Irrigation's cooling effects may mask warming in some regions -- for now

Expanded irrigation has made it possible to feed the world's growing billions -and it may also temporarily be counteracting the effects of climate change in some regions, say scientists in a new study. But some major groundwater aquifers, a source of irrigation water, are projected to dry up in coming decades from continuing overuse, and when they do, people may face the double whammy of food shortages and higher temperatures.
