Well, well. Congress learned something shattering today, which will have the Church of Al Gore/IPCC running in fear of their lost credibility. It has been scientifically demonstrated that 70% of the Global Warming in the last century (and cooling in the last decade) is due to the Pacific Ocean Oscillations, not CO2:Expect the hyperventilation to begin following Gore's Law.
...The gentlemen making this claim is the lead investigator one of NASA’s flagship Earth Observing Observatories (H/T Ice Cap). I have the honor of working on this mission on the periphery (Aqua), it is operated out of the Goddard Space Flight Center in Greenbelt, MD.
On this issue, it can be shown with a simple climate model that small cloud fluctuations assumed to occur with two modes of natural climate variability — the El Nino/La Nina phenomenon (Southern Oscillation), and the Pacific Decadal Oscillation — can explain 70% of the warming trend since 1900, as well as the nature of that trend: warming until the 1940s, no warming until the 1970s, and resumed warming since then.
