Despite what you may have heard about the death of the coal industry, Peabody Energy is ramping up mining activities and going on the offensive, pushing “clean coal” on the world’s poor with a disingenuous but aggressive PR campaign. And for good reason: Peabody has got to sell the coal from...read more

Gerhard Gerlich teaches Mathematical Physics at the Technical University Carolo-Wilhelmina (Institut für Mathematische Physik) in Braunschweig, Germany.
Gerlich co-wrote a 2007 paper titled “Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics” that has been widely cited in the skeptic community as refutation for the existence of man-made global warming.
Stance on Climate Change
“…the CO2-greenhouse effect of the earth atmosphere is pure fiction of people who like to use big computers, without physical fundamentals.” 
“The main strategy of modern CO2-greenhouse gas defenders seems to hide themselves behind more and more pseudo explanations, which are not part of the academic education or even of the physics training.”

Gerlich published a paper titled “Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics” in the International Journal of Modern Physics (IJMP).
The paper has was widely cited in the skeptic community as refutation for the existence of man-made global warming and has been mentioned by many skeptical science sites like Climate Research News and Greenie Watch.
Another article, also published by the International Journal of Modern Physics (this in 2010), thoroughly refutes the Gerlich and Tscheuschner paper. Other sources have since released refutations or responses (for example, here and here). 
Gerlich is a signatory to an open letter to Secretary-General Ban Ki-Moon which concludes that “Attempts to prevent global climate change from occurring are ultimately futile, and constitute a tragic misallocation of resources that would be better spent on humanity's real and pressing problems.” 
Spoke at the Leipzig Conference on Climate Change. His speech was titled “Die physikalischen Grundlagen des Treibhauseffektes und fiktiver Treibhauseffekte” or “The physical fundamentals of the greenhouse effect and fictitious greenhouse effects.” 
Gerlich signed the subsequent Leipzig Declaration on Climate Change. The declaration states that “there does not exist today a general scientific consensus about the importance of greenhouse warming from rising levels of carbon dioxide. In fact, most climate specialists now agree that actual observations from both weather satellites and balloon-borne radiosondes show no current warming whatsoever…”
