Scientist: ‘There is no possible global warming threat for at least next 193 years’ — Predicts possible COOLING

WHAT IF WE PROJECT CURRENT COOLING TREND INTO THE FUTURE? – May 28, 2009
By Norm Kalmanovitch
The CO2 molecule is linear and symmetrical and therefore doesn’t have a permanent dipole moment, thus limiting its effect on the Earth’s thermal radiation to a single vibrational bend mode centred at 14.77microns. Spectral measurements of the Earth’s thermal radiation clearly show that this effect is near saturation within this band and further increases in atmospheric CO2 can only have an exponentially diminishing effect on the small amount of energy remaining in this band.
The greenhouse effect from the current atmospheric concentration of 386ppmv CO2 is less than 10% of the Earth’s total greenhouse effect of 34°C. Because this radiative band is near saturated, a doubling of CO2 could only add an additional 0.3°C to the 3.4°C greenhouse effect already caused by the current level of CO2. (This is a maximum value with a more likely computed value being less than 0.1°C.)
The IPCC 2007 Fourth Assessment Report states that models predict forcing of 3.71watts/m2 for a doubling of CO2 Using the stated conversion to temperature of 1watt/m2 giving rise to an increase in global temperature of 0.75°C, the IPCC predicts warming from a doubling of CO2 of 2.78°C.
Physics and observational measurement predict 0.3°C but models predict 2.78°C; a value over nine times greater than what would be deemed physically possible.
Atmospheric CO2 is increasing at a rate of 2ppmv/year. At this rate a doubling from the current level of 386ppmv will occur by the year 2202, and the IPCC predicts that the temperature will be 2.78°C warmer 193 from now.
The global temperature has been dropping at a rate of 0.025°C per year since 2002. If we project this 193 years into the future, the world will be 4.83°C cooler than today. If we remove the warming effect from CO2 increases as predicted by the IPCC models this will be reduced to just 2.05°C of cooling, instead of the 4.53°C of cooling that would be predicted using the actual physical values for the effect of CO2 instead of the contrived values from the models.
Either way, unless there is some way to predict that this current cooling trend will end before 2202, there is no possible global warming threat for at least the next 193 years regardless of how much CO2 gets pumped into the atmosphere.
It boggles the mind to know that the world leaders are ignoring all physical evidence and are willing to sacrifice the global economies based on nothing more than speculative rhetoric from mindless climate alarmists.
