A new 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 researchers unexpectedly found pollution's footprint in levels of an airborne byproduct of marine phytoplankton activity, which plummeted as soon as widespread fossil fuel usage began in the industrial era. The findings illustrate the long reach of fossil fuel emissions.
