Northeastern US states, including Connecticut, New York, and New Jersey, are facing a new reality where extreme floods caused by hurricanes may become annual events within the next 75 years. A study published in Earth’s Future found that rising sea levels and storm surges from hurricanes will bring more frequent extreme flooding to the region.
The researchers used a computer model to predict the risk of flooding under different carbon emission scenarios. They found that historical 100-year coastal flooding could happen every year by the end of the century, while historical 500-year floods may occur every 1 to 60 years or even less often in areas with higher emissions.
Sea level rise is expected to be a major driver of increased flood risk in more northern areas like Connecticut and New York, while storm changes will play a significant role in southern regions like New Jersey. Even smaller storms could cause extensive flooding due to the impact of sea levels rising, making adaptation essential for communities near the coast.
Experts emphasize that updating building codes and moving up and back to higher ground are crucial measures to prepare for this new reality. However, not all communities will be willing or able to adapt, highlighting the need for ongoing research and support to address climate change-related risks.
