Deep and extended droughts are responsible for a recent slowdown in the amount of carbon dioxide that land plants pulled from the atmosphere as they grew, a new study suggests.

Satellite data suggest that between 1982 and 1999, the world’s net primary production — the amount of carbon pulled from the air as CO2 and stored in living plants each year — rose about 6 percent, says Maosheng Zhao, an ecologist at the University of Montana in Missoula.
