On the Reproducibility of the IPCC’s climate sensitivity

I wonder what @RHarrabin of the BBC will make of this?

“The conclusion is that the IPCC’s warming values are about 200 % too high (1.75 degrees versus 0.6 degrees) because both the CO2 radiative forcing equation, and the CS calculation include water feedback.”

Watts Up With That?

Guest essay by Dr. Antero Ollila

The highest ranked scientific journal Nature published on the 28th of July 2016 an article based on the survey for 1,576 researchers. More than 70 % of the researchers were not able to reproduce the results of another scientist’s experiments. Are there any attempts to reproduce IPCC’s climate sensitivity?

I think that the most important key figure of the climate change science is the value of the climate sensitivity (CS), because it describes the warming effects of the major greenhouse gas carbon dioxide (CO2). CS means the temperature increase corresponding to the doubling of CO2 concentration of 280 ppm.

1. IPCC’s estimates of climate sensitivity

IPCC still uses a very simple equation in calculating the global mean surface temperature response dTs (AR5, p. 664)

dTs = CSP* RF (1)

where CSP (also marked by lambda) is the Climate Sensitivity Parameter (K/(W/m2)) and RF…

GWPF Condemns Misleading Committee on Climate Change Report on Policy Costs


By Paul Homewood



The GWPF has also responded quickly and emphatically to the Committee on Climate Change’s grossly misleading report on the cost of climate policy:

Today’s statement on Energy Prices and Bills by Lord Deben’s Committee on Climate Change confirms growing suspicions that it is neither objective nor reliable as an advisor to the public about the true cost of climate policies.

The CCC’s attempt to reassure the public about the cost impact of climate policies is a misleading whitewash. Contrary to the spin of the CCC, their own figures show that almost all the projected increase in domestic electricity prices between 2016 and 2030 is the result of energy and climate policies.

According to the CCC’s own work (see chart 1.7) energy and climate policies have increased prices to domestic consumers by 33% in 2016. In other words they are 33% higher at present than they would…

What is the Opportunity Cost of Climate Waste?

Makes you think.

Ending world poverty sounds like something even the contemptible Greenpeace would applaud?

I won’t hold my breath.

Watts Up With That?

What do we miss out on because the world wastes so much money and attention on climate? Imagine if some of that squandered money was spent on other fields such as medical research, such as the following accidental discovery, which if developed offers the possibility of longer life and superhuman athletic prowess.

Born to run; the story of the PEPCK-Cmus mouse

Richard W. Hanson and Parvin Hakimi

In order to study the role of the cytosolic form of phosphoenolpyruvate carboxykinase (GTP) (EC (PEPCK-C) in skeletal muscle, PEPCK-Cmus mice were created by introducing the cDNA for the enzyme, linked to the human α-skeletal actin gene promoter, into their germ line. Two founder lines generated by this procedure were bred together, creating a line of mice that have 9.0 units/g…
