A new study points a finger at fossil fuel emissions for worsening last week's brutal European heat wave, connecting it directly to around 1,500 deaths. Researchers say climate change turbocharged the extreme temperatures, making the event deadlier than it would’ve been otherwise.

Editor’s Note: Heat waves aren’t just bad luck—they’re getting more intense because of human activity. This isn’t just about discomfort; it’s a life-or-death issue, and these findings add hard numbers to the growing urgency for climate action. If emissions keep rising, so will the body count.
