Volcanoes Under The Arctic Ice May Be Behind The Ice Melts Of The Northern Hemisphere

But don’t expect Al Gore or any of the Global Warming alarmists to be talking about it. In fact, it is probably in their best financial interest to try and hide it.

But, what is even more important is that this may be the explanantion as to why the Arctic Ice retreated recently (and then came back) while Antarctic Ice seems to be getting thicker and growing.

Take a look at this from Yahoo News:

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.

[W]hen 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.

Previous research had concluded that this kind of so-called pyroclastic eruption could not happen at such depths due to the crushing pressure of the water.

Which is why no one considered the possibility that a volcanic eruption under the ice pack may have greatly contributed to the melt-off. Certainly, Al Gore’s trained parrot “scientists” never thought about it.

So, what does all of this really mean? It means that man-made global warming just took another major blow to the head. The next logical question to ask is: Is there any evidence that volcanoes are having an effect on ice melts in the northern hemisphere? And, could this be the reason why ice melts are happening in the northern hemisphere despite declining global temperatures while the ice in the southern hemisphere is getting thicker?

We can look to the Ohio State University for an answer to that one:

Scientists have discovered what they think may be another reason why Greenland ‘s ice is melting: a thin spot in Earth’s crust is enabling underground magma to heat the ice.

“The behavior of the great ice sheets is an important barometer of global climate change,” said Ralph von Frese, leader of the project and a professor of earth sciences at Ohio State University. “However, to effectively separate and quantify human impacts on climate change, we must understand the natural impacts, too.

And it is these “natural impacts” that Al Gore and the global warming alarmists have been completely ignoring.

von Frese’s team combined gravity measurements of the area taken by a Naval Research Laboratory aircraft with airborne radar measurements taken by research partners at the University of Kansas. The combined map revealed changes in mass beneath the Earth’s crust, and the topography of the crust where it meets the ice sheet.

Below the crust is the mantle, the partially molten rocky layer that surrounds the Earth’s core. The crust varies in thickness, but is usually tens of miles thick. Even so, the mantle is so hot that temperatures just a few miles deep in the crust reach hundreds of degrees Fahrenheit, von Frese explained.

“Where the crust is thicker, things are cooler, and where it’s thinner, things are warmer. And under a big place like Greenland or Antarctica , natural variations in the crust will make some parts of the ice sheet warmer than others,” he said.

The ice thickness, the temperature at the base of the ice, and ground topography all contribute to the forming of an ice stream — a river of ice that flows within a larger ice sheet. In recent years, Greenland ice streams have been carrying ice out to sea faster, and ice cover on the island has been diminishing.

The newly discovered hotspot is just below the ice stream, and could have caused it to form, the researchers concluded. But what caused the hotspot to form?

“It could be that there’s a volcano down there,” he said. “But we think it’s probably just the way the heat is being distributed by the rock topography at the base of the ice.”

So, scientists are finally acknowledging what we skeptics have been saying for years: The issue is a hell of alot more complex than just human actvity and it is looking like nature is playing a larger role than humans could ever hope to.

Thus far, there are no hotspots or volcanoes being reported in Antarctica where the ice is getting thicker.
