In one simulation, Arctic sea ice cover was allowed to fluctuate freely based on changing climatic conditions, while the other parallel simulation was run without year-to-year sea-ice fluctuations. <\/p>\n<p>When sea ice cover was fixed, multidecadal climate variations were reduced, both in the Arctic and North Atlantic, by 20 to 50 percent. This suggests that sea ice-air interactions play a crucial role in regulating climate variations. <\/p>\n<p>The researchers ran additional simulations using rising carbon dioxide levels by 1 percent per year to further confirm their results. They are currently examining other possible influences of Arctic sea ice, such as on El Nino-Southern Oscillation in the tropical Pacific.   <\/p>\n<p>Jiechun Deng, an atmospheric scientist at Nanjing University of Information Science and <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">Technology<\/a>, worked as a research fellow with Dai at UAlbany from 2018 to 2020. He is the lead author of the study. <\/p>\n<p>&#8220;Working with Prof. Dai at UAlbany was a truly inspiring experience,&#8221; Deng said. &#8220;Our research highlights the crucial role of sea ice-air coupling in amplifying multidecadal variability. In doing so, it contributes to the ongoing debate on the role of sea ice in the recent decadal temperature trend in both Arctic and midlatitudes.&#8221; <\/p>\n<p><b>Arctic amplification<\/b> <\/p>\n<p>This study is the latest in a <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/watch-movies-tv-seriess\/\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Watch Movies &amp; TV Series\" target=\"_blank\" rel=\"noopener\">series<\/a> of <i>Nature Communications<\/i> articles published by Dai and his team over the last several years that focus on changes in the Arctic climate. <\/p>\n<p>In 2019, Dai led a study examining the causes of Arctic Amplification (AA), the term used to describe the Arctic&#8217;s warming rates at two to three times the rest of the planet. The climate simulations used for that study showed that additional AA will not diminish until nearly all the Arctic&#8217;s sea ice has melted away in the 23rd century. <\/p>\n<p>Further, that study concluded that AA would not exist if surface fluxes were calculated with a fixed sea ice cover, again suggesting that Arctic sea ice loss has profound climatic impacts. <\/p>\n<p>&#8220;The take-home message here is that the Arctic region is very important for Earth&#8217;s climate and the rapid melting of its sea ice has and will continue to have significant climatic impacts worldwide,&#8221; Dai said.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Researchers reveal variations in Arctic amplification effect during past millennium\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Jiechun Deng et al, Sea ice\u2013air interactions amplify multidecadal variability in the North Atlantic and Arctic region, <i>Nature Communications<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41467-022-29810-7\">DOI: 10.1038\/s41467-022-29810-7<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    University at Albany<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.albany.edu\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Diminishing Arctic sea ice has lasting impacts on global climate (2022, April 28)<br \/>\n                                                 retrieved 29 April 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>\/2022-04-diminishing-arctic-sea-ice-impacts.html<\/p>\n<p>                                            This document is subject to copyright.
