How to counter a counterer

I first read “Friends of Science” first to get a viewpoint of what seemed to arguing against the idea of global warming.
I found their arguments interesting, preventing facts about apparent arguments on why it is important to focus on global warming. They came from sources that didn’t really address the economy at all, a big factor in environmentalists accusing those who didn’t believe in global warming being only led by industrial influences. They presented a compelling argument in a professional manner throughout their website, although their tone seemed a little jaded towards the UN having too much jurisdiction over environmental issues, usually a stance that is not relevant with mainstream environmentalist thought of government intervention and regulation (then again, the early environmentalists didn’t think too highly of the government, or in Wendell Berry and Thoreau’s case, voting). Finally, they shifted the focus that we should center on air and water pollution rather than global warming, which are very legitimate topics that ought to be focused on well.
I then looked at Grist’s website, which was run as a way to counter basically every topic that the Friend’s made a fact. In a more informal manner, it basically broke down arguments that sounded legitimate on why CO2 isn’t a factor and gave links and factual information why it was indeed a factor. While the Friend’s were probably able to delegitimize nearly every uneducated environmental hippy on their viewpoints on the environment, Grist’s article was able to delegitimize every point that was used as ammo.
In the end, I found the Grist site more convincing simply because it’s purpose was the refute a basical rebuttal to global warming arguments. It was a counter to a counter (by the Friends). It was also focused only on global warming rather than veering a different direction (which the Friends did). A very useful site when I’ll have to argue with conservatives in the future when they give me equally legitimate sounding reasons like the Friends, although this time I’ll do my best not to sound like an uneducated hipster (not green enough to be a hippy)
