Dartmouth study solves a marine mystery by tying ocean biomarker to pollution levels. A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long reach of fossil fuel emissions and provide support for the importance of clean-air rules, which the team found can reverse the effect. The impact of pollution on the Arctic began as soon as widespread fossil fuel usage took…
