But there's no proof global warming is real, right?
Climate Change Desiccating the Planet, Researchers Conclude
The portion of our planet affected by serious drought has doubled in the last three decades, a new study suggests. Findings to be presented today at the annual meeting of the American Meteorological Society in San Diego, Calif., indicate that the fraction of global land characterized as "very dry" has increased from 10 to 15 percent in the 1970s to nearly 30 percent in 2002.
...The results reveal that widespread drying has occurred in large regions of Canada, Europe and Asia, as well as western and southern Africa, and eastern Australia. The U.S. experienced the opposite trend, exhibiting increased wetness over the past 50 years. By controlling for rain and snowfall, the scientists determined the amount of drying caused by increasing global temperatures, which lead to elevated rates of evaporation. They found that about half of the change is a result of rising temperatures, particularly in areas at northern middle and high latitudes. "Global climate models predict increased drying over most land areas during their warm season, as carbon dioxide and other greenhouse gases increase," says Dai. "Our analyses suggest that this drying may have already begun." --Sarah Graham
