Bishop Hill in Climate: Cuttings

There's been plenty of excitement in climate circles this week, so without further ado, here's what you may have missed.

The Lockwood & Frohlich paper and its claim to refute the solar theory of climate change continues to attract comment.

Willson runs the NASA's ACRIM programme which collects the data on solar output. He thinks Lockwood should have used his ACRIM results rather than Frohlich's own PMOD series which represents ACRIM plus some heavily disputed "corrections".

Scafetta points out that the results of the Lockwood paper would be quite different if they had used ACRIM instead of PMOD and takes Lockwood & Frohlich to task for not considering this. He also takes issue with their averaging technique which implies that temperature at any point in time is partly driven by the future output of the sun!

There's also more comment on the Armstong paper claims of the inadequacy of climate forecasts. has now passed the 200 mark and should hit 20% of the network next week. 

The Great Global Warming Swindle was shown on Australian TV to a great deal of hoo-ha. Martin Durkin said that the film survived the mauling it received.

Roger Pielke Snr continues to post on the failure of the IPCC to address the issue of land use and its effect on climate. This post has a huge list of papers that were ignored.

Next week should see a lot of interest in a new paper from two German scientists, Gerlich & Tscheuschner. They claim to have refuted the greenhouse theory of climate change once and for all.

And lastly, this letter to the FT:

From Mr Ake Nilson.

Sir, In your editorial "It's time to plan for the next deluge" (July 25) you say that "it is now scientifically incontrovertible that global warming is making heavy rain fall more frequently across the world's temperate latitudes". But less than a year ago, on August 10 2006, you reported: "This year's hot, dry summer will be repeated many times in the future and will become normal in the next 40 to 50 years if climate scientists are correct."

Please could you make up your mind as to the effect of global warming?

Ake Nilson
