The Lewis and Crok exposition – Climate less sensitive to Carbon Dioxide than most models suggest
Full papers plus additional comments from co-author Nic Lewis follow. I have added some relevant diagrams and tables from the report, plus reproduced the foreword by Dr. Judith Curry as…
Chicken al la still not a king
The royal prince in waiting of Britain labels climate skeptics as “headless chickens”. From The Telegraph: Prince Charles has criticised climate change deniers, describing them as the “headless chicken brigade”…
CO2 and CERES
Guest Post by Willis Eschenbach The Intergovernmental Panel on Climate Change, the bureaucratic agency which appropriated the role of arbiter of things climatic, has advanced a theory for the lack…
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…
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…
Commonsense Climate Science and Forecasting after AR5
Guest Essay by Dr. Norman Page 1.The Demise of the IPCC and the CAGW Delusion. a) Overview. In the AR5 Summary for Policymakers the IPCC glossed over the developing cooling trend…
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…
Friday Funny – Katharine Hayhoe: only YOU can control the climate!
@bkparallax @IamDonCheadle the power to change climate lies in hands of every individual on the planet, not a single gov't–or technology! — Prof. Katharine Hayhoe (@KHayhoe) August 29, 2013 With…
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…
The IPCC has a real pack of trouble on its hands
By Paul C. “Chip” Knappenberger and Patrick J. Michaels The United Nations Intergovernmental Panel on Climate Change (IPCC) is in the midst of finishing its Fifth Assessment Report (AR5) on…
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…
Climate Sensitivity Deconstructed
Guest Post by Willis Eschenbach I haven’t commented much on my most recents posts, because of the usual reasons: a day job, and the unending lure of doing more research,…
Australian scientists take 6 degrees of global warming off the table, say it is closer to 2 degrees
From the University of Melbourne Scientists narrow global warming range Australian scientists have narrowed the predicted range of global warming through groundbreaking new research. Scientists from the University of Melbourne and Victoria…
Updated climate sensitivity estimates using aerosol-adjusted forcings and various ocean heat uptake estimates
Guest essay by Nic Lewis The Otto et al. paper has received a great deal of attention in recent days. While the paper’s estimate of transient climate response was low,…
Model Climate Sensitivity Calculated Directly From Model Results
Guest Post by Willis Eschenbach [UPDATE: Steven Mosher pointed out that I have calculated the transient climate response (TCR) rather than the equilibrium climate sensitivity (ECS). For the last half…
