Does Global Warming exist?

If so, how has it been measured, observed, and proven?

Three sources, two from the same website.  Yup, I've read those articles, too.  I've read thousands of articles on global warming over the past 15 years.  And I read the articles refuting Chriton's sources, as well as articles agree with them.

My challenge to you, since you like to find links: Provide 5 links to serious scientists not funded by any groups, entities, or individuals directly or indirectly related to any political or environmental movements, who are not funded by politicians, environmentalists, whose best interest is not served by swaying their results in any one direction for special favors, money, etc., and finally who all agree that global warming is a human-caused, imminent threat to the worlds' eco-systems, and we'll talk further (hint: News agencies isn't excluded from this).

I won't wait with baited breath, because you won't find it.
