    The US Has Had 285 Hurricane Strikes Since 1850
    Team climate moron tells us that the US is now vulnerable to hurricanes, due to climate change.

    The US has always been vulnerable to hurricanes. Eighty-six percent of US hurricane strikes occurred with CO2 below Hansen’s safe level of 350 PPM.

    Do we know when the CO2 level reached 350?

    I don't.

    But judging from the graph, which is based on actual, real science (because the AGW cultists can't tell), it looks like the more CO2, the fewer hurricanes.

    But that contradicts their dogma.

    The reason I ask is if, for example, it only reached that level last year, then you'd be comparing 160 years to one.
    Drawing a firm conclusion from one graph is dangerous.

    Per Rat's link, CO2 has been above 350 ppm for 24 years now.

    So is it true we never had a hurricane until 1950 or thereabouts.
    We never had one until the baby boomers started making money
    and the cars showed up on the road.
    How about the few World Wars we had way back when....
    Back when the factories were going non stop spewing their filth into the air.
    We now have more safety standards then ever before.
    All of a sudden man is the cause of Hurricanes.

    Pa leeeeeze.

    Yep, looking at that it looks like the incidence of hurricanes hasn't increased at all.
    What about the intensity?
    Isn't one of the warnings also that they will become more dangerous as the warming seas provide more energy?

    Other articles I've seen show that Sandy really wasn't all that intense. It was just big.

    Not sure what dave is talking about now, since there's nothing in AGW theory about more hurricanes. I do see he's grabbing stuff from political crank Steve Goddard, which is never a wise idea.

    The thing that affects hurricanes hitting the northeast USA is the Arctic Oscillation, whether it's positive or negative. A positive Arctic Oscillation parks a low over Greenland, which sucks hurricanes that go north back out into the Atlantic. A negative Arctic Oscillation parks a high pressure blocking ridge over Greenland, which shoves the hurricanes westward into the USA.

    For most of the last 40 years or so, there's been a positive Arctic oscillation, meaning few hurricanes hitting the northeast. Prior to that, there were more hurricanes hitting the northeast.

    In the last couple years, the Arctic Oscillation has gone mostly negative. Why? Good question. Some theories show a lack of sea ice driving the more negative condition. More investigating is needed on this recent change, so it's in progress.

    (Cue conspiracy theory kook responses now.)
