MP EXPOSES FLAWED IPCC SUMMARY IN UK PARLIAMENT DEBATE

Here is a link to the debate in which Peter Lilley exposed a number of serious weaknesses in the IPCC summary for policy makers. Here are a few extracts:

 "There has been a hiatus in warming, yet during that period since 1997, one third of all the carbon dioxide ever emitted by mankind has been pumped into the atmosphere. We have had 17 years to test the effect of a third of all the CO2 we have ever emitted, and there has been no increase in temperature"
"That does not seem to be evidence for being more certain; it seems to be evidence for being a little more qualified in stating that CO2 may be the dominant factor. It clearly was not dominant during that period. By definition, a period with record emissions but no warming cannot provide further evidence that emissions are the dominant cause of warming"
"For the first time, the authors of the IPCC report are unable to agree on a best estimate of how sensitive the climate is to increases in CO2. In previous reports, they have always been able to agree a best estimate, but this time, there has been so much disagreement among them that they have been unable to reach one".
"Nor does the summary mention that in the body of the report, the IPCC’s medium-term forecast for temperature increases to 2035 is below that given by the climate models. In other words, the experts used their judgment to say that in their opinion, the climate models are wrong. They came up with a forecast below the models, and they explain that the reason is that the models have been overheating"
"None of the models take into account the latest information on aerosols. Had they done so, they would have produced an even higher forecast for future warming, because the future warming forecast involves the warming created by CO2 less the cooling created by aerosols."
