Corrected RCP Scenario Removal Fractions

Reposted from Dr. Roy Spencer’s blog February 6th, 2020 by Roy W. Spencer, Ph. D. Well, as I suspected (and warned everyone) in my blog post yesterday, a portion of my calculations were in error regarding how much CO2 is taken out of the atmosphere in the global carbon cycle models used for the RCP…

One Upside of More CO2: Beautiful Upper Atmospheric Clouds

Reposted from Dr. Roy Spencer’s Blog January 1st, 2020 by Roy W. Spencer, Ph. D. Polar Stratospheric Cloud display (smartphone photo posted by Reddit user Breuuan on Dec. 31, 2019.) Increasing carbon dioxide in the atmosphere will continue to cause upper atmospheric cooling in the 2020s, which will lead to some of the most beautiful…

Earth As A Solar Collector

Guest post by Kevin Kilty Introduction Within the past week or two we have read posts from Dr. Spencer (6/7/2019), Nick Stokes (6/6/2019), Lord Monckton (6/8/2019), and Willis Eschenbach (6/8/2019) covering a variety of topics involving simple block models; and each one involving, in one way or another, climate feedback. I have had a few…

Electric-blue night clouds are invading the U.S.

Reposted from Dr. Roy Spencer’s Blog I have personally cussed out Dr. Spencer for adding an item to my bucket list which had been almost complete.~ctm June 11th, 2019 by Roy W. Spencer, Ph. D.

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…
