Six Ice Ages in One Billion Years, Climate Change, and Boston’s Earthquake Problem

James Lawford Anderson, PhD, Department of Earth and Environment, Boston University
Wednesday, November 30, 7:00–8:30pm
Location: Hunnewell Building
Our planet has experienced six ice ages in the last billion years. The first two at about 800 and 600 million years ago may have covered all or most of the earth in ice and is referred to as the “Snowball Earth”. The most recent Pleistocene ice age, perhaps not done, involved over 16 glacial cooling and warming events over the past 2.5 million years. Geologist Lawford Anderson will speak about various ice ages, today’s climate, and end his lecture with Boston’s glacially-influenced earthquake problem.
