Reply to comment by clampie in Greenland's glaciers are melting 100 times faster than estimated by strangeattractors

Volcanic activity is not a significant cause of glacial loss in the Antarctic, there are no active volcanoes at all in Greenland.

The volcanoes are doing everything bad myth comes from a cult started by a Ukranian chiropractor and is funded by a bunch of right wing think tanks.

Underground activity is important. Japanese researchers discovered major plumes under Greenland in 2020.

- A hot plume (Greenland plume) rising from the core-mantle boundary beneath central Greenland is discovered.

- The Iceland and Greenland plumes are connected and supplying magmas to Iceland, Jan Mayen, and Svalbard hotspots.

That plume has existed for millions of years. It's cooling.

In fact, that very research you cited even states that the heat from the plume is feeding the Iceland plume, which is why Iceland has over 100 volcanoes, and over a third of them are active volcanoes (have erupted in the part 50,000 years). Greenland has no active volcanoes at all.

Volcanic activity and heat plumes function over geological time scales. That plume under Greenland was hotter when the ice formed than it is today.

We just learned about it. And it creates hot spots. lol

We've known that there was a hot spot under Greenland for a very long time. We didn't know that it was still active, which is what the research you're citing confirms.

No, we didn't know.

If it's hot enough to melt rocks, it's hot enough to melt ice.

The researchers didn't show up and discover nothing.

If we didn't know, how did the page I linked to, published before your paper, talk about a hot spot in Greenland?
