Greenland’s ice shelves hold back sea level rise. There are just 5 left – the Washington Post

Ice accelerating as it flows towards the coast creates heavy crevassing near the coast of Melville Bay in west Greenland (by John Sonntag/NASA’s Operation IceBridge courtesy of NASA Earth Observatory, public domain).

And now there are only five large shelves left, stretching out from their fjords toward the Greenland Sea and the Arctic Ocean. That includes three major ones — Petermann, Ryder and Nioghalvfjerdsbrae (often referred to as 79 North for its location in degrees latitude) — whose respective glaciers could ultimately account for 3.6 feet of sea level rise if they were to melt entirely — a process that would take centuries to play out…

Multiple new studies highlight a rate of sea level rise that is ‘unprecedented in at least 120 years’ along the Gulf of Mexico and southeastern U.S. coast.

Scientists have documented an abnormal and dramatic surge in sea levels along the U.S. gulf and southeastern coastlines since about 2010, raising new questions about whether New Orleans, Miami, Houston and other coastal communities might be even more at risk from rising seas than once predicted…
