Climate Models: New Expert Consensus Confirms That IPCC & NASA Models Significantly Overestimated Climate Sensitivity

Skeptics' views regarding catastrophic global warming have been proven correct - experts now believe that climate models have overestimated the climate sensitivity to a doubling of CO2 levels

Read here. Climate skeptics (luke warmers and others) have long contended that the supercomputer climate models used by the IPCC and NASA have significantly overestimated the potential global warming due to a doubling of atmospheric CO2 levels.

The majority of skeptics believe that any warming due to increased CO2 emissions will result in temperature increases of 2°C or less by year 2100. Recently, new peer reviewed studies by the experts have been published that reveals a new consensus being reached that confirms the skeptics' point of view: catastrophic global warming isn't in the cards.

New research on current climate models

"A collection of research results have been published in the peer-reviewed scientific literature in recent months that buoys my hopes for a low-end climate sensitivity"..."there has been substantial research into the probability distribution which contains the earth’s equilibrium climate sensitivity and the emerging bulk of evidence suggests that the IPCC’s “likely” range for the equilibrium climate sensitivity is much too large and that the possibility that the equilibrium climate sensitivity lies above 6°C is vanishingly small—if not entirely ruled out. Even the chance that it exceeds 4.5°C has been markedly reduced to being no more than about 5% (if not even less)."..."Our analysis also leads to a relatively low and tightly-constrained estimate of Transient Climate Response of 1.3–1.8°C, and relatively low projections of 21st-century warming..."For uncertainty assumptions best supported by global surface temperature data up to the present time, this paper finds a most likely present-day estimate of the transient climate sensitivity to be 1.6 K..."

Conclusion: The alarmist predictions of catastrophic global warming have been incorrectly based on the exaggerated climate sensitivity programmed into the climate models of major climate research agencies, including those that the IPCC relies on.
