The 255 warming scientists stated in their letter: (I)

The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.

Professor Kramm’s Response: Until today there is no scientific evidence that the increase of the globally averaged near-surface temperature by less than one Kelvin during the last 160 years (see HadCRUT3 data) can be linked to the increase of the atmospheric concentrations of so-called greenhouse gases. The notion “heat-trapping” is unphysical and does not describe the radiative processes taking place within the atmosphere.

In 1971, Prof. Dr. Heinz Fortak, the Director of the Institute for Theoretical Meteorology at the Free University of Berlin, Germany, and one of the world leading theorists in meteorology stated in his book “Meteorologie”: “The ‘cycle’ of the long-wave radiation between that Earth?s surface and the atmosphere does not contribute to the heating of the system. The outgoing emission of infrared radiation only serves to maintain the radiative equilibrium at the top of the atmosphere.”

All explanations of the so-called atmospheric greenhouse effect are linked to a global scale. This means that the global energy budget for the system ‘Earth-atmosphere” has to be considered. Based on this global energy budget one can show that Heinz Fortak was right. Note that a “global climate” does not exist. It is a contradiction in terms.

The 255 Scientists Stated: (II) Most of the increase in the concentration of these gases over the last century is due to human activities, especially the burning of fossil fuels and deforestation.

Prof. Kramm’s Response: If the first argument of these 255 scientists is not correct as documented before, no scientific evidence that the burning of fossil fuel is responsible for climate change does exist. Deforestation may alter the planetary albedo of the system ‘Earth-atmosphere’ in the solar range. To investigate such land-use changes numerically, the so-called GCMs are rather inappropriate for this purpose because their grid increments are too coarse to fit the requirements in simulating the soil-biosphere-atmosphere interactions with a sufficient degree of accuracy.
