Climate Change Impacts on America
Ecoshock Show 080815
Top IPCC organizer & U of Arizona Professor Jonathan Overpeck speech at Washington U. given on April 1st, 2008.
After updating the world climate report, Overpeck predicts climate impacts on North America.
His focus, on the two worst climate problems for America:
1. Rising seas. More than half of Americans live within 50 miles of the sea coast. Many American cities, like New York, and States, like Florida, may be flooded by rising seas (plus storm surges) within the experience of our children - or sooner. The implications are enormous.
2. The drying of the West. Already well underway. Dry soils, and 20 percent of normal rainfall this spring (and hot temperatures) are behind the North California fires we now know. Overpeck explains why tree species are dying, and the great droughts that have driven humans from the South West in the past. This time, we have triggered this phenomenon, as the Jet Stream moves North, the former rains move with it.
Overpeck gives a clear explanation, with predictions for Americans that sound to me a lot like what has hit Southern Australia. The possibility of centuries-long drought.
