Eli Rabett covers the debate between Andrew Dessler and Richard Lindzen (video embedded at the link). Purportedly the former smoked the latter, though I haven’t watched the whole thing yet so can’t vouch for that.
Quoting Eli quoting Andy:
It all fits together (…). The key thing to look at is look for coherence, look for lots of evidence supporting a point and you will clearly see why scientists are convinced that the mainstream view of climate science is right.
The real question I want to address here is this question of how much does carbon dioxide warm the climate [not whether it does at all]. (…) We are going to use a standard measure which is how much warming would occur if we doubled carbon dioxide, so we are going to go through the math and do a very simple calculation that indicates that we might be screwed.
