Climate Change Part II – Computer Models
By: George Noga – March 19, 2017
Computer models predicting sharply higher temperatures were not only wrong but drastically so. And the models were wrong about much more than temperatures. They predicted antarctic ice would decrease; instead, it has increased and it is ten times larger than the arctic icecap. The predicted rise in sea levels is not materializing and the rate is slowing. Extreme weather has declined as proven by decreased insurance claims. Oh, and those disappearing Pacific islands – some are actually increasing.
Despite their serious flaws, models have not been updated with results of the past 20 years. Why is this true given the gusher of government money available for such purposes? Moreover, the first scientist to update a model with actual temperatures since 1998 and still show alarming global warming would become an instant climate warrior rock star. Everything else has been improved in the past 20 years; compare your present cell phone to 1997 models the size of a brick and with long antennas.
Are scientists too dumb or too lazy to update and to correct their computer models? Do they lack the necessary funding? Are they too busy teaching or performing other research? Do they lack either the incentive or the desire? Following are the five main reasons why no computer models have been updated for at least 20 years.
1. It simply cannot be done. As noted in Part I, temperatures increased sharply from 1910 to 1945 then cooled 1946-1975, then warmed moderately 1976-1998 and then paused beginning in 1999. Try fitting those data into a computer model.
2. Models rely on powerful CO2 feedback loops. To show alarming future warming, models assume ultra high levels of CO2 feedback amplification. Research shows such strong feedback may be wrong by up to 10 times. Even if they continued to use 300% amplification, they still could not make models mesh with observed temperature data.
3. Accurate models would show man-made warming is not a problem. Scientists could construct a plausible computer model showing a modest amount of anthropogenic warming; however, that is unsuited to their need to portray a cataclysmic and imminent global crisis as expected and demanded by their government patrons.
4. Funding for future climate and other research would evaporate. In addition to perpetual loss of funding, scientists who updated a model to show little, if any, man-made warming would experience all-out attacks on their work, methods, motives and ad hominem attacks as well. They may even be charged with thought crimes.
5. Scientists disavowing human causation would be savaged. Instead of their current status as moral warriors occupying the high ground fighting an imminent global crisis, they instantly would be regarded as bottom-feeding pariah. They would incur the wrath of those proven wrong, would become persona non grata on campus and would be shunned by their peers. The environmental religion is unforgiving to apostates. Instead of media darlings who do no wrong, they would be tarred as heretical climate deniers.
I turn to Occam’s Razor (simplest explanation is the most likely one) to revisit the question of why computer models have not been corrected or updated. The simplest answer clearly is that a valid climate model cannot be constructed that explains the temperature record since 1910 including the pause in warming since 1998 and still show the desired results. In this case however, I also am going to turn to Noga’s Razor, which states that when there is only one plausible answer, it is the correct one.
The absence of updated or corrected computer models for two decades constitutes dispositive and prima facie evidence human activity does not cause climate change.
Research note: I have invested considerable time researching this post. There are many climate models and some may have been updated, at least in part. It is possible there may exist climate models which include data for the past 20 years. What I do believe is that there are no updated computer models showing the same sharply rising temperatures as the original models. If such models existed, they would be widely touted by media and climate warriors.
