The Skeptic’s Case Who Are You Going To Believe – The Government Climate Scientists Or The Data? Guest Post Dr David M.W. Evans

We check the main predictions of the climate models against the best and latest data. Fortunately the climate models got all their major predictions wrong. Why? Every serious skeptical scientist has been consistently saying essentially the same thing for over 20 years, yet most people have never heard the message — here it is, put simply enough for any lay reader willing to pay attention.

What the Government Climate Scientists Say

 

Figure 1: The climate models. If the CO2 level doubles (as it is on course to do by about 2070 to 2100), the climate models estimate the temperature increase due to that extra CO2 will be about 1.1°C × 3 = 3.3°C. [1]

The direct effect of CO2 is well-established physics, based on laboratory results, and known for over a century.[2]

Feedbacks are due to the ways the Earth reacts to the direct warming effect of the CO2. The threefold amplification by feedbacks is based on the […]

A case against precipitous climate action

UPDATED (see below)

Richard Lindzen is unarguably one of the top meteorologists in the world, with over 200 publications to his name, as well as awards, medals, prizes and is a member of the NAS, AAAS, AGU, AMS. He is The Alfred P. Sloan Professor of Atmospheric Sciences, Massachusetts Institute of Technology and his work includes major contributions to our understanding of the Hadley Circulation, small scale gravity waves on the mesosphere, as well as atmospheric tides and oscillations in the tropical stratosphere. From the beginning, he has questioned the claims that there is a crisis due to carbon dioxide emissions, pointing out that even with the poor resolution of ice cores back in the 1980’s it was still evident that there was a lag—as temperatures declined, carbon stayed high for thousands of years, something which didn’t sit well with the idea that carbon had a strong and constant force on the climate.

What follows are his thoughts on the current state of the science. They must make it awkward for those who can’t help themselves but believe in authority. Here’s a man who knows more than most of us could ever hope […]
