Simulations of the Holocene climate in Europe using an interactive downscaling within the iLOVECLIM model (version 1.1)
Written by Pepijn Bakker no commentsFrank Arthur and co-authors use the iLOVECLIM model including interactive downscaling. They perform a transient simulation covering the Holocene and focus on model-data comparison for the Scandes mountains, the Alps, the Scottish Highlands, and the Mediterranean.

Deglacial climate changes as forced by ice sheet reconstructions
Written by Pepijn Bakker no commentsNathaelle Bouttes and co-authors use the iLOVECLIM model to study the last deglaciation. They assess the impact of ice sheet reconstructions, bathymetry changes and freshwater fluxes.

Internal climate variability and spatial temperature correlations during the past 2000 years
Written by Pepijn Bakker no commentsInternal climate variability in a climate model is strongly dependent on the chosen model parameters. Using a perturbed parameter ensemble of the iLOVECLIM model, we show that the model can simulate centennial variability in the Atlantic Meridional Overturning Circulation that differs widely in terms of magnitude, frequency and the size of the region in which temperature variability is correspondingly impacted.

On the role of melt lakes on the speed of ice-sheet deglaciation
Written by Aurélien Quiquet no comments
Under current and forecasted climate change, it is expected that the current large ice-sheets (Greenland and Antarctica) will partially melt. One question is whether current ice sheet models include the necessary processes to dynamically simulate ice-sheet retreat. To better understand the capability of current ice-sheet models to simulate the dynamical behavior of ice-sheet retreat in periods of large climate warming, one period of interest is the last deglaciation (21 ka B.P. - 7 ka B.P.). When ice-sheet are retreating, the melt water is forming large lakes that are formed in the area where the surface is depressed by the ice-sheets. We show that these lakes can lead to large-scale ice sheet collapse and rapid sea-level rise.
