so that domestic automakers do not have to comply with two different regulatory regimes,” said Helen Ferre, a White House spokesperson.
It is not at all clear, however, that California is interested in finding a compromise. California has vowed to stick to its own, stricter standards authorized under the Clean Air Act despite plans by the Trump administration to push back on fuel economy and tailpipe emissions standards. On May 1, seventeen states and the District of Columbia filed a lawsuit in the D.C. Circuit Court of Appeals over the EPA’s revisiting Obama-era vehicle emissions and fuel economy standards last month.
The Friday announcement came as automakers met with Trump to discuss a draft proposal developed by the EPA and the National Highway Traffic Safety Administration that The Hill reports would freeze fuel efficiency requirements at 2020 levels for five years. It’s a proposal with which the Trump administration may move forward, according to Reuters.
Study Points to Possible Policies to Preserve Nuclear Plants
Early nuclear plant closures in the United States will mean the loss of zero-carbon electricity, but a new report from the Center for Climate and Energy Solutions (C2ES) suggests state and federal policy options that could preserve existing nuclear power generation. The report finds that when they retire, nuclear reactors, which supply more than half of the country’s zero-emissions power, are being replaced by more carbon-intensive natural gas.
The report points to some operational and technological developments that might put nuclear plants on a firmer footing. First, electrification of other sectors of the economy could increase energy demand, easing pressure on larger and older energy plants like nuclear reactors. Second, midday nuclear power, which may not be needed when solar is available, could be stored as hydrogen and then used as fuel or feedstock. And third, nuclear plants that are paired with renewables could ramp up and down, following demand.
With federal policy to drive nuclear development in the near term unlikely, the report concludes that any long-term decarbonization strategy for the United States would entail policy support for both advanced nuclear and renewables.
“The nut we really want to crack is how renewables and nuclear can work together for each other’s mutual benefit,” tweeted report author Doug Vine, a C2ES senior energy fellow. “We need to have 80% reductions by 2050. We’re not going to get there if renewables and nuclear are fighting each other.”
To preserve the emissions benefits of nuclear energy, the report includes in its policy solutions
state-level policies such as expansion of state electricity portfolio standards to allow nuclear and renewables to work together on a level playing field to one another’s benefit as well as zero-emission credits, already being implemented in some states, to support distressed facilities. Other solutions offered by the report are license renewals by the U.S. Nuclear Regulatory Commission that would allow reactors to operate for 80 years; a “meaningful” price on carbon implemented in power markets; and increased pursuit by government agencies, cities and businesses of power purchase agreements, which give both buyers and sellers some certainty over a specified time period, for nuclear power.
DOE Plan Lays out Steps to Protect Grid from Cyber Threats
A new U.S. Department of Energy plan lays out steps to do more to protect the country’s energy systems and diminish energy interruptions due to the increasing scale, frequency and sophistication of cyber attacks.
“Energy cybersecurity is a national priority that demands the next wave of advanced technologies to create more secure and resilient systems needed for America’s future prosperity, vitality, and energy independence,” said Secretary of Energy Rick Perry. “The need to strengthen efforts to protect our critical energy infrastructure is why I am standing up the Office of Cybersecurity, Energy Security, and Emergency Response (CESER). Through CESER and programs like CEDS, the Department can best pursue innovative cybersecurity solutions to the cyber threats facing our Nation.”
The five-year plan focuses on strengthening preparedness, coordinating responses, and developing the next generation of resilient energy systems in line with the creation of a cybersecurity office—announced earlier this year—to help carry out activities to protect the grid from attack.
The plan calls for research and development into equipment and technologies that would “make future systems and components cybersecurity-award and able to automatically prevent, detect, mitigate, and survive a cyber incident.”

The Regional Greenhouse Gas Initiative (RGGI), a nine-state carbon cap-and-trade program, continues to help lower emissions of carbon dioxide and benefit local economies, according to a new study by the Analysis Group. The study estimates that RGGI states gained $1.4 billion in net economic value from program during 2015–2017.
“I think this provides evidence of the fact that you can design a carbon-control program in ways that really are avoiding a drag on the economy and, in fact, actually helping to put more dollars in consumers’ pockets,” said Sue Tierney, a senior advisor with the Analysis Group and a member of the Nicholas Institute for Environmental Policy Solutions Board of Advisors.
RGGI, the first market-based regulatory program in the United States, is a cooperative effort implemented through separate authorities in Maryland, New York, Delaware, Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont to create a “cap” that sets limits on carbon dioxide emissions from the power sector—a cap lowered over time to reduce emissions. Power plants must purchase credits or “emissions allowances,” either from the regulators at auction or from other entities that can over comply, but the entire pool of such allowances is limited to the cap.
The study suggests that carbon dioxide emissions from power plants in the nine-state region have dropped by more than 50 percent since the program was launched in 2009. In the last three years, the program “has helped to lower the total amount of dollars member states send outside their region in the form of payments for fossil fuels by over $1 billion,” report authors write. “RGGI has lowered states’ total fossil-fired power production and their consumers’ use of natural gas and oil for heating.”
Brian Murray, a Nicholas Institute faculty affiliate and director of Duke University’s Energy Initiative, published a study in the journal Energy Economics in 2015 that had similar findings. It concluded that even when controlling for other factors—the natural gas boom, the recession, and environmental regulations—emissions would have been 24 percent higher in participating states without RGGI.
Nuclear Plants’ Economic Woes Could Threaten Clean Energy Growth
An analysis released by think tank Third Way explores the effect of three potential levels of premature nuclear plant closures (20 percent, 60 percent and 80 percent) on carbon emissions in the U.S. power sector. It finds that much of the shuttered generation will likely be replaced by natural gas, increasing emissions. Even if the lost capacity was entirely replaced by renewables, the analysis finds that the U.S. would still suffer a setback in its clean energy growth.
Failure to prevent early retirements of nuclear plants, it says, could unwind years of climate progress achieved by the U.S. power sector and jeopardize the Obama-era goal of reducing greenhouse gas emissions by 80 percent of 2005 levels by 2050.
Some 20 percent of U.S. electric power, and 60 percent of our zero-carbon electricity, comes from nuclear generation. Nearly half of U.S. nuclear plants are at or near the end of their 40-year licensed operating lives. These units have received 20-year license extensions, but starting around 2030 they will reach their 60-year limits. At this point, they must receive a second license extension or retire.
Nuclear power struggles to compete in an era of cheap natural gas and renewables. A few weeks ago, FirstEnergy announced that three nuclear plants will be prematurely deactivated by 2021. The utility asked for an order, under Section 202 of the Federal Power Act, to save them. On April 5, President Donald Trump said he would consider issuing just such an emergency order through the Department of Energy (DOE)—a move opposed by the American Petroleum Institute in a letter to the president, after the DOE opened an unofficial comment period on the matter last week.
If nuclear power is to be part of a U.S. climate change strategy over the next century, The Third Way argues that policymakers must address its increasingly precarious economics.
Their analysis concluded that more state-level policy efforts and expansion of zero-emissions credits programs could help curtail nuclear plant closures and incentivize growth in the clean energy source.
I recently wrote in The Conversation that extending federal tax credits to nuclear recognizes the societal benefits offered by that generation source and that without mechanisms for monetizing social benefits from carbon-free generation, new nuclear power plants are unlikely to be constructed. Such mechanisms could include a carbon tax to penalize high-carbon fuels and reward low-carbon and carbon-free sources and aggressive promotion of mature new nuclear reactor designs that could take up some demand currently met by retiring plants.
Emissions Standards Could Have Big Impact on California, Other States
Earlier this month, U.S. Environmental Protection Agency Administrator (EPA) Scott Pruitt, announced that greenhouse gas emissions standards for cars and light duty trucks should be revised. Although he did not indicate how far the rules should roll back, only that the EPA would begin drafting new standards for 2022–2025 with the National Highway Traffic Safety Administration, he did call out California, which is authorized under the Clean Air Act to set its own fuel standards. The move could spark a legal battle between the EPA and California about standards.
Privately, officials from the Trump administration and California, along with representatives of major automakers, may be searching for a compromise, The New York Times reports. Although a lawsuit is under consideration, Mary Nichols, the chair of the California Air Resources Board, said Tuesday she sees hope for a deal with the Trump administration over fuel economy and emissions standards.
“Reason could prevail,” Nichols said at Bloomberg New Energy Finance’s Future of Energy Summit in New York. “There’s a way to get to success, unless your goal is to roll over California and not allow us to have any standards.”
She told the Detroit Free Press that “if there are ways to eliminate things that aren’t contributing to overall environmental performance, we’re absolutely open to talking about them.”
For California, and the other states with transportation sectors that emit at least twice as much carbon as power plants—Massachusetts, New Jersey, New York and Washington––what happens with the vehicle emissions standards could affect states’ overall greenhouse gas emissions targets, reports ClimateWire.

Attorneys general of a dozen coastal states—North Carolina, California, Connecticut, Delaware, Maine, Massachusetts, Maryland, New Jersey, New York, Oregon, Rhode Island and Virginia—are expressing opposition to the Trump administration’s proposal to expand development of oil and gas in the Atlantic and Pacific oceans, calling it “outrageous” and “reckless.” In a letter, they called on U.S. Department of the Interior Secretary Ryan Zinke to cancel the proposal. They also expressed ire at the deal Zinke struck with Florida Gov. Rick Scott, which exempted his state from the drilling plan, pointing to the lack of analysis or clear process underlying the decision.
Two governors from opposing parties echoed that sentiment in a separate publication.
“We’ve seen this administration seemingly lift the concerns of one governor and one state above others,” wrote Maryland Gov. Lawrence Joseph Hogan Jr. and North Carolina Gov. Roy Cooper in an op-ed. “In removing Florida from the five-year plan, Zinke and the Trump administration have admitted that offshore drilling poses great risks to coastal economies.”
On Sunday Zinke reiterated why he exempted Florida—due to its unique currents and geology as well as the unanimous opposition of Florida’s legislature to the proposal.
“In the case of Florida, the governor asked first for an immediate meeting and every member on both sides of the aisle contacted my office, wrote letters on it. So Florida is unique,” Zinke said. “Not every state has all the members against it and the geology is different, the currents are different and so looking at it, we’re going to take the process, go through it, meet with every governor personally.”
In a meeting with Zinke the day before, Cooper said the Interior secretary was receptive to his requests for an extended proposal comment period and for three additional public hearings near North Carolina’s coast.
“He said that he was listening, and he heard each and every one of us,” Cooper said. “I think generally he was pretty positive about what we said. He didn’t make any promises to us.”
Cooper said he told Zinke that drilling could cause unrecoverable damage to the state’s $3 billion tourism and fishing industries.
“We told him there is no 100% safe method to drill for oil and gas off the coast, particularly in our area off of North Carolina that sees nor’easters, that sees hurricanes,” Cooper said. “It would be catastrophic if there were to be an oil spill.”
If North Carolina does not get an exemption like Florida, Cooper said he has no problem taking the federal government to court.
“Thousands of North Carolinians and 30 coastal communities have voiced their opposition to drilling off North Carolina’s shores,” said Josh Stein, North Carolina’s attorney general, in a statement. “I will do everything I can, including taking legal action, if necessary, to fight on behalf of our people, economy, and natural resources.”
Also seeking an exemption from the proposal—albeit a partial one—is Alaska Sen. Lisa Murkowski.
“There are certain areas that we feel are not opportune for leasing and for development,” said Murkowski, who chairs the Senate committee that oversees the Interior. “Let’s focus on where the opportunity is good and there is interest and defined resource with limited obstacles.”
As Another Plant Closes, Spotlight Is on Economics of Nuclear
New Jersey’s Oyster Creek nuclear power plant will shut down in October 2018, more than a year earlier than planned, Exelon Corp. announced last week.
Nuclear power is the nation’s largest source of carbon-free electricity, generating about 20 percent of U.S. electric power and 60 percent of our zero-carbon electricity. The challenge to maintain a zero-carbon nuclear fleet to meet climate goals—by keeping existing plants like Oyster Creek—often is economics. This challenge has been particularly apparent in competitive markets, where nuclear plants are not guaranteed cost recovery through ratepayers.
When Exelon CEO and President Chris Crane announced in 2010 that the plant would retire in December 2019, he said the plant faced “a unique set of economic conditions and changing environmental regulations that make ending operations in 2019 the best option for the company, employees and shareholders.” He said the plant’s decreasing value was due to the cumulative effect of negative economic factors, such as low market prices and demand, as well as the plant’s need for continuing large capital expenditures.
Meanwhile, new construction has been plagued with cost overruns. In December 2017, the Georgia Public Service Commission voted unanimously to allow construction of two new nuclear reactors at the Plant Vogtle site to proceed. Plagued by delays and escalating costs, the Vogtle reactors represented the only large-scale nuclear construction underway in the United States since abandonment of two reactors last summer by South Carolina Electric & Gas and Santee Cooper. The Georgia commission reaffirmed its decision this week, despite a challenge by consumer group Georgia Watch over concern about the ultimate cost to ratepayers.
EIA Projects United States Will Become a Net Energy Exporter in 2022
The U.S. Energy Information Administration (EIA) on Tuesday released its annual long-term energy outlook, which projects U.S. production of natural gas will increase through 2050. Production of crude oil and petroleum products, meanwhile, will decrease.
It projects that the United States will become a net energy exporter by 2022, four years sooner than the date projected in last year’s report, reversing “a near 70-year trend when the U.S. became a net energy importer in 1953,” said EIA Administrator Linda Capuano.
“The United States energy system continues to undergo an incredible transformation,” she added. “This is most obvious when one considers that the [report] shows the United States becoming a net exporter of energy during the projection period in the Reference case and in most of the sensitivity cases as well—a very different set of expectations than we imagined even five or ten years ago.”
Renewable generation more than doubles between 2017 and 2050, in EIA projections, with an average annual growth rate of 2.8 percent. EIA projections show 80 gigawatts of new wind and solar photovoltaic capacity being added between 2018 and 2021, spurred by declining capital costs and the availability of tax credits.
Energy consumption grows about 0.4 percent per year on average in the Reference case from 2017 to 2050, which is less than the rate of expected population growth (0.6 percent per year), according to the report.

A study published Monday in the journal Nature Climate Change suggests that more than a quarter of Earth’s land will become significantly drier even if the world manages to limit warming to the Paris Agreement goal of less than 2 degrees Celsius above pre-industrial levels. Limiting the temperature rise to the agreement’s more ambitious goal of 1.5 degrees Celsius could significantly reduce the amount of land affected.
“Our research predicts that aridification would emerge over about 20–30 percent of the world’s land surface by the time the global mean temperature change reaches 2 degrees C [Celsius],” said Manoj Joshi, study co-author from the University of East Anglia in the United Kingdom. “But two-thirds of the affected regions could avoid significant aridification if warming is limited to 1.5 degrees C.”
According to the study, the regions that would most benefit from keeping warming below 1.5 degrees Celsius are parts of South East Asia, Southern Europe, Southern Africa, Central America and Southern Australia.
The study authors used projections from 27 global climate models to identify the areas of the world where aridity will substantially change when compared to current year-to-year variations. With a temperature increase of 2 degrees Celsius, they found that between 24 percent and 32 percent of the Earth’s total land surface will become drier. At an increase of 1.5 degrees Celsius, only between eight percent and 10 percent of that surface becomes drier.
Aridification could dramatically increase the threat of widespread drought and wildfires. It is also a threat to agriculture, water quality and biodiversity, noted Chang-Eui Park, the study’s lead author from China’s Southern University for Sustainability and Technology.
Park likened the emergence of aridification to “a shift to continuous moderate drought conditions, on top of which future year-to-year variability can cause more severe drought. For instance, in such a scenario 15 percent of semi-arid regions would actually experience conditions similar to ‘arid’ climates today.”
Trump Administration Repeals Proposed Rules for Hydraulic Fracturing on Government Land
One day after a three-judge panel of the 10th U.S. Circuit Court of Appeals declined to reconsider it’s decision to overrule a lower court’s rejection of a proposed Obama-era rule regulating hydraulic fracturing on federal and Indian lands, the U.S. Department of the Interior’s Bureau of Land Management (BLM) rescinded the rule. Under the proposed rule, companies would have had to disclose the chemicals used in hydraulic fracturing, or fracking, whereby pressurized water is pumped underground to break open hydrocarbon deposits to increase well productivity.
The rule had been scheduled to go into effect in 2015, but it was never implemented due to court challenges by energy industry groups and several oil- and natural gas-producing states, which argued the rule was over-reaching and duplicative of state requirements, as well as by environmentalists, who pointed to a need to regulate potential risks to groundwater.
“This final rule is needed to prevent the unnecessarily burdensome and unjustified administrative requirements and compliance costs of the 2015 rule from encumbering oil and gas development on Federal and Indian lands,” BLM wrote in the 26-page final rule.
The move took effect immediately on December 29, skipping the 30-day waiting period often incorporated into rollbacks.
Vogtle Nuclear Project Gets Green Light
Georgia’s Public Service Commission has voted unanimously to allow construction of two nuclear reactors at Plant Vogtle to continue. Plagued by delays and escalating costs, the Vogtle reactors represent the only large-scale nuclear construction underway in the United States since abandonment of two reactors this summer by South Carolina Electric & Gas and Santee Cooper. This week, Dominion Power bought SCANA and assumed these failed South Carolina nuclear project costs.
“The decision to complete Vogtle 3 & 4 is important for Georgia’s energy future and the United States,” said Paul Bowers, chairman, president and CEO of Georgia Power, in a statement. “The Georgia Public Service Commission has shown leadership in making this complex and difficult decision and recognized that the Vogtle expansion is key to ensuring that our state has affordable and reliable energy today that will support economic growth now and for generations to come.”
Co-owned by Georgia Power, Oglethorpe Power, MEAG Power and Dalton Utilities, the reactors are presently scheduled to come online in 2021 (unit 3) and 2022 (unit 4).
The commission attached conditions to its approval of the Vogtle completion, including a lower return on equity for Georgia Power; more money returned to ratepayers; and the possibility of re-examining the project if Congress doesn’t extend a production tax credit for nuclear power past a 2021 expiration date.

Absent efforts well beyond those described in the Paris Agreement—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—climate change could pose a deadly threat to most humans by century’s end. This finding was suggested by an international group of climate science and policy experts in a pair of recently published studies.
To avoid the worst consequences of climate change, a paper published in the Proceedings of the National Academy of Sciences (PNAS) said the world would have to take aggressive measures to curtail the use of fossil fuels and emissions of short-lived climate pollutants such as methane. In addition, we would also have to extract carbon dioxide from the air and sequester it before it can be emitted.
According to the findings, which were originally published by the University of California’s Scripps Institution of Oceanography, there is a 5 percent chance of catastrophic change within roughly three decades, and a smaller chance that it would extinguish human life. It proposed two new classifications for climate change: “catastrophic,” meaning that adaptation would be difficult for most people, and “unknown,” or “existential,” meaning that adaptation would be impossible.
“There is a low probability that the change will be catastrophic,” said the study’s lead author, Veerabhadran Ramanathan, a professor of climate and atmospheric sciences at Scripps. “But you would not get on an airplane if you thought there was a 5 percent chance that it was going to crash.”
The researchers defined their proposed risk categories on the basis of guidelines established by the Intergovernmental Panel on Climate Change and previous independent studies. Even a global temperature increase limited to 1.5 degrees Celsius (2.7 degrees Farenheit)—the Paris Agreement’s aspirational goal—is categorized as “dangerous.” An increase greater than 3 degrees Celsius (5.4 degrees Farenheit) could be “catastrophic,” and an increase greater than 5 degrees Celsius (9 degrees Farenheit) could lead to “unknown” but potentially existential threats. For humans, catastrophic impacts include widespread famine and the exposure of more than 7 billion people to heat-related mortalities.
Policy and science experts, including Ramanathan, relied on the PNAS findings to compile a report on potential warming containment efforts. That report pointed to the need for greater weight on subnational government action and a sharp uptake in mature clean energy technologies—such as wind, solar, biogas, and geothermal—coupled with aggressive electrification of transportation and building energy use.
A separate analysis published in the journal Nature Geoscience says the Paris Agreement’s 1.5 Celsius aspirational goal may be more feasible than many think. It makes a fresh estimate of the necessary carbon budget, including updating measurements of the emissions and warming that have already occurred, and shows that the global carbon emissions budget that meets that goal is equivalent to 20 years of current global annual emissions. But other researchers have raised questions about the analysis—which, if correct, would have very large implications for climate policymaking. Aside from concerns about the new study’s methods and assumptions, broader questions about the definition of the carbon budget and how it should be calculated are now swirling.
Senators, Local Level Decision Makers Focus on Climate Action
After some speculation following comments by Secretary of State Rex Tillerson, the White House, on Monday, reaffirmed its commitment to withdraw from the Paris Agreement.
“There has been no change in the United States’ position on the Paris agreement,” White House Deputy Press Secretary Lindsay Walters told CNN. “As the President has made abundantly clear, the United States is withdrawing unless we can re-enter on terms that are more favorable to our country.”
Despite the White House’s stance on the global climate accord, others are taking steps to acknowledge and, in some cases, take specific action on the issue. Republican Sen. Lindsey Graham on Tuesday told guests attending a climate change conference convened at Yale University by former Secretary of State John Kerry that he supports a carbon tax to reduce greenhouse gas emissions.
“I’m a Republican. I believe that the greenhouse effect is real, that CO2 emissions generated by man is creating our greenhouse gas effect that traps heat, and the planet is warming,” said Graham. “A price on carbon—that’s the way to go in my view.”
Sen. Graham’s reinvocation of these concepts means that there may be some ability to have conversations again about the bipartisan solution to climate change (subscription).
State and local leaders associated with the C40 Cities Climate Leadership Group—a network of megacities dedicated to addressing climate change—remain focused on faster climate action. As part of a Climate Week convening, several mayors discussed how that action falls on them now that the United States is pulling out of the Paris Agreement.
“As mayors, our responsibilities also became even clearer. It’s not enough to reach our ‘80 by 50’ goal,” said New York City Mayor Bill de Blasio, referencing New York City’s earlier commitment to cut greenhouse gases by 80 percent by midcentury, “or to go along with the fantastic goal of keeping warming to two degrees Celsius. If the U.S. government is backing away, we had to step forward.”
On Wednesday, 91 U.S. cities and Denmark unveiled a climate plan that aims to enhance cooperation among companies, governments, regions and cities in an effort to promote green growth. The initiative is dubbed Partnering for Green Growth and the Global Goals 2030. Also, North Carolina joined 14 other states in the U.S. Climate Alliance—a bipartisan group of states committed to reducing their share of greenhouse gas emissions in line with the goals that countries agreed upon as part of the Paris Agreement.
“In the absence of leadership from Washington, North Carolina is proud to join the U.S. Climate Alliance, and we remain committed to reducing pollution and protecting our environment,” said North Carolina Gov. Roy Cooper. “So much of North Carolina’s economy relies on protecting our treasured natural resources, and I’m committed to maintaining the quality of their air we breathe for generations to come.”
Report: Energy Outlook to 2040
World energy consumption will increase 28 percent by 2040, the U.S. Energy Information Administration (EIA) projects in its latest International Energy Outlook 2017. Areas in China and Asia will consume the most energy—representing as much as 60 percent of increased demand.
The report indicates that fossil fuels will continue to dominate the world energy mix, making up 77 percent of energy use in 2040, while renewables, despite growing faster than any other fuel source during the coming years, will represent just 17 percent of world energy consumption by 2040. Demand for coal will remain relatively flat with consumption projected to decline from 27 to 25 percent between 2015 and 2040.
Global natural gas consumption is seen increasing by 1.4 percent per year over the forecast period.
“Abundant natural gas resources and rising production—including supplies of tight gas, shale gas, and coalbed methane—contribute to the strong competitive position of natural gas,” the report indicates.
Nuclear power is expected to grow the fastest behind renewables, with consumption increasing about 1.5 percent per year.

New research in the Bulletin of the American Meteorological Society finds that climate change influenced the majority of 16 extreme weather events in 2013. Specifically, it found evidence that climate change linked to human causes—particularly burning of fossil fuels—increased the odds of nine extreme events: amplifying temperature in China, Japan, Korea, Australia and Europe; intense rain in parts of the United States and India and severe droughts in New Zealand and California.
“It is not ever a single factor that is responsible for the extremes that we see; in many cases, there are multiple factors,” said Tom Karl, director of National Oceanic and Atmospheric Administration’s (NOAA’s) National Climatic Data Center, of the third NOAA-led annual report to make connections between human-caused climate change and individual extreme weather events.
Twenty groups of scientists conducted independent peer-reviewed studies on the same 16 extreme events occurring on four continents to arrive at their conclusions.
“There is great scientific value in having multiple studies analyze the same extreme event to determine the underlying factors that may have influenced it,” said Stephanie C. Herring of NOAA’s National Climatic Data Center and lead report editor. “Results from this report not only add to our body of knowledge about what drives extreme events, but what the odds are of these events happening again—and to what severity.”
Although the report concludes that the long durations of heat waves “are becoming increasingly likely” due to human-caused climate change, the effects of such change on other types of extremes—California’s drought and extreme rain in Colorado—are less clear.
“Temperature is much more continuous as opposed to precipitation, which is an on/off event,” said Karl. “If you have an on/off event, it makes the tools we have a little more difficult to use.”
Although the NOAA study reached mixed conclusions about the ongoing California drought’s connection to climate change, new research out of Stanford University is a bit more confident. The Stanford study found it is “very likely” that atmospheric conditions associated with the unprecedented drought in the state are linked to human-caused climate change.
“Our research finds that extreme atmospheric high pressure in this region—which is strongly linked to unusually low precipitation in California—is much more likely to occur today than prior to the human emission of greenhouse gases that began during the Industrial Revolution in the 1800s,” said Noah Diffenbaugh, a Stanford climate scientist.
According to the study, these high pressure ridges—currently parked over the Pacific Ocean—are now three times more likely to occur, and as long as high levels of greenhouse gases remain severe, drought will become more frequent.
Emissions from Industrial Facilities Rose Last Year
Reported greenhouse gas emissions from large industrial facilities were 0.6 percent—or roughly 20 million metric tons—higher in 2013 than in the year previous, according to new data from the U.S. Environmental Protection Agency (EPA), which linked the rise to greater coal use for power generation. A large majority of the increase, 13 million metric tons, was from the power sector alone—though overall emissions from power plants are down 9.8 percent since 2010. Reported emissions from the oil and natural gas sector declined 12 percent from 2011 levels, according to the report.
The news comes on the heels of an extension of the public comment period on EPA’s proposed Clean Power Plan, which aims to reduce greenhouse gas emissions from existing power plants, and of new comments by EPA Administrator Gina McCarthy concerning the proposal.
There will be “changes between proposal and final,” said McCarthy. “You may see adjustments in the state levels. You may see adjustments in the framework,” McCarthy noted, referring to the emissions reduction targets the EPA proposed for each state and to the formula used to calculate those targets. The changes could also include updates to the values for nuclear power and natural gas generation.
IEA Says Solar Could Become Dominate Energy Source by 2050
Solar could surpass fossil fuels as the largest source of electricity by mid-century, according to reports issued by the International Energy Agency (IEA). The reports suggests that together solar photovoltaic systems (PV) and concentrating solar power (CSP) could provide 27 percent of the world’s energy by 2050; fossil fuels would account for somewhere between 12 percent and 20 percent.
“The rapid cost decrease of photovoltaic modules and systems in the last few years has opened new perspectives for using solar energy as a major source of electricity in the coming years and decades,” said IEA Executive Director Maria van der Hoeven. “However, both technologies are very capital intensive: almost all expenditures are made upfront. Lowering the cost of capital is thus of primary importance for achieving the vision in these roadmaps.”
By 2050, the IEA said, PV will surge from today’s 150 gigawatts of installed capacity to 4,600 gigawatts, while CSP will increase from 4 gigawatts to 1,000 gigawatts (subscription). These projections are based on the IEA’s expectations that China and the United States will remain top installers for the foreseeable future and that PV will dominate up until 2030.

The Supreme Court, in a 6-2 ruling, upheld the U.S. Environmental Protection Agency’s rule to regulate pollution from coal-fired power plants that drifts across state lines.
The Cross State Air Pollution Rule (CASPR), which applies to 28 states, aims to reduce emissions of sulfur dioxide and nitrogen oxides, which can lead to soot and smog. The rule was invalidated by a federal appellate court in August 2012 after it was challenged by a group of upwind states and industry because it enforced pollution controls primarily on coal plants. The higher court found the EPA acted reasonably.
“Most upwind states propel pollutants to more than one downwind state, many downwind states receive pollution from multiple upwind states, and some states qualify as both upwind and downwind,” wrote Justice Ruth Bader Ginsburg. “The overlapping and interwoven linkages between upwind and downwind states with which EPA had to contend number in the thousands.”
The Clean Air Act, and specifically the good neighbor provision at issue, she said, does not tell the EPA what factors to consider. “Under Chevron [v. Natural Resources Defense Council] we read Congress’ silence as a delegation of authority to EPA to select among reasonable options,” she added (subscription).
The rule does not address greenhouse gas emissions, which are the subject of another proposed rule for existing coal-fired power plants that is expected to be released in June. Also due next month is another Supreme Court decision, this one on whether the EPA’s regulation of stationary source emissions through permitting requirements under the Clean Air Act was “a sensible accommodation or an impermissible exercise of executive authority.”
Electricity Sector Uncertainty and GHG Emissions
Data from the Energy Information Administration (EIA) suggests that accelerated plant retirements in either the nuclear power or coal power generation industry would change projections of carbon dioxide emissions. Accelerated retirements of nuclear plants would boost emissions; accelerated retirements of coal-fired plants would reduce them.
EIA predicts U.S. emissions could be 4 percent higher than expected by 2040, but 20 percent lower if more coal plants retire. Lower natural gas prices and stagnant growth in electricity demand will lead to the loss of 10,800 megawatts of U.S. nuclear generation—roughly 10 percent of total capacity by the end of the decade.
Even with the uncertainty facing the electricity sector, there are multi-benefit approaches that state-level environmental regulators and utility commissioners can use to reduce carbon dioxide emissions while simultaneously addressing other electricity sector challenges. That’s according to a new study by the Nicholas Institute for Environmental Policy Solutions at Duke University. The study examines Clean Air Act section 111(d) compliance strategies offering these multi-benefit approaches.
Studies Focus on Sea Level Rise, Land Subsidence
Oyster reefs are creating resilience in the face of sea level rise and extreme weather. A new study in the journal Nature Climate Change suggests that vertical oyster reef accretion could outpace climate change-induced sea level rise, helping rebuild a shrinking oyster population. The research is the first to suggest that the reefs would act differently than any normal sea wall.
The study of 11 oyster reefs in intertidal areas on the North Carolina coast from 1997 to 2011 found that intertidal reefs have the potential to grow 11 centimeters vertically a year. Researchers acknowledged that much remains to be studied, including subtidal reefs.
Sea level rise may not be the only problem for some regions. In coastal megacities, the extraction of groundwater for drinking water is causing land to sink 10 times faster than sea level rise, according to another new study.
“Land subsidence and sea level rise are both happening, and they are both contributing to the same problem—larger and longer floods, and bigger inundation depth of floods,” said Gilles Erkens, who led the study by the Netherland’s Deltares Research Institute. “The most rigorous solution and the best one is to stop pumping groundwater for drinking water, but then of course you need a new source of drinking water for these cities. But Tokyo did that and subsidence more or less stopped, and in Venice, too, they have done that.”
Financial loss due to sinking, the research said, would reach nearly a billion dollars yearly and cities such as Jakarta, Bangkok and Ho Chi Minh City will sink below sea level if action isn’t taken.
Could Climate Change have Played Role in the Mount Everest Disaster?
Some scientists are linking the Mount Everest ice release—known as a serac—that killed 16 people last month to climate change.
“You could say [that] climate change closed Mount Everest this year,” said Western Kentucky University Professor John All (subscription).
Research conducted by the Kathmandu-based International Center for Integrated Mountain Development showed that the Himalayan glaciers shrunk 21 percent in roughly 30 years. Studies by the Chinese Academy of Sciences, which point to data collected through on-site monitoring and remote sensing, show a 10 percent reduction in ice during the last four decades.
Still, others say it is impossible to link any one disaster to long-term changes. Much of the evidence that warming is occurring is anecdotal, and the number of scientific observations is not large enough to draw solid conclusions, NBC News reports.
