An SUV is stuck in the sand on N.C. 12 in the Mirlo Beach area of Rodanthe, N.C. on Thursday, March 7, the day after a winter storm brought soundside flooding and some ocean overwash to Hatteras Island.

QUOGUE, N.Y.

As the president of the Fire Island Association, Suzy Goldhirsch has a message she says she often offers property owners.

“We are living on a sandbar in the middle of the Atlantic Ocean,” she tells them. “We are in a high-risk environment. We on barrier islands are on the front lines of climate change.”

The same could be said of many coastal areas around the world, which are threatened by rising sea levels as the planet warms. But the barrier islands that line the Atlantic and Gulf Coasts, from Cape Cod to the Mexican border, are a special case.

A new report from the National Research Council finds that the effect of climate change is especially harsh on these islands. Population growth in much of this long coast “is nearly twice the national average,” the report said. Meanwhile, “these same coasts are subject to impact by some of the most powerful storms on earth and the destruction potential of these events is increasing due to climate change and relative sea-level rise.”
