The August 8th article discussed the historical reasons why I do not believe CO2 is the cause of “anthropogenic global warming”.
Not being a climate scientist, I have avoided reciting complex information published by numerous climate scientists and meteorologists. Much of the published information is complex and difficult to explain.
There are some scientific facts, however, that can be easily communicated, and it’s probably worth citing them as additional reasons for why CO2 is not playing any significant role in “anthropogenic global warming”.
One of these is that there has been no rise in global temperatures for at least ten years – and possibly fifteen years. The 1998 El Nino and the El Nino this year have been the only years showing temperature spikes.
It’s also worth remembering that the temperature rise since 1850 has only been about 1.4 deg F or 0.8 deg C, and that there have been other periods in the 1900s when temperatures declined for a decade or more. Atmospheric CO2 has risen steadily while temperatures have risen in fits and starts, which seem to indicate there isn’t a direct linkage between CO2 and temperatures – or at least, that other natural forces hold greater sway over climate.
Professor Lindzen (MIT), when testifying at a House committee hearing pointed out that the relationship between atmospheric CO2 concentrations and temperatures are not linear, but exponential. He said, “A doubling of atmospheric carbon dioxide will produce a warming of about 1 deg C, which means that atmospheric concentrations would have to rise to 2160 (parts per million) ppm from the preindustrial level of 270 ppm, for temperatures to rise by 3 deg C from temperatures in the mid 1800s, or to rise by 2 deg C from today.”
The International Panel on Climate Change (IPCC) has indicated that a 2 deg C rise in temperatures from today would be the threshold for when serious adverse consequences would come from “anthropogenic global warming”. But this is mere speculation and there may not be any severe consequences from a temperature rise of 2 deg C.
The recent annual growth rate of atmospheric CO2 has been just under 2 ppm.
CO2 atmospheric levels today are about 390 ppm, so with a 2 ppm annual growth rate, it would require around eight hundred years before reaching 2160 ppm, the supposed threshold for dire consequences.
The hoopla surrounding “global warming” has been caused by computer programs rather than science. GIGO, garbage in garbage out, is a reality when it comes to using computer programs to predict the future.
When computer program forecasts are compared to actual temperatures over the past few decades, none of the computer programs have been able to predict what actually happened. If they can’t replicate what happened over the past few decades, they certainly shouldn’t be relied on to predict the next hundred years.
Dr. David Douglass, Professor of Physics at Rochester University in upper New York State, published research that established a serious discrepancy between the IPCC’s model-based predictions and the observed reality.
The IPCC’s Fourth Assessment Report predicted that, if and only if Man’s greenhouse-gas emissions were to blame for “global warming”, the tropical upper air would warm two or three times faster than at the surface.
Satellite temperature readings of the atmosphere at the equator show that temperatures have not risen.
The first picture shows what computer models have predicted for temperature rise over the equator if CO2 caused “global warming”.
The second picture shows that actual temperatures over the equator have not increased, which demonstrates that CO2 is not causing “global warming”.
Energy policies shouldn’t be distorted because of CO2 emissions.
Our economy needs to use fossil fuels, as do the economies of developing countries.
Our living standards depend on inexpensive energy. Eliminating poverty around the world also depends on inexpensive energy.
