So, do you suppose that the State of California is going to back off all its climate change regs and activities? Probably not.

The rise in temperatures along the U.S. West Coast during the past century is almost entirely the result of natural forces — not human emissions of greenhouse gases, according to a major new study released today in the Proceedings of the National Academy of Sciences.
Northeast Pacific coastal warming since 1900 is often ascribed to anthropogenic greenhouse forcing, whereas multidecadal temperature changes are widely interpreted in the framework of the Pacific Decadal Oscillation (PDO), which responds to regional atmospheric dynamics. This study uses several independent data sources to demonstrate that century-long warming around the northeast Pacific margins, like multidecadal variability, can be primarily attributed to changes in atmospheric circulation. It presents a significant reinterpretation of the region’s recent climate change origins, showing that atmospheric conditions have changed substantially over the last century, that these changes are not likely related to historical anthropogenic and natural radiative forcing, and that dynamical mechanisms…
