A mistaken message from IoP?

Filed under: — rasmus @ 6 March 2010

The Institute of Physics (IoP) recently made a splash in the media through a statement about the implications of the e-mails stolen in the CRU hack. A couple of articles in the Guardian report how this statement was submitted to an inquiry into the CRU hack and provide some background.

The 1991 Science paper by Friis-Christensen & Lassen, work by Henrik Svensmark (Physical Review Letters), and calculations done by Scafetta & West (in the journals Geophysical Research Letters, Journal of Geophysical Research, and Physics Today) have inspired the idea that the recent warming is due to changes in the sun, rather than greenhouse gases.

We have discussed these papers before here on RealClimate (here, here, and here), and I think it’s fair to say that these studies have been fairly influential one way or the other. But has anybody ever seen the details of the methods used, or the data? I believe that a full disclosure of their codes and data would really boost the confidence in their work, if they were sound. So if they believe so strongly that their work is solid, why not more transparency?

Climate Services

Filed under: — rasmus @ 9 September 2009

I recently attended the World Climate Conference-3 (WCC-3), hosted by the World Meteorological Organization (WMO) in Geneva. Most of the talk was of providing “climate services” (CS) and coordinating these globally. But what are climate services, and how much of what was envisaged is scientifically doable?

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.

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.

Adapting in Amsterdam

Filed under: — rasmus @ 9 October 2008

EMS/ECAC 2008 venue The theme of this year’s annual meeting of the European Meteorological Society (EMS) [European Congress on Applied Climatology (ECAC)] was adaptation to climate change. So what’s more appropriate then, than hosting the meeting in Amsterdam – on a building site?
