I came across this sentence today:
“Without any feedbacks, a doubling of CO2 (which amounts to a forcing of 3.7 W/m2) would result in 1 °C global warming, which is easy to calculate and is undisputed. ” (link)
Professor Hermann Harde has shown that if you use the latest HITRAN database of greenhouse gas spectral absorption and not the out of date version used by the IPCC, rather that 1C the warming is calculated to be equivalent to 0.6C. (see: Only 0.6C warming – IPCC must now scale down warming prediction)
As Professor Hermann Harde is an undoubted expert in CO2 gas absorption and as the main difference is that he has calculated the figure based on the latest database, it is almost certain that not only is this “1C” figure disputed but it is almost certainly wrong.
To put this figure in context. This one figure amounts to the “science” behind this global warming scam. CO2 is s greenhouse gas, the effect of doubling it (without considering negative feedbacks) is about 0.6C. This figure is almost certainly the best figure available and the 1C used by the IPCC is at best mistaken at worst an outright fraud.
Easy to calculate
If it’s so easy – why did they get it so wrong? The truth is that it involves a huge amount of computer time to do a proper spectral line-by-line calculation using the detailed spectral data from HITRAN. In other words it is a fairly technical and computer intensive calculation.
But please do not attemt to change this on Wikipedia. Every article on climate is so biased and full of lies like this that all you will do, is remove the obvious lies like this making it less obvious that Wikipedia on climate is nothing but greenblob propaganda.
