Global Warming and Water Availability


Source: Stern Review on the Economics of Climate Change

Global warming will increase water availability in the Sahel, India, and China under this scenario. Will parts of the Sahara become green again? Will the water table in India stop falling? Will the water shortages in Northeast China disappear? Would the people who developed this model bet serious money on it?

What it does illustrate is the need to focus on local and regional effects. “Global warming” is not a useful guide to local action.
