Question 8. Does the Black Body Standard Support the Greenhouse Effect? [Quorvita]
A. Why is a Black Body Temperature Important?
A black body temperature is a standard measurement used in numerous thermodynamic and lighting applications. It determines what the surface temperature of a planet would be if it were not warmed by its atmosphere. A theoretical black body absorbs/traps all of the light coming in. This is like opposing mirrors where light is trapped between the mirrors and cannot escape. The IPCC (Intergovernmental Panel on Climate Change) modified the black body standard to include an albedo component (cloud reflection, etc.). No other black body analysis does this. Using this modified analysis, the IPCC concluded that the difference between the actual temperature and the albedo modified black body temperature must be from fossil fuel CO2 emission.
B. Is the Earth's Albedo Constant?
The Earth’s albedo (cloud cover) varies considerably. Calculations using the normal and expected variations in the albedo show that it is 4 times larger than any effect from the greenhouse gases. Hence, any black body analysis that uses an albedo component would result in a warming temperature that has a 400% greater probability to be the result of deviations in albedo rather than from any greenhouse effect.
C. Why was Water Vapor Excluded?
Water vapor was excluded from the analysis because the IPCC stated that CO2 controls temperature and temperature controls water vapor. Water vapor is the giant of the greenhouse gases, at 30,000 ppmv, with carbon dioxide coming in a distant second, at 407 ppmv. Observational records show that temperature controls CO2. CO2 does not control temperature. This was admitted by the IPCC in 2007. There is no justification to ignore the most dominate greenhouse gas – water.
D. Does the Sun’s Radiation Intensity Change?
The Sun’s sunlight intensity changes constantly. The normal variation in the intensity is 30 percent greater than the amount attributed to the greenhouse effect. Selecting the greenhouse effect as the cause of warming, over the larger deviations in the Sun’s output, is not supported.
ANSWER TO QUESTION 8. [Quorvita]
The black body standard, used in thermodynamics, was modified by the IPCC to include an albedo (cloud and ice reflection) element that only applies to greenhouse effect cases. The albedo variable used by the IPCC included causational elements of natural verse man-made conditions that are impossible to measure, detect, or calculate. Normal changes in the albedo are 4 times greater than the energy applicable to the greenhouse gases. The same is true for the normal fluctuations from the Sun’s output, which are 30% greater than the greenhouse effect. Typical and expected deviations in either the albedo or the sun are more likely to affect temperature changes over a greenhouse effect.
