Lamb’s Skepticism: Cleansing the Memory—Before the Warming Boom
Naturam expellas furca, tamen usque recurret.
Even during his life, the research findings and opinions of Hubert Lamb had a strangely distorted and selective influence on the climate change debate. Previously we saw how his reconstructions of regional climate variation across the last millennium have been misused in official reports as though they might indicate the global temperature anomaly. This began in 1975 when a derivative chart of winter severity for the region of Moscow served this purpose in an influential US report. This graph was subsequently re-used many times through the 1980s to indicate the global trend. Then, in 1990, the IPCC used a very different looking graph—Lamb’s extension of Gordon Manley’s central England temperature chart—which became an idol for skeptics.
In the next two posts we stay with Lamb and consider something that has remained obscure since he died in 1997, namely, his skepticism of man-made climate change. To accompany these essays, a new page is being developed as a SourceBook of Lamb’s skepticism. There you will find for the first time on the internet extensive quotation from Lamb on this topic. Our second post also contains lots of new material where it touches on aspects of Lamb’s professional biography that are not widely known, including his struggle to fund historical research into natural climatic change before the warming scare began. But firstly, below, we begin by exploring why the views of Lamb provided here might appear surprising and in contradiction to other internet sources. What becomes evident is that Lamb’s protestations against the greenhouse warming scare present difficulties for those promoting climate alarm, especially at the Climatic Research Unit (CRU), which he founded in 1972.
Part 1: Cleansing the Collective Memory
The Wikipedia enter for Hubert Lamb tells of how he was once known as ‘the ice man.’ This claim appeared in a curious addition to the first small ‘stub’ entry on the founder of the University of East Anglia’s Climatic Research Unit. We are told that our ‘ice man’ gained his epithet because he predicted global cooling and the return of the ice age. But the main point of the inserted sentence is his redemption from this view.
He was originally known as the ‘ice man’ for his prediction of global cooling and a coming ice age but, following the UK’s exceptionally hot summer of 1976, he switched to predicting a more imminent global warming.
Now, given that by 1976 the scientific controversy remained wallowing in equivocation about whether the human influence was warming or cooling [see Matthews Nov76, Peterson Sept08], and given that greenhouse warming alarm only got traction in the late 1980s, this ice-man-redemption passage in the Wikipedia entry suggests that Lamb was a harbinger of warming alarm. He was nothing of the sort.
