The ability to make predictions is the hall mark of a good scientific hypothesis. What ever the cause, the best models now predict that warmer oceans mean that powerful hurricanes are going to be more likely than in the past, and we are seeing it daily on the evening news. Here's an stunning prediction made exactly a year ago.

Global Warming Is Expected to Raise Hurricane Intensity
Global warming is likely to produce a significant increase in the intensity and rainfall of hurricanes in coming decades, according to the most comprehensive computer analysis done so far.
By the 2080's, seas warmed by rising atmospheric concentrations of heat-trapping greenhouse gases could cause a typical hurricane to intensify about an extra half step on the five-step scale of destructive power, says the study, done on supercomputers at the Commerce Department's Geophysical Fluid Dynamics Laboratory in Princeton, N.J. And rainfall up to 60 miles from the core would be nearly 20 percent more intense.
Other computer modeling efforts have also predicted that hurricanes will grow stronger and wetter as a result of global warming. But this study is particularly significant, independent experts said, because it used half a dozen computer simulations of global climate, devised by separate groups at institutions around the world. The long-term trends it identifies are independent of the normal lulls and surges in hurricane activity that have been on display in recent decades.
The study was published online on by The Journal of Climate and can be found at www.gfdl.noaa.gov/reference/bibliography/2004/tk0401.pdf.

And now from today's news:
This is global warming, says environmental chief
Super-powerful hurricanes now hitting the United States are the "smoking gun" of global warming, one of Britain's leading scientists believes.
The growing violence of storms such as Katrina, which wrecked New Orleans, and Rita, now threatening Texas, is very probably caused by climate change, said Sir John Lawton, chairman of the Royal Commission on Environmental Pollution. Hurricanes were getting more intense, just as computer models predicted they would, because of the rising temperature of the sea, he said. "The increased intensity of these kinds of extreme storms is very likely to be due to global warming."
"If this makes the climate loonies in the States realise we've got a problem, some good will come out of a truly awful situation."

Obviously the Bush administration can't admit to the science behind Global Warming; after all, they've fired all the people in government that were qualified to speak on the subject:
Bush and company blinded by pseudoscience
Consider global warming. The collective work of thousands of prominent scientists has led to a strong consensus that man's activities have already led to a hotter planet and that these greenhouse gas emissions, if continued at expected rates, will threaten ecosystems and the stability of our climate. One can count on two hands the prominent contrarians who believe otherwise -- skeptics who rarely, if ever, publish in the established venues of scientific literature -- yet time and again the Bush administration has chosen to downplay the consensus views, instead substituting demonstrably poor science by these contrarians that protects corporations that have heavily contributed to the Republican Party. (Only very recently has the president, after journalists twisted his arm leading up to the Gleneagles Summit, even admitted that mankind is partly responsible for warmer temperatures, but absolutely no action is planned as a result.) The administration -- and senators such as Republican James Inhofe of Oklahoma -- have stalled, diverted and ignored the mainstream consensus on climate change at every turn, Inhofe even having the audacity to call the overwhelming agreement on global warming "the greatest hoax ever perpetrated on the American people."
Bush and company blinded by pseudoscience
Perhaps, as the Bushies would have us believe, Global Warming has nothing to do with 'human' behavior at all, and this is the work of some kind of "Intelligent Design"...if so I would suggest that global climate change is either the work a demented intelligence, or a very sadistic intelligence. It probably doesn't matter at this point, if this is part of a devine "plan", an inevitable consequence of solar fluctuation, or just the sad by-product of a long and ongoing pattern of denial in certain really dumb segments of humanity. Regardless of what we might have done, could have done, should have done, it appears now that we really are screwed.
Global warming 'past the point of no return'
A record loss of sea ice in the Arctic this summer has convinced scientists that the northern hemisphere may have crossed a critical threshold beyond which the climate may never recover. Scientists fear that the Arctic has now entered an irreversible phase of warming which will accelerate the loss of the polar sea ice that has helped to keep the climate stable for thousands of years.
They believe global warming is melting Arctic ice so rapidly that the region is beginning to absorb more heat from the sun, causing the ice to melt still further and so reinforcing a vicious cycle of melting and heating.
