Dr. Gerhard Gerlich and Ralf D. Tscheuschner of the Institute for Mathematical Physics at the Carolo-Wilhelmina Technical University, Germany, demonstrate the falsity of the greenhouse gas theory in lengthy technical discussion. The process that greenhouse gas advocates support doesn't exist. Of particular interest is his discussion on page 31 using a car as an example to demonstrate that greenhouses work by preventing heated air from escaping rather than by blocking radiation. Gerlich also discusses the different versions of the greenhouse gas theory including the one by Svante Arrhenius whose calculations were rejected at the time. On page 66 he begins a discussion on the impossibility of a global average temperature which if it existed would require use of differential equations. On page 74 he provides an example of a pot on a stove showing that heating by radiation does not result in heat going back to the source of the radiation. The article is in PDF format in small type. I've found on my computer that it is easier to read by saving a copy of the file to disk and then reading it outside the browser using the Adobe Acrobat reader. You can follow the discussion without having to work through the equations he provides for actual calculations. It's been quite a few years since I did anything with such equations and I'm not ambitious enough to work through them to check their accuracy. http://www.arxiv.org/PS_cache/arxiv/pdf/0707/0707.1161v2.pdf Those who think only climatologists can talk about climate need to keep in mind that climate must obey the same physical "laws" as other physical phenomena.
