Ocean heatwaves are hiding months of extra warming
Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on average, potentially overlooking a major source of stress on marine ecosystems.

Heatwaves, wildfires expose a third of world to extreme ozone pollution
Heatwaves and wildfires helped expose 34 percent of the world’s population to “extremely poor” ozone air quality in the first eight months of 2026, according to a European Union report published Wednesday. Asia recorded the highest exposure, while ozone pollution remained difficult to curb despite decades of progress in reducing other harmful emissions.
