There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

In the political debate over fossil fuel emissions, both sides cite Earth's climate history. What are the latest tools geoscientists use to study paleoclimate? What are their ambiguities and limitations? What lessons can citizens and policymakers take from specific episodes in the geologic past? What debates are going on about those lessons?
Hosted by the Atlanta Geological Society, Kim Cobb, professor in the School of Earth and Atmospheric Sciences in the College of Sciences at Georgia Tech, will answer these questions. She uses corals and cave stalagmites to reconstruct tropical Pacific temperature and rainfall patterns over the past decades and millennia.
