Scientists say the answer is in the ice.

Scientists know that sea levels have risen more in some places during the past century than in others. They’ve gone up faster along the Mid-Atlantic States, particularly near Cape Hatteras and the Chesapeake Bay, compared to north along the Gulf of Maine and south along the South Atlantic Bight. But why?
“Sea-level rise affects us all,” said Chris Piecuch, assistant scientist at the Woods Hole Oceanographic Institution and lead author of a new study recently published in the journal Nature that explains the reasons for sea-level rise variations on the East Coast. “Those of us who live on the coast are feeling, and will continue, to feel more acutely its effects. But even those who don’t live on the coast will feel the effects. Going into the future, over the coming centuries, multiple meters of global sea-level rise are possible. And even if the nature of storms doesn’t change in the future, the higher ‘baseline’ of rising seas will make the impacts of coastal storms worse. Sea-level rise will come, making the bad worse.”
Piecuch and his colleagues attribute the “unequal” sea-level rise in the East to a phenomenon known as “post-glacial rebound.”Share This
