I don't think Smallax was implying they were necessarily responsible for Global Warming. I think he was implying they are responsible for contributing to melting the Ice shelfs above them as they warm the water below. Here's an excerpt and the photo:

There’s an active volcano under Antarctic ice Watts Up With That?
Yet many claim the CO2 is the driver for any melting of the Antarctic ice sheet. I wonder how this will figure into that argument?
Larsen Ice Shelves A and B, by the way, sit astride a chain of volcanic vent islands known as the Seal Nunataks, which may figure into melting and breakups like this and this. (h/t Alan)
In fact, there are a LOT of volcanoes in Antarctica as you can see in this image. Notice that many are near the edge of the ice, and there are none in the interior, which may be a lack of discovery of ancient ice buried volcanoes. Most scientific bases are near the sea, rather than inland, for supply and weather tolerance purposes and there are many places in the interior that have yet to be fully explored.
These images showing known Antarctic volcanoes and satellite measured temperature trends from 1992-2004 below tends to back up the idea that where there is volcanic activity, temperatures have been rising.
The first evidence of a volcanic eruption from beneath Antarctica’s ice sheet has been discovered by members of the British Antarctic Survey.
The volcano on the West Antarctic Ice Sheet began erupting some 2,000 years ago and remains active to this day. Using airborne ice-sounding radar, scientists discovered a layer of ash produced by a ’subglacial’ volcano. It extends across an area larger than Wales. The volcano is located beneath the West Antarctic ice sheet in the Hudson Mountains at latitude 74.6°South, longitude 97°West.
