"not a problem if it only affects the Blue States." Interesting political theory.... But, if waters rise, I seem to remember Florida, Louisiana, Mississippi, and Texas having a lot more low-lying coastal and riverine areas then NY or CA....

Global warming debate is over, UW prof says Calls new study as solid as proof that smoking causes cancer By Aaron Nathans March 3, 2005 A new study out of California makes it clear that human actions are causing global warming, said a University of Wisconsin-Madison specialist in atmospheric and oceanic sciences. The study, which shows people are responsible for the increase in temperature in the oceans, is another piece of strong evidence that global warming needs to be addressed, said Galen McKinley, an assistant professor at UW-Madison. "The fact that humans have a distinguishable impact on the climate system, that is becoming very hard to refute," McKinley said. The study, by scientists at Scripps Institution of Oceanography at the University of California, San Diego, was released in mid-February. It used a computer model and observational data to measure the penetration of greenhouse gas-influenced warming in the oceans. Increased ocean temperature is significant because it can melt glaciers and taint the water supply. Tim Barnett, one of the lead researchers, said in a written statement: "This is perhaps the most compelling evidence yet that global warming is happening right now and it shows that we can successfully simulate its past and likely future evolution." Global warming will produce broad changes that will affect regional water supplies, especially those affected by faster glacier melting in the South American Andes and in western China, he said. It could put millions of people at risk of losing safe summertime water, he said. Global warming is likely to create a water crisis in the western United States within 20 years, Barnett said. Barnett said the study "suggests that these scenarios have a high enough probability of actually happening that they need to be taken seriously by decision makers." The scientists tested other factors, such as the sun and volcanoes, running them through the computer model to see what affect they had on the ocean's temperature. But only when human activity was fed into the computer model were the scientists able to reproduce the effects seen in the ocean. McKinley said that about 10 years ago, people finally stopped arguing over whether tobacco causes cancer, accepting scientific research that it in fact does make people sick. People should now be having the same realization about global warming, she said. "It's not a debate anymore. Now the question is what we do about it," she said. Some of the first changes that need to be made include reducing emissions in motor vehicles, she said. Drivers could go a long way toward doing that by using hybrid cars, which cut the use of fossil fuels, she said. "It doesn't mean you have to give up seeing Grandma three hours away on the weekend," she said. "If we frame the debate, global warming is occurring, what are we going to do about that, things that wouldn't hurt? Those are the things we should do. Things that would require a change of mentality, but wouldn't change our lifestyles." madison.com
