\nFolosind imagini de \u00eenalt\u0103 rezolu\u0163ie capturate de sateli\u0163ii NASA \u00eentre 2000 \u015fi 2019, un grup de oameni de \u015ftiin\u0163\u0103 a descoperit c\u0103 ghe\u0163arii, f\u0103r\u0103 cei din Groenlanda \u015fi Antarctica, care au fost excluse din studiu, au pierdut \u00een medie 267 gigatone de ghea\u0163\u0103 pe an, relateaz\u0103 The Guardian.<\/p>\n
\nCercet\u0103torii au descoperit, de asemenea, c\u0103 topirea masei ghe\u0163arilor s-a accelerat. Ghe\u0163arii au pierdut anual 227 de gigatone de ghea\u0163\u0103 \u00een perioada 2000-2004, dar aceasta a crescut p\u00e2n\u0103 la o medie de 298 de gigatone dup\u0103 2015.<\/p>\n
\nTopirea a avut un impact semnificativ asupra nivelului m\u0103rii care a crescut cu aproximativ 0,74 milimetri pe an, adic\u0103 21% din cre\u015fterea global\u0103 a nivelului m\u0103rii observat\u0103 \u00een aceast\u0103 perioad\u0103.<\/p>\n
\nGhe\u0163arii tind s\u0103 aib\u0103 un r\u0103spuns mai rapid la schimb\u0103rile climatice \u00een compara\u0163ie cu straturile de ghea\u0163\u0103 din Groenlanda \u015fi Antarctica.<\/p>\n
\nStudiul ar putea umple lacune importante \u00een ceea ce prive\u015fte \u00een\u0163elegerea topirii ghea\u0163ii, duc\u00e2nd la predic\u0163ii mai exacte, a spus co-autorul studiului Robert McNabb, un om de \u015ftiin\u0163\u0103 de la Universitatea Ulster din Marea Britanie.<\/p>\n
\nGhe\u0163ari din Alaska, Islanda, Alpi, mun\u0163ii Pamir \u015fi Himalaya au fost printre cei mai afecta\u0163i de topire, au descoperit cercet\u0103torii. Ghe\u0163arii cu comunit\u0103\u0163ile \u00een apropriere ofer\u0103 o surs\u0103 important\u0103 de ap\u0103, iar declinul acestora ar putea duce la deficien\u0163e grave de ap\u0103 \u00een zona importante din lume.<\/p>\n
\nUltimele studii privind schimb\u0103rile climatice arat\u0103 c\u0103 nivelul m\u0103rii va cre\u015fte cu mai mult de un metru p\u00e2n\u0103 \u00een 2100.<\/p>\n","protected":false},"excerpt":{"rendered":"
