How to respond to the warming is a matter of intense political, scientific and economic debate worldwide.Alley said he was upbeat about global warming because enough clever people existed in the world to find other reliable energy sources besides fossil fuels. He said people can get rich finding marketable alternatives to fossil fuel. “Wouldnt it be useful if the United States were to have a piece of the action. Wouldnt it be useful if some bright students from University of Vermont were to have a piece of the action,” Alley said.Alley said that Europe and parts of eastern North America could in a matter of a few years revert to a cold, windy region, like the weather in Siberia. Such shifts have occurred frequently over the millennia, Alleys research shows. A gradual change in atmospheric temperature, such as global warming, could push the climate to a threshold where such a shift suddenly occurs, he said.Alley told his audience of about 200 people in a University of Vermont lecture hall Wednesday evening that he couldnt predict if, when or where sudden shifts toward cold, heat, drought or water could occur under global warming, but it is something everyone should consider.“This is not the biggest problem in the world. The biggest problem in the world is getting along with each other. But its part of that because were not going to get along with each other if were not getting along with the planet,” Alley said.1.
