Tens of thousands of pounds of methane leak per hour from equipment in three major natural gas basins that span Texas, Louisiana, Arkansas and Pennsylvania, according to airborne measurements published today by a NOAA-led team of scientists. But the overall leak rate from those basins is only about one percent of gas production there—lower than leak rates measured in other gas fields, and in line with federal estimates.
There is no substitute for dramatic reductions in greenhouse gas emissions to mitigate the negative consequences of climate change, a National Research Council committee including CIRES director Waleed Abdalati concluded in a two-volume evaluation of proposed climate-intervention ("geoengineering") techniques.
Sea-level rise may not be not eating away at Colorado’s borders, but climate change exposes other critical vulnerabilities in the state, according to a new report. Rising temperatures will likely take a toll on cattle and crops, for example, and could more often leave junior water rights holders with little water and few options.
We tend to think of summer as prime time for pollution—picture the haze that hangs over big cities on hot, steamy days. That's when increased sunlight and temperatures speed up chemical reactions that transform pollutants in the air into other "secondary" pollutants, including ozone, particulate matter, and others. But pollution doesn't cease at summer's end. Instead, the pathways to these familiar summertime pollutants are altered in ways that haven't been well studied and that therefore aren't well understood.
Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at the world’s northern reaches, according to a new paper.
To accurately forecast wintertime bad air days in Utah’s Uintah Basin, researchers must use real atmospheric measurements to estimate chemical emissions from nearby oil and natural gas fields, a new study in Atmospheric Chemistry and Physics has found.
San Francisco, California —A combination of new tools and old photographs are giving scientists a better view of Greenland’s ice, and recent discoveries promise to improve forecasts of the region’s future in a warmer world. Overall, the findings show Greenland's ice is vulnerable to periods of rapid change including vicious cycles of warming promoting further warming.
A measles vaccine made of fine dry powder and delivered with a puff of air triggered no adverse side effects in early human testing and it is likely effective, according to a paper to be published November 28 in the journal Vaccine. The paper is now available online.
