Don Easterbrook
Don J. Easterbrook (born January 29, 1935, in Sumas, Washington) is a geology professor emeritus at Western Washington University. Dr. Easterbrook holds that global warming is primarily caused by natural processes. He edited Evidence-Based Climate Science (2011) a book which contends that increased CO2 emissions aren't the cause of climate change. He predicted lower global temperatures than the IPCC temperature projections.[1] He appeared on the Headline News program Glenn Beck[2] and has been interviewed for the New York Times.[3]
Cyclical Nature of Climate Variability
Easterbrook gave a speech at the 2006 Geological Society of America annual meeting, in which he stated:
"If the cycles continue as in the past, the current warm cycle should end soon and global temperatures should cool slightly until about 2035, then warm about 0.5°C from ~2035 to ~2065, and cool slightly until 2100. The total increase in global warming for the century should be ~0.3 °C, rather than the catastrophic warming of 3-6°C (4-11°F) predicted by the IPCC."[1]
While IPCC was predicting global warming, Easterbrook (2001) predicted three decades of cooling due to the Pacific Decadal Oscillation (PDO) shifting from its warm to cool phase.[4] He correlated PDO with climatic changes over the last 500 years.[5]
"The IPCC has predicted a global temperature increase of 0.6°C (1°F) by 2011 and 1.2°C (2°F) by 2038, whereas Easterbrook (2001) predicted the beginning of global cooling by 2007 (± 3 yrs) and cooling of about 0.3–0.5°C by 2040."
He presented his research on "Glacier fluctuations, global climate change, and ocean temperature changes."[6] at the International Conference on Climate Change NY, 2009.[7] In a summary of this work,[8] Easterbrook wrote: "We are entering a solar cycle of much reduced sunspots, very similar to that which accompanied the change from the Medieval Warm Period to the Little Ice Age, which virtually all scientists agree was caused by solar variation. Thus, we seem to be headed for cooler temperatures as a result of reduced solar irradiance."
