Hoodwinked by Berkeley Earth


Climate Change – Notes and Comments

Propaganda Tito style

My previous post was too polite about Berkeley Earth. I’d not figured out Richard Muller’s game. The mainstream media have have portrayed him as a repentant climate sceptic who has wonderful new evidence confirming man-made global warming. To see how the story is playing, look for Richard Muller Berkeley on Google News (139 reports and counting).

Normally I try to stick to the science, without being naïve about the politics. Posted earlier on this blog is the text of a talk I gave called “Global Warming is Just Propaganda”, which you’ll find here https://calderup.wordpress.com/2010/06/07/tradecraft-of-propaganda/



It compares the behaviour of the warmists with the tradecraft of propaganda during the Second World War. And the latest bout from Berkeley and the media reminds me, belatedly, of a manipulation of British propaganda in the Balkans in the early 1940s. For global warming read Stalinism and (at the risk of grossly overstating his importance) for Richard Muller read Tito.

Hoodwinking Churchill: Tito’s Great Confidence Trick, by the TV producer and military historian Peter Batty, was published earlier this year. Helped by a Communist mole filtering messages in the British team in Cairo, Tito fooled the West into thinking that he was the hero of the fight against the Italian and German forces in Yugoslavia. In fact he was subverting other guerrilla bands, doing deals with the Germans, and keeping his forces safe for a postwar Communist takeover of Yugoslavia. As Batty relates, Tito secured his 35-year dictatorship by butchering the non-Communist guerrillas who had been the real fighters in the occupied Balkans.

When Richard Muller, leader of the Berkeley Earth Surface Temperatures (BEST) project, gave testimony to the US Congress back in March, he called for the creation of an ARPA-like agency for climate issues. ARPA, more correctly nowadays called DARPA, is the Defense Advanced Research Projects Agency, a mighty organization with a $3 billion budget. Climate ARPA (CARPA?) might offer a promising niche for a 67-year-old astrophysicist.

But if that’s the aim, catastrophic man-made global warming must stay high on the political agenda. How better to go about making sure about that than to call yourself a sceptic, just as Tito pretended to be on Winston Churchill’s side. When the time came to show himself in his true colours Tito was celebrated in the Communist world. Similarly Muller has become an instant hero for the warmists.

Scientifically grotesque was the blurring in the Berkeley press release, as well as in the media, of the meaning of Muller’s main graph, shown in my previous post. Invited to comment by New Scientist, I said:

What do they mean by ‘global warming is real’? The graph of global land temperature changes associated with BEST’s announcement neatly confirms by their independent method that the warming stopped about 15 years ago. The Sun’s recent laziness has apparently cancelled any effect of ever-increasing man-made greenhouse gases.”

The interviewer commented:

I take your point about the reduced warming trend over the last 15 years, but this study is focused on the long-term warming trend which covers a century. How do you account for this long-term warming trend?”

My reply (which wasn’t reported by New Scientist) was:

Increased activity of the Sun, of course, from 1950 to the early 1990s as signalled most strikingly by the decline in ionizing cosmic rays at the Earth’s surface. See the red curve (ion chamber) in the attached figure.”

This is a coloured version of a graph in Henrik Svensmark, Physical Review Letters, 81, 5027-30,1998.

The message about Muller in the media, that “the science is settled (again)”, is completely at odds with the evidence.

The long pause in warming confirmed


Climate Change – News and Comments

Nice research, curious rhetoric

Just dis-embargoed at noon PST (8 pm BST) on 20 October are a press release and associated papers from the Berkeley Earth Surface Temperatures (BEST) project. A team led by Richard A. Muller has been asking whether the histories of land surface temperatures from the likes of NOAA, NASA and the Hadley Centre are to be trusted. Clever statistics glean and process raw data from 39,000 weather stations world wide – more than five times as many as used by other analysts.

The short answer is that the other histories are broadly validated, as seen in this graph from one of the new papers.

If your eye can trace the black line of the BEST study, based on a random selection of weather stations, you’ll see that the average temperatures of the land correspond quite well with the other series.

What’s very odd is the rhetoric of the press release. It begins:

Global warming is real, according to a major study released today. Despite issues raised by climate change skeptics, the Berkeley Earth Surface Temperature study finds reliable evidence of a rise in the average world land temperature of approximately 1°C since the mid-1950s.

Global warming real? Not recently, folks. The black curve in the graph confirms what experts have known for years, that warming stopped in the mid-1990s, when the Sun was switching from a manic to a depressive phase.

Elsewhere the press release first begs the question by calling the past 50 years “the period during which the human effect on temperatures is discernible” and then contradicts this by saying, What Berkeley Earth has not done is make an independent assessment of how much of the observed warming is due to human actions, Richard Muller acknowledged.”

Let me say there is interesting stuff in the material released today, particularly in the paper on Decadal Variations, tracing links with El Niño and other regional temperature oscillations” — a subject I may return to when I have more time.

It hasn’t escaped my attention that BEST is today gunning mainly for Anthony Watts and his Surface Stations project in the USA, but he’s well capable of answering for himself. See wattsupwiththat.com/2011/10/20/the-berkeley-earth-surface-temperature-project-puts-pr-before-peer-review/

Added 21 October: See this rather uneasy comment from Judith Curry, a member of the Berkeley teamhttp://judithcurry.com/2011/10/20/berkeley-surface-temperatures-released/

And later: New Scientist quotes me saying something similar to what’s above – followed of course by the usual grossly biased and poorly informed attempt at a put-down http://www.newscientist.com/article/dn21074-sceptical-climate-scientists-concede-earth-has-warmed.html
