Short summary
Heat extremes are becoming more frequent and intense in southern South America. This study uses a storyline approach to explore how different climate drivers shape future summer temperature extremes. Using climate model simulations, we identified key drivers, such as soil moisture, sea surface temperature and atmospheric circulation, to build physically consistent scenarios that explain the sources of uncertainty in regional warming projections in southern South America.
