Rising Frequency of Extreme Rainfall in the US Threatens Cities.

New data from the nonprofit First Street Foundation shows that climate change is causing more devastating rains and flooding in parts of the United States. The group's peer-reviewed model reveals that the US government's current precipitation frequency estimates do not fully capture the frequency and severity of extreme precipitation in a changing climate. The study shows that what qualifies as a "1-in-100 year storm" is already happening more often in some places. The warming atmosphere is supercharging various weather-related disasters, including extreme rainfall, which poses serious challenges in a nation where aging infrastructure is increasingly outmatched.
