Explaining different results for climate sensitivity and the low bias

This was a month late at WUWT but better late than never I suppose.  WUWT's current leading blog writer, Eric Worrall, has written about a paper published last month in Nature Climate Change (archived here). The authors, Mark Richardson, Kevin Cowtan, Ed Hawkins and Martin B. Stolpe, had a look at how temperature records are sampled. They found that slower warming regions are preferentially sampled, which means that observations are biased low.

The authors reported that after adjusting for biases, and using observations, the transient climate response (TCR) is 1.66 °C with a 5% to 95% range of 1.0 to 3.3 °C. This is consistent with that derived from climate models considered in the AR5 IPCC report.

Anthony Watts blows his dog whistle to round up the cosmic ray lynch mob

Ha ha ha. This is hilarious. There's an article by Anthony Watts on his climate science denier blog WUWT where he writes (archived here):

A peer reviewed Nuccitelli smackdown

Reply to “Comment on ‘Cosmic-ray-driven reaction and greenhouse effect of halogenated molecules: Culprits for atmospheric ozone depletion and global climate change’ by Dana Nuccitelli et al.”

Anthony copies the abstract of the reply to the comment but nothing else apart from the above and a link to the reply. He leaves it up to readers to try to find the original paper, figure out who wrote it and see if they can lay their hand on the comment. (The reply was published a month ago, so Anthony is losing his touch.)
