Antarctica is leaking from the inside out

The Antarctic Ice Sheet is draining huge quantities of water out to sea.
By Jeremy Deaton Nexus Media Yesterday at 2:19pm
 

When climate scientists look at Antarctica, they see a ticking time bomb. If the ice sheet melts, it will raise sea levels by tens of feet, flooding coastal cities around the globe.

For now, the southern continent is relatively stable, but it’s starting to look more like Greenland, where rising temperatures are melting the island from the inside out.

Abraham Lincoln:

There is no grievance that is a fit object of redress by mob law.
--January 27, 1838 Lyceum Address

Don't interfere with anything in the Constitution. That must be maintained, for it is the only safeguard of our liberties. And not to Democrats alone do I make this appeal, but to all who love these
great and true principles.
--August 27, 1856 Speech at Kalamazoo, Michigan

Let us then turn this government back into the channel in which the framers of the Constitution originally placed it.
--July 10, 1858 Speech at Chicago

If those temperature rises are melting the ice from the inside, then the heat source is below the ice, not above it. No amount of driving small cars stops volcanic activity.

Seems like we might at some point have a whole new continent to populate, grow vegetables on and herd cattle.

Just another scare story from the warmistas trying to hold onto their government funding.

Nope.

The melting is occurring at the plan-view interior of the ice sheet because rising temperatures have shifted the ablation/melting zone farther inland.  This increased melting at the cross-sectional surface infiltrates through the glacier, transporting heat to the interior (plan and cross-sectional) of the glacier, most critically to the bed.   At the bed, it "lubricates" (porewater pressure increases), which increases the flowrate.

If the ocean is simultaneously warming, that will cause melting from beneath the buyoant, ungrounded ice and float it, which will move the grounding line landward, which leads to even more buoyancy.  Ice flow will increase, which can cause the ice sheet to expand, although it can also result in a collapse, as the unsupported ice can more easily calve.

Link a map if you would. Melting at the surface in the interior of a polar continental climate would almost certainly be related to volcanic activity beneath. Antarctica is not noted for its warm weather, especially above 32F.

The real problem is not whether or not the climate is warming/changing, but whether human activity is causing that warming/change.  There is reasonable evidence that the climate is warming/changing, but there is not much that human activity is causing, or is even primarily responsible for, this warming/change.

And it is only that causal link that can justify the fascism of the eco-freaks.  The mere fact that the climate may be warming/changing does not.

The problem in science is when supposition is taken as proof.  Yes, it COULD happen that way.  Now prove that it is.

AND DO NOT use the results from a computer model to try proving it. Show me real world data that proves the average temperature in the Antarctic interior is above freezing, and staying above freezing long enough to allow meltwater to run freely along the surface all the way to the ocean.

Yup, a computer model is just a high-tech crystal ball.  Without the complete data set to compare against, proving every assumption the model makes, it just shows the user what he wants to see.

One does not need proof the climate is changing.  It is now, has been, and always will be.

And exactly who is to say it is not changing for the better anyway?

Exactly, and as Jerry Pournelle has pointed out, a generally warm climate is MUCH better for humanity than a generally cold one.

Hey! This is a continent, it isn't like we're discussing some little island like Guam... :silly:
