Could Volcanoes Be Melting The Arctic Ice?

Volcanic eruptions reshape Arctic ocean floor: study

Wed Jun 25

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

The mid-ocean ridge runs 84,000 kilometres (52,000 miles) beneath all the world’s major seas except the Southern Ocean, and marks the boundary between many of the tectonic plates that make up the surface of the Earth.

When continental plates collide into each other, they can thrust up mountain ranges such as the Himalayas.

But along most of the mid-ocean ridge — including the Gakkal Ridge — the plates are pulling apart, allowing molten magna and gases trapped beneath the crust to escape

Both sonar and visual images showed an ocean valley filled with flat-topped volcanos up to two kilometres (1.2 miles) wide and several hundred metres high.

Er, is it not possible that these volcanic eruptions — going back to at least 1999 — may have played a part in whatever melting there has been of the Greenland and Arctic ice sheets?

If there has even been any.

For according to the global warming cultists scientists at NOAA’s Geophysical Fluid Dynamics Laboratory, the amount in ice began to decline precipitously in around 1999, which is when these volcanoes began their eruption.

But isn’t it funny how not one word about the purported simultaneous decline in arctic ice was ever mentioned in the original article?

Why do you suppose that is?
