Hurricanes are among the most dramatic examples of extreme weather. And with climate change making tropical cyclones ever more intense, some scientists are arguing that the way we categorise them doesn’t sufficiently describe how dangerous these storms can be.

They examine how hurricanes are classified, and ask if we need to find more efficient methods of saving lives.The Global Story brings you trusted insights from BBC journalists worldwide.
