However, the earth is not currently warming half as much as people think, considering that:
-This winter, much of the ice lost in the Arctic has come back
-The last two years there were hardly any hurricanes in the Caribbean, resulting in a massive drought in the American south
-Baghdad had snow
-Hundreds of people died in Vietnam this winter from a huge, unexpected freeze
But, if it ends up that we really are having substantial global warming, it still isn't man-made -- the sun is going through a heat cycle. Right now, Mars is experiencing global warming as well: its polar ice caps are melting! So is that caused by automobiles and factories on Mars?

The President of the Czech Republic recently said that the global warming scare is the new Communism, designed by big-government advocates wanting control over every aspect of people's lives and activities. Having lived under the control of the Soviet Union, I guess he knows Communism when he sees it. We're seeing it right now with the recent U.S. federal ban on incandescent light bulbs, forcing us to use toxic, mercury-filled florescent bulbs. Is this trip really necessary?
It's time to get back to the principles that made the free world great: that we are endowed by our Creator with certain inalienable rights, that among them are life, liberty, and the pursuit of happiness. And none of that is causing global warming.
It's a good discussion though.
