Last summer, when floodwaters nearly wiped out Old Ellicott City, many people looked at the damage as bad luck caused by a 500-year storm. The truth is that such storms are no longer rare events. The Northeast United States has experienced a staggering 70 percent increase in intense rainstorms thanks to climate change. Unfortunately, efforts in the Chesapeake Bay region to adapt policies to address these threats are lagging far behind, and without broad and meaningful action, more property damage, injuries and loss of life are likely. Heavier and more frequent rains, among other impacts of climate change, also pose a threat to the massive effort to clean up the bay.
