Guest essay by Dr. Ira Glickstein We’ve reached a turning point where it is hard for any Global Warming Alarmist to claim (with a straight face) that the world as…

Climate Craziness of the Week: only the 'cooler' models are wrong – the rest say 4ºC of warming by 2100
From the University of New South Wales and Dr. Steven Sherwood: “Climate sceptics like to criticise climate models for getting things wrong, and we are the first to admit they…
The Fatal Lure of Assumed Linearity
Guest Post by Willis Eschenbach [note new Update at the end, and new Figs. 4-6] In climate science, linearity is the order of the day. The global climate models are…
Mechanical Models
Guest Post by Willis Eschenbach [NOTE the update at the end of the post.] I’ve continued my peregrinations following the spoor of the global climate model data cited in my…
Study: lack of cloud physics biased climate models high
The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for…
The 'worse than we thought' model
From ETH Zurich: Underestimated future climate change? 25.11.2013 | Fabio Bergamin New model calculations by ETH researcher Thomas Frölicher show that global warming may continue after a stoppage of CO…
New study: '…climate system is only about half as sensitive to increasing CO2 as previously believed'
Warming since 1950s partly caused by El Niño HUNTSVILLE, Ala. (Nov. 11, 2013) – A natural shift to stronger warm El Niño events in the Pacific Ocean might be responsible…
A Sea Change for Climate Science?
By David Stockwell writing in Quadrant Online As CO2 climate models falter and even the IPCC backs off its estimates, it just may be that a radical shift in thinking…
Chylek et al 2013 shows a linkage between US Southwest climate and AMO/PDO cycles
This paper suggests that the CMIP5 models’ (which IPCC relies upon) predicted US SW temperature sensitivity to the GHG has been significantly overestimated by about a factor of two. Imprint…
The Cloud Radiative Effect, Take Two
Guest Post by Willis Eschenbach Well, in my last post I took a first cut at figuring the cloud radiative “feedback” from the CERES dataset. However, an alert commenter pointed…
The Cloud Radiative Effect (CRE)
Guest Post by Willis Eschenbach [UPDATE: An alert commenter, Ken Gregory, has pointed out that in addition to the temperature affecting the CRE, it is also affected by the changing…
Dr. Kiehl's Paradox
Guest Post by Willis Eschenbach Back in 2007, in a paper published in GRL entitled “Twentieth century climate model response and climate sensitivity” Jeffrey Kiehl noted a curious paradox. All…
50:1 should now be 100:1
Low ECS doubles the cost:benefit shortfall Guest essay by Barry Brill Topher Fields’ excellent documentary video http://topher.com.au/50-to-1-video-project/ explains that the overall costs of any global effort to reduce greenhouse gas…
One Step Forward, Two Steps Back
Guest Post by Willis Eschenbach David Rose has posted this , from the unreleased IPCC Fifth Assessment Report (AR5): ‘ECS is likely in the range 1.5C to 4.5C… The lower…
BREAKING: IPCC AR5 report to dial back climate sensitivity
Update: the IPCC edifice is crumbling, see The state of climate science: ‘fluxed up’ See also Willis’ article One Step Forward, Two Steps Back, and Lomborg: climate models are running way too hot…
More low climate sensitivity
This paper A lower and more constrained estimate of climate sensitivity using updated observations and detailed radiative forcing time series from Skeie et al is now in open peer review…
A low-sensitivity climate model that outperforms the Met Office's HADGEM2
Climate sensitivity is IMHO, the most important unresolved issue in climate science. A number of recent papers, including the IPCC AR5 leak, plus the recent Economist leak of a later…
Newsbytes: The Economist Reveals Sensitive IPCC Information
IPCC Draft Lowers Global Warming Projections on Climate Sensitivity “That report is going to scare the wits out of everyone,” said Yvo de Boer recently. He is a former United…
The Thousand-Year Model
Guest Post By Willis Eschenbach Back in 2007, Jeffrey Kiehl first pointed out a curious puzzle about the climate models, viz: (emphasis mine) [3] A review of the published literature…
