I should also say on this topic that few things are more amusing than people who claim to be scientist but deny AGW. By now for example the Mann paper is the most peer reviewed scientific paper in history. Everyone who is anyone remotely related to the field has been up and down the paper and it has withstood the test of that scrutiny. No one claims it is false.

Well no one who actually has a science degree does.

Denying AGW is at this point as scientific as denying Evolution or special relativity. Someone who claims to know anything about science but denies the reality of AGW has the credibility of someone who claimed that he is a rabbi and that pork is kosher. It is that well established.

Simply put, if they say they have a science degree and that AGW is not real, they are either lying about the degree or a paid stooge because no one with any actual expertise or validity in this field would tell such a lie than a legitimate rabbi would tell you that pork is kosher.
