Climate sensitivity
Lindzen hypothesized that the Earth may act like an infrared iris. A sea surface temperature increase in the tropics would result in reduced cirrus clouds and thus more infrared radiation leakage from Earth's atmosphere.[9] Additionally, rising temperatures would cause more extensive drying due to increased areas of atmospheric subsidence. This hypothesis suggests a negative feedback which would counter the effects of CO2 warming by lowering the climate sensitivity. Satellite data from CERES has led researchers investigating Lindzen's theory to conclude that the Iris effect would instead warm the atmosphere.[46][47] Lindzen disputed this, claiming that the negative feedback from high-level clouds was still larger than the weak positive feedback estimated by Lin et al.[48]
Lindzen has expressed his concern over the validity of computer models used to predict future climate change. Lindzen said that predicted warming may be overestimated because of their handling of the climate system's water vapor feedback. The feedback due to water vapor is a major factor in determining how much warming would be expected to occur with increased atmospheric concentrations of carbon dioxide, and all existing computer models assume positive feedback — that is, that as the climate warms, the amount of water vapour held in the atmosphere will increase, leading to further warming. By contrast, Lindzen believes that temperature increases will actually cause more extensive drying due to increased areas of atmospheric subsidence as a result of the Iris effect, nullifying future warming.[3] This claim was criticized by climatologist Gavin Schmidt, Director of NASA's Goddard Institute for Space Studies, who notes the more generally-accepted understanding of the effects of the Iris effect and cites empirical cases where large and relatively rapid changes in the climate such as El Niño events, the Ultra-Plinian eruption of Mount Pinatubo in 1991, and recent trends in global temperature and water vapor levels to show that, as predicted in the generally-accepted view, water vapor increases as the temperature increases, and decreases as temperatures decrease.[49]
Contrary to the IPCC's assessment, Lindzen said that climate models are inadequate. Despite accepted errors in their models, e.g., treatment of clouds, modelers still thought their climate predictions were valid.[50] Lindzen has stated that due to the non-linear effects of carbon dioxide in the atmosphere, CO2 levels are now around 30% higher than pre-industrial levels but temperatures have responded by about 75% 0.6 °C (1.08 °F) of the expected value for a doubling of CO2. The IPCC (2007) estimates that the expected rise in temperature due to a doubling of CO2 to be about 3 °C (5.4 °F), ± 1.5°. Lindzen has given estimates of the Earth's climate sensitivity to be 0.5 °C based on ERBE data.[51] These estimates were criticized by Kevin E. Trenberth and others,[52] and Lindzen accepted that his paper included "some stupid mistakes". When interviewed, he said "It was just embarrassing", and added that "The technical details of satellite measurements are really sort of grotesque." Lindzen and Choi revised their paper and submitted it to PNAS.[53] The four reviewers of the paper, two of whom had been selected by Lindzen, strongly criticized the paper and PNAS rejected it for publication.[54] Lindzen and Choi then succeeded in getting a little known Korean journal to publish it as a 2011 paper.[53][55] Andrew Dessler published a paper which found errors in Lindzen and Choi 2011, and concluded that the observations it had presented "are not in fundamental disagreement with mainstream climate models, nor do they provide evidence that clouds are causing climate change. Suggestions that significant revisions to mainstream climate science are required are therefore not supported."[56]

Does skepticism about computer models sound unreasonable?
