Lancet Report Declares Climate Change a Global Health Emergency, Citing Accelerating Health Harms

The 10th annual Lancet Countdown report urges that climate change be formally recognized as a global health emergency, emphasizing that its health impacts are accelerating faster than the world's response. The report, a collaboration of 146 researchers from over 100 institutions, highlights that heat was linked to a record 710,000 deaths in 2023, with over 70% attributed to human-caused climate change. It also notes that more than half the world's land experienced extreme drought for at least a month in 2025.
