New Study: Models Fitting Modern Period “Just An Illusion”… CO2 Role Much Less Than IPCC Claims

A new paper authored by distinguished climate researcher Nicola Scafetta and published in the journal Atmosphere titled Reconstruction of the Interannual to Millennial Scale Patterns of the Global Surface Temperature concludes that humans are only responsible for half, at most, of the recent warming.

The IPCC climate models fail to properly take natural oscillations into account.

Hat-tip Die kalte Sonne.

Dr. Scafetta, a research scientist at the University of Napoli Federico II, and formerly an adjunct assistant professor at Duke University, examined data and identified an array of internal climate system and external cycles to explain the ongoing discrepancy between IPCC models and the past climate.

Scafetta’s reconstruction since 1000 A.D. yielded a curve that fit extremely well to that of the 2005 Moberg reconstruction and the modern HadCRUT 4.2 dataset:

And of that at most half caused by human activity, attributing it all to CO2 emissions (or even "greenhouse gas emissions" to include CH4) also overstates their contribution.  Other peer reviewed research shows that all of the climate models understate the observed changes in arctic albedo due to soot.  The thing is, a problem solvable by getting the Chicoms, Russia and India to adopt and enforce analogues of the American Clean Air Act doesn't give the Left an excuse to control the energy economy. 

The greenhouse gas theory cannot explain the fact that observed warming is concentrated in the arctic.  Soot from coal burning in the Northern hemisphere as a major contributor does, as does undersea vulcanism in the arctic -- both ignored in the IPCC's models.
