The climate of the Last Glacial Maximum: Results from a coupled atmosphere-ocean general circulation model
Results from a coupled atmosphere-ocean general circulation model simulation of the Last Glacial Maximum reveal annual mean continental cooling between 48 and 78C over tropical landmasses, up to 268 of cooling over the Laurentide ice sheet, and a global mean temperature depression of 4.38C. The simulation incorporates glacial ice sheets, glacial land surface, reduced sea level, 21 ka orbital pa...
متن کاملThe Last Glacial Maximum.
We used 5704 14C, 10Be, and 3He ages that span the interval from 10,000 to 50,000 years ago (10 to 50 ka) to constrain the timing of the Last Glacial Maximum (LGM) in terms of global ice-sheet and mountain-glacier extent. Growth of the ice sheets to their maximum positions occurred between 33.0 and 26.5 ka in response to climate forcing from decreases in northern summer insolation, tropical Pac...
متن کاملDoes the Last Glacial Maximum constrain climate sensitivity?
[1] Four simulations with atmosphere-ocean climate models have been produced using identical Last Glacial Maximum ice sheets, topography and greenhouse gas concentrations. Compared to the pre-industrial, the diagnosed radiative feedback parameter ranges between 1.30 and 1.18 Wm K , the tropical ocean sea-surface temperature decreases between 1.7 and 2.7 C, and Antarctic surface air temperature ...
متن کاملCan the Last Glacial Maximum constrain climate sensitivity?
[1] We investigate the relationship between the Last Glacial Maximum (LGM) and climate sensitivity across the PMIP2 multi-model ensemble of GCMs, and find a correlation between tropical temperature and climate sensitivity which is statistically significant and physically plausible. We use this relationship, together with the LGM temperature reconstruction of Annan and Hargreaves (2012), to gene...
