Extreme heat across Europe can bring record daytime temperatures and persistently hot nights, with risks varying across countries and populations.
Attribution research links human-caused warming to greater likelihood or severity of many heat extremes, while physical patterns such as high-pressure systems can help trap hot air over a region. Heat waves have been associated with increased mortality and pressure on hospitals, as well as rail disruption, school closures, reduced power generation, and stress on rivers and other water-dependent systems. Understanding both the climate signal and these connected impacts helps explain why heat preparedness involves health services and infrastructure as well as weather warnings.
