Fossil fuels — made up of ancient decomposing plants and animals deep in the earth — have been dug up at extraordinary rates. Scientists are now starting to pinpoint “details about rates and magnitudes and timing of changes” as well as the varying impact on regions, said Brown University climate scientist Kim Cobb.
