Global warming convert's natural-gas sales push
Professor Richard Muller's U-turn on global warming made headlines, but was it a publicity stunt to push natural gas?
When you attend a lecture by an eminent scientist, a fellow of the American Society of Arts and Sciences, a recipient of the MacArthur Prize (aka the "genius grant"), among numerous other awards, you have high expectations of scientific rigour and intellectual integrity. The lecture, titled "A New Study of Global Warming: Back to 1753", was delivered at the University of Hong Kong on Monday by Professor Richard Muller, of the University of California, Berkeley.
Muller, a renowned climate-change sceptic, drew attention recently by proclaiming that, after intensive research, he had "converted" to the conclusion global warming is real - and human activity is the cause.
I came away from his lecture, however, convinced the professor is a natural-gas salesman wearing a "converted sceptic" costume.
Muller described his Berkeley Earth project, which found the rise in the earth's land temperature over the past 250 years was caused by humans, but made no mention of the impact of this global temperature rise. Acknowledging that global warming is dangerous, without giving examples, he spent more time attacking so-called exaggerated claims about the negative impact of global warming. Without going into the consequences of global warming, Muller then segued into an energy policy.
