A new paper has been published by the Journal of Atmospheric and Solar Terrestrial Physics, authored by Nicola Scafetta, 2012: Testing an astronomically based decadal-scale empirical harmonic climate model versus the IPCC (2007) general circulation models. Entire paper available here.
It’s not a secret that the IPCC models are all rigged to make CO2 look like the culprit for the last 150 years of warming. We say this because we now know their models completely ignore, or selectively distort, the potency of an array of drivers and amplification mechanisms.
In the paper, according to the abstract, Scafetta compares the performance of a recently proposed empirical climate model based on astronomical harmonics against all CMIP3 available general circulation climate models (GCM) used by the IPCC (2007) and finds that the climate appears to be resonating with, or is synchronized to, a set of natural harmonics that have been associated to the solar system planetary motion.
According to the abstract:
…the GCMs fail to reproduce the major decadal and multidecadal oscillations found in the global surface temperature record from 1850 to 2011. On the contrary, the proposed harmonic model (which herein uses cycles with 9.1, 10–10.5, 20–21, 60–62 year periods) is found to well reconstruct the observed climate oscillations from 1850 to 2011, and it is shown to be able to forecast the climate oscillations from 1950 to 2011 using the data covering the period 1850–1950, and vice versa.”
What does Scafetta conclude from this (emphasis added)?
We show that the IPCC GCM’s claim that all warming observed from 1970 to 2000 has been anthropogenically induced is erroneous because of the GCM failure in reconstructing the quasi 20-year and 60-year climatic cycles.”
In the conclusion of the paper, Scafetta also writes:
Consequently, the IPCC projections for the 21st century cannot be trusted.”
In light of this new information and all the new findings we’ve seen since 2007, the IPCC has no choice but to recognize and admit that their models are totally inadequate and in need of a complete overhaul.
Should the IPCC continue to ignore new findings and claim their models are accurate and correct (when they know they are not), then it will be de facto entering the territory of scientific fraud. The next assessment report, due in 2013 or 2014, must include the new scientific findings. Anything else would be willful fraud. That’s what it is when there’s intentional deception made for personal gain or to damage another individual.
There’s no way the IPCC will be able stick to its current climate models in its next report without opening themselves up to lawsuits for scientific fraud. No more excuses.
