A third of land desert by 2100

One third of the planet will be desert by the year 2100, say climate experts

Michael McCarthy, The Independent:

Drought threatening the lives of millions will spread across half the land surface of the Earth in the coming century because of global warming, according to new predictions from Britain's leading climate scientists.

Extreme drought, in which agriculture is in effect impossible, will affect about a third of the planet, according to the study from the Met Office's Hadley Centre for Climate Prediction and Research.

It is one of the most dire forecasts so far of the potential effects of rising temperatures around the world - yet it may be an underestimation, the scientists involved said yesterday.
