...actually, big storms are caused by cool atmosphere, and warm waters. The water evaporates out of the ocean. The warm, moist air rises into the atmosphere where it encounters cool air. Blammo! it condenses to form....Yep, that's right, rain!!! The bigger the temperature differential, the more convection, and the bigger the storm. It's the basic laws of physics, and has nothing to do with our favorite scapegoat...global warming
Typically, when we have cool summers, we get big storms. This past summer has been a little bit cooler than the past two (when we didn't get any big hurricanes).
Yes, I believe that the earth is warming some, but if it's being caused by human activity or not is highly doubtable, especially when one considers other variables that can affect global temperature, like the our orbit around the sun, which can vary by several hundred miles in either direction, the temperature of the sun, which isn't stable either, then there's volcanic and geothermal activity....the list goes on! Now, I'm not saying that this is a free pass to go waste all the energy and pollute all you want, because there are other problems that are caused by reckless consumption and pollution, especially with health!
