A new study from the journal Nature Geoscience has found that 50% of the total temperature increases in the Arctic over the last century have been due to black carbon, a substance that only stays in the atmosphere for several days to weeks.

This means that if black carbon emissions were immediately halted, it may only take a few weeks for warming trends to reverse by half.

A new study shows that pollution from automobiles and coal-fired power plants is contributing to the melting of mountain snowpacks up to a month early, thereby exacerbating water shortages and other problems across the arid western United States.
