Grasslands wetter

Grassland ecosystems could become wetter as a result of global warming, according to a new study by researchers from Stanford University and the Carnegie Institution of Washington. This surprising result, published in the Proceedings of the National Academy of Sciences (PNAS), contradicts numerous climate models predicting that higher temperatures could dry out natural landscapes, including grasslands.

“We found that, once the plants shut down, the moisture is effectively trapped in the soil,” noted co-author Christopher B. Field, a professor by courtesy of biological sciences at Stanford and director of the Carnegie Institution’s Stanford-based Department of Global Ecology.
