Hmm, I wonder
Interesting news:PARIS (AFP) - Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea, scientists who filmed the aftermath reported Wednesday.

The eruptions -- as big as the one that buried Pompei -- took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking 1,800 kilometres (1,100 miles) from the northern tip of Greenland to Siberia.
Scientists suspected even at the time that a simultaneous series of earthquakes were linked to these volcanic spasms.
But when a team led of scientists led by Robert Sohn of the Woods Hole Oceanographic Institution in Massachusetts finally got a first-ever glimpse of the ocean floor 4,000 meters (13,000 feet) beneath the Arctic pack ice, they were astonished.
What they saw was unmistakable evidence of explosive eruptions rather than the gradual secretion of lava bubbling up from Earth's mantle onto the ocean floor.
Now, let's try a thought experiment. We've been hearing a lot in the news about Artic polar ice melting (the news, for some reason, hasn't covered the thinkening of the Antartic ice nearly as much). So, I wonder: what's more likely to cause the ice at one, and only one, polar ice cap to melt?
A: Global Warming
B: Active volcanos under the melting ice cap
Just curious.
