South Korea has recorded the hottest day in its national weather history, setting a new temperature mark during an intense heatwave. The record is especially notable because the country’s official weather observations stretch back more than a century.

The new high comes as extreme heat grips South Korea and adds to a broader pattern of severe weather seen around the world this year. The latest milestone shows how temperature records are continuing to fall as many regions face unusually intense conditions.

Scientists say the climate crisis, driven by human activity, is making heatwaves more frequent. As global temperatures rise, the likelihood of prolonged and record-breaking heat also increases, turning what once were rarer events into a more regular threat.

South Korea’s latest record highlights how countries are being pushed by worsening heat extremes at the same time that other parts of the world are also dealing with volatile weather. It is another sign of how climate-related extremes are becoming a defining feature of the global environment.
