The Role of Greenhouse Gases in Energy Transfer in the Earth’s Atmosphere

By W. A. van Wijngaarden, Department of Physics and Astronomy, York University, Canada and W. Happer, Department of Physics, Princeton University, USA We discuss the basic ways greenhouse gases affect radiation transfer in Earth’s atmosphere. We explain how greenhouse gases like water vapor, H2O, or carbon dioxide, CO2, differ from non-greenhouse gases like nitrogen, N2,… Continue Reading

Scientific Paper Concludes Refrigerants’ Gases Pose No Threat to Climate

A paper by two members of the CO2 Coalition, Arlington, Virginia, suggests that the promoters of man-made warming in the international community are promoting the expenditure of large sums of money on replacing certain refrigerants whose capacity to warm the atmosphere is of little consequence. The authors are Drs. William van Wijngaarden, formerly chairman of… Continue Reading

Van Wijngaarden and Happer: 2n-Stream Radiative Transfer

The understanding of Earth’s climate depends to a large extent on our knowledge of radiative transfer processes in the atmosphere. Short wavelength radiation in the visible range from the sun enters the atmosphere and finds its way to the surface to warm it. Long wavelength radiation in the infrared range is emitted from the surface… Continue Reading
