Is this not an example of calving, meaning the glacier is getting bigger?
Most Glaciers calve as the result of them flowing to the sea. The ice becomes unstable and weakened from warmer summer temperatures. Steep terrain also weakens the ice and gravity does the rest. The volume of ice behind the glaciers has a minimal effect until it rises above the continental terrain and is able to begin moving.
There is also the effects of friction from all that mass and weight. That alone will melt the bottom ice formations and lubricate the mass to aid movement. Add to that the higher subterranean temperatures and geothermal effects from the Earth’s crust, and the ice will melt from below and move where ever it can.
Global Warming being the cause of this much Continental ice mass to move or break up on this level is complete ignorance. This is not ice that is melting from the outside in, it is melting from the bottom up. It is impossible for Global Warming to be the cause. It’s simply a fantastic lie.
Shhh....there will be no rational thought allowed, amidst the hysteria!
