Their analysis was published in the scientific journal <i>Nature<\/i>.<\/p>\n<p>If emissions remain high beyond that, the EAIS could contribute around one to three meters to global sea levels by 2300, and two to five meters by 2500, they said.<\/p>\n<p>However, if emissions were dramatically reduced, EAIS could contribute around two centimeters of sea level rise by 2100, according to the assessment. <\/p>\n<p>This would represent far less than the ice loss expected from Greenland and West Antarctica. <\/p>\n<p>&#8220;A key conclusion from our analysis is that the fate of the East Antarctic Ice Sheet remains very much in our hands,&#8221; said lead author Chris Stokes, from Durham University&#8217;s Department of Geography.<\/p>\n<p>&#8220;This ice sheet is by far the largest on the planet, containing the equivalent of 52 meters of sea level and it&#8217;s really important that we do not awaken this sleeping giant.<\/p>\n<p>&#8220;Restricting global temperature increases to below the 2\u00b0C limit set by the Paris Climate Agreement should mean that we avoid the worst-case scenarios, or perhaps even halt the melting of the East Antarctic Ice Sheet, and therefore limit its impact on global sea level rise,&#8221; he added.<\/p>\n<p><b>Computer simulations<\/b><\/p>\n<p>The study did note that the worst scenarios projected were &#8220;very unlikely&#8221;.<\/p>\n<p>World leaders agreed at the 2015 UN Climate Change Conference in Paris to limit global warming to well below 2\u00b0C and pursue efforts to limit the rise to 1.5\u00b0C.<\/p>\n<p>The research team, which included scientists from the UK, Australia, France and the US, analyzed how the ice sheet responded to past warm periods when making their predictions.<\/p>\n<p>They ran computer simulations to model the effects of different greenhouse gas emission levels and temperatures on the ice sheet by the years 2100, 2300 and 2500.<\/p>\n<p>They found evidence to suggest that three million years ago, when temperatures were around 2-4\u00b0C higher than present, part of the EAIS &#8220;collapsed and contributed several meters to sea-level rise&#8221;.<\/p>\n<p>&#8220;Even as recently as 400,000 years ago\u2014not that long ago on geological timescales\u2014there is evidence that a part of the EAIS retreated 700 km inland in response to only 1-2\u00b0C of global warming,&#8221; they added.<\/p>\n<p>Nerilie Abram, a co-author of the study from the Australian National University in Canberra, warned the sheet &#8220;isn&#8217;t as stable and protected as we once thought.&#8221;<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Fate of the world&#8217;s biggest ice sheet is in our hands, scientists say\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Chris Stokes, Response of the East Antarctic Ice Sheet to past and future climate change, <i>Nature<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41586-022-04946-0\">DOI: 10.1038\/s41586-022-04946-0<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41586-022-04946-0\">www.nature.com\/articles\/s41586-022-04946-0<\/a><\/p><\/div>\n<p class=\"article-main__note mt-4\">\n                                                \u00a9 2022 AFP<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 World&#8217;s biggest ice sheet could cause massive sea rise without action: study (2022, August 13)<br \/>\n                                                 retrieved 13 August 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-08-world-biggest-ice-sheet-massive.html<\/p>\n<p>                                            This document is subject to copyright.
