Friday round-up

They knew all along?
A recent story in NYT: ‘Industry Ignored Its Scientists on Climate‘ has caught our attention.

Update: Marc Roberts’ take:

Latest skeptical song from Singer

This week, the annual European Geophysical Union (EGU)’s general assembly was held in Vienna. Friday afternoon, I went to one of the conference’s last talks to learn about the latest news from the climate skeptics (have to keep an open mind…). It was probably the talk with the smallest audience in the whole conference (see the photo, but note there were a couple of individuals who were not captured by camera), despite an unusually long slot (30 min) allocation.

And not much news, I’m afraid, apart from that SEPP plans to release it’s NIPCC’09 in May. I understand it will be a thick report (800 pages?). The main messages were (a) that GHGs were unimportant – allegedlly supported by Douglass et al. (2007), and (b) solar activity was the main reason for the recent global warming and the mechanism involved galactic cosmic rays (GCR).

I asked Singer how he could explain the most recent warming when there is no trend in the GCR-flux or other indices of solar activity since 1952. He countered by saying he was glad I asked him this question, and announced that he had done his thesis exactly on the topic solar wind and GCRs.

So I had to answer that I had written a book about solar activity and climate, and I repeated my question. He could not answer in the end – other than saying that we have to look at the data. I told him that we already have looked at the data (e.g. Richardsson et al 2002; Benestad, 2005; Lockwood & Frohlich, 2007), so I recommended him to read up on RC.
