"The frequency of downpours and heat waves, as well as the power of hurricanes, has increased so dramatically that "100-year storms" are striking some areas once every 15 years, and other once rare events keep returning like a bad penny. As a result, some climatologists now say global warming is to blame.
... In a warmer world, air holds more water vapor, so when cloud conditions are right for that vapor to form droplets, more precipitation falls. Man-made climate change is also causing more droughts on top of those that occur naturally: attribution studies trace droughts such as that gripping the Southwest to higher sea-surface temperatures, especially in the Pacific.
...Hurricanes have become more powerful due to global warming. For every rise of 1 degree Celsius (most of it man-made) in surface temperatures in the tropical Atlantic, rainfall from a tropical storm increases 6 to 18 percent and wind speeds of the strongest hurricanes increase by up to 8 percent. As the new report acknowledged, "the strongest storms are becoming even stronger." Atmospheric conditions that bring severe thunderstorms (with hail two inches across and wind gusts of at least 70 miles an hour) and tornadoes with a force of F2 or greater have been on the rise since the 1970s, occurring about 8 percent more often every decade. Get used to it, and don't blame Mother Nature." LINK
