Antarctica, “a lot of heat under the ice.” The ocean could rise by half a meter by the end of the century – Libero Quotidiano

under iceAntarctica the giant Thwaites, 120,000 square kilometers of white expanse, risks melting faster between global warming and the geothermal source running beneath it, with a devastating effect on our climate. Mr Faust Viraccioli, Director of the National Institute of Geophysics in Trieste explains that what could happen. “The behavior of the two It can affect the entire casing. And on the ocean where the ice will pour. Our studies examined the sources of magnetic deflections by indirect geophysical methods, in our case aeromagnetic. This is because in Antarctica only 1% of the rocks have surfaced and reach the rest when the ice layer is high Even two or three kilometers is very complicated.”

What could happen: “It affects the amount of water under the cap, which acts as a lubricant allowing the ice to flow more easily over the bedrock and also deforms differently. The higher the heat flow, the lower the viscosity of the mantle. When the cap melts, the rock rises. If the viscosity is lower, this bounce is faster. This phenomenon is very interesting for the ortologists of the continent, of course, the faster it flows, the more sensitive climate change can be. By the end of the century, the sea could rise by half a meter‘, reveals in an interview with day.

What is Antarctica? “A land of peace, where geopolitical clashes do not come. It is clear that among Chinese or American scientists there can be a challenge to those who make new discoveries, but in general we work side by side and no matter which country claims the territory, Australia, Chile, Norway or United Kingdom, Argentina, France or New Zealand: We only have one master: the flag‘ concluded Ferraccioli.
