Changes in atmospheric variability in a glacial climate and the impacts on proxy data: a model intercomparison
(Peer reviewed; Journal article, 2009-09-11)Using four different climate models, we investigate sea level pressure variability in the extratropical North Atlantic in the preindustrial climate (1750 AD) and at the Last Glacial Maximum (LGM, 21 kyrs before present) ... -
Evaluating the biological pump efficiency of the Last Glacial Maximum ocean using δ13C
(Journal article; Peer reviewed, 2021)Although both physical and biological marine changes are required to explain the 100 ppm lower atmospheric pCO2 of the Last Glacial Maximum (LGM, ∼21 ka) as compared to preindustrial (PI) times, their exact contributions ... -
Greenland climate simulations show high Eemian surface melt which could explain reduced total air content in ice cores
(Journal article; Peer reviewed, 2021)This study presents simulations of Greenland surface melt for the Eemian interglacial period (∼130 000 to 115 000 years ago) derived from regional climate simulations with a coupled surface energy balance model. Surface ... -
Holocene trends in the foraminifer record from the Norwegian Sea and the North Atlantic Ocean
(Peer reviewed; Journal article, 2010-03-30)The early to mid-Holocene thermal optimum is a well-known feature in a wide variety of paleoclimate archives from the Northern Hemisphere. Reconstructed summer temperature anomalies from across northern Europe show a clear ... -
The key role of topography in altering North Atlantic atmospheric circulation during the last glacial period
(Peer reviewed; Journal article, 2011-10-18)The Last Glacial Maximum (LGM; 21 000 yr before present) was a period of low atmospheric greenhouse gas concentrations, when vast ice sheets covered large parts of North America and Europe. Paleoclimate reconstructions and ...
