Greenland fossil discovery reveals increased risk of sea-level catastrophe | ScienceDailyhttps://www.sciencedaily.com/releases/2024/08/240805164411.htmA new study provides the first direct evidence that the center -- not just the edges -- of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape.

"This new study confirms and extends that a lot of sea-level rise occurred at a time when causes of warming were not especially extreme," said Richard Alley, a leading climate scientist at Penn State who reviewed the new research, "providing a warning of what damages we might cause if we continue to warm the climate."

Sea level today is rising more than an inch each decade. "And it's getting faster and faster," said Bierman. It is likely to be several feet higher by the end of this century, when today's children are grandparents. And if the release of greenhouse gases -- from burning fossil fuels -- is not radically reduced, he said, the near complete melting of Greenland's ice over the next centuries to a few millennia would lead to some 23 feet of sea level rise.
"Look at Boston, New York, Miami, Mumbai or pick your coastal city around the world, and add twenty plus feet of sea level," said Bierman. "It goes underwater. Don't buy a beach house."
