Kubhalwa okungenani ubuncane bomlando weqhwa olwandle lwase-Antarctic

I-Iceberg e-Antarctica

Kubangelwa yini? Ngokuya kocwaningo olwenziwe ososayensi beBritish Antarctic Survey (BAS), olushicilelwe kulo magazini Izincwadi Zokucwaninga Zezepolitiki, kube yi uchungechunge lwesiphepho oluphawulekayo kwenzeke phakathi kwezinyanga zikaSepthemba kuya kuNovemba 2016.

Lezi zimo zilethe umoya oshisayo nemimoya enamandla, ehlanganisiwe, ayincibiliki kakhulu noma ngaphansi Amakhilomitha-skwele angama-75.000 eqhwa lolwandle ngosuku, okungalingana nokulahlekelwa ucezu lweqhwa elilingana nePanama njalo emahoreni angama-24.

Ukwehla okuphawuleka kakhulu okuye kwabonwa selokhu amarekhodi aqala ngo-1978. Kumele kuqashelwe ukuthi iqhwa lolwandleNjengoba kuchazwe nguJohn Turner, usosayensi wesimo sezulu e-BAS futhi ongumlobi oholayo wocwaningo, uzacile kakhulu, ukujiya kwemitha ngokwesilinganiso. Lokhu kwenza kube njalo sengozini kakhulu emimoyeni enamandla.

Ingabe lesi simo singabangelwa ukushintsha kwesimo sezulu? Iqiniso liwukuthi, cha. Kuyiqiniso ukuthi ososayensi basebenzisa iqhwa lolwandle njengenkomba yezinguquko esimweni sezulu, futhi empeleni, ngokusho kukaTurner, amarekhodi e-whaling anikeza ososayensi imikhondo kuze kube sezingeni leqhwa lasolwandle. edlule i-Antarctica, kodwa kunzima ukuqhathanisa leyo datha namarekhodi wesathelayithi. Ngaphezu kwalokho, kugcizelela ukuthi isimo sezulu sase-Antarctic siyahlukahluka ngokumangalisayo.

Abanesiqiniseko sako ukuthi uma ukukhishwa kwegesi ebamba ukushisa kuqhubeka nokukhuphuka izivunguvungu eziningi futhi ezinamandla cishe ezingeni eliphakathi nendawo. Kodwa-ke, okwamanje akukwazi ukuqinisekiswa ukuthi izivunguvungu zangasekupheleni kuka-2016 zibangelwa imisebenzi yabantu.

Kuze kube yileso sikhathi, indawo yeqhwa lasolwandle i-Antarctic yanda kakhulu, okuyinto ethakazelisa kakhulu kososayensi, abafuna ukuthola ukuthi kungani iqhwa lakhula uma izinga lokushisa lomhlaba wonke liyanda. Mhlawumbe lokhu kukhula kungesinye isici sokushintsha kwesimo sezulu.


Okuqukethwe yi-athikili kunamathela ezimisweni zethu ze izimiso zokuhlelela. Ukubika iphutha chofoza lapha.
