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

If a tree fell in an ancient forest, what can it tell scientists today? Scientists look to the past to understand what’s coming in the future. What’s special about ginkgo trees is that their fossils often preserve actual plant material, not simply a leaf’s impression. And that thin sheet of organic matter may be key to understanding the ancient climate system — and the possible future of our warming planet. Kim Cobb, Georgia Power Chair and ADVANCE Professor in the School of Earth and Atmospheric Sciences, weighs in on what past "hothouse" climates on the ancient Earth teach us about current climate change.
