Accelerated melting of the West Antarctic ice sheet has become an “inevitable” consequence of climate change, according to a recent study. Researchers emphasize that even if greenhouse gas emissions are controlled, the phenomenon will continue to worsen.

The western Antarctic ice sheet holds enough water to cause sea levels to rise. the average height of the sea surface, relative to a level of…) of up to 5 meters. Currently, the largest contribution to this rise comes from the ice floating in the Amundsen sea, which is melting due to of the warming of the waters of the Southern Ocean (The Southern Ocean or Antarctic Ocean or Antarctic glacial ocean is the body of water which…).
Kaitlin Naughten, a researcher at the British Antarctic Survey, says that even if global efforts succeed in limiting global warming to 1.5°C above pre-industrial levels, the melting of this ice sheet will triple by the end of the century (Un century is now a period of one hundred years. The word comes from the Latin saeculum, i, which…). According to her, “if we wanted to preserve its historic state, we should have acted several decades ago.”
Computer simulations indicate little difference in the rate of melting between four different global warming scenarios. The only scenario predicting a significant rise in global temperatures deviated from the other three, but only following 2045.
However, Naughten emphasizes that our actions to reduce greenhouse gas emissions remain crucial. “The slower the rise in sea levels (the Lente is a river in Tuscany), the easier it will be for governments and society to adapt, even if it cannot be stopped,” he says. -She.
