Geothermal heat flow is making matters worse. To Make Matters WorseThe Thwaites Glacier (aka the Doomsday Glacier) is melting fast. Thats no surprise. Its also melting particularly fast, in part, because of manmade climate change. Thats also no surprise. What is surprising is a new study published in Naturethat revealed the Earths natural heat is also speeding up the glacial melt. In fact, researchers say the relatively thin crust beneath West Antarctica (where the Doomsday Glaciers located) to exposing the glacier to higher geothermal temperatures.Our measurements show that where the Earths crust is only 17 to 25 kilometers thick, geothermal heat flow of up to 150 milliwatts per square meter can occur beneath Thwaites Glacier, Ricarda Dziadek, lead author of the study and geophysicist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research in Germany, said in a statement attained by LiveScience.Add It to the PileOf course, warmer temperatures originating for the Earths inner mantle arent the only hurdles the Doomsday Glacier faces. On top of that, theres the issue of manmade climate change thats progressively warming the waters. Researchers at the University of Gothenburg discovered that waters underneath the glacier are so warm that its wearing the ice away faster than anyone anticipated due to the global rise in temperatures. True to its name, if the Doomsday Glacier melts, itll result in a catastrophic rise in water levels all over the world. After all, the Thwaites Glacier spans roughly 119,300 square miles. Lets hope something like the recent green steel development kicks us into gear to do more about it.READ MORE: Antarcticas Doomsday Glacier is fighting an invisible battle against the inner Earth, new study finds [LiveScience]More on the Doomsday Glacier: Scientists Discover Doomsday Glacier More Unstable Than Ever
