Researchers identified 5,500 sites that store, emit or handle sewage, trash, oil, gas and other hazards that could face coastal flooding by 2100, with much of the risk already locked in due to past emissions. But more than half the sites are projected to face flood risk much sooner, some as soon as 2050.

Low-income, communities of color and other marginalized groups are the most at risk.

With even moderate reductions to planet-warming emissions, researchers also determined that roughly 300 fewer sites would be at risk by the end of the century.

Moreover, when sea water temperature increase, the cooling capacity of the nuclear reactor systems are reduced. Several US nuclear reactors are situated on the coast, including two on Florida's Atlantic seaboard, one not far from Mar-a-Lago.
