#1 The human population curve has been exponential since at least the

#2 It is NOT expoential, and not even concave up. It's curving down,
it has been since 1989. In fact, it's an S curve, with an exact 180
degree symmetry about 1989 satisfying the equation
P(1989-t)+P(1989+t)=10.39 billion within +/- 5 million; and an upper
limit of 7.8 billion.

So ...? Global warming as a
function of human activity
has affected climate change?

It doesn't matter. The only relevant fact is that it exists, and the
predicted consequences of it are already past tense.

If ice is melting at the poles,
then there's more water vapor
in the air, and potentially more
rainfall, or at the least, higher
humidity.

Simplistic reasoning of a mere human is no substitute for detailed
climatological models. Leave the extrapolation to the professionals.

The net effects that are known a increased severity and frequency of
storms (particularly with the greater heat in the oceans as a driving
force). That's present, with 2004 and 2005 each being record years for
hurricanes. It's probably also the case for tornadoes.

Adjusting tornado reports for the long-term increase in reporting of
weak tornadoes (we report short-lived, weak tornadoes better than in the
past, but strong tornado reports don't show the same kind of changes),
2005 is in the lower 10% of years, more than 200 tornadoes behind the
normal to date of ~1070. 2004 had the most tornado reports on record.

In fact, just a month ago, the entire Milwaukee metro area barely
missed being completely trashed by the simultaneous occurrence of 28
tornadoes. The devastation looked like a war zone, as bad as New
Orleans; debris and other remains of personal belongings, property
being found as far as 70 miles away. Had the storm kept on the ground
for another 20 miles further to the East, instead of the destruction
being of the sparsely distributed and populated rural regions, it would
have been of the metro area and what happened in New Orleans wouldn't
even be a blip on the radar. In recent times, there has even been
tornadoes in the winter.

There have been tornadoes in the US in winter as far back as we records.
Wisconsin was part of the 24 January 1967 and 1 December 1970 outbreaks.

It is exceedingly unlikely that the tornadoes could have caused as much
damage as the hurricane did, even in a worst-case scenario. Adjusted
for inflation and national wealth, the costliest tornado is US history
(1896 St. Louis) would be $3B in today's dollars. Put an outbreak like
the 1974 outbreak (148 tornadoes) with an 1896-like event and you won't
top $20B.
