Increased precipitation resulting partially from climate change has caused an additional $2.5 billion a year in U.S. flood damage, according to a new study that pinpoints the effect of changing weather on the cost of natural disasters.

A study published yesterday in the Proceedings of the National Academy of Sciences journal says that from 1988 through 2017, intensifying precipitation was responsible for a total of $75 billion in U.S. flood damage over the 29-year study period. Total flood damage in those years was nearly $200 billion, meaning that the excess precipitation accounted for more than a third of the damage in that period.
