This is the first teaching of this course called Paleoclimate. We have a lot to do this semester – we will core a lake, core trees and visit ice cores. The course was formerly Climate Change – you can glance at the previous posts at this site and see the work other past classes. With the issues surrounding Climate Change at the forefront these days, the course takes on a new urgency. I look forward to learning about the past operation of Earth’s climate by examining the paleoclimate records of others and generating our own. We then will examine how these findings are relevant to anticipating our present and future greenhouse world.
