Heat Dome Brings Record Temperatures Across Europe

Extreme heat is sweeping across Europe, with millions of residents operating under heat alerts as temperatures climb to record levels.

Metorologists have identified a ridge of high pressure—known as a heat dome—as the primary driver of the conditions. The system traps hot air moving northward from North Africa, preventing typical weather patterns from dispersing the warmth across the continent.

Climate scientists have connected the frequency and intensity of such extreme heat events to human-driven climate change. Researchers studying long-term temperature trends find that greenhouse gas emissions are altering atmospheric conditions in ways that make prolonged heat waves more common and more severe than historical patterns would suggest.

The ongoing event has prompted meteorological agencies across multiple European nations to issue heat alerts warning residents of dangerous conditions. Health officials typically recommend limiting outdoor exposure during peak heat hours, staying hydrated, and checking on vulnerable populations during such events.

NBC News meteorologist Molly Hunter reported on the developing situation for the TODAY show, noting the scale of the affected population and the meteorological factors contributing to the heat dome's formation.
