The Mysterious AR6 ECS, Part 1
By Andy May Christian Freuer has translated this post to German here. The climate sensitivity to CO2 and other greenhouse gases (GHGs) is arguably the most important number in the…
The error of the mean: a dispute between Gavin Schmidt and Nicola Scafetta
By Andy May You can read this post in German here, courtesy of Christian Freuer. Here we go again, writing on the proper use of statistics in climate science. Traditionally,…
Sunshine and Temperature in Holland
Guest Post by Willis Eschenbach Well, the endless curiosity of my monkey-mind led me to some interesting datasets over at KNMI. They’re a variety of meteorological measurements made in Holland…
Equilibrium Doubled-CO2 Sensitivity by Observational Methods
On that basis, each $1 billion that Britain and the world spends on chasing after net zero will prevent just one thirty-millionth of a degree of warming that would otherwise…
Climate Sensitivity from 1970-2021 Warming Estimates
.. the observational data suggest lower climate sensitivities (ECS) than promoted by the IPCC with a central estimate of +2.09 deg C. for the global average. This is at the…
Transient Climate Response from Observations 1979-2022
The best estimate of TCR based on CMIP6 models (the red line in Fig.1) is 1.6K / 2*CO2, following the cited paper.
Scatterplot Sensitivity
Guest Post by Willis Eschenbach This is the third post looking at the use of 1° latitude by 1° longitude gridcell-based scatterplots. The first post, Global Scatterplots, looked at a…
Solar Sensitivity
Once the average available solar power is above 310W/m2, you can add up to an additional 50 W/m2 without increasing the surface temperature one bit.
Important New Paper Challenges IPCC’s Claims about Climate Sensitivity
Official IPCC estimates of future global warming may be overstated
A More Accurate Multiplier
Guest Post by Willis Eschenbach In my previous posts, yclept “Greenhouse Efficiency” and “The Multiplier”, I described a metric I’d developed to look at how successful the very poorly named…
A Serious Question
Guest Post by Willis Eschenbach Apparently I must be a glutton for punishment, because here I am in the arena once again, discussing the results of my research and preparing…
The Multiplier
Guest Post by Willis Eschenbach This is a follow-on from my previous post entitled Greenhouse Equilibrium. If you haven’t read it, you might want to, as it introduces many of…
Greenhouse Efficiency
Guest Post by Willis Eschenbach Buoyed by equal parts of derision and praise for my last post, “Surface Radiation: Absorption And Emission“, I once again venture into the arena. I…
Surface Radiation: Absorption And Emission
Guest Post by Willis Eschenbach In my recent post “Putting It Into Reverse” I discussed the relationship between temperature and total surface radiation absorbed. By “total surface radiation absorbed”, I…
Outside The Black Box
Models that need model-specific input to replicate the known past, violate the most basic criteria of science to earn the label “scientifically proven”, independent of the “proven physics” they are…
Restoring The Equilibrium
Guest Post by Willis Eschenbach In this post, I will both provide additional data for and also correct an error and a claim in my post entitled Where Is The…
Into The Black Box
Guest Post by Willis Eschenbach Through what in my life is a typical series of misunderstandings and coincidences, I ended up looking at the average model results from the Climate…
Nearly 140 Scientific Papers Detail The Minuscule Effect CO2 Has On Earth’s Temperature
As of 2016 this list had only 50 papers on it (as indicated by the web address). In less than 6 years the list has grown to 137 (as of…
