I've been posting versions of this warning for years:
Then-Milwaukee Mayor John Norquist and I attended a conference in Chicago in 2003, hosted by Mayor Richard Daley, where officials from the [George W. Bush-era] EPA told Midwestern elected leaders that climate change models predicted heavier rain events.
The EPA officials were urging the Midwestern leaders to adapt their planning and spending to more aggressively confront storm water and related services because heavier, intense rains were going to be come more frequent.
