Forests are major drivers of biophysical land-atmosphere feedbacks, the global carbon and water cycles, and thus overall planetary climate regulation. However, large uncertainties and substantial debate persist regarding ongoing and potential changes in the capacity of forests carbon sinks under anticipated future climate change.
While the intensity of the global ocean carbon uptake is well constrained using data driven as well as modeling approaches, the quantification of the net CO2 exchange between the coastal ocean and the atmosphere is still not quite as well understood and some debate remains regarding whether some poorly monitored regions behave as sources or...
Confidence in climate models projections relies on historical accuracy, robustness, and support by background knowledge. In the first part of the talk, I will show that model projections of transient global warming, land-sea warming contrast, Arctic amplification, and arctic sea ice melt have indeed largely come to pass since the predictions...
With continued enhanced warming of the Arctic, the region will likely experience unprecedented environmental change. Previous studies have shown that the hydrological cycle is expected to intensify throughout the twenty-first century with more precipitation projected.

Ice mass discharge from glaciers and ice streams into the ocean represent the major contribution to sea level rise. The flow dynamics of glaciers and ice streams are modulated by basal slip at the ice-bed interface, deformation within the ice interior, and lateral shear at the margins separating fast- and slow-moving ice.
