Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.

If current rates of decline continue through 2020, the state will need to reduce emissions at a rate of 4.97% each year in the decade between 2020 and 2030, and produce even steeper declines in the period from 2030 to 2050, if it is to meet current climate goals. But the effects of these efforts seem to be reaching a plateau.
