Please disregard the site this came from. This is not really political in any way, unless you consider a major glacier about to detach political. Just a lot of good historical past and present info about this glacier. Lots of great photos, recent research and other info.

Thwaites glacier in West Antarctica is enormous and is often referred to as the most dangerous glacier on Earth. It has also been dubbed the Doomsday glacier. The glacier holds two feet of sea level but, more importantly, it is the “backstop” for four other glaciers which holds an additional 10-13 feet of sea level rise. When Thwaites collapses it will take most of West Antarctica with it. This is not new information for those of us that follow the science.
NASA’s Jet Propulsion Laboratory made news this past January by revealing that there is a massive cavity that has been carved into the underbelly of the glacier by warm ocean water — raising alarms that the chunk of ice could collapse and disintegrate.
The cavity reportedly has an area the size of two-thirds of a Manhattan and, it as tall as a 100 story building, at 1000 feet.
The newfound hole had held fourteen billion tons of ice and, NASA observed that the horrifying melt and decay was not there just three short years ago.
It was NASA’s Icebridge program that made the discovery using ice-penetrating radar through the miles deep glacier, as well as, ”data from a constellation of Italian and German spaceborne synthetic aperture radars”.
But that was just one of the terrors that the satellites found, it confirmed fears that “Thwaites was not attached to the bedrock”.

I find this fascinating info. Spent over 4 hours gathering more info from the references/links provided in the article.
The Earth's climate and land/water mass has changed a lot over the years. This could be another major change in how the Earth is.
Just imagine Sea levels increasing rapidly 10' to 15' or more. Water rushing down the St. Lawrence into the Great Lakes. Great waves making landfall in various world locations.
Many major USA cities would be partially or entirely covered in water.
Can only imagine what will surface as this glacier melts. Millions of years of creatures, plant life and rocks, which have been buried in the glacier.
I agree that the source dramatizes many things, but check the links and references for more info.
