Just How Much Can We Trust A.I. to Predict Extreme Weather?

Joe Spring Associate Editor, Science The stories on artificial intelligence’s improving ability to predict extreme weather often begin with powerful hurricanes. As Scientific American detailed this year, when Hurricane Lee was moving through the Atlantic Ocean last September, scientists using traditional weather models got a clear idea of where the hurricane would go just six […]
