Parece que se está fraguando el desprendimiento de un nuevo gran iceberg en el glaciar #Petermann (#Groenlandia). Podría producirse en los próximos días o, si la llegada del otoño lo impide, el verano que viene.
A ojo, el iceberg resultante podría tener entre 100 y 150 km2.

Glaciers Rise and Fall—and Melt—with Tides

The effect of ocean water creeping beneath Greenland ice is stronger than scientists realized.

"Using satellite measurements of its surface, researchers found that #Petermann has been bouncing up and down, dramatically shifting its #seafloor moorings in response to the tides. All this movement has carved a large cavern at the base of the #glacier and allowed warm water to regularly stretch beneath it. As the glacier lifts and migrates, the water can rush in for over a mile, thinning the ice by as much a 250 feet a year in some places."

A Greenland glacier’s rapid melting may signal faster sea level rise

Scientists studying one of Greenland’s largest glaciers say it is melting far faster than expected at its most vulnerable point, a worrying sign that glaciers perched in the ocean could contribute more rapidly to sea level rise than currently forecast.

Unexpected Melting of Greenland Glacier Could Double Sea-Level Rise Projections

The way that the Petermann Glacier in Northwest Greenland is melting indicates that current models are too conservative.

Unexpected Melting of Greenland Glacier Could Double Sea-Level Rise Projections - Alaska Native News

The way that the Petermann Glacier in Northwest Greenland is melting indicates that current models are too conservative. A glacier in the north of Greenland is melting faster and in a different way than scientists previously thought, and this has troubling implications for the future speed of global sea-level rise. The new discovery was published in the Proceedings […]
