A recent study published in Nature Climate Change has found that the East Coast of the United States is particularly vulnerable to sea level rise. Compared to the global average, the study by Sallenger et al asserts that the coastline from Massachusetts to North Carolina is set to experience a rise in sea level that is “3–4 times higher…” Given the prevalence of key commercial centers along the East Coast, as well as critical naval installations (such as at Norfolk, Virginia), these projections are worrying, to say the least.
