The number of hurricanes that develop each year has more than doubled over the past century, an increase tied to global warming, according to a study released Sunday.
"We're seeing a quite substantial increase in hurricanes over the last century, very closely related to increases in sea-surface temperatures in the tropical Atlantic Ocean," says study author Greg Holland of the National Center for Atmospheric Research in Colorado.

Robert Lund, professor of mathematical sciences at Clemson, along with colleagues Michael Robbins and Colin Gallagher of Clemson and QiQi Lu of Mississippi State University, studied changes in the tropical cycle record in the North Atlantic between 1851 and 2008.

“This is a hot button in the argument for global warming,” said Lund. “Climatologists reporting to the U.S. Senate as recently as this summer testified to the exact opposite of what we find. Many researchers have maintained that warming waters of the Atlantic are increasing the strengths of these storms. We do not see evidence for this at all, however we do find that the number of storms has recently increased.”

Global warming is causing more frequent hurricanes in the North Atlantic and Gulf of Mexico, according to a study from the National Center for Atmospheric Research.

The increased frequency of tropical cyclones ``is largely a response'' to a 1 degree Celsius rise in sea water temperatures since 1905 that was caused by greenhouse gases, the study found. Since 1995, the North Atlantic has experienced an average of 15 tropical storms a year, of which eight became strong enough to be called hurricanes. That compares with 10 tropical storms and five hurricanes per year from 1930 to 1994, the report says.
and on and on and on. Dont try to pretend that it didnt happen

New As the IPCC report said...
There are arguments on both sides. It's not settled science yet, at least in part because of difficulties with the older data. But the IPCC statement from 2007 is holding up - the average number of storms seems likely to drop, but their severity may increase.

For instance, a recent Science article from January 2010 (from people at NOAA): http://www.sciencema...full/327/5964/454

Modeled Impact of Anthropogenic Warming on the Frequency of Intense Atlantic Hurricanes

Rising sea-surface temperatures (SSTs) and a possible increase in Atlantic basin hurricane activity since 1950 have raised concern that human-caused climate change may be increasing Atlantic hurricane activity. Increasing amounts of greenhouse gases are a likely factor in the recent warming of tropical Atlantic SSTs (1–3), although internal variability (4) and reduced aerosol or dust forcing (5, 6) may have also contributed. Some statistical analyses suggest a link between warmer Atlantic SSTs and increased hurricane activity (6–8), although other studies contend that the spatial structure of the SST change may be a more important control on tropical cyclone frequency and intensity (9–11). A few studies (6, 8, 12) suggest that greenhouse warming has already produced a substantial rise in Atlantic tropical cyclone activity, but others question that conclusion (9, 11, 13).

[...]

Our results suggest that a significant anthropogenic increase in the frequency of very intense Atlantic hurricanes may emerge from the background climate variability in the latter half of the 21st century, despite a projected decrease in the overall number of hurricanes. These findings are dependent on the global climate models used to provide the environmental conditions for our downscaling experiments. Future studies should reassess our findings using both updated climate model projections and improved hurricane simulation models.


I'm not going to argue that some people said the number of storms may/will/are increasing. That's not what the IPCC report says, though.

By the time I'm 140, we'll know who was right.

HTH.

                 hmmm - (boxley) - (1)
