Sea level rise driven by climate change is set to pose an existential crisis to many US coastal communities, with new research finding that as many as 311,000 homes face being flooded every two weeks within the next 30 years.
The swelling oceans are forecast repeatedly to soak coastal residences collectively worth $120bn by 2045 if greenhouse gas emissions aren’t severely curtailed, experts warn. This will potentially inflict a huge financial and emotional toll on the half million Americans who live in the properties at risk of having their basements, backyards, garages or living rooms inundated every other week.
“The impact could well be staggering,” said Kristina Dahl, a senior climate scientist at the Union of Concerned Scientists (UCS). “This level of flooding would be a tipping point where people in these communities would think it’s unsustainable.
The UCS used federal data from a high sea level rise scenario projected by the National Oceanic and Atmospheric Administration, and combined it with property data from the online real estate company Zillow to quantify the level of risk across the lower 48 states.
