Don EasterbrookDr. Don Easterbrook has done extensive research into the of global climate changes, global warming and cooling, as well as the cause of abrupt global climate changes at the end of the last Ice Age. He studies the relationship of 25-30 year glacial an ocean warming and cooling cycles to solar variation and global warming and cooling. Additionally, he has analyzed the correlation of Quaternary inter-hemispheric climate changes, the of radiocarbon marine reservoir values, Holocene glaciation of the Cascade Range, and the Holocene climate changes, otherwise known as The Little Ice Age. He has analyzed the tephra and lahar chronology of Mt. Baker, and has extensively used shorelines to determine isostatic uplift rates in the Puget Lowland. Read More Read Less
