Cutting carbon dioxide helps prevent drying
Date:3/24/2011

Washington, D.C.Recent climate modeling has shown that reducing the concentration of carbon dioxide in the atmosphere would give the Earth a wetter climate in the short term. New research from Carnegie Global Ecology scientists Long Cao and Ken Caldeira offers a novel explanation for why climates are wetter when atmospheric carbon dioxide (CO2) concentrations are decreasing. Their findings, published online today by Geophysical Research Letters, show that cutting carbon dioxide concentrations could help prevent droughts caused by global warming.

Cao and Caldeira's new work shows that this precipitation increase is due to the heat-trapping property of the greenhouse gas carbon dioxide in the atmosphere. Carbon dioxide traps heat in the middle of the atmosphere. This warm air higher in the atmosphere tends to prevent the rising air motions that create thunderstorms and rainfall.

As a result, an increase in the atmospheric concentration of carbon dioxide tends to suppress precipitation. Similarly, a decrease in the atmospheric concentration of carbon dioxide tends to increase precipitation.

The results of this study show that cutting the concentration of precipitation-suppressing carbon dioxide in the atmosphere would increase global precipitation. This is important because scientists are concerned that unchecked global warming could cause already dry areas to get drier. (Global warming may also cause wet areas to get wetter.) Cao and Caldeira's findings indicate that reducing atmospheric carbon dioxide could prevent droughts caused by climate change.

"This study shows that the climate is going to be drier on the way up and wetter on the way down," Caldeira said, adding:"Proposals to cool the earth using geo-engineering tools to reflect sunlight back to space would not cause a similar pulse of wetness."

The team's work shows that carbon dioxide rapidly affects the structure of the atmosphere, causing quick changes preci
