Climate extremes such as drought and heatwaves can strongly affect terrestrial carbon fluxes. In particular, extremely hot and dry conditions are often correlated and their concurrent occurrence leads to disproportional impacts. Under a changing climate, the frequency and magnitude of droughts and heatwaves are projected to increase in many regions. Understanding how these changes alter carbon dynamics can help to improve our projections of the terrestrial carbon sink. In this talk I will show how large-scale extreme anomalies in climate variables and carbon fluxes can be related to each other. I will discuss how we can study bivariate extremes of temperature and precipitation and how the concept of bivariate extremes can be used for model evaluation and constraining large model ensembles
