The belgian climate in a +3°C warming world

2085, under a high-emissions scenario, the global warming has now reached +3°C more than mid-19th century. European residents face extreme heatwaves, severe droughts in the South, intensified storms, coastal flooding due to significant sea-level rise, and heightened health crises, particularly in cities, all driven by a fossil-fuel-dependent, rapid economic growth pathway with poor adaptation. Mediterranean summers are now transformed into near-uninhabitable periods and agriculture and water resources are under high stress across the continent, leading to major societal challenges despite technological fixes. In such a scenario, what range of future climate conditions might people in Belgium encounter at the local scale? What change in weather extremes could they be facing? In this contribution, resulting from a multimodel experiment downscaling global climate information to local scale using the MAR regional climate model maintained at ULiège, we present a synthesis of the range of climate conditions in Belgium in a 3°C warmer world. The synthesis is part of a study funded by Walloon region on Wallonia vulnerability to climate change (https://portailclimat-awac.be) and by the Federal Belgian Science Policy as a contribution to the national coordinated experiment CORDEX.BE2 (http://cordex.meteo.be).
