I think the United Nations report moved the debate ahead significantly. Not sure what Al Gore, Politically Correct, and Creationism have to do with scientific debate; they are examples of the problem, not a path forward in having a healthy debate.
What do you think of Marc Morano? The author of the first link posted has an interesting history, spanning Exxon, Swift Boats, Rush Limbaugh, and so on.
I don't believe in any way that humans are the sole cause of global temperature changes. However, we should clarify the specific terms used. The
United Nations Framework Convention on Climate Change (UNFCCC) uses the term "climate change" for human-caused change, and "climate variability" for other changes. In that sense, by that definition, then yes, human activity is the cause of it all. In the broader sense, no, of course humans did not cause it all, as evidenced by ice core samples over the past 800,000 years, which in itself is a drop in the bucket in geological age.
