Rising Temperatures May Cause More Katrinas
Small increases in temperature found to add power to storms in the Atlantic.
Using modeling data focused on the conditions in which hurricanes form, a group of international researchers based at Beijing Normal University found that for every 1.8ºF (1ºC) rise of the Earth's temperature, the number of hurricanes in the Atlantic that are as strong or stronger than Hurricane Katrina will increase twofold to sevenfold.
The study points to a gradual increase of Katrina-like events. The warming experienced over the 20th century doubled the number of such debilitating storms. But the ongoing warming of the planet into the 21st century could increase the frequency of the worst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean with multiple Category 5 storms every year.
