Will climate change have something to say about the Tweed Airport expansion? Experts think so

The problematic climate future Tweed faces actually is possible along just about all of New Haven’s shoreline. Parts of that shoreline – including the Long Wharf area — were once under water and may be destined for it again as the entire area faces increased battering from ever more-intense and frequent storms and the highest rates of sea level rise in the in the U.S. in the last 60 years, according to multiple studies, including data from NOAA. Best case scenarios show Tweed and the New Haven shoreline to be among Connecticut’s areas most vulnerable to the rising waters from climate change. Even just the projected 20 inches of sea level rise, taking into account existing coastal protections, shows Tweed runways under water, in Climate Central’s map. Add in factors such as moderate flooding and potential storm surge, and almost the entire airport is underwater by 2050, according to the group.
