A study published in Nature on March 4, 2026, found that more than 99% of coastal hazard assessments conducted over the past 16 years used flawed sea-level data, meaning actual ocean levels are ...

Adjusting to a more accurate coastal height baseline means that if seas rise by a little more than 3 feet — as some studies suggest will happen by the end of the century — waters could inundate up to ...

Global average sea level is increasing due to melting land ice and expansion of warming seawater, both caused by global warming. Sea level has been measured regularly since the 19th century using ...

Rising seas now threaten coastal cities worldwide. A Virginia Tech report examined 32 major U.S. coastal cities using satellite data on land subsidence, sea-level-rise projections, and tide charts to ...
