SHeldon,

...

To give just one example, Ed falsely claimed (on the

global warming talk page) that the National Association of Science predicted a looming ice age in 1975. I corrected him, and to his credit he backed off of his error. <<

Few of us are perfect. Getting corrected and accepting a correction is a good sign, not a bad one.

Do you think that Mars is experiencing global warming? If so, why?

For some interesting views on global warming, others may wish to visit http://www.iainmurray.org/MT/archives/000345.html , http://news.bbc.co.uk/1/hi/sci/tech/3152424.stm and http://www.russiajournal.com/news/cnews-article.shtml?nd=40617 for coverage of the World Climate Conference. One of the most newsworthy reports so far has been a statement from the head of the Russian Academy of Science that the only people who would be affected by the abandonment of Kyoto "would be several thousand people who make a living attending conferences on global warming".

Addressing consensus, http://www.sepp.org/glwarm/noscicons.html suggests that it wasn't there in 1991. http://www.geocities.com/abcolombo/sep00/092200f.htm looks interesting.

It appears reasonable to suggest that there is not a consensus among scientists that global warming is caused by carbon dioxide emissions.

Personally, I believe that there is global warming. Knowing why is a much harder problem.
