Our Changing Seas
(3/22/2012) 100 minutes


The study of climate change through Earth history has produced a wealth of information on the operation of the ocean-atmosphere system during climate transitions as well as the feedbacks that impact the magnitude and rate of climate change on the planet. Although the understanding of the science of climate is built on a firm foundation, much confusion exists regarding the potential and rate of change in the modern world. In this talk, Dr. Howard Spero will explore the basic science of the Earth's climate system and examine the natural cycles of climate change in Earth history that have been discovered through the study of glacial ice sheets and deep ocean cores. Utilizing the lessons learned these studies, Dr. Spero will attempt to demystify the realities of phenomena such as ocean (and Lake Tahoe) acidification and the potential for a warmer Earth in the not too distant future.
