| Description | November 9th, 2008
As Jeff Master, our favorite meteorologist and hurricane blogger, wrote yesterday:
This year is now the only hurricane season on record in the Atlantic that has featured major hurricanes in five separate months. The only year to feature major hurricanes in four separate months was 2005, and many years have had major hurricanes in three separate months. This year’s record-setting fivesome were Hurricane Bertha in July, Hurricane Gustav in August, Hurricane Ike in September, Hurricane Omar in October, and Hurricane Paloma in November.
Because global warming will be cooking the Atlantic hurricane forming region year-round for the foreseeable future, we can expect this deadly record to be repeated many times. A recent study offered “the firmest evidence so far that global warming will significantly increase the intensity of the most extreme storms worldwide” (see “Nature: Hurricanes ARE getting fiercer — and it’s going to get much worse“).
Tropical cyclones are threshold events: If sea surface temperatures are below 80°F (26.5°C), they do not form. Some analysis even suggests there is a sea surface temperature “threshold [close to 83°F] necessary for the development of major hurricanes” (see “Why global warming means killer storms worse than Katrina and Gustav, Part 1“).
Global warming may thus actually cause some hurricanes and some major hurricanes to develop that otherwise would not have (by raising sea surface temperatures above the necessary threshold at the right place or time). |
