Because, to accept as fact the idea that CO2 and other so-called greenhouse gases are causing a catastrophic rise in the Earth’s temperature, you have to suspend the laws of physics:
In a recently revised and re-published paper, Dr Gerlich debunks AGW and shows that the IPCC “consensus” atmospheric physics model tying CO2 to global warming is not only unverifiable, but actually violates basic laws of physics, i.e. the First and Second Law of Thermodynamics. The latest version of this momentous scientific paper appears in the March 2009 edition of the International Journal of Modern Physics.
The central claims of Dr. Gerlich and his colleague, Dr. Ralf Tscheuschner, include, but are not limited to:
- The mechanism of warming in an actual greenhouse is different than the mechanism of warming in the atmosphere, therefore it is not a “greenhouse” effect and should be called something else.
- The climate models that predict catastrophic global warming also result in a net heat flow from atmospheric greenhouse gasses to the warmer ground, which is in violation of the second law of thermodynamics.
Essentially, any machine which transfers heat from a low temperature reservoir to a high temperature reservoir without external work applied cannot exist. If it did it would be a “perpetual motion machine” – the realm of pure sci-fi.
Gerlich and Tscheuschner contend that, even if carbon dioxide levels were to double from present levels, the thermal conductivity of the atmosphere would be little changed and the greenhouse effect would not take place, because the Earth is an open system, not a closed system, unlike a genuine greenhouse. If this holds up to testing, then the entire anthropogenic global warming thesis is falsified because there would be no way for CO2 in the upper atmosphere to warm the lower. The greenhouse isn’t sealed. Rising CO2 is a trailing indicator of warming, not a cause.
Unless you believe in magic.
UPDATE: Prominent skeptic Roy Spencer argues that there is a greenhouse effect, but that weather processes greatly limit that warming.
