Have you heard that the Arctic ice is melting because of Global Warming? Don't believe it. The real reason has just been discovered (and possibly the reason for "so-called" Global Warming) and they didn't even know it.

New evidence deep beneath the Arctic ice suggests a series of underwater volcanoes have erupted in violent explosions in the past decade.

Hidden 2.5 miles (4,000 meters) beneath the Arctic surface, the volcanoes are up to a mile (2,000 meters) in diameter and a few hundred yards tall. They formed along the Gakkel Ridge, a lengthy crack in the ocean crust where two rocky plates are spreading apart, pulling new melted rock to the surface.

Until now, scientists thought undersea volcanoes only dribbled lava from cracks in the seafloor. The extreme pressure from the overlying water makes it difficult for gas and magma to blast outward.

But the Gakkel Ridge, which is relatively unexplored and considered unique for its slow spreading rate, is just the place for surprises.

Robert Reeves-Sohn of the Woods Hole Oceanographic Institution (WHOI) in Massachusetts and his colleagues discovered jagged, glassy fragments of rock scattered around the volcanoes, suggesting explosive eruptions occurred between 1999 and 2001.
