    Hurricanes and tropical cyclones are fueled by warm water evaporating into the air. Ocean surface temperatures are up 0.9 degrees Fahrenheit (0.5 degrees Celsius) from about a century ago, a fact that may boost storm intensity. A recent study released in September in the journal Geophysical Research Letters, for example, found that hurricanes and tropical cyclones ramp up faster than they did 25 years ago. Globally, these storms reach Category 3 status, with winds up to 129 mph (208 kph), nine hours earlier on average than they used to, the study found.

    With warmer ocean surfaces comes warmer air above the oceans, Trenberth said. With warmer temperatures, this ocean air now holds about 4 percent more moisture than it did in the 1970s.

    "In general, we estimate it increases the risk that the intensity of hurricanes can be somewhat greater and particularly the rainfall from hurricanes is about 5 to 10 percent greater than it otherwise would be," Trenberth said. [Video: Hurricane Sandy's Intensity]

    In the case of 2005's Hurricane Katrina, which dumped at least 10 inches (25 centimeters) of rain along its track on the Gulf Coast, that means about 1 inch was attributable to climate change, Trenberth said. Sandy could dump similar levels of moisture over the Northeast.

    Trenberth added that "there are signs" that storms of Category 3 and above are becoming more common, but warned that hurricanes show tremendous natural variability from year to year, driven largely by climate patterns set up by El Niño.

    In other words, "We have no scientific evidence that what we are theorizing is true, but is sounds good to us, so we are repeating it as truth, when in fact it is likely just natural causes that are at fault."

    That's exactly what's going to happen.

    We see it played out over and over again. Whether locally or on a national level. In our local politics, when something unfortunate happens, if there's anything that can be used to further the agenda the cry goes out....

    WE'VE GOT TO DO SOMETHING!

    WE WILL DO SOMETHING!

    Another set of regs goes on the books, often without thought to negative implications, even for those endorsing those new laws. A couple of years ago our county commissioners laid out some code requirements to "resolve" a problem. A year or two later, it came back to bite them when they discovered they wouldn't be in compliance with their own law, if they did what they promoted to be another "solution" to yet another "problem".

    The thing that doesn't quite fit into that is the Long Island Express Hurricane of 1938.

    Or the hurricane of 1821 during which water levels rose 13 feet in one hour...

    Or the hurricane of 1893 which destroyed Hog Island.

    It rains one day, and the sun is out on another. Climate change.
