The concentration and the rate of carbon dioxide (CO2) levels in the atmosphere are spiking, according to new analysis from the World Meteorological Organization (WMO). Scientists believe the record levels are not only the result of emissions but also of plants and oceans’ inability to absorb the excess amounts of CO2.
“We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels,” said WMO Secretary-General Michel Jarraud. “Carbon dioxide remains in the atmosphere for many hundreds of years and in the ocean for even longer. Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification.”
The WMO study found that CO2 concentrations increased more during 2012 and 2013 than during any other year since 1984—and significantly higher than they were before the Industrial Revolution (278 parts per million in 1750 compared with 396 parts per million in 2013). Other greenhouse gases are also on the rise—methane has risen by 253 percent since the Industrial Revolution, and nitrous oxide has risen to 121 percent of pre-industrial levels.
A report by PricewaterhouseCoopers (PwC) on how countries grow their economy while reducing their greenhouse gas emissions linked to energy concluded that the gap is widening between what the world is achieving and what it needs to do in terms of limiting global temperatures to 3.6 degrees Fahrenheit above preindustrial levels—the target agreed at the United Nations 2009 climate summit. Carbon intensity was reduced, on average, 1.2 percent from 2012 to 2013. The needed annual reduction is 6.2 percent.
The PwC report also found that places like China, Brazil, Russia, Indonesia, Mexico and Turkey are reducing their carbon intensity far better than the world’s rich nations.
“What we found this year is that emerging economies have outperformed the G7 countries because their economies are growing much more rapidly than their emissions,” said Jonathan Grant, PwC director of sustainability and climate change.
BP Gets U.K. Support in Court Filing
The British government, in a court filing, offered support to limit payments by BP to victims of the 2010 Deepwater Horizon oil spill, arguing that court-mandated compensation by a U.S. District Court in 2012 undermined confidence in judicial fairness. BP has spent much of this year working to convince federal courts in New Orleans that the settlement deal allowed millions in payments to go to what it says are undeserving businesses.
In its Sept. 4 filing, the British government said the prospect of payments going to people unaffected by the spill raises “grave international comity concerns.”
“The lower courts’ rulings have dramatically expanded [BP’s] scope of liability far beyond anything that would seem to be appropriate under our shared common-law traditions or that anyone would reasonably expect,” the British government wrote in an Amicus Curiae.
The brief comes on the heels of another more recent court ruling that found the company “grossly negligent” in the explosion that killed 11 men and allowed millions of barrels of oil to flow out of the Macondo oil well into the Gulf of Mexico. The ruling opened the door to new civil penalties that could amount to as much as $18 billion and that could pressure the company to sell assets from the Americas to Asia and Russia.
Regulating Emissions from the Airline Industry
As it did to implement a tailpipe rule that sets greenhouse gas emissions standards for cars and light trucks, the U.S. Environmental Protection Agency (EPA) could use an endangerment finding to regulate emissions from the airline industry.
The EPA announced plans to release an endangerment finding proposal in April 2015 that looks at whether emissions from airlines endanger public health or welfare.
“If a positive endangerment and cause or contribute findings are made, U.S./EPA is obligated under the Clean Air Act to set [greenhouse gas] emission standards for aircrafts,” the EPA said. A process to finalize such a finding could take up to year.
The announcement comes as the electricity industry faces proposed regulations that would cut carbon dioxide emissions 30 percent below 2005 levels, a move that governors of 15 states recently wrote “exceeds the scope of federal law” in a letter to President Obama.

A federal appeals court upheld the U.S. Environmental Protection Agency’s Mercury and Air Toxics Standards (MATS) requiring power plants install technology to cut emissions of mercury and other air pollutants. MATS was challenged by industry and several states that argued the EPA should have considered costs when determining whether it was “appropriate and necessary” to go forward with the standards. The EPA contended the rule was required under the Clean Air Act.
“On its face,” the majority opinion said, the Clean Air Act “neither requires EPA to consider costs nor prohibits EPA from doing so. Indeed, the word ‘costs’ appears nowhere” in that section of the law.
Although Judge Brett Kavanaugh—one member of the three-judge panel—agreed with the majority in other aspects of the ruling, he wrote a dissenting opinion on when the EPA should have considered the costs of MATS.
“The estimated cost of compliance with EPA’s Final Rule is approximately $9.6 billion per year, by EPA’s own calculation … To put it in perspective, that amount would pay the annual health insurance premiums of about two million Americans. It would pay the annual salaries of about 200,000 members of the U.S. Military. It would cover the annual budget of the entire National Park Service three times over,” Kavanaugh wrote.
Most power plants will have until March 2015 to meet the requirements set forth by the standards, but extensions to 2016 are possible. Despite the litigation, nearly 70 percent of coal-fired power plants are already in compliance with MATS, according to the Energy Information Administration.
The appeals court ruling comes as the EPA released findings that between 2011 and 2012 U.S. greenhouse gas emissions dropped 3.4 percent—an overall decrease of 10 percent below 2005 levels. The findings are based on data in the agency’s annual inventory of U.S. greenhouse gas emissions and sinks. The agency attributed the decrease, in part, to reduced emissions from electricity generation, much of which is attributable to the increased usage of gas instead of coal—a change that has been influenced by the mercury regulations.
Methane Emissions Rule May be on Horizon
Five papers exploring methane emissions from compressors, leaks, liquid unloading, pneumatic devices and hydraulic fracturing production were released by the EPA for public comment Tuesday.
“The white papers will help EPA solidify our understanding of certain sources of methane and volatile organic compound (VOC) emissions in the oil and natural gas industry,” the agency said in a statement. “Methane is a potent greenhouse gas, and VOCs contribute to the formation of harmful ground-level ozone (smog).”
The release of the papers is a first step in what could become a new set of regulations governing emissions of methane from oil and gas operations.
A day earlier, a study published in the Proceedings of the National Academy of Sciences suggested that the EPA underestimated methane emissions from oil and gas operations. In a survey of hydraulic fracturing sites in southwestern Pennsylvania, the peer-reviewed study found that drilling operations released methane at rates that were 100 to 1,000 times greater than the EPA expected. Seven well pads—1 percent of all the wells in the research area—accounted for 4 to 30 percent of the recorded emissions.
Four Years Later, BP “Active” Spill Response Concludes
The “active cleanup” phase of BP’s Deepwater Horizon oil spill ended this week, days before the four-year anniversary of the 2010 spill.
“Let me be absolutely clear: This response is not over—not by a long shot,” said Capt. Thomas Sparks, the Coast Guard federal on-scene coordinator for the Deepwater Horizon response. “Our response posture has evolved to target re-oiling events on coastline segments that were previously cleaned.”
BP said its cleanup involved aerial patrols over more than 14,000 miles of shoreline and ground surveys covering more than 4,400 miles.
“Immediately following the Deepwater Horizon accident, BP committed to cleaning the shoreline and supporting the Gulf’s economic and environmental recovery,” BP said in a press release. “Completing active cleanup is further indication that we are keeping that commitment.”
Multiple studies are attempting to assess not only the reach of the spill, but also its health effects for spill responders and Gulf wildlife. A new report by the National Wildlife Federation used data from independent scientists and the National Oceanic and Atmospheric Administration to assess how 14 species were faring. Some—such as the bottlenose dolphins and sea turtles—are still dying in large numbers due to the spill.

New analysis from the World Health Organization (WHO) links exposure to air pollution to roughly 7 million deaths annually. The report confirms that air pollution is now the world’s largest environmental health risk. It estimates 4.3 million people died in 2012—mainly due to cooking inside with coal or wood stoves. Another 3.7 million died from outdoor pollution, including diesel engine and factory emissions. The figures—more than double previous estimates—indicate that air pollution kills more people than smoking, diabetes and road deaths combined.
“The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes,” said Maria Neira, director of WHO’s Department for Public Health, Environmental and Social Determinants of Health. “Few risks have a greater impact on global health today than air pollution; the evidence signals the need for concerted action to clean up the air we all breathe.”
The Western-Pacific region—including China, Japan and Australia—represented 41 percent (2.88 million) of the global deaths due to air pollution in 2012. In that year, countries in this region combined with countries in southeast Asia accounted for 5.8 million air pollution-related deaths.
Only three of 74 Chinese cities fully complied with state pollution standards in 2013. Earlier this month, Chinese Premier Li Keqiang classified air pollution as a top priority for the nation’s authorities. China is now using drones to spy on industries in Beijing and other cities where illegal polluting may be contributing to the nation’s smog problem. These unmanned crafts take photographs of smokestack scrubbers and assess smoke color in the images for pollution.
“You can easily tell from the color of the smoke—black, purple, brown—that the pollution is over the limit, because if smokestack scrubbers are operating properly, only white smoke is emitted,” said ministry official Yang Yipeng.
In new tests led by the China Meteorological Administration, drones could be used during peak air pollution periods to spray chemicals that freeze pollutants, allowing them to fall to the ground.
Texas Disaster Puts Oil Spills in Spotlight
As news headlines commemorated the 25th anniversary of the Exxon Valdez disaster, in which more than 10 million gallons of crude oil were spilled in the waters off Alaska, emergency crews were dealing with a new disaster in one of the country’s busiest shipping channels: the Houston Ship Channel.
Though millions of gallons smaller than the Exxon Valdez spill or the BP’s Deep Horizon spill in 2010, the spill from a barge collision near Galveston closed the shipping lane for several days while a high-tech buoy system helped guide the cleanup.
Since the Exxon Valdez, the United States has experienced at least two-dozen major oil spills, ranging from a few hundred to millions of gallons. Scientists are still discovering the ecological costs associated with these spills.
A new study published in the journal Proceedings of the National Academy of Sciences finds grim implications for the hearts of fish that were embryos, larvae or juveniles at the time of the BP oil spill, which coincided with tuna-spawning season. Led by the National Oceanic and Atmospheric Administration (NOAA), the study links the spill to potentially lethal heart defects in species of tuna, amberjack and other predatory fish.
“Larvae exposed to high levels were dead within a week,” said study leader John Incardona. “But we still don’t know how long they lived after exposure to lower levels [of crude oil], or how much spawning area may have been impacted.”
The NOAA study follows research out in February suggesting that low concentrations of crude can disrupt the signaling pathways responsible for regular heart rhythms in fish.
Renewable Energy Makes Strides
Cheap installation costs, high electricity prices and government subsidies have allowed the cost of solar power to stay on par with the cost of traditional energy sources—at least in Germany, Spain and Italy. That’s according to a new report by the consulting firm Eclareon. “Soft costs” and demand are keeping the same from ringing true in the United States, according to The Week.
A new experimental house—developed by the University of California, Davis, and Honda—is designed to generate more electricity than it consumes and to store the extra energy in a car’s battery for later use.
“It’s a new world in terms of vehicles operating not as isolated artifacts but as being part of a larger energy system, and I think the greatest opportunity for automakers is figuring out how their vehicles become part of that system,” said Daniel Sperling, director of the Institute for Transportation Studies at the University of California, Davis.
The home uses a geothermal system to provide heating and cooling. Solar panels, energy-efficient automated lighting, electric vehicle charging and pozzolan-infused and post-tensioned concrete use less than half of the energy of a similarly sized new home in the Davis area.

Thousands have converged for a two-week meeting in the Qatari capital of Doha for the 18th Conference of the Parties (COP 18) to the United Nations Framework Convention on Climate Change (UNFCCC). Running through Dec. 7, the U.N. conference brings together environmental minds across the world to work toward a legally binding agreement on climate change. At stake: the Kyoto Protocol. Last week, the World Bank issued a report suggesting that a temperature rise of more than 4 degrees Celsius (7.2 degrees Fahrenheit) by 2100 could cause widespread crop failures, malnutrition and significant sea-level rise. Kyoto is the only global agreement to cut greenhouse emissions, and it is set to expire at the end of this year. In The Washington Post, Brad Plumer shows what Kyoto has (and has not) achieved, and what any new agreement must achieve in order to avoid 3 or 4 degrees Celsius of warming.
The world is watching to see whether details for a second phase of the Kyoto Protocol, which lays the groundwork for a new global treaty, can be agreed upon. A second phase of Kyoto, Nature reports, would only temporarily replace the original agreement. That’s why some hope COP 18 climate negotiators commit to signing a new treaty by 2015, to take effect by 2020—or possibly earlier if some countries pushing for more ambitious action get their way.
Counterparts from European and vulnerable nation delegations routinely criticize the U.S. as the major reason these negotiations lack ambition. Experts say China and the United States aren’t keeping pace with the smaller countries—the global leaders in generating power from clean sources. Still, some are cautiously optimistic the U.S. will be more than a bystander during talks in light of the recent destruction caused by Hurricane Sandy.
Studies Coming out of Doha
A number of new studies informing decisions during COP 18 are being shared at the conference by organizations across the world. Among the highlights:
Permafrost: The United Nations Environment Program released a report recommending that the Intergovernmental Panel on Climate Change (IPCC) address the gases emitted from melting permafrost, which could account for almost 40 percent of the world’s greenhouse gas emissions.
Climate Change: A report by the World Meteorological Organization stated concentrations of greenhouse gases in the Earth’s atmosphere reached record highs in 2011, indicating “climate change is taking place before our eyes.”
Blue Carbon: Destruction of coastal habitats may release as much as 1 billion tons of carbon dioxide into the atmosphere each year, 10 times higher than previously reported. A new report by Duke University’s Nicholas Institute for Environmental Policy Solutions looks at how this blue carbon—stored in sediment layers below mangroves sea grasses and salt marshes—might be addressed within existing UNFCCC mechanisms.
Sea-Level Rise: Another report says sea levels are rising 60 percent faster than the United Nations originally predicted.
Criminal Charges Bar BP from New Contracts
BP appeared in court this week to answer to charges brought over the 2010 Gulf of Mexico oil spill. At a brief arraignment hearing before a federal judge in New Orleans, BP’s lawyer said the company’s board authorized entering a not guilty plea as a procedural matter, but the company still intends to plead guilty later.
On Nov. 15, the company announced that it would plead guilty to manslaughter, obstruction of Congress and other charges and agreed to pay a record $4.5 billion in penalties to resolve a federal probe of the Deepwater Horizon disaster, which killed 11. As a result of those criminal charges, the company and its affiliates were recently suspended from new contracts with the U.S. government for a “lack of business integrity.” The temporary suspension won’t affect current contracts, but it was unclear what new or pending contracts were affected. “Federal executive branch agencies take these actions to ensure the integrity of federal programs by conducting business only with responsible individuals or companies. Suspensions are a standard practice when a responsibility question is raised by action in a criminal case,” the U.S. Environmental Protection Agency said in a statement.

The U.S. Energy Department announced plans to spend more than $5 million researching the potential to produce natural gas from deep-sea methane hydrates—ice-like formations that contain natural gas and are stable at depths of more than 300 feet. The Energy Department calls them “the world’s largest untapped fossil energy resource”—some estimate they are twice as abundant as all remaining natural gas and petroleum reserves. According to William Dillon of the U.S. Geological Survey, “The worldwide amounts of carbon bound in gas hydrates is conservatively estimated to total twice the amount of carbon to be found in all known fossil fuels on Earth.” This is the same methane hydrate that could be released into the atmosphere if Antarctica’s ice sheets thin as a result of climate change.
Another abundant resource sharing headlines is wind: there may be enough wind on Earth to meet global power demands (subscription), at least technically, according to a new report. Wind power to such a degree would require covering much of the Earth’s surface and oceans with turbines. Though wind power currently supplies about 4.1 percent of U.S. electric power, the study concludes that we could produce about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.
Challenges of Climate Change
In the U.S., drought and rising temperatures are posing challenges for power plants. The Washington Post details the burdens these factors are placing on coal-fired, nuclear and hydroelectric power generators—including the Hoover Dam, where low water levels make meeting demand difficult. The news has Henry Waxman and Bobby Rush calling for a probe into whether climate change could threaten the nation’s electricity supply. In their letter, the two cite several cases in which power plants were forced to cease operation or cut back output when nearby water sources became too warm to cool the plants.
Despite suffering the worst drought in 50 years, farmers will collect far more corn crop than previously predicted. Still, at 10.727 billion barrels and the U.S. Department of Agriculture predicts prices will remain at $7 per bushel. The corn yield is still projected to be the worst since 1995.
While climate conditions are impacting farmers, more and more big businesses are seeing the potential impact to their operations. A new report indicates approximately 81 percent of the largest global companies that report sustainability strategies and greenhouse gas emissions include disruptions from climate change among corporate risk disclosures. Thirty-seven percent of those companies consider droughts, fires and the like a serious threat.
Arctic Drilling Sees More Delays
Drifting ice halted Shell’s efforts to drill its first well in the Arctic’s Chukchi Sea just one day into the already-delayed project. The arrival of the ice is the latest in a series of regulatory and equipment setbacks for the company, which has already spent about $4 billion on the effort. Though the federal government estimates the Alaska Arctic offshore region contains close to 26 billion barrels of recoverable oil, sea ice and harsh conditions make for a short drilling season. The moving ice may bring them closer to the Sept. 24 close of the drilling season—stated in the terms of their permit—with little progress toward their goal. “Depending on conditions, it could be a few or, potentially, several days before it’s safe enough to resume drilling,” said Shell spokesman Curtis Smith.
Shell has petitioned for an extension of the season because its projections had shown the arrival of ice much later in the season. The area’s unforgiving conditions have led some doubt how safely these efforts could be carried out—despite extra efforts to beef up the same equipment that failed in the BP Deepwater Horizon spill in the Gulf of Mexico. Even so, the U.S. Coast Guard’s Paul F. Zukunft, who served as the federal coordinator on the 2010 BP spill, said, “I would never be confident [we could handle a major spill]. You’ll never get all the oil.”
In Louisiana, that’s been the case. Nearly two years after the BP spill Hurricane Isaac has churned up tar balls positively identified as originating from the 2010 event. BP has proposed a “deep clean” of these beaches—sifting as deep as 4 feet—to remove contaminants before sand deposited by new storms covers over the tarballs. Researchers at Louisiana State University are looking at other methods—more specifically, blooms of bacterial biomass and whether they could consume oil and gas from the BP spill trapped about a half-mile below the water’s surface. Tests so far say yes—showing these microbes have consumed about 200,000 tons of this oil.
