Europe is facing extreme autumn weather, with severe floods striking Valencia, Spain, in October. The floods caused major disruptions, flooding homes, damaging transportation, and scattering vehicles along the coastline. Reports indicate that over 95 people were directly affected. Meanwhile, the United States experienced a “flash drought” due to extremely dry conditions this month. Climate scientists highlight rising air temperatures, which increase atmospheric moisture, and shifting jet streams as key factors behind these events. In Spain, the Depresión Aislada en Niveles Altos (DANAs) phenomenon may have intensified the flooding in Valencia. This weather system traps moist air, resulting in prolonged rainfall. Meteorologist Jennifer Francis from the Woodwell Climate Research Center explains that a warming Arctic is impacting temperature balance between high and mid-latitudes, causing instability in the jet stream. Additionally, warmer sea temperatures in the Mediterranean this past summer raised humidity, leading to intense rainfall. Experts largely agree that human-driven climate change is making extreme weather events more severe.
