The mysterious Doomsday Glacier

There is a famous mass of ice, Thwaites Glacier, nicknamed the Doomsday Glacier, that according to Space.com "is melting in unexpected ways that could lead to its rapid collapse."

An endless mass of ice

Thwaites Glacier,  is located in Antarctica about 18 miles from Mount Murphy and is the same size as the state of Florida. This glacier, is truly gigantic.

If it melts, there will be serious consequences

Such a large glacier also entails risks, and those very risks are worrying scientists, who are finding that this glacier is melting faster than expected.

Warm water got in

Two studies conducted by researchers from the British Antarctic Survey (BAS) and published in the journal Nature suggest warm water is beginning to seep through the glacier's most vulnerable parts as a result of rising global temperatures.

It would raise the sea level by 25 inches (65cm)

The problem is that if this huge mass of ice were to melt completely, it would make clear why it is called the Doomsday Glacier: it could raise global sea levels by 25 inches or 65 centimeters.

Desolate butterfly effect

And not only that: as the studies show, a collapse of Thwaites Glacier would cause a large part of the West Antarctic Ice Sheet to melt, resulting in an absolutely catastrophic scenario.

Possible sea level rise of nearly 10 feet

Sea levels could rise by as much as ten feet (3 meters) from the "contagion effect" of the disappearance of Thwaites Glacier, which would mean the disappearance of cities, islands, countries and many coastal areas as we know them.

Farewell to farm land

The sea would not only swallow up much of the habitable land, but also inundate farm land that would be unusable due to the high concentration of salt in the water.

Potential danger

The science, as the British Antarctic Survey points out, is unequivocal. This institution has conducted not one, but two investigations, which have come to the same conclusion: Thwaites Glacier is a potential global hazard.

Ice drilling

A first group of researchers drilled through more than half a kilometer below the baseline of Doomsday Glacier, where the glacier floats on the water.

Investigating the glacier

This maneuver allowed them to check the sea temperature, salinity, melting rate and speed. Meanwhile, another team surveyed the lower part of the glacier using an underwater vehicle.

The surprising temperature of the water under the glacier

The surprise came when they discovered that the water beneath Thwaites Glacier was too warm for the area it was in, having risen by 2.5 degrees.

Ice is melting faster than expected

Among the worrying research findings is that Thwaites Glacier is melting much faster than one would expect.

Seawater temperature

Scientist Britney Schmidt, one of the authors of the paper on the glacier's dire situation said that warm water is cause the glacier to melt by 98 feet per year. “Warm water is getting into the weakest parts of the glacier and making it worse,” said Schmidt. “That is the kind of thing we should all be very concerned about.”

Salt is also a problem

Worst of all, this meltwater ends up in the base cracks of Thwaites Glacier. In other words, key areas affected not only by warmer water, but also by ocean salt accelerating ice melting.

What now?

The positive side of the research suggests that vertical melting at the base of the ice shelf is less than expected, but overall the research is disturbing and alarming.

Monitoring of crevasses

If the discovered cracks, through which the water seeps, spread to the entire glacier, the whole planet will understand why this huge chunk of ice in Antarctica is called the Doomsday Glacier.
