Ukwanda kwamafu e-Arctic kwenza isimo sokushisa sibe sibi kakhulu

ukuncibilika kwe-arctic

Umphumela wokushisa nokushisa kwesimo sezulu unemiphumela nezimbangela ezingaziwa emphakathini wesayensi. Asazi kahle ukuthi kungazithinta kanjani izenzo ezithile zomuntu kanye nemithelela yokudla, njll. Kulokhu sibona ukuthi ukuncibilika okwenzekayo ngenxa yokushisa komhlaba kubanga kanjani ukwanda kwesibhakabhaka se-Arctic futhi lokhu kukhulisa umthelela womphumela wokushisa okushisayo.

Yini le nto ngenxa?

Ukuncibilika e-arctic

Izinga leqhwa e-Arctic yilona eliphansi kakhulu elirekhodiwe kusukela ngo-1978 nokuziphatha kwesimo sezulu ezingxenyeni ezahlukahlukene zalo kuya ngokuya kungalindeleka ngenxa yokungcola. Abaphenyi nososayensi bazama ukuqonda ukuthi ukuncibilika nokwenyuka kwesembozo sefu kuyikhulise kanjani imiphumela yomthelela wokubamba ukushisa esigxotsheni.

Umbono wososayensi usekelwe ekungcolisweni njengembangela enkulu yalezi zinguquko. Okokuqala, ukufudumala kwembulunga yonke nokwanda kwamazinga okushisa emhlabeni kwenza iqhwa lase-Arctic licibilike, ngakho-ke ukukhanya kwelanga akusabonakaliseki kubuyele esikhaleni ezindaweni lapho kungekho khona iqhwa. Ngemuva kokuthi ukuncibilika kungakhombisi nje kuphela, kepha futhi kumunca ukukhanya, okudala ukuthi umswakama okhishiwe ukhuphuke wakhe amafu. Inkinga ivela lapho la mafu esebenza njengengubo, ekugcina ufudumele.

Ukuphenya ngomphumela walesi simo esimweni sezulu, kwenziwa umsebenzi womoya lapho indiza yenza khona izindiza ezithatha imininingwane eqhathaniswa nezinye izilinganiso ezivela kumasathelayithi. Ososayensi banesizathu sokucabanga ukuthi ukuncibilika nokulahleka kweqhwa kubangele ukwanda kokwakhiwa kwamafu. Futhi yingakho badinga ukunquma imithelela abangayidedela.
