Ross McKitrick was so upset about a paper ‘Learning from mistakes in climate research’(Benestad et al., 2015) that he has written a letter of complaint and asked for immediate retraction of the pages discussing his work.
This is an unusual step in science, as most disagreements and debate involve a comment or a response to the original article. The exchange of views, then, provides perspectives from different angles and may enhance the understanding of the problem. This is part of a learning process.
Responding to McKitrick’s letter, however, is a new opportunity to explain some basic statistics, and it’s excellent to have some real and clear-cut examples for this purpose.

This is a second post related to the new Marvel et al (2015) paper. The first post dealing with the substantive content is here.
What with #AGU15 going on, and a little bit of overlap in content with Shindell (2014), NASA wasn’t particularly keen to put out a press release for the paper, but we did get a ‘web special‘ put out on Friday Dec 18th, the last day of AGU and a few days after the paper appeared online. I’ve been involved with many similar releases for papers and it is always a struggle to concisely say why a paper is interesting while not overselling it or being too technical (which is why only a small fraction of papers get press releases at all).
As we’ve previously remarked about other people’s press releases (eg. Stainforth et al or Willerslev et al), properly calibrating the aspect of a release that will get picked up by the media can be tricky, and so it proved in this case.

There is a lot of great science that will be freely streamed via AGU On-Demand (registration required), and there’ll be a lot of commentary using the hashtag #AGU15. Many posters will be available online too. A few highlights have already been discussed by Victor Venema related to the surface temperature station datasets, but there’ll be much more on offer if you dig deeper.
As the week goes on, we’ll link to anything good we see, and we’ll be happy to host any commentaries that anyone has on specific climate sessions or talks.
Guest commentary by Stephan Lewandowsky, James Risbey and Naomi Oreskes
The idea that global warming has “stopped” has long been a contrarian talking point. This framing has found entry into the scientific literature and there are now numerous articles that address a presumed recent “pause” or “hiatus” in global warming. Moreover, the “hiatus” also featured as an accepted fact in the latest IPCC report (AR5). Notwithstanding its widespread use in public and apparent acceptance in the scientific community, there are reasons to be skeptical of the existence of a “hiatus” or “pause” in global warming [Ed: see also this previous post]. We have examined this issue in a series of three recent papers, which have converged on the conclusion that there is not now, and there never has been, a hiatus or pause in global warming.
