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.

Erratic as normal - Arctic sea ice loss expected to be bumpy in the short term

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. Read More ...

Forecasting and explaining bad air days in Utah’s oil and gas fields

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. Read More ...
