Drought drives decade-long decline in plant growth: study
Zhao and Running's analysis showed that since 2000, high- latitude Northern Hemisphere ecosystems have continued to benefit from warmer temperatures and a longer growing season. But that effect was offset by warming-associated drought that limited growth in the Southern Hemisphere, resulting in a one-percent net global loss of land productivity. The team published its findings on Friday in the journal Science.
