I don't know now, but Bush was definitely a Global Warming denier, so i take your point that some deniers are more dangerous than others.
I have some conservative views and some liberal views so I don't really take either camp. But as far as human caused global temperature changes, I am still not convinced.
In the past the Earths average global temperature was not a few degrees warmer but it was over twenty degrees warmer than it is now. Most of the planet was covered in tropical forests. 90% of all species that have ever existed are extinct. So even if global temperatures rise things will either be forced to adapt or die. This is not something new.
We know that solar activity is picking up, the sun is actually getting brighter than previously recorded. There is no disputing this information. A sun that puts out more energy will ultimately effect how much solar radiation hits the Earth thus causing it to become slightly warmer.
The Earth's crust actually absorbs carbon dioxide from the air and locks it into the rocks. They don't even need to be molten to do this. The carbon dioxide levels were over 500 times higher in the past than they are now and it was due to millions of years of rocks locking the gas into them. This is why when volcanoes explode they give off lots of carbon dioxide. The molten rock releases the gas. When they explode they give off more CD than all the combined cars do in a year.
Global temperature readings of the other planets in our solar system has also been measured to be on the rise as well. So I guess driving your car is making Mars warmer as well.
The leading people who are pushing for global temperature caused by humans are political leaders who want to impose new taxes so the government and themselves make more money. It is known that Al Gore fraudulently paid for some scientists to claim global temperature rise was due to human activity. Some of these scientists have come forth recently to admit to the findings were doctored to give the results that were wanted rather than how they really are.
I won't deny that humans are extremely wasteful and take huge shits on this planet with how we go about consuming natural resources but as far as effecting global temperatures I am not convinced. There are just too many natural factors involved to say.
We know that the Earth's past temperatures have swung widely from far warmer to far colder. To say humans are speeding up this process is just egocentric.
