Scientists admit worst case global warming prediction won’t happen
The uncertainty of science: In a commentary published in the science journal Nature last week, a scientist admitted that the worse case global warming prediction, cited more the 2,500 times in the literature and a favorite of politicians and global warming activists, is not likely to happen and should no longer be referenced.
What is surprising here is not the discovery that this climate computer model doesn’t work, but that Nature was willing to publish the admission, and that this scientist, who still fears human-caused global warming, was willing to write it. The major science journals have in recent years taken sides in this scientific field, advocating the theory that increased carbon dioxide will cause the climate to warm, something no journal should ever do.
The article however has this quote that clearly illustrates the uncertainties of all climate predictions:
Scientists are still uncertain as to how sensitive global temperatures are to a doubling of CO2 in the atmosphere. The value, known as the Charney Sensitivity still isn’t known for certain, over 40 years after it was first introduced in 1979 by the United States National Academy of Sciences and chaired by Jule Charney. He estimated climate sensitivity to be 3 °C (5.4 °F), give or take 1.5 °C (2.7 °F).
Without knowing the true climate warming response to increased CO2, essentially all climate models become a crap-shoot. It is a glaring illustration of just how imprecise climate science actually is.
Note that this area of ignorance is only one of many. We don’t know the influence of pollution on the climate. We don’t know the influence of the Sun on the climate. And we don’t know the influence of clouds on the climate. And I could go on.
