The National Oceanic and Atmospheric Administration (NOAA) announced last week that carbon dioxide concentrations at the Mauna Loa Observatory in Hawaii surpassed the milestone 400 parts per million for a sustained period. NOAA has since revised the figure—on the basis of computer analysis—saying its May 9 readings actually remained fractions of a point below the historic level, coming in at…
Carbon dioxide emissions are soaking into Arctic waters and affecting the chemistry of the ocean, a new report by the Arctic Monitoring and Assessment Program shows. Increasing carbon dioxide emissions and freshwater runoff challenge the ocean’s ability to neutralize acidification—an imbalance caused by absorption of the greenhouse gas from the air. The study said the Arctic’s cold water makes it more vulnerable to…
According to a new U.S. Geological Survey (USGS) assessment, two formations in the central United States hold three times the amount of natural gas and two times the amount of oil than the federal government previously estimated. Concentrated in the Dakotas and Montana, the Bakken and Three Forks formations are expected to hold 7.4 billion barrels of recoverable oil and…
The European Union Parliament rejected a proposal to backload the auctioning of credits within its Emissions Trading Scheme this week. The proposed “backloading” plan would have removed a surplus of emissions permits from the world’s largest carbon market—potentially saving it from collapse and making fossil fuels more expensive for utilities and factories to burn. The surplus, partly a result of the…
Senate confirmation hearings for Ernest Moniz and Gina McCarthy—President Barack Obama’s appointees to oversee the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA)—began this week. For Moniz, the Massachusetts Institute of Technology physicist, committee grilling started Tuesday. Natural gas exports were a popular topic throughout Moniz’s hearing—signaling his likely support for exports as a way to combat climate change. With…
The U.S. Environmental Protection Agency (EPA) on Friday announced its proposed Tier 3 rules, which would reduce allowable amounts of sulfur in gasoline and help automobiles’ catalytic converters capture more pollutants. The new measures would reduce sulfur in gasoline by more than 60 percent—from the present average of 30 parts per million to 10 parts per million by 2017—an environmental benefit comparable to taking 33 million…
A new study in the journal Proceedings of the National Academy of Sciences (PNAS) finds global temperatures to be one of the best predictors of hurricane activity. In fact, the PNAS study found that a one degree Celsius (1.8 degrees Fahrenheit) rise in global temperatures could multiply the frequency of Katrina-like storms by two to seven times. In the Arctic, melting sea ice—which reached its sixth lowest…
Since China announced it will hold off plans to introduce a carbon tax, the idea has generated some activity on Capitol Hill. Lawmakers on Tuesday proposed a draft bill that would charge the largest industrial polluters a fee for, or carbon tax on, their fossil-fuel emissions. The plan, proposed by Rep. Henry Waxman (D-Calif.), Sen. Sheldon Whitehouse (D-R.I.), Rep. Earl…
A new study published in the journal Proceedings of the National Academy of Sciences indicates that even as high as 30,000 feet in the sky, fungi and bacteria are present in the air. These living microorganisms could very well affect global climate. “The million-dollar question in the field [right now] is how much living things can impact clouds, the hydrological cycle and…
Just days after the announcement that last year was the warmest in history for the continental United States, the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) found global temperatures are rising too. In their separate annual analyses of surface temperatures, NASA and NOAA ranked 2012 among the 10 warmest years on record globally (NOAA showed 2012…
It’s official. Last year was the warmest year in history for the contiguous United States with at least 356 record high temperatures tied or broken, according to the National Oceanic and Atmospheric Administration (NOAA). Average temperatures in 2012 were above the 20th century average by more than 3 degrees Fahrenheit. Temperatures also beat a previous record set in 1998 by a full degree,…
As lawmakers in Washington, D.C., debate the so-called fiscal cliff—when U.S. federal tax increases and spending cuts are due to take effect at the end of 2012—new research in the journal Nature Climate Change says we are already at the edge of a climate cliff. It explores the cost and risk associated with surpassing critical emissions thresholds by 2020, and what would need to…
A collection of papers now out in the journal Proceedings of the National Academy of Sciences (PNAS) looks at the response to the Deepwater Horizon Oil Spill in 2010, examining whether it was successful and how it could be improved. The release of the reports comes just days after the U.S. Environmental Protection Agency (EPA) suspended BP from obtaining new U.S. contracts due to…
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.…
