The loss of a glacier the size of Florida in Antarctica could wreak havoc on the world as scientists expect it would raise global sea levels up to 10 feet. It's already melting at a fast rate — and scientists say its collapse may only rapidly increase in the coming years.
The Thwaites Glacier is the widest on Earth at about 80 miles in width. But as the planet continues to warm, its ice, like much of the sea ice around Earth's poles, is melting. The rapidly changing state of the glacier has alarmed scientists for years because of the "spine-chilling" global implications of having so much additional water added to the Earth's oceans, sparking its nickname of the "doomsday glacier."

What is there to explain? In the Alps it got hot enough to melt enough snow to explose the aircraft. Greenland on the other hand...
https://visitgreenland.com/about-greenland/greenland-climate-weather/
Greenland has an Arctic climate with average temperatures that do not exceed 10° C (50° F) in the warmest summer months. The air quality in Greenland is among the best in the world due to the country’s geographical position to the high north.
In the southern part of the country and the innermost parts of the long fjords, the temperature can, however, rise to more than 20° C (68° F) in June, July or August, and due to the fine air quality and low levels of moisture in the air, in general you are able to see very, very far.
See? No rocket science here either and a simple internet search came up with the answer in milliseconds. It simply got far warmer in the Alps than it does in Greenland. :)

One of the earliest signs that the poles were ice-free and warm 100 million years ago was the discovery at the turn of the 20th century of fossil breadfruit trees from the Cretaceous in Greenland; today such trees are at home in places like Hawaii. Since then, even more extraordinary finds have been made.
The most evocative image of a warm Arctic has emerged from the work of John Tarduno of the University of Rochester, New York. For more than a decade, Tarduno has been hunting for fossils on Axel Heiberg Island in the Canadian Arctic, just west of Greenland. The island was already well within the Arctic Circle 90 million years ago.
His team has found bones and even partial skeletons of a crocodile-like creature called a champsosaur from this period. The champsosaur was a fish-eating reptile up to 2.4 metres long that probably looked much like the gharials of India. Because these reptiles would have relied on their environment to stay warm, conditions in the far north must have been far hotter than today. “These fossils speak volumes,” says palaeoclimatologist Paul Wilson of the University of Southampton in the UK. https://1776now.org/when-crocodiles-roamed-the-arctic/#:~:text=The%20island%20was%20already%20well%20within%20the%20Arctic,probably%20looked%20much%20like%20the%20gharials%20of%20India.
Amazingly enough, it seems Earth's temperature has varied widely over the eons. Eons when no humanoids built fires or had herds of farting cows. What a puzzlement.

No idea WTF a Freedom Unit might be but I found this statement from the Smithsonian:
"But now Earth's seas are rising. Globally, sea level has risen about eight inches since the beginning of the 20th century and more than two inches in the last 20 years alone."

-
If that trend continues, it could be up another foot in 120 years?
The rate has increased from just over an inch per 20 years to 2 inches per 20 years. So if the rate continues to increase at its current pace, it will be much higher than a foot more in 120 years. If the rate holds as current, yes, 12 inches in 120 years.

Was the atmosphere breathable?
Polar ice caps also serve as reservoirs for huge amounts of the earth's water . Geologists suggest that three-quarters of the world's fresh water is frozen at the North and South Pole. Most of this freshwater ice is in the Southern Hemisphere. The Antarctic ice cap alone contains over 90% of the world's glacial ice, sometimes in huge sheets over 2.5 mi (4 km) deep and averaging 1.5 mi (2 km) deep across the continent. It has been estimated that enough water is locked up in Antarctica to raise sea levels around the globe over 200 ft (61 m), drowning most of the world's major cities, destroying much of the world's food-producing capacity, and ending civilization.
Although the polar ice caps have been in existence for millions of years, scientists disagree over exactly how long they have survived in their present form. It is generally agreed that the polar cap north of the Arctic Circle, which covers the Arctic Ocean, has undergone contraction and expansion through some 26 different glaciations in just the past few million years. Parts of the Arctic have been covered by the polar ice cap for at least the last five million years, with estimates ranging up to 15 million. The Antarctic ice cap is more controversial; although many scientists believe extensive ice has existed there for 15 million years, others suggest that volcanic activity on the western half of the continent it covers causes the ice to decay, and the current south polar ice cap is therefore no more than about three million years old.
At least five times since the formation of the earth, because of changes in global climate , the polar ice has expanded north and south toward the equator and has stayed there for at least a million years. The earliest of these known ice ages was some two billion years ago, during the Huronian Epoch of the Precambrian Era. The most recent ice age began about 1.7 million years ago in the Pleistocene Epoch . It was characterized by a number of fluctuations in North polar ice, some of which expanded over much of modern North America and Europe , covered up to half of the existing continents, and measured as much as 1.8 mi (3 km) deep in some places. These glacial expansions locked up even more water, dropping sea levels worldwide by more than 30 ft (100 m). Animal species that had adapted to cold weather , like the mammoth, thrived in the polar conditions of the Pleistocene glaciations, and their ranges stretched south into what is now the southern United States.

I did some quick research on this glacier last night. It turns out that there is no consensus that the glacier will break up, but if it does break up they think it would be over the next 200 to 1,000 years.
So if it breaks up it's not going to suddenly just break apart.
And I've seen the same article popping up. I think it's just more of the same chicken little, Doom and gloom that some organizations like to pedal.

Why are those planes that landed in WW2 in greenland deeper in the ice every time an expedition goes out there?
Glaciers grow at the top due to snow, and then compress that snow into ice due to the weight of the snow on top. So that drives the planes deeper. At the bottom or sides, ice may melt due to coming into contact with warm water (if the glacier extends to the ocean), or just be forced outward at the bottom by the enormous pressure of the ice above. So the natural progression of ice (and anything in/on it) in an active glacier is to sink as snow/ice is added above it and ice at the bottom is removed. Anything in the glacier will eventually either be dropped into the sediment at the bottom or expelled with ice it is trapped in, presuming it isn't crushed or pulverized first, though this can take some time- the oldest ice in Greenland glaciers are estimated to be over 100,000 years old.

I've read of PLANS to do so - it has never been done as a source of fresh water. It HAS been done commercially (using very small icebergs) as a source of "glacier" or "iceberg" water, however. You can buy it bottled on Amazon, for around $35/liter, or $140/gallon. It is a luxury or novelty product, not a viable supply of drinking water.

Sea ice is frozen water that forms, expands, and melts in the ocean. It is different from icebergs, glaciers, ice sheets, and ice shelves, which originate on land. For the most part, sea ice expands during winter months and melts during summer months, but in certain regions, some sea ice remains year-round. About 15 percent of the world's oceans are covered by sea ice during part of the year.
While sea ice exists primarily in the polar regions, it influences the global climate. The bright surface of sea ice reflects a lot of sunlight out into the atmosphere and, importantly, back into space. Because this solar energy "bounces back" and is not absorbed into the ocean, temperatures nearer the poles remain cool relative to the equator.
When warming temperatures gradually melt sea ice over time, fewer bright surfaces are available to reflect sunlight back into the atmosphere. More solar energy is absorbed at the surface and ocean temperatures rise. This begins a cycle of warming and melting. Warmer water temperatures delay ice growth in the fall and winter, and the ice melts faster the following spring, exposing dark ocean waters for a longer period the following summer.
Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth.
Did you know?
Sea ice also affects the movement of ocean waters. The ocean is salty and when sea ice forms, much of the salt is pushed into the ocean water below the ice, although some salt may become trapped in small pockets between ice crystals. Water below sea ice has a higher concentration of salt and is denser than the surrounding ocean water, so it sinks and moves from the surface. In this way, sea ice contributes to the circulation of the global ocean conveyor belt. Cold, dense polar water descends from the surface and circulates along the ocean bottom toward the equator, while warm water from mid-depth to the surface travels from the equator toward the poles.

So, for instance, were there any centuries where the amount of sea ice was totally static? If so, how was that verified?

Near the end of the last Ice Age 8,000 years ago, an ice dam on North America's east coast broke, releasing a torrent of fresh water seven times more voluminous than all the Great Lakes combined. It all rushed into the Atlantic Ocean over the course of only a few months.
At around the same time, ocean circulation worldwide slowed to a crawl, plunging Europe into a second ice age that lasted centuries.
Scientists have long suspected the two events were linked, and now they have the evidence from sediment core samples to prove it.
