Yup, CO2’s going up and the models say the temperature should be going up too – but the temperature isn’t going up. So why is that?
I would expect that most people who are seriously interested in global warming know the IPCC models incorporate positive feedback factors. These feedback factors multiply the effect of CO2’s warming by several times.
A recent paper accepted by the Asia Pacific Journal of Atmospheric Sciences, by Lindzen (MIT, USA) and Choi (EWU, Korea), May 2011, ‘On the observational determination of climate sensitivity and its implications’ investigates the topic by comparing changes in satellite measured outgoing radiation with changes in sea surface temperatures. The paper updates their earlier work published in 2009. The last few sentences from their May 2011 abstract states
‘We find again that the outgoing radiation resulting from SST [sea surface temperature] fluctuations exceeds the zero feedback response thus implying negative feedback. In contrast to this, the calculated TOA [top of atmosphere] outgoing radiation fluxes from 11 [IPCC] atmospheric models forced by the SST are less than the zero feedback response, consistent with the positive feedbacks that characterise these models. The results imply that the models are exaggerating climate sensitivity.’
