Time to revisit events at crank central. In the course of researching the NIPCC (at the behest of Peter Dunne), I popped over to the International Climate Science Coalition site, and then on to their Australian spin-off. The Aussie crank collective is greatly enriched by the presence of Prof Bob Carter, known here as “the great communicator” because of his accomplished presentation skills and ability to make outrageous nonsense sound almost plausible. The ACSC points to Prof Bob’s latest article for Aussie magazine Quadrant, and so — noting that one R M Carter is due to give evidence to the ETS Review committee at some point — I thought I ought to catch up on the great man’s current thinking. Prepare yourself for a jaw/desk interface event:
Get this. First, there has been no recent global warming in the common meaning of the term, for world average temperature has cooled for the last ten years. Furthermore, since 1940 the earth has warmed for nineteen years and cooled for forty-nine, the overall result being that global average temperature is now about the same as it was in 1940.
Global average temperature is now “about the same” as it was 69 years ago? Obviously, the “cooling since 1998” lie no longer cuts the mustard. Bob has to bend the facts beyond breaking point to bolster his case. Here’s the NASA GISS graph:
And here’s the Hadley Centre version:
It is quite clear that global temperature is only “about the same as 1940” for definitions of “about the same” that consider variations ±0.5ºC to be inconsequential. You might as well say that because the world hasn’t warmed by 10ºC then it hasn’t warmed at all. But if you do that, then you can’t also insist that the world has cooled since 1998…
And how on Earth (or off it), did Research Professor Robert Carter of the James Cook University (Queensland) and the University of Adelaide work out that the world has warmed for 19 years but cooled for 49 since 1940? He must have a sophisticated statistical analysis to bring to bear on the topic. Or perhaps he has been counting all the little ups and downs in the GISS graph… Great science, by a great… something or other.
