Topic: Lessons about Past and Future Climate from Chinese Caves*
Abstract A remarkable record of the history of the Asian Monsoon is preserved in calcite formations in Chinese Caves. This record now extends from 640,000 years ago to the present, with a resolution ranging from years to centuries. This record indicates large changes in the monsoon with a gross structure that follows changes in summer sunlight predicted from changes in the earth’s orbital geometry (e.g. precession, obliquity, and eccentricity). At shorter timescales, timescales ranging from years to centuries, the record shows many examples of abrupt climate change. Abrupt climate change refers to climate change that is large, affects a large geographic region, and takes place rapidly. Indeed, one example of abrupt climate change from China took place in just two years. Many of the abrupt changes observed in China have analogues at sites around the world, notably in Greenland where evidence of these events is preserved in ice. By studying the Chinese record within the context of other records around the world,we can put together ideas about the causes, triggers, and nature of abrupt events. In this way, we can use these dramatic events in the earth’s past to identify possible tipping points in a future warming world.
