Enye yezindawo ezonakaliswe kakhulu nezithintekile emhlabeni yi-Antarctica. Ukuguquka kwesimo sezulu nokufudumala kwembulunga yonke yizona zizathu ezimbili eziyinhloko zokuthi kungani iqhwa e-Antarctica lincibilika ngokuxhuma nemingcele.
Udaba luba nzima kakhulu ngemuva kokuthi iqembu labacwaningi selibonile ukwakheka kwamachibi acishe abe yi-8.000 ngenxa yokuncibilika kweqhwa ebilokhu yenzeka kusukela ngo-2000.
Lawa ngamachibi amahle aluhlaza okwesibhakabhaka abangela ukuncibilika kweqhwa kuyo yonke i-Antarctica ukusheshisa ngendlela ekhathaza ngempela. Kungokokuqala ukuthi lesi senzakalo sibonwe empumalanga ye-Antarctica lapho kutholakala khona iqhwa elikhulu kunawo wonke eMhlabeni. Kuze kube manje, bezingakatholakali izinkinga zokuncibilika kule ndawo, kepha imiphumela yokuguquka kwesimo sezulu isiqala ukuzwakala kuleyo ngxenye ye-Antarctica.
Ngokusho kochwepheshe ngale ndaba, lawa machibi aluhlaza okwesibhakabhaka akhiwa ngesikhathi sasehlobo ngenxa yamazinga okushisa aphezulu futhi imvamisa akha imifula ngaphansi kweqhwa, elenza ukuba lincibilike kakhulu. Yize usayizi wamachibi la usengakabi mkhulu, en umcimbi wokuthi ukufudumala kwembulunga yonke kuyaqhubeka nokuba kubi, kungadala ukuthi inani lamachibi ase-Antarctica lenyuke ngendlela ekhathaza kakhulu eminyakeni ezayo.
Le ndaba ibucayi kakhulu kunokubukeka kwayo ekuqaleni kungaba nokukhuphuka kwesikhathi eside kolwandle olungafika kumamitha ayisithupha, okungadala ukunyamalala kwenani elikhulu lamadolobha asogwini emhlabeni wonke. Ekugcineni, kufanele kukhunjulwe ukuthi i-East Antarctica iyisisindo esikhulu seqhwa emhlabeni, ngakho-ke inkinga ingaba yimbi nakakhulu.
