Can you please tell us what definition of extreme precipitation
your shop used in developing your report, for both snow and 
rain?

Do you have this report up at a web URL for all to see?

>Grand Rapids, Michigan­Scientists have said for years that global warming was ?loading the dice? when it comes to increasing the frequency of severe storms, and a new Environment Michigan Research & Policy Center report makes it clear that Michigan is already experiencing extreme downpours much more frequently.  Specifically, the new report found that storms with heavy rainfall are now 18 percent more frequent in Michigan than they were 60 years ago.

Using data from 3,000 weather stations and a methodology originally developed by scientists at the National Climatic Data Center and the Illinois State Water Survey, the report identifies storms with the greatest 24-hour precipitation totals at each weather station, and analyzes when those storms occurred.

At the state level, 40 states show a significant trend toward more frequent storms with extreme precipitation, while only one state (Oregon) shows a significant decline.

>These findings are consistent with the predicted impacts of global warming.  Scientists expect some parts of the United States to receive more precipitation as a result of global warming, while other parts receive less.  But regardless of the trend in total precipitation, scientists predict that the rain and snow that does fall will be more likely to come in big downpours and heavy snowstorms.

>Rubley was careful to note that an increase in the frequency of extreme rainstorms does not mean more water will be available.  Scientists expect that, as global warming intensifies, longer periods of relative dryness will mark the periods between extreme rainstorms, increasing the risk of drought.  For example, the Intergovernmental Panel on Climate Change (IPCC) predicts that, under a scenario of intense warming, the percent of land enduring severe drought globally could be 30 times greater by the end of the century than it is today.

(S. 2191), a global warming bill introduced by Senators Lieberman (I-CT) and Warner (R-VA).  While recognizing the important efforts of the bill?s supporters on this critical issue, [Environment State] said that the legislation must be significantly strengthened to address the challenge of global warming.  Specifically, the bill?s current pollution reduction targets fall short of what the science says is necessary to avoid the worst effects of global warming, and the bill gives away far too many subsidies to dirty and dangerous energy sources.
