For decades, satellite observations have shown that the glaciers of the Amundsen Sea in West Antarctica are losing mass at an accelerated rate and the melting of the ice sheet in that region may have already reached a point of no return. Previous studies had demonstrated the instability of this sea, west of Antarctica, by examining its short-term evolution with numerical models. A new study, led by scientists at the Potsdam Institute for Climate Impact Research (Germany), goes a step further and offers a long-term simulation of the evolution of the entire West Antarctic ice sheet. The results, published in PNAS, confirm that the Amundsen region is unstable. “Our computer models reveal that with the instability of the relatively small Amundsen region, the entire area of the West Antarctic ice sheet will collapse and contribute to a global sea level rise of three meters,” he tells .
According to scientists, we may be seeing the beginning of a period of prolonged disintegration of sea ice into the ocean. The local retreat America Mobile Number List of the ice sheet and its thinning “is very likely to continue in the future,” says , who adds that observations over the next few decades will confirm that we are facing a large-scale retreat from this area of Antarctica. A thaw 'out of control' Simulations indicate that the region will become destabilized after 60 years of current melt levels. But for the authors, this area is already unstable so this threshold can be quickly surpassed. And if this happens, in the coming centuries a three-meter rise in sea level may be inevitable. “If the results are taken into account on a millennium scale, sea level will rise by one meter during the first years. We will reach the eventual three meters in about years,” says the German scientist. But “it can be faster,” warns the expert.
Commitments, then it must pay the remaining 130 million. For several months, defective airbags, which can explode even in cases of minor crashes, have been the cause of scandal around the world and especially in the United States. According to the NHTSA, the defect affects some 23 million airbags in the United States that will have to be recalled, although the process risks taking a long time. Honda, first customer, has also been weakened by this scandal, which forced it to review 24.5 million vehicles. After reviewing "millions of pages of internal documents provided by " in recent months, the third Japanese manufacturer points out that this supplier "had fabricated and manipulated data. We expect our suppliers to act with integrity in all circumstances and we are deeply concerned by this behavior," stressed Honda, which announced the replacement in the "near future" of the affected airbags with parts from "other suppliers." During a press conference, a leader, Hiroshi Shimizu, refused to detail the consequences of Honda's decision, which represents more than 10% of its sales, although he assured that this matter will have "an impact on the management" of the group.
