They have just finished their opening statements. First up was
His last point did deal with the science. He said the main question was how much warming would you get if you increase CO2. He used two examples, first dolomitic rock from 750 million years formed at the equator near a glacier. The dolomitic rock indicated a high CO2 concentration but the glacier indicates a cool climate. His second example was from a paper by Pinker in 2005.
I was going to dissect these, but in fact Tim did it in the debate. First, conditions were very different 750 million years ago, including the solar output. Second, we do not really have a good idea of the extent of glaciers and dust conditions to allow us to see what really was going on.
However Tim's refutation of Pinker was classic. He played a clip from Pinker herself saying that Monckton was wrong in how he interpreted her paper.
I lost my feed for the next bit, but they are now taking questions and the first question was a doozie. I found it hard to hear but it seems he thought that CO2 was causing clouds. The second was about CO2 on mars. Anyway, I am going to stop blogging about it now. More tomorrow if I can find a recording somewhere.
