Okay. Apparently that does track with earth average data. Sorry.
Even so, the manmade portion of that increase is ridiculously small.
Massive fluctuations in carbon dioxide content have taken place throughout geological history due to geothermal activity. Fluctuations that dwarf any we could ever produce merely by burning oil.

If these numbers are accurate, then mankind has produced a piddling effect compared to natural fluctuations over history.
Even assuming we could stop this warming by ceasing consumption of fossil fuels, is it really worth returning to the middle ages, or wrecking the economy in pursuit of far less efficient and hard to produce synthetic fuels?
Even assuming the worst possible fire and brimstone prophecy of the global warming lobby, sea levels rising, rainfall patterns shifting, ect, are far easier to deal with with a strong economy than providing for the world will be with a medieval economy. Sea-walls to hold back the 11 mm/year oceanic rise are fairly easy to build. We can turn deserts into farmland, irrigate and terraform entire continents, move hillsides, ect with steam and internal combustion power. We are more at the mercy of nature (even assuming the warming would stop if we stopped industry) under medieval economies where we have no such artificial labor available, and far less productive agriculturally.
I still maintain that it is ridiculous to blame those hurricanes on global warming, since hardly any warming has taken place yet. Effects such as these couldn't be generated by one degree of difference in atmospheric temperature since the pre-industrial era. Furthermore, if it were the case, then we should have seen a steady increase in the frequency of such storms over the industrialized era. Instead, we have a few random years where the tropics get hammered particularly hard.
One more thing, wouldn't it make sense for temperature gradients to decrease, and therefore hurricane frequency to decrease under global warming? Wouldn't it make sense for the atmospheric concentration of water to increase, rather than decrease under a warmer atmosphere? (More rainfall, not continent spanning deserts?)
