A key type of intermediate in atmospheric chemistry reacts faster to form compounds that produce cooling aerosols than previously realized, according to a report in Science (DOI: 10.1126/­science.1213229). The experimental results indicate that the role of green plants—emissions from which help form the intermediates—in combating global warming may be larger than currently understood.

Plants emit alkenes, such as isoprene and . . .
