The Smithsonian has an interesting article on artifacts and bodies emerging from melting glaciers.

As Glaciers Retreat, They Give up the Bodies and Artifacts They Swallowed

Now, thanks largely to decades of global warming, the Presena glacier running through the battleground is slowly melting away. And with that melting the remains of the White War are slowly emerging. Remarkably well-kept artifacts have been streaming down with the melting water of the glacier since the early 90s

They don’t seem to get it. Just like the P-38s on Greenland , for something to emerge from the ice would imply to me that things are returning to where they were when the artifacts/bodies were deposited on the ice.

Artifacts and bodies ended up on the ice. Snow fell. The snow turned to ice and entombed the artifacts. After 100 or 5,000 years it is now as warm as it was long ago.

During the MWP Glaciers In the Antarctica Retreated Further and Faster Than Today

This paper found evidence of a MWP in Antarctica during the period 1050AD to 1200AD .The glaciers had melted even more than they have now.

The LIA returned starting around 1350AD and continued until around 1700AD.

The MWP rate of glacial retreat was faster than the present. They think more snow fell in the present slowing the retreat.

Here, we present evidence for glacial retreat corresponding to the MWP and a subsequent LIA advance at Rothera Point (67°34′S; 68°07′W) in Marguerite Bay, western Antarctic Peninsula. Deglaciation started at ca. 961–800 cal. yr BP or before, reaching a position similar to or even more withdrawn than the current state, with the subsequent period of glacial advance commencing between 671 and 558 cal. yr BP and continuing at least until 490–317 cal. yr BP. Based on new radiocarbon dates, during the MWP, the rate of glacier retreat was 1.6 m yr−1, which is comparable with recently observed rates (~0.6 m yr−1between 1993 and 2011 and 1.4 m yr−1 between 2005 and 2011). Moreover, despite the recent air warming rate being higher, the glacial retreat rate during the MWP was similar to the present, suggesting that increased snow accumulation in recent decades may have counterbalanced the higher warming rate.
