The hockey stick takes another beating...
I bet this is ignored in the mainstream press...
Over the past month, one of the IPCC’s top climate scientists, Mojib Latif, attempted to explain that even if global temperatures were to cool over the next 10 to 20 years, that would not mean that man-made global warming is no longer catastrophic. It was a tough case to make, and it is not clear Mr. Latif succeeded. In a presentation to a world climate conference in early September, Mr. Latif rambled somewhat and veered off into inscrutable language that is now embedded in a million blog posts attempting to prove one thing or another.
A sample: “It may well happen that you enter a decade, or maybe even two, you know, when the temperature cools, all right, relative to the present level...And then, you know, I know what’s going to happen. You know, I will get, you know, millions of phone calls, you know —‘What’s going on?’ ‘So is global warming disappearing, you know?’ ‘Have you lied on us, you know?’ So, and, therefore, this is the reason why we need to address this decadal prediction issue.”
The decadal prediction issue appears to be a combination of computer model problems, the unpredictability of natural climate variation, and assorted uncertainties. Making all this clear to the average global citizen will not be easy and climate scientists need to be able to make it clear, said Mr. Latif. “We have to ask the nasty questions ourselves, all right, or some other people will do it.”
All this is still swirling around the global climate issue today. But now along comes another problem. Canadian data buster Steve McIntyre has spend most of the last three years deconstructing the IPCC’s famous claim that the last couple of decades of the 20th century were the hottest in a thousand years. Using what was called The Hockey Stick graph, the IPCC claimed to have the smoking gun that showed a sharp run up in global temperatures through to 1997. The validity of the IPCC data began to crumble when Mr. McIntyre and Ross McKitrick of Guelph University found serious data problems that raised doubts about the graph and the claims of record high temperatures.
As Ross McKitrick explains in his op-ed, Steve McIntyre has uncovered another data distortion that further undermines the original graphic claim that the world has set temperature records in recent years. If world temperatures may have been just as hot in the past as they have been recently, and if the the next two decades could be cooler than they have been recently, the theory of climate change becomes an even tougher case to make.
