Ancient Warning of a Rising Sea | Interactive – the Washington Post
By studying the long-dead coral reefs, researchers have revealed not only how high sea levels can reach, but where the deluge will hit hardest. As temperatures surge and ice sheets melt, the fossils show, the oceans won’t rise evenly around the planet. Instead, the loss of polar ice will trigger profound changes in Earth’s gravity and shape — which, in turn, will create dramatic disparities in where ocean water flows…
Melting Ice Shelves
“Together, the Antarctic and Greenland Ice Sheets contain more than 99 percent of freshwater ice on Earth. If they both completely melted, they would raise sea level by an estimated 67.4 meters (223 feet). Long-term satellite data indicate that through most of the twentieth century, the ice sheets made very little contribution to sea level, and were nearly in balance in annual snowfall gain and ice or meltwater loss. However, the stability of the ice sheets has changed considerably in the twenty-first century…” – Ice Sheets Today
Two Studies on Greenland Reveal Ominous Signs for Sea Level Rise – the New York Times
Greenland’s mountain glaciers and floating ice shelves are melting faster than they were just a few decades ago and becoming destabilized, according to two separate studies published this week. The island’s peripheral glaciers, located mostly in coastal mountains and not directly connected to the larger Greenland ice sheet, retreated twice as fast between 2000 and 2021 as they did before the turn of the century, according to a study published on Thursday. “It got a lot harder to be a glacier in Greenland in the 21st century than it had been even in the 1990s,” said Yarrow Axford, a professor of geological sciences at Northwestern University and a co-author of the paper, published in the journal Nature Climate Change…
What the Melting of Antarctic Ice Shelves Means for the Planet – Inside Climate News
Antarctica’s ice shelves are the gatekeepers between the continent’s glaciers and the open ocean. As the planet warms, these shelves shrink, exposing more and more ice, which leads to more melting. This frozen continent rests under a massive ice sheet averaging more than a mile thick. But a recent study in Science Advances found that Antarctica had 68 ice shelves that shrunk significantly between 1997 and 2021, adding up to about 8.3 trillion tons lost during that time…
West Antarctic ice sheet faces ‘unavoidable’ melting, a warning for sea level rise – the Washington Post
Accelerating ice losses are all but “unavoidable” this century in vulnerable West Antarctic ice shelves as waters warm around them, according to new research. And the analysis could mean scientists were too conservative in predicting about one to three feet of sea level rise by 2100…
Greenland’s ice shelves hold back sea level rise. There are just 5 left – the Washington Post
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…
Research Confirms Link Between Snow Crab Decline and Marine Heatwave – NOAA Fisheries
“During the marine heatwave, snow crabs faced a triple threat,” said lead author and Alaska Fisheries Science Center stock assessment scientist Cody Szuwalski. “Their metabolism increased, so they needed more food; their habitat was reduced so there was less area to forage; and crabs caught in our survey weighed less than usual. These conditions likely set them up for the dramatic decline we saw in 2021…”
