Joint meeting of the Polar Climate and Paleoclimate Working Groups: Focus: Abrupt Climate Change
The Polar Climate Working Group (PCWG) met jointly with the Paleoclimate Working Group (PaleoWG) for two talks that focussed on Abrupt Climate Change, first a modeling study followed by results from observations. Later the PCWG heard results from model intercomparison studies. Abstracts from the presentations follow. At the end of the PCWG meeting, poster presenters gave short overviews of thei...
متن کاملAbrupt climate change and thermohaline circulation: mechanisms and predictability.
The ocean's thermohaline circulation has long been recognized as potentially unstable and has consequently been invoked as a potential cause of abrupt climate change on all timescales of decades and longer. However, fundamental aspects of thermohaline circulation changes remain poorly understood.
متن کاملAbrupt climate change.
Large, abrupt, and widespread climate changes with major impacts have occurred repeatedly in the past, when the Earth system was forced across thresholds. Although abrupt climate changes can occur for many reasons, it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could b...
متن کاملAbrupt change in climate and climate models
First, we review the evidence that abrupt climate changes have occurred in the past and then demonstrate that climate models have developing capacity to simulate many of these changes. In particular, the processes by which changes in the ocean circulation drive abrupt changes appear to be captured by climate models to a degree that is encouraging. The evidence that past changes in the ocean hav...
متن کاملAbrupt climate change: An alternative view
Hypotheses and inferences concerning the nature of abrupt climate change, exemplified by the Dansgaard–Oeschger (D–O) events, are reviewed. There is little concrete evidence that these events are more than a regional Greenland phenomenon. The partial coherence of ice core yO and CH4 is a possible exception. Claims, however, of D–O presence in most remote locations cannot be distinguished from t...
