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.

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.
