The work by Mark Jacobson, director of Stanford University's Atmosphere / Energy program and a fellow at the university's Woods Institute, argues that cutting emissions of black carbon may be the fastest method to limit the ongoing loss of ice in the Arctic, which is warming twice as fast as the global average.
Credit: NASA / SVS Other recent studies have shown increasing losses of ice in parts of these sheets.
