Deadly heatwave shatters temperature records across Europe and shifts east

A deadly heatwave linked to dozens of deaths shattered temperature records across Europe on June 27, with temperatures soaring above 40 degrees Celsius as the event moved east from Scandinavia to the Alps.

The extreme conditions, driven by an omega block phenomenon that traps hot air over regions, have damaged highways, cancelled trains, and strained hospitals.

This event strengthens the perception of urgency for fighting climate change as leaders at COP30 call for immediate global agreement.

  • The 'omega block' is a high-pressure weather pattern named for its resemblance to the Greek letter Ω (omega).
  • Switzerland recorded its hottest-ever June day for the third consecutive day in 2026.
  • Red heat alerts in Rome require tourists to seek shade and use public fountains to cool down.
