The Earth is a complicated rock revolving and revolving around our sun. One of the 'key' elements that stabilize the climate are teh 'winds' of Earth. The winds have an effect on the ocean surface currents. The theorist that wants to add some hockus-pockus to the tragedy of Rita and Katrina never discussed the winds. One cannot talk about warming Earth without discussing it's ocean of air as well. It's a darn shame people have to lie and endanger life for a political agenda that is bigoted, racist and counter productive to democracy and freedom.
