"Their excuse for the absence of warming over the past 17 years is that the heat is hiding in the deep ocean. 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. Thus, they now, somewhat obscurely, admit that their crucial assumption was totally unjustified.
Finally, in attributing warming to man, they fail to point out that the warming has been small, and totally consistent with there being nothing to be alarmed about. It is quite amazing to see the contortions the IPCC has to go through in order to keep the international climate agenda going."
