Ndi anthu ochepa, munthu angaganize kuti Arctic akanakhala malo opanda pulasitiki, koma kafukufuku watsopano akuwonetsa kuti sichowonadi. Ofufuzawo akuphunzira ku Arctic Ocean akupeza zinyalala pulasitiki kulikonse. Malinga ndi Tatiana Schlossberg wa The New York Times, madzi a Arctic amawoneka ngati malo otaya pulasitiki ndi mafunde a nyanja.
Pulasitiki idapezeka mu 2013 ndi gulu la anthu ofufuza paulendo wa miyezi isanu padziko lonse lapansi lonse lonselo lomwe lidakwera. Ali m'njira, adatenga zitsanzo za madzi am'nyanja kuwunikira kuwonongeka kwa pulasitiki. Ngakhale atakhala ndi pulasitiki nthawi zambiri amakhala wotsika kwambiri, anali m'dera lina ku Greenland komanso kumpoto kwa nyanja yazovala kumene, anali okwera kwambiri. Adasindikiza zomwe adapeza munkhaniyi sayansi yapitayo.
Pulogalamuyi imawoneka kuti ikuyenda mtunda wa thermohaline syrre, lamba wonyamula "lamba wonyamula" zomwe zimanyamula madzi kuchokera kunyanja ya Atlantic kupita ku Nyanja. "Greenland ndi Nyanja ya Barland idatha pa polari pa polar andrés Cozar Cazar Cabañas, wofufuza ku University of Cadiz ku Spain, adamasulidwa.
Ofufuzawo akuyerekeza kuti kuchuluka kwathunthu kwa pulasitiki m'derali kuli matani mamiliyoni, okhala ndi zikwizikwi za mazira ang'onoang'ono. Kuchulukana kungakhale kokulirapo, ofufuzawo adati, pamene pulasitiki akhoza kukhala kuti wadzipeza pa nyanjayo m'derali.
Eric Van Sebille, Co-Wofeser Phunziroli, adauza Rakele Debille pamlandu kuti: "Pomwe ambiri a Arctic ali bwino, pali magwero a Blusaye, ndiye kuti pali madzi oyipitsidwa kwambiri."
Ngakhale ndizokayikitsa kuti pulasitikiyo idzachotsedwa mwachindunji munyanja ya ayeziyo (madzi ozizira a madzi pakati pa Scandinavia ndi Russia), zomwe zapezeka zapulasitiki zikusonyeza kuti zakhala munyanja kwakanthawi.
"Zidutswa za pulasitiki zomwe poyamba zingakhale mainchesi kapena mapazi kukula kukhala owala, kenako ndikuphwanya chidutswa chaching'ono komanso cha pulasitiki, chomwe timachitcha maikolopi." - Carlos Duarte, adati kuphunzira Ch-wolemba Chris Moonere of Washington Post. "Izi zimatenga kuchokera zaka zingapo mpaka zaka zambiri. Chifukwa chake mtundu wa zinthu zomwe tikuwona zidalowa m'madzi zaka makumi angapo zapitazo. "
Malinga ndi Schlossberg, matani 8 miliyoni apulasitiki apulasitiki amalowa m'nyanja chaka chilichonse, ndipo masiku ano pafupifupi matani 110 miliyoni a kudziunjikira pulasitiki padziko lapansi. Pamene zinyalala pulasitiki ku Arctic madzi ndi ochepera peresenti yonse, duarte adauza Muni kuti kuchuluka kwa zinyalala za pulasitiki ku Arctic kumangoyambira. Zaka makumi atatu za pulasitiki kuchokera kum'mawa kwa US ndi Europe zikadali panjira ndipo pamapeto pake zidzathera ku Arctic.
Ofufuzawo azindikira zovuta zingapo zomwe zili m'nyanja zam'madzi padziko lapansi komwe maikolofoni amayamba kudziunjikira. Zomwe zikudandaula tsopano ndikuti Arctic idzagwirizana ndi mndandandawu. "Dera ili ndi mathero akufa, mafunde a nyanja amasiyira zinyalala pamtunda," wowerenga Co-wolemba Maria-wolemba Pedrotti adati mu makina osindikizidwa. "Titha kukhala a Mboni za malo ena padziko lapansi popanda kumvetsetsa bwino zoopsa za maluwa ndi fauna."
Ngakhale malingaliro ena-in-in-in-thambo kuti muyeretse zinyalala zam'madzi kuchokera ku pulasitiki pano zikufufuzidwa pano, makamaka osindikizidwa kwambiri panyanja, ofufuzawo adatha chifukwa cholongosola bwino kuti aletse mawonekedwe a pulasitiki. Munyanja.
Jason Daley ndi madison, wolemba wa Wisconsin-wochokera ku mbiri yachilengedwe, sayansi, amayenda, ndi chilengedwe. Ntchito yake yasindikizidwa mu Disciver, sayansi yodziwika bwino, kunja, magazini ya abambo ndi magazini ena.
