Anadolu<\/a>, Mahmut Oguz Selbesoglu, directorul Centrului de Cercetare Polar\u0103 al Universit\u0103\u021bii Tehnice din Istanbul, a subliniat importan\u021ba ghe\u021barilor \u0219i a ghe\u021bii marine \u00een men\u021binerea acestui echilibru radiativ. El a explicat c\u0103, pe m\u0103sur\u0103 ce ghea\u021ba se tope\u0219te, acest echilibru este perturbat: evaporarea cre\u0219te, efectul de ser\u0103 se intensific\u0103, iar procesul de \u00eenc\u0103lzire global\u0103 se accelereaz\u0103, gener\u00e2nd un ciclu vicios de pierdere a ghe\u021bii.<\/p>\nSelbesoglu a eviden\u021biat faptul c\u0103 Arctica se \u00eenc\u0103lze\u0219te de patru ori mai repede dec\u00e2t rata medie global\u0103. El a men\u021bionat c\u0103 topirea ghe\u021bii se concentreaz\u0103 \u00een regiunile marginale de ghea\u021b\u0103 din Marea Barents, Marea Bering \u0219i zonele de coast\u0103 ale Atlanticului de Nord.<\/p>\n
\u00cen plus, el a subliniat c\u0103, de\u0219i stratul de ghea\u021b\u0103 poate s\u0103 se extind\u0103 temporar, acesta devine mai sub\u021bire \u0219i, prin urmare, mai vulnerabil la topire. \u201eMaximul de ghea\u021b\u0103 marin\u0103 din anul precedent a fost, \u00een acela\u0219i timp, minimul anual \u0219i minimul istoric\u201d, a explicat el. \u201eAproape toate valorile record \u00eenregistrate au avut loc \u00een ultimele decenii, ceea ce sugereaz\u0103 o tendin\u021b\u0103 sistematic\u0103 \u0219i accelerat\u0103 de pierdere a ghe\u021bii. Aceasta nu se refer\u0103 doar la topirea verii, ci \u0219i la o reducere a cantit\u0103\u021bii de ghea\u021b\u0103 care ar trebui s\u0103 se formeze \u00een timpul iernii. Aceasta este o dovad\u0103 a sl\u0103birii sistematice \u0219i structurale a sistemului\u201d, a ad\u0103ugat Selbesoglu.<\/p>\n
El a descris acest proces ca fiind un lan\u021b de evenimente interconectate. Pe m\u0103sur\u0103 ce suprafa\u021ba alb\u0103 se mic\u0219oreaz\u0103, mai mult\u0103 radia\u021bie solar\u0103 este absorbit\u0103, gener\u00e2nd o cre\u0219tere a temperaturii, ceea ce duce la o pierdere \u0219i mai mare de ghea\u021b\u0103. Acest fenomen contribuie la o evaporare sporit\u0103 \u0219i la un efect de ser\u0103 mai intens, ceea ce cauzeaz\u0103 schimb\u0103ri climatice \u0219i fenomene meteorologice extreme.<\/p>\n
Selbesoglu a subliniat c\u0103 pentru a opri pierderea ghe\u021bii, este esen\u021bial s\u0103 reducem emisiile de gaze cu efect de ser\u0103, s\u0103 elimin\u0103m treptat combustibilii fosili \u0219i s\u0103 acceler\u0103m tranzi\u021bia c\u0103tre surse de energie regenerabil\u0103. De asemenea, este necesar\u0103 reducerea emisiilor de carbon negru \u0219i implementarea unor m\u0103suri specifice pentru regiunea arctic\u0103.<\/p>\n
\u00cen concluzie, schimb\u0103rile care au loc \u00een Arctica nu au doar implica\u021bii locale, ci \u0219i globale, servind drept un semnal de avertizare timpurie pentru viitorul \u00eentregului sistem climatic.<\/p>\n","protected":false},"excerpt":{"rendered":"
