An awful lot of scientists don't agree with AGW. Myself among them.
As a scientist who actually experiments and reports data, I can tell you that a look back at past data is only meaningful if you have the full picture, which I don't believe we do. And, it cannot give you solid conclusions because you are not able to run experiments under controlled conditions.
I don't know how we can so firmly state that warming trends we see are solidly from us, but then we struggle to explain burps and changes in that pattern. If we understand everything so well, we should see all of these coming.
