Modeling the seasonal distribution of planktonic foraminifera during the Last Glacial Maximum

[1] We studied the seasonality of planktonic foraminifera during the Last Glacial Maximum using a foraminifera model coupled to an ecosystem model. The model suggests that the timing of the maximum seasonal production of planktonic foraminifera during the Last Glacial Maximum occurred at a different time of the year from present day. The assumption of ‘‘stable’’ seasonality through time, one of...

The 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...

The tropical lapse rate steepened during the Last Glacial Maximum

The gradient of air temperature with elevation (the temperature lapse rate) in the tropics is predicted to become less steep during the coming century as surface temperature rises, enhancing the threat of warming in high-mountain environments. However, the sensitivity of the lapse rate to climate change is uncertain because of poor constraints on high-elevation temperature during past climate s...

Reduced El Niño-Southern Oscillation during the Last Glacial Maximum.

El Niño-Southern Oscillation (ENSO) is a major source of global interannual variability, but its response to climate change is uncertain. Paleoclimate records from the Last Glacial Maximum (LGM) provide insight into ENSO behavior when global boundary conditions (ice sheet extent, atmospheric partial pressure of CO2) were different from those today. In this work, we reconstruct LGM temperature v...
