"Disturbing" discovery: Giant hole found under Antarctica glacier

Researchers say a massive cavity the size of two-thirds of Manhattan was found under a glacier in Antarctica. The pocket is a sign of "rapid decay" and just one of "several disturbing discoveries" made recently regarding the glacier, NASA's Jet Propulsion Laboratory said in a news release Wednesday.

"[The size of] a cavity under a glacier plays an important role in melting," said Pietro Milillo of the Jet Propulsion Laboratory. "As more heat and water get under the glacier, it melts faster."

The growing cavity sits in West Antarctica at the bottom of Thwaites Glacier, which is about as big as Florida and contains enough ice to contribute more than 2 feet to sea level rise, NASA said. It is growing at an "explosive" rate that surprised researchers conducting a study the agency led on the glacier.

That doesn’t sound right. The earth’s core has no fuel.

See below ...

The flow of heat from Earth’s interior to the surface is estimated at terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth.

There's your fuel. Nuclear fuel.

Advances in imaging technology allowed us to learn that Antarctica is the most volcanic continent on the planet.
If there is a hole, it could be from seismic activity, a volcano that collapsed on itself or other issues.

The greatest concentration of volcanoes has been found in Antarctica—and that’s terrifying news

Interestingly, this also means that many of the “OMG, the glaciers are melting and moving” is more because the liquid mud and lave underneath are the blame - not the atmosphere.

"Does this have anything to do with the Paris Climate Treaty>"

Yup. Proves that Trump is a danger to the whole world.

I guess it depends on the use of ‘interior.’
The core, to me, is the interior. The mantle and crust are like the skin of an orange, not its interior. But words are elastic and I won’t argue the point.

Glaciers are sold by weight, not by volume.

That glacier's gonna need a filling. And probably a crown.

Is anybody here a glacier dentist? Tim Whatley? John Voight?

It’s them damn illegals. They’ll tunnel anywhere.

Ok. Ping to #97.

Also, I’m talking average thickness. I wonder how flat the earth underneath it is. Possibly over 7k in places. Hard to imagine without actually going there. An alien world to a guy like me, that’s only ventured outside of the USA a couple of times (about 75 miles into Canada, and to a couple of the Bahama islands).

I read the article to find the “terrifying news.” They save that for the end, where they reveal that last month (the article was published in 2017), an iceberg broke off Antarctica that was “60 times the size of Paris,” which, at 41 square miles, is 1/132800 the size of Antarctica, so the iceberg was 1/2213, or 0.045% the size of Antarctica.

Area of Manhattan vs area of Antarctica:

22.8 sq mi / 5,400,000 sq mi = 0.00000422 = not worried yet

Just curious, but if the ice melted off of both Polar Caps, would it all pour into the sea to flood the coasts of the earth? Or would it evaporate and maybe even water the deserts again?

I'm certain all those special scientific models cover this.

now that the billionaires have sold all their ozone, they needed new gases..law needed to sell other propellants..hoax
i worked at nasa during that time, ozone hole was closing when they made it illegal

The mantle is definitely part of the interior by logical definition. It is beneath the crust which is 25-62 miles thick.

But if it's the core you want to talk about it's also hot due to radioactive decay. Hotter than the mantle. And not just the outer core but the inner core as well.

5 Facts About the Earth's Inner Core

The temperature of the inner core is estimated to be between 3,000 and 5,000 Kelvins (4,940 to 8,540 degrees Fahrenheit). The high temperature comes from three main sources. There is residual heat left from the Earth's formation, and heat is generated by gravitational forces from the sun and moon as they tug and pull on the inner core. Finally, the radioactive decay of elements deep within the Earth also produces heat.

Please join me in a moment of angst.

Thank you. Resume your normal lives.

Or, to us mathematically challenged, less than the amount of Injun DNA in Feuxahontis.

>>>What ever happened to that giant hole in the ozone over Antarctica?

The size has gotten smaller as the use of CFCs has been phased out.
