I understand that there is increasing ice in some areas of Antarctica, although I think there was a net decrease in the volume... I was also thinking of Greenland, which is apparently losing ice at a great rate.

All icy regions are loosing ice mass / density.
You can't see it looking at it but the large holes with mile deep water falls flowing into massive melt water lakes underneath should be causing alarm globally. Sadly no one is understanding what it means and the effects it can have.

There are scars all over Canada and northern US. Geology studies have shown conclusively what these things can do. 100kl scars several stories high where ice flowed over at great speed carrying a few mountains with it.

Roll the dice, be a politician, prove science wrong with the stroke of a pen.


Make a lake of ice in a pan 20 inches thick.

Melt the top and form a cascade in the middle.

Add more volume as snow and rain and allow that too to fill the growing under ice lake.

What happens? What has to happen?

The volume of water grows, meets the ice above. The ice is then pushing against the water like a plug.
Water cannot be compressed, only squeezed.
Eventually the ice will
1 float and break apart
2 float and do nothing

The water will
1 Remain inert and do nothing
2 Press through rocks until it finds weakness.

A weakness is found the water will
1 Trickle out slowly
2 refreeze on the opening vent and back into the cavity

The refreeze will
1 do nothing
2 force the rocks apart

the rocks forcing apart will
1 drain the lake slowly
2 collapse catastrophically.

These scars would presumably indicate that this has happened before? Probably a great many times over the millions of years the panet has existed? Without any influence from man?
