...starting in the 1950s strained already dry regions in western China. By 2004, 27% of the country's landmass suffered from some degree of desertification, according to the Chinese Meteorological Administration. China has invested heavily in planting trees and small shrubs over former croplands to prevent the spread of arid land eastward. The government has reported the rate of desertification has slowed after 2000, but says climate change and other environmental pressures means more than 186,000 square miles (300,000 sq km) of land are still at risk.

...world. "In northern areas," says Lobell, "you'll see an expansion of the growing season" - which, if the Finnish study is correct, won't necessarily help forests, but could be good for crops, since you can deliberately plant seeds that are suited to long summers. But in arid parts of the tropics, he says, where plant growth is limited by the availability of water, more frequent droughts could make things worse. "Large parts of the world," says Field, "are already at the warm edge of where things like to grow...
