Insights from Karl Popper: how to open the deadlocked climate debate

Posted on January 28, 2016 by curryja | 654 comments

by Larry Kummer, from the Fabius Maximus website.

Many factors have frozen the public policy debate on climate change, but none more important than the disinterest of both sides in tests that might provide better evidence — and perhaps restart the discussion. Even worse, too little thought has been given to the criteria for validating climate science theories (aka their paradigm) and the models build upon them.

On the likelihood of recent record warmth

Posted on January 26, 2016 by curryja | 192 comments

by Judith Curry

[O]ur results suggest that the recent record temperature years are are roughly 600 to 130,000 times more likely to have occurred under conditions of anthropogenic than in its absence. – Mann et al.

Huge efficacy of land use forcing in one GISS-E2-R simulation: is an ocean model error involved?

Posted on January 25, 2016 by curryja | 137 comments

by Nic Lewis

In a recent article here, which summarised a longer piece at ClimateAudit, I discussed the December 2015 Marvel et al.[1] paper, which contends that estimates of the transient climate response (TCR) and equilibrium climate sensitivity (ECS) derived from recent observations of changes in global mean surface temperature (GMST) are biased low.

Appraising Marvel et al.: Implications of forcing efficacies for climate sensitivity estimates

Posted on January 10, 2016 by curryja | 265 comments

by Nicholas Lewis

Different agents may have effects on global temperature (GMST) different to those which would be expected simply by reference to the radiative forcing they exert. This difference is encapsulated in the term “forcing efficacy”.
