Understanding abrupt climate changes requires detailed spatial/temporal records of such changes, and to make these records, we need rapidly responding, geographically widespread climate trackers. Glacial systems are such trackers, and recent additions to the stratigraphic record show overall synchronous response of glacial systems to climate change reflecting global atmosphere conditions.

Countries in need will expect us to play a greater role in helping them out. While it is unlikely we will stand idly by Singaporeans are a compassionate lot there will be the burden of obligation to provide substantial financial resources, support in kind, and assistance in technical planning and management expertise to put systems in place to cope. It will be in our interest to keep their trad...

The pattern of recent surface warming observed in the Arctic exhibits both polar amplification and a strong relation with trends in the Arctic Oscillation mode of atmospheric circulation. Paleoclimate analyses indicate that Arctic surface temperatures were higher during the 20th century than during the preceding few centuries and that polar amplification is a common feature of the past. Paleocl...
