The science is settled (?)

Couple links here. LA Times editorial interview by Eli Kintisch:

And an NPR interview with Mr. Kintisch:

The premise of these articles is that cleaner air may actually lead to more global warming. Now, I'm not an expert in this area so I'm not qualified to say one way or the other. My point is to simply point out that there is still a lot confusion about what causes global warming and what we should be doing about it. The words "the science is settled" (example: "The science is settled, Gore told the lawmakers.") are like nails on a chalkboard to me--because they are demonstrably false.
