\u00cen primele zile ale lunii februarie, Marea Baltic\u0103 a pierdut aproximativ 275 de miliarde de tone de ap\u0103. Aceast\u0103 pierdere masiv\u0103 a condus la atingerea unui nivel cu 67 cm mai mic dec\u00e2t orice valoare \u00eenregistrat\u0103 din anul 1886. Este un contrast mare fa\u021b\u0103 de tendin\u021ba global\u0103 de cre\u0219tere a nivelului oceanelor, acest bazin semi\u00eenchis manifest\u00e2nd un fenomen invers, mai arat\u0103 Euronews<\/a>.<\/p>\n

Institutul de Oceanologie al Academiei Poloneze de \u0218tiin\u021be a identificat cauza imediat\u0103 a acestui fenomen: o combina\u021bie de v\u00e2nturi puternice din est \u0219i un sistem atmosferic de \u00eenalt\u0103 presiune. Acestea au ac\u021bionat \u00eempreun\u0103 pentru a \u00eempinge masa de ap\u0103 prin str\u00e2mtorile daneze c\u0103tre Marea Nordului.<\/p>\n

Cu toate acestea, exper\u021bii subliniaz\u0103 c\u0103 astfel de episoade extreme sunt str\u00e2ns legate de schimb\u0103rile climatice \u0219i de destabilizarea vortexului polar. Aceast\u0103 destabilizare altereaz\u0103 curen\u021bii atmosferici, duc\u00e2nd la apari\u021bia unor blocaje meteorologice atipice \u0219i de lung\u0103 durat\u0103.<\/p>\n

\u201eEfectul de frigider deschis\u201d \u0219i accelerarea \u00eenc\u0103lzirii \u00een Arctica<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 explic\u0103 acest fenomen prin a\u0219a-numitul \u201eefect de frigider deschis\u201d. Practic aerul rece din zona arctic\u0103 se deplaseaz\u0103 spre sud, ca urmare a \u00eenc\u0103lzirii accelerate a regiunii Arctice, o zon\u0103 care se \u00eenc\u0103lze\u0219te de patru ori mai rapid dec\u00e2t media global\u0103.<\/p>\n

Topirea ghe\u021barilor, desalinizarea apelor \u0219i cre\u0219terea temperaturilor perturb\u0103 echilibrul delicat al ecosistemelor marine. Apele mai calde \u0219i cu un con\u021binut redus de sare stimuleaz\u0103 \u00eenflorirea algelor, un proces care reduce semnificativ nivelul de oxigen. De asemenea, afecteaz\u0103 grav biodiversitatea acvatic\u0103.<\/p>\n

Biologii marini atrag aten\u021bia c\u0103 modific\u0103rile climatice accelereaz\u0103 o reorganizare a speciilor \u00een regiunile nordice. Speciile provenite din habitate mai sudice \u00ee\u0219i extind aria de r\u0103sp\u00e2ndire c\u0103tre nord, intr\u00e2nd \u00een competi\u021bie cu fauna arctic\u0103 autohton\u0103.<\/p>\n

\u00cen paralel, cre\u0219terea temperaturii oceanelor genereaz\u0103 fenomenul de albire a coralilor. Este un proces devastator \u00een care recifele \u00ee\u0219i pierd algele simbiotice esen\u021biale \u0219i se degradeaz\u0103 rapid.<\/p>\n

Exper\u021bii avertizeaz\u0103 c\u0103, \u00een urma unui val de c\u0103ldur\u0103 marin\u0103, un recif plin de via\u021b\u0103<\/a> se poate transforma \u00eentr-un de\u0219ert subacvatic \u00een decurs de doar c\u00e2teva s\u0103pt\u0103m\u00e2ni.<\/p>\n

Marea Baltic\u0103: mai pu\u021bin poluat\u0103, dar tot mai expus\u0103 riscurilor<\/h2>\n

De\u0219i, \u00een deceniile recente, organiza\u021bia HELCOM \u0219i eforturile comune ale statelor riverane au contribuit la o reducere a polu\u0103rii, Marea Baltic\u0103 continu\u0103 s\u0103 fie un ecosistem fragil. Salinitatea sa redus\u0103 limiteaz\u0103 varietatea speciilor marine, iar starea popula\u021biei de cod este deosebit de precar\u0103.<\/p>\n

Speciali\u0219tii avertizeaz\u0103 c\u0103 procesul natural de auto-purificare al acestei m\u0103ri este lent \u0219i ar putea necesita decenii pentru a-\u0219i face sim\u021bite efectele.<\/p>\n","protected":false},"excerpt":{"rendered":"
