The melting of the Antarctic ice sheet will cause sea level rises of around eight feet worldwide even if the goals of the Paris Agreement are met, research has shown. The melting is likely to occur over a long period, beyond the end of this century, but is almost certainly irreversible, due to the way the ice sheet is likely to melt, the new model reveals. Even if temperatures dropped again after rising by 2ºC (3.6F)—the temperature limit established in the Paris Agreement—the ice would not grow back to its initial state, due to self-reinforcing mechanisms that destabilize ice, according to the article published in the journal Nature . Anders , co-author of the paper from the Potsdam Institute for Climate Impact Research, said: The more we learn about Antarctica, the more dangerous the predictions become. We will get enormous sea level rise (from melting Antarctica) even if we comply with the Paris Agreement, and catastrophic amounts if we don't. Anders , co-author of the document from the Potsdam Institute for Climate Impact Research. The Antarctic ice sheet has existed in roughly its current form for about 34 million years, but its future shape will be decided in our lifetime, according to . We will be known in the future as the people who flooded New York City he told The Guardian .
The beginning of this year, temperatures of more than 20ºC were recorded for the first time in Antarctica. For his part, Jonathan Bamber, a professor Nigeria WhatsApp Number List of glaciology at the University of Bristol, who was not involved in the research, said: This study provides compelling evidence that even moderate climate warming has incredibly serious consequences for humanity, and those consequences grow exponentially as temperatures rise. Antarctica's committed sea level rise, even at 2ºC, represents an existential threat to entire nation states. We are looking to remove nations from a world map because they no longer exist. Jonathan Bamber, professor of glaciology. The consequences Earlier this week, Earth's northern ice sheet also showed the impacts of the climate crisis. Arctic sea ice has reached its annual minimum, the second lowest extent seen in four decades. On September 15, the ice was measured at 3.74m km2, marking the second time the extent has fallen below 4m km2 in the current record, according to the National Snow and Ice Data Center. from United States. Scientists said the melting ice was a clear sign of how humans were changing the planet. Twila Moon, a research scientist at the University of Colorado at Boulder, commented: It is devastating to see another Arctic summer end with so little sea ice.
There a very small area of sea ice, but it is also younger and more vulnerable overall. The Arctic is a place that has changed. All hope lies with humans to act on the climate and stop this alarming rate of ice loss. Twila Moon, research scientist at the University of Colorado at Boulder. While the Antarctic ice sheet will take centuries to melt in response to temperature increases, the new Nature paper showed how difficult it would be to reverse it. The vast Antarctic ice sheet, which covers about the same amount of land as North America and is about three miles (5 km) thick, contains more than half of the Earth's fresh water. Some of it is floating sea ice, which does not cause sea level rise in the way ice melts from land, and is subject to melting above and below due to sea warming. The researchers examined how ice on land in the region can be expected to melt, and found a strong "hysteresis" effect, which makes it more difficult for ice to reform rather than melt. When ice melts, its surface sinks lower and settles in warmer air, requiring lower temperatures for the ice to reform than to keep existing ice stable. If temperatures were to rise 4ºC above pre-industrial levels, which some predict is possible if the world fails to rapidly reduce greenhouse gas emissions, then sea level rise would occur at just 6.
