Katrina caused by global warming?

The environmental wackos are trying to convince people that Hurricane Katrina was caused by global warming, which in turn was caused by humans living their lives, which in turn was caused by President Bush not forcing the Kyoto Protocol on us.

Let's do a quick fact check.

Global warming has supposedly happened over the past 50 years. However, the year which still holds the record for the most named storms was 1933, well before human-caused global warming supposedly started. The most deadly hurricane was way back in 1900. Katrina struck a much more densely populated region, but the death toll is likely to be smaller than the 1900 storm which struck Galveston. There have been major storms just as powerful as Katrina every year for as long as we have records. In other years we were just more fortunate about where they struck.

There is no evidence to show that human activity has caused any change to the global temperature, or that any change is outside of the normal cyclical variation.

Sorry tree huggers, your story isn't holding up.
