global warming and the USA

Well, its now out and in the media. The US govt has covered up global warming to its population over the last few years.
Bush an co have been consistent in denying it existed and have been editing technical publications to lay doubt on its existence , by for example replacing 'will' for 'may' in the sentence ' global warming will be a serious problem in the future ' Govt departments that tried to stop the cover up have had their heads of the section responsible sidetracked to other postings ,or had their contracts terminated .
Even last week Bush stated that the Gulf temperature was not responsible for the ferocity of hurricanes and im assuming that he left out the word 'totally' from the report he could say he got it from.
The water temperature is obviously responsible . You dont get hurricanes under a water temperature of [I think ] 25C .
Hurricanes use the water vapour pressure to grow . Im not a meteorologist so it could just be hurricanes just use the latent heat of the water to power themselves , in which case the power increase would be proportional to the water temperature . It is some form of function of the vapour pressure also [ie how easy it is to 'boil' the sea .
In which case the figures are :
temp pressure
0 deg C 4.6
10 deg 9.2
20 17.5
25 23.7
30 31.8
35 42.2 mm Hg [based on pure water not sea water, but the ratios will be the same]
in which case from 25C to 35 C implies a doubling of power .
The Gulf temperature is now the same as this time last year. [google gulf water temperatures for the govt publication] . So it looks like Katrina II could be on its way over the next few months .
Bush's stance is that his chums are in the energy business so he's got to look after them ,and its starting to look like it doesnt matter too much to him if the US loses a few cities in the meantime .
I hope im wrong , but it really does look as if New Orleans is going to be severely truncated as a city within a couple of years .
