Five years after Hurricane Sandy, a Climate Central sea level rise analysis outlines the U.S. populations most at risk from coastal flooding now and by mid-century.
The frequency of high streamflows has risen over the past 30 years in the Northeast, Ohio Valley, and the Mississippi Valley.
A new Climate Central analysis shows an upward trend in the number of heavy precipitation events in the vast majority of the Lower 48 states since 1950.
See where climate change is affecting U.S. coastal flooding the most.
Our report examined intensity and duration of the heaviest runoff events for each state.
Each state receives a conventional letter grade to illustrate its climate change preparedness overall and for five specific hazards: heat, drought, wildfires, inland & coastal flooding.
Since 1900, the average annual precipitation is up 5 percent for the continental U.S.
Heavy downpours have increased in every region of the contiguous states since 1950.
