At the top of the world, northern Greenland’s huge glaciers — long thought to be relatively stable — are in trouble, a new study shows.

As the ocean warms, Greenland’s last remaining ice shelves are rapidly weakening, destabilizing the nearby glaciers and threatening potentially “dramatic” consequences for sea level rise, according to the study published Tuesday in Nature Communications.

Ice shelves are tongues of floating ice that jut out over the ocean and act as dams that hold back glaciers on land and slow ice loss. When they melt and weaken, more of the land-based ice is able to slide into the ocean, adding to sea level rise.

This is the best summary I could come up with:

At the top of the world, northern Greenland’s huge glaciers — long thought to be relatively stable — are in trouble, a new study shows.

“These glaciers are among the most important of the ice sheet,” Romain Millan, a glaciologist at the Grenoble Alpes University in France and an author of the study, told CNN.

Millan and his co-authors used thousands of satellite images, along with climate models and measurements from the field, to better understand the drivers for — and timing of — historical and current changes to the ice shelves.

The report calls for continued monitoring to better asses how the ice shelves will respond to climate change and, in particular, to build on the study’s findings about the complex process of basal melting and the potential impacts on sea level rise.

“We knew that ice shelf basal melting is related to ocean temperature, but what is neat about this study is that it gives a better idea about the timing and magnitude of the change.”

The original article contains 905 words, the summary contains 201 words. Saved 78%. I'm a bot and I'm open source!

“Iceland is green, Greenland is icy.” Oh, shit, it’s also the biggest island that’s not a continent.

Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
