Climate change could cause more concentrated storms
Rising temperatures are causing heavy rain storms to become concentrated over smaller areas, a scenario that could cause extreme flooding in urban locations, according to a new study in Geophysical Research Letters.

Scientists search the seas for soot
Black carbon resides in the oceans for tens of thousands of years, yet it's not as abundant as expected, given the sheer quantity of it produced on land, according to a new study in Geophysical Research Letters.
