Drip by Drip by Drip - The Science Becomes Unsettled

Pielke Destroys the UN's International Panel on Climate Change Theories

IPCC Claim:

“Over several decades of development, models have consistently provided a robust and unambiguous picture of significant climate warming in response to increasing greenhouse gases.”
“…models are unanimous in their prediction prediction of substantial climate warming under greenhouse gas increases

Global warming has not occurred for the last several years

IPCC Claim:
“New observational and modelling evidence strongly supports a combined water vapour-lapse rate feedback of a strength comparable to that found in General Circulation Models

The increase of water vapor content of the atmosphere has been muted at most zero over the last few years;

IPCC Claim:
The understanding of anthropogenic warming and cooling influences on climate has improved since the TAR, leading to very high confidence that the global average net effect of human activities since 1750 has been one of warming, with a radiative forcing of +1.6
“Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level”

Using the IPCC estimate of global radiative forcing and the diagnosis of the radiative imbalance from ocean heat content changes, the global radiative feedbacks are negative.
These failures of the projections (predictions) of the 2007 IPCC report, by themselves, should result in the rejection of the IPCC report as representing settled climate science.
