As climate change pushes sea levels up, Massachusetts’ southern coast will more regularly be pummeled by storms and face catastrophic flooding and increased erosion. That’s according to a new report from the conservation group Trustees of Reservations.

The analysis says sea levels along the South Coast could, by 2050, rise by over two feet. Towns around Buzzards Bay and Narraganset Bay are especially at risk.

These maps from the Trustees of Reservations illustrate that grim future.
