How long?

One third of the planet will be desert by the year 2100, say climate experts in the most dire warning yet of the effects of global warming..

The century of drought, The Independent (U.K.), Oct. 4, 2006.

"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.."



This pic from the film "The Inconvenient truth" showing the global temp rise by 2100 shows that the carbon dioxide emissions come mainly from the "developed" countries whereas the resulting rise in temperature would be more in the poorer regions including Indian subcontinent, Africa and South America.
