The Mediterranean Sea experienced a record-breaking heatwave in summer 2025. We compared this event to similar patterns from past decades to see how a warmer climate changed its strength. We found that today's warmer background added about 1.5 °C to the sea surface, making the heatwave far more intense and widespread. This shows how climate change is turning ordinary weather patterns into extreme events, with major impacts on marine life, coastal communities, and economies.

Storm Daniel (2023) is one of the most catastrophic storms ever documented in the Mediterranean. Our results highlight the different dynamics and therefore the different predictability skill of precipitation, its extremes and impacts that have been produced in Greece and Libya, the two most affected countries. Our approach concerns an analysis of the storm by articulating dynamics, weather prediction, hydrological and oceanographic implications, climate extremes, and attribution theory.

Tracking tropical cyclones (TCs) remains a matter of interest for investigating observed and simulated tropical cyclones. In this study, Random Forest (RF), a machine learning approach, is considered to track TCs. RF associates the TC occurrence or absence with different atmospheric configurations. Compared to trackers found in the literature, it shows similar performance for tracking TCs, better control over false alarms, more flexibility, and reveals key variables for TCs' detection.

Extreme weather events pose increasing challenges for aviation, including flight disruptions and infrastructure damage. This study examines the influence of anthropogenic climate change on four recent major storms across Europe, the USA, and East Asia. Our research underscores the growing intensity of extreme storms, driven by human-induced climate change, stressing the need to adapt aviation strategies to an increasingly hazardous environment.

Cold spells affect healthcare and energy systems. Global warming is expected to reduce the amplitude and frequency of these climate extremes. We show that the intense cold spells of the 20th century will become nearly impossible in France by the end of the 21st century for high warming levels. We also demonstrate that events in France as intense as that in 1985 may still occur in the near future. These events are linked to specific atmospheric patterns that bring cold air from high latitudes into Europe.
