New Paper–NO EXPERIMENTAL EVIDENCE FOR THE SIGNIFICANT ANTHROPOGENIC CLIMATE CHANGE

I didn’t vet this before posting and have no idea as to its real strengths or weaknesses. Have at it.~ctm From Arvix J. KAUPPINEN AND P. MALMI Abstract. In this paper we will prove that GCM-models used in IPCC report AR5 fail to calculate the influences of the low cloud cover changes on the global…

Columbia researchers provide new evidence on the reliability of climate modeling

Observational data of equatorial circulation pattern confirms that the pattern is weakening, a development with important consequences for future rainfall in the subtropics Columbia University School of Engineering and Applied Science News Release 24-Jun-2019 New York, NY–June 24, 2019–For decades, scientists studying a key climate phenomenon have been grappling with contradictory data that have threated…

MODTRAN: ITS QUIRKS AND USES.

Guest post by KEVIN KILTY An Atmospheric Transmission Model Introduction This post is not one I planned to do. It has grown from work I was doing with MODTRAN (moderate resolution transmission program) in support of my post on June 14, 2019. As I mentioned in that thread I had gotten odd results from MODTRAN,…

Earth system models underestimate carbon fixation by plants in the high latitudes

From Nature Communications. Abstract Most Earth system models agree that land will continue to store carbon due to the physiological effects of rising CO2 concentration and climatic changes favoring plant growth in temperature-limited regions. But they largely disagree on the amount of carbon uptake. The historical CO2 increase has resulted in enhanced photosynthetic carbon fixation…

Feedback is not the big enchilada

By Christopher Monckton of Brenchley I am most grateful to Mr Stokes for his interesting recent posting in which he explains what he sees as the difference between official climatology’s implementation of feedback in deriving climate sensitivity and the approach taken by my co-authors and me. The sheer quantity of the comments on these mathematical…

Latest Global Temp. Anomaly (May ’19: +0.32°C) A Simple “No Greenhouse Effect” Model of Day/Night Temperatures at Different Latitudes

Reposted from Dr. Roy Spencer’s blog June 7th, 2019 by Roy W. Spencer, Ph. D. Abstract: A simple time-dependent model of Earth surface temperatures over the 24 hr day/night cycle at different latitudes is presented. The model reaches energy equilibrium after 1.5 months no matter what temperature it is initialized at. It is shown that…

Demystifying feedback.

Guest post by Nick Stokes, People outside climate science seem drawn to feedback analogies for climate behaviour. Climate scientists sometimes make use of them too, although they are not part of GCMs. But it gets tangled. In fact, all that the feedback talk is usually doing is describing the behaviour of variables that satisfy a…

Cycles of Rapid Climate Warming

By Jim Steele Published in the Pacifca Tribune May 28, 2019 What’s Natural Cycles of Rapid Climate Warming The globally averaged temperature rose 1.5°F from 1880 to today. Various narratives suggest the rise since 1950 was driven by increasing concentrations of CO2. The rising temperature before 1950 was considered natural. Since 1990, Arctic temperatures rose…
