Along California’s 1,000‑mile shoreline, a new generation of maps is turning an abstract climate threat into something uncomfortably specific: street‑by‑street projections of which neighborhoods could ...

Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice ...

Fossil coral exposed in a limestone outcrop above present sea level in the Seychelles. Newly uncovered evidence from fossil corals suggests that sea levels could rise even more steeply in our warming ...

Ancient shorelines, buried peat and rocks locked beneath Greenland’s ice are all pointing in the same direction: when the climate warms, seas do not just creep higher, they can lurch upward. The ...

Researchers have released their 2024 U.S. sea level 'report cards,' providing updated analyses of sea level trends and projections for 36 coastal communities. Encompassing 55 years of historical data ...

Ancient coral fossils from the remote Seychelles islands have unveiled a dramatic warning for our future—sea levels can rise in sudden, sharp bursts even when global temperatures stay steady. Coastal ...

Sea-level rise threatens deltas worldwide, requiring adaptation to flood risks. Delta adaptation is typically presented as a choice between five strategies: advance, protect-closed, protect-open, ...

Coastal planning, mitigation and adaptation efforts rely on credible sea-level projections generated by physical models. However, the large uncertainties in these projections pose a challenge for ...

Sea levels along the world’s coastlines are much higher than previously assumed, more than 3 feet in some regions, according to new research, raising alarms that the world is underestimating the ...

According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems ...

When polar ice sheets melt, the effects ripple across the world. The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. But ...
