- Climate Models, Clouds, OLR, and ECS Wed, 18 Dec 24, 5:00amBy Andy May The IPCC and the climate “consensus” believe that essentially all warming since 1750 is due to man’s emissions of CO2 and other greenhouse gases as shown in…
- The Quest for Climate’s “Golden Fleece” Sun, 18 Aug 24, 11:00pmHowever, since actual temperature and CO2 data result in a current climate sensitivity of ca. 1.25, there is plainly something wrong with the current “fad” for climate sensitivities of 3 or more.
- Green on Green: Wilderness Protection Laws and Indigenous Rights are Derailing Renewable Energy Projects Wed, 24 Apr 24, 7:00amLaws protecting Koalas and "the magnificent brood frog" have prevented a renewable energy company from clearing 500 acres of native vegetation in the Australian tropics.
- Two model-observation comparisons confirm: CMIP6 models run too hot Sat, 3 Feb 24, 7:40amBy Frank Bosse and Nic Lewis A recent article by Roy Spencer was (strongly) criticized by Gavin Schmidt over at “Real Climate”. In the summary Gavin S. wrote: “Spencer’s shenanigans are designed to mislead readers...
- Long Term Climate Sensitivity After All Feedback Has Acted Mon, 29 Jan 24, 9:00pmThe problems encountered by scientists trying to put a number on Equilibrium Climate Sensitivity (ECS) for CO2x2 are almost insurmountable because of this complexity and estimates, consequently, vary greatly.
- New Journal of Climate Study Reduces Doubled CO2 Climate Sensitivity By 40%, To 0.72°C Wed, 24 Jan 24, 9:00pmFrom the NoTricksZone By Kenneth Richard Doubling the 2005 CO2 concentration (380 ppm) to 760 ppm only produces a globally-averaged 2.26 W/m² perturbation at the top of the atmosphere (TOA). This…
- A Thought Experiment; Simplifying the Climate Riddle. Thu, 21 Dec 23, 5:00pmIs it possible to simplify the climate sensitivity debate?
- Hansen’s latest overheated global warming claims are based on poor science Fri, 10 Nov 23, 1:00am...he leads are increasingly strongly biased towards overheated projections and dire conclusions.
- Hansen’s latest overheated global warming claims are based on poor science Tue, 7 Nov 23, 6:58amJames Hansen’s latest paper “Global warming in the pipeline” (Hansen et al. (2023)) has already been heavily criticized in a lengthy comment by Michael Mann, author of the original IPCC ‘hockey stick’....
- Spencer and Christy’s new climate sensitivity paper has been published – and its LOWER. Sat, 30 Sep 23, 3:10amFrom Dr. Roy Spencer: If we assume ALL *observed* warming of the deep oceans and land since 1970 has been due to humans, we get an effective climate sensitivity to…
- An Unsettling Insight Fri, 29 Sep 23, 3:00amGuest Post by Willis Eschenbach I got to thinking about the classical way to measure the very poorly-named “greenhouse effect”, which has nothing to do with greenhouses...
- More on the statistical dispute between Scafetta and Schmidt Sun, 24 Sep 23, 3:00amBy Andy May The argument about the proper way to estimate error in the European Centre for Medium-Range Weather Forecast (ECMWF) ERA5 weather reanalysis dataset between Nicola Scafetta and Gavin…
- Do CMIP5 models skillfully match actual warming? Wed, 6 Sep 23, 2:36amWhy matching of CMIP5 model-simulated to observed warming does not indicate model skill A well-known Dutch journalist, Maarten Keulemans of De Volkskrant, recently tweeted an open letter to the Nobel-prizewinning physicist...
- How Much Warming Can We Expect in the 21st Century? Sun, 9 Jul 23, 11:00pmAssuming that the climate sensitivity from Lewis22 is correct and that RCP3.4 is the most appropriate emissions scenario, then we find that global temperatures will rise by less than 1°C from 2023 to 2100 (not accounting...
- The Elephants in The Room Thu, 4 May 23, 7:00pmOn that assumption, each $1 billion spent on abatement would prevent less than 1/10,000,000 C:
