From Europe and India to North America and the Middle East, extreme heatwaves are pushing temperatures to dangerous new levels. Scientists say many of these events would have been nearly impossible without human-driven climate change. Cities are becoming heat traps, roads are buckling under extreme temperatures, and electricity grids are struggling to meet the rising demand for cooling.

Wildfires are also becoming more frequent and more intense, while crops are drying out faster, putting pressure on food supplies. Hospitals in many regions are seeing more heat-related illnesses every year, especially during long and repeated heatwaves that leave little time for recovery.

In some areas, even nighttime temperatures are no longer dropping enough for the human body to cool down properly. This is especially dangerous for children, older adults, and outdoor workers. Scientists also warn that hotter oceans and increasing humidity could make future heatwaves even more severe.

This is not just “summer being hot.” It is a rapidly changing climate system. Experts caution that if greenhouse gas emissions continue to rise, today’s record-breaking temperatures could become the new normal in the years ahead.
