4. Midwest Flooding (Part One, Spring)In late March, flooding was blamed for at least 17 deaths in Missouri, Arkansas, Oklahoma, Texas, Indiana, Ohio, Kentucky and Illinois. A slow-moving storm system brought rains in excess of 10 inches to the region. These rains, combined with melting from unusually heavy snows in the winter, led to the floods.Global Warming Link: Global warming causes higher temperatures and more water vapor in the atmosphere. In winter, this means more moisture and heavier snows and, in spring, it means earlier and quicker snow melt and risk of heavier rainfalls. This melting, combined with heavy and multiple rainfalls, can lead to greater risk of flooding. Expert: Kevin Trenberth, trenbert@ucar.edu, 303-497-1318 Consensus Science: "One of the clearest trends in the United States observational record is an increasing frequency and intensity of heavy precipitation."
