Vox Day points to two articles that raise fundamental doubts about the accuracy of the IPCC’s report, which claims – with 95% certainty!!!! – that human activity is the main driver behind rising temperatures.
For one thing, the report kinda sorta didn’t really explain why the Earth hasn’t warmed over the past 15 years:
“Their excuse for the absence of warming over the past 17 years is that the heat is hiding in the deep ocean,” [MIT Professor Richard] Lindzen added. “However, this is simply an admission that the models fail to simulate the exchanges of heat between the surface layers and the deeper oceans.”
“However, it is this heat transport that plays a major role in natural internal variability of climate, and the IPCC assertions that observed warming can be attributed to man depend crucially on their assertion that these models accurately simulate natural internal variability,” Lindzen continued. “Thus, they now, somewhat obscurely, admit that their crucial assumption was totally unjustified.” [Emphasis added.]
To Lindzen, this indirect admission by the IPCC makes the manufactured alarmism resulting from the report “laughable.”
Nigel Lawson, Chairman of the Global Warming Policy Foundation, lays out the basis for what the report really is:
The true scientific method is founded on empirical observation. When a theory – whether embedded in a computer program or not – produces predictions that are falsified by subsequent observation, then the theory, and the computer models which enshrine it, have to be rethought.
Not for the IPCC, however, which has sought to obscure this fundamental issue by claiming that, whereas in 2007 it was 90 per cent sure that most of the (very slight) global warming recorded since the Fifties was due to man-made carbon emissions, it is now 95 per cent sure.
This is not science: it is mumbo-jumbo. Neither the 90 per cent nor the 95 per cent have any objective scientific basis: they are simply numbers plucked from the air for the benefit of credulous politicians and journalists. [Emphasis added.]
