We find that that there is a linear relationship between the winter sea-ice extent in the North Atlantic and Arctic Oceans and the latitude of the southernmost permafrost limit in Eurasia. During the LGM, extensive sea-ice cover caused a zonal permafrost distribution with the southern margin extending W-E and reaching 47°N, contrasting with the present-day NW SE trending margin (66°-52°N). We infer that under global warming scenarios projected by climate models for the 21st Century the Arctic sea-ice cover decline will cause widespread instability of, mainly discontinuous, permafrost in Eurasian lowlands.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Eurasian permafrost instability constrained by reduced sea-ice cover","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Permafrost distribution; Arctic sea-ice; Permafrost instability; LGMpermafrost extent; Permafrost modelling","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2015-10-29","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000301826100002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.quascirev.2011.12.001"},"refs":null,"anarec":{"AnaID":238564,"PubliDate":2012,"Pagination":"16-23","XtraPublOfAnaID":null,"ISBN":null,"Volume":"34","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45667,"SerRR":"Quaternary Science Reviews.
