abrupt-climate-change.txtSynopsis of Abrupt Climate Change: Should We Be Worried? Describes sudden cooling of climate that occurred 1200 years ago and again 8000 years ago. Explains how those changes are thought to have been caused. Sudden drops in regional climates could happen 2 decades from now. As in the past, temperature could cool 5 degree centigrade over a period of 10 years. There is evidence to suggest that conditions in the North Atlantic are setting up to initiate such cooling. The eastern U.S. and Europe could be affected for 100 years or more. Some regions such as the southwestern U.S. could experience prolonged drought. The consequences could be costly.
