Global warming is increasing magma? Lunatic.
Which makes a lot of sense inasmuch as this happens in Eastern Lake Superior (couple of volcanoes there) every time we get an "interglacial" in the current ongoing 2 million year old Ice Age.
However, it can also be the case that an existing volcano tokes up (e.g. Iceland is a volcanic piece of the Mid-Atlantic Ridge, so it's volcanoes turn on and off all the time ~ geologically speaking). When the volcano tokes up, it heats up, and melts the ice. People say "Whoa, is that melting ice because it's warmer air, or is that melting ice because it's warmer ground?"
At the moment, to be fashionable, the Icelanders regularly interpret every irregularity in their homeland as being derived from GW.

That extra .5 degrees celsius air temperature really makes a difference under the earth’s crust.
