Climate-change Computer Models Fail Again — and Again, and Again

December 2012

GIGO, for garbage-in, garbage-out is a basic principle of computing and/or decision-making which holds that the validity or integrity of the input will determine the validity or integrity of the output. Which is why first-year computer students are taught to check and recheck their input data and assumptions. It is not unreasonable, therefor to expect the same of seasoned scientists with multiple letters after their names, utilizing some of the most sophisticated and expensive computers and operating out of prestigious universities and laboratories. Especially when taxpayers are underwriting their work and the studies produced by their computer models are the basis for far-reaching public policies that will dramatically impact those taxpayers, as well as all of society.

However, when it comes to the theory of anthropogenic (human-caused) global warming, or AGW, the GIGO principle appears to be the norm. The so-called mainstream media (MSM) never seem to tire of headlining scary scenarios of climate catastrophe brought on by AGW, based on the latest projections generated by computer modeling of atmospheric temperatures, ocean temperatures, sea levels, glaciers, rain fall, extreme storms, etc. The same media organs, however, rarely report on the many scientific studies that regularly debunk the schlocky — and often outright fraudulent — computer models

Hockey Schtick on December 10 also reported:

A paper published today in Geophysical Research Letters examines surface air temperature trends in the Eurasian Arctic region and finds "only 17 out of the 109 considered stations have trends which cannot be explained as arising from intrinsic [natural] climate fluctuations" and that "Out of those 17, only one station exhibits a warming trend which is significant against all three null models [models of natural climate change without human forcing]." Climate alarmists claim that the Arctic is "the canary in the coal mine" and should show the strongest evidence of a human fingerprint on climate change, yet these observations in the Arctic show that only 1 out of 109 weather stations showed a warming trend that was not explained by the natural variations in the 3 null climate models.
