And Don't Forget Shaviv

The Hebrew University debate on Global Warming | ScienceBits: "In my short presentations, I stressed a few major issues. First, there are no fingerprints proving that 20th century warming is necessarily human. Second, once you check the details, you find that there are notable inconsistencies. In particular, the AGHG theory predicts warming over the whole troposphere, while in reality, only the ground appears to have warmed over the past few decades, and that Earth's climate response to volcanic eruptions is significantly smaller than predicted by computer models. This is because these models tend to have an exaggerated climate sensitivity. Third, the only reason we can attribute the warming to humans, is because allegedly there is nothing else to blame, but there is, the increasing activity of the sun. And then I quickly showed some of the evidence showing that the sun affects climate through the cosmic ray climate link."
