Earth’s Core Also Melts ‘Doomsday’ Glacier


Why the Thwaites Glacier, one-third the size of Turkey, was melting so quickly was not fully determined. A recent study has revealed that in addition to climate change, geothermal heat flow from under the earth’s crust also contributes to the melting of the glacier.

located in West Antarctica and “Doomsday Glacier”, so we know that the Thwaites Glacier, also known as the doomsday glacier, is melting rapidly. We know that the biggest reason for this is human-induced global warming. However, there is another reason for this extremely fast melting, and we just learned about it.

It turns out that the Thwaites Glacier is melting rapidly, not only because of climate change, but also because of the Earth’s own heat. According to a study published in the journal Nature, this geothermal warming was the answer to previous debates about why the glacier was melting so quickly.

Nothing besides human-induced global warming

Ricarda Dziadek, the geophysicist who conducted the research; The glacier, which is 1/3 the size of Turkey, coincides with a place where the earth’s crust is thinner than normal and that this causes a heat flux of 150 milliwatts per square meter to reach the glacier. expressed. This heat flow from the Earth’s core is not actually a threat to the glacier per se. However, the climate, which is warming much faster than normal for human reasons, combined with the heat waves coming from under the earth’s crust, causes the ‘Doomsday’ glacier to melt at an incredible speed and mix into the ocean.

If the Thwaites Glacier, which covers an area of ​​approximately 200,000 square meters, melts, the sea level will rise to about 200,000 square meters. 3 meters high it will be. Since this situation will not take decades, it will be too late for some regions, and countless areas will become unusable in many cities that have a coast. We hope governments realize the seriousness of the situation and important sustainable innovations such as ‘green steel’ will gradually be paved the way.
