"Katrina's Real Name is Global Warming"

It’s very clear that global warming does not make more hurricanes, but it makes hurricanes much stronger. And that’s because hurricanes take their energy from the temperature of surface waters...if we look at some other events that have been happening the same year, not necessarily hurricanes, but we had a two-foot snowfall in Los Angeles in January. We had 37 inches of rain in one day in Mumbai, India. We had this horrendous heat wave with 120 degrees in Arizona. We have the Missouri River just about empty because of a prolonged drought. All of these, including the intensity of hurricanes, are signatures of the warming of the planet.
