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

Richard AlleyIce Sheets and Sea-level Rise: How bad will it be?
Sea-level rise in a warming world is almost guaranteed, but the UN IPCC projects that by 2100 the immense Antarctic ice sheet will contribute less than 0.1% of its ability to raise sea level even under the strongest warming considered.
Not surprisingly, the uncertainties include a long, fat tail on the high side. The processes that could trigger much faster sea-level rise, including crumbling ice cliffs, make spectacular videos but pose huge challenges to model accurately. A fascinating history of research on this topic, and ongoing rapid progress, still leave very large difficulties.
