A powerful volcano erupted under the icesheet of Antarctica around 2,000 years ago and it might still be active today, a finding which raises questions about ice loss from the white continent.... The eruption occurred close to the massive Pine Island Glacier, an area where movement of glacial ice towards the sea has been accelerating alarmingly in recent decades.
“It may be possible that heat from the volcano has caused some of that acceleration,” said co-author David Vaughan, who stresses though that global warming is by far still the most likely culprit.
But of course. Meanwhile most of Antarctica has in fact cooled, and southern hemisphere ice cover has been at record highs.
