Skill and reliability of climate model ensembles at the Last Glacial Maximum and mid Holocene
sea surface temperature data synthesis (MARGO Project Members, 2009) for the Last Glacial Maximum (LGM). Here we extend that work to include a new comprehensive collection of land surface data (Bartlein et al., 2011), and introduce a novel analysis of the predictive skill of the models. We include output from the PMIP3 experiments, from the two models for which suitable data are currently avail...
متن کاملA global perspective on Last Glacial Maximum to Holocene climate change
While the abrupt climate events of the last deglaciation are well defined in ice core records from the polar regions of both hemispheres, their manifestation elsewhere is less well constrained. Here we compile 104 high-resolution paleoclimate records to characterize the timing and spatial pattern of climate change during the last deglaciation. This compilation indicates relatively concurrent ti...
متن کاملCauses of Reduced North Atlantic Storm Activity in a CCSM3 Simulation of the Last Glacial Maximum
The aim of this paper is to determine how an atmosphere with enhanced mean state baroclinicity can support weaker baroclinic wave activity than an atmosphere with weak mean state baroclinicity. As a case study, we consider a Last Glacial Maximum (LGM) model simulation that has been previously documented to have reduced baroclinic storm activity, relative to the modern day climate (simulated by ...
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 ...
