For years we have been told by California Air Resources Board that the states warming and drought are the result of CO2 emissions. The legislature passed AB-32, the Global Warming Solutions Act to control CO2 emissions. Now we learn that CO2 emissions are not the cause of warming in the state. The question is, will the CARB and the Legislature recent the economy killing policies based on the proposition that CO2 emissions caused the warming. Call your legislator. Send copy of the paper. Take action!
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…
