I read the Guardian article from your link. It does connect human caused global warming to more active under ice volcanoes because the thinning ice is relieving the pressure on the volcanoes. Also there is nothing in that article about under ice volcanoes creating large holes underneath glaciers.

@kmdskit3 ,
the thinning ice is relieving pressure on the volcanoes??
if there is a tremendous amount of heat escaping from a volcano under an ice shelf you don't think that would melt a hole under it?

@callmedubious Again, what you're saying is not in the article you linked to. In fact, as I said in my original comment, the article directly contradicts what you've said.

Hidden Volcanoes Melt Antarctic Glaciers from Below

Using data from airborne radar, the researchers were able to figure out where these subglacial streams were too full to be explained by flow from upstream. The swollen streams revealed spots of unusually high melt, Schroeder said. Next, the researchers checked out the subglacial geology in the region and found that fast-melting spots were disproportionately clustered near confirmed West Antarctic volcanoes, suspected volcanoes or other presumed hotspots.

@callmedubious Now you've given some evidence that volcanism under glaciers is contributing to the loss of ice in Antarctica. However in this new article it still says this is a very complex dynamic and:
"West Antarctica is also hemorrhaging ice due to climate change..."
So yes volcanism and humans are contributing to this catastrophe.
