<prompt> Fingqa isihloko: CNN Ososayensi baye bakhulisa ukukhathazeka ngeqhwa elikhulu, elinciphayo ngokushesha e-Antarctica, bexwayisa ngokuthi linganikela kakhulu ekukhuphukeni kwamazinga olwandle. Bathi bathole izimbobo ezimbili ezingase ziholele amanzi ashisayo olwandle ezansi kweTotten Glacier enkulu futhi zilethe usongo lokuncibilika okungase kube yinhlekelele. Le nguzunga yeqhwa inkulu futhi iyancipha ngokushesha kunayo yonke e - East Antarctica. Iqukethe iqhwa elanele lokwenyusa izinga lolwandle lomhlaba wonke okungenani ngamamitha angu - 3,4, ngokusho kwabacwaningi base - University of Texas e - Austin ababephakathi kwababhali bocwaningo olusha olwanyatheliswa kuleli sonto kumagazini i - Nature Geoscience. Ososayensi babeke bathola amanzi afudumele ohlangothini olubheke olwandle lwalesi siqhingi. Kodwa kuze kube manje, babengakalitholi ubufakazi bokuthi lingasongela iqhwa elisogwini. Manje sesiyazi ukuthi kunezindlela zamanzi afudumele kakhulu eMpumalanga ye-Antarctica angena ngazo ezindaweni ezibucayi kakhulu zeTotten Glacier, kusho uJamin Greenbaum, umfundi we-Ph.D. e-University of Texas nomlobi oyinhloko walolu cwaningo. Iminyango emibili esekujuleni kolwandle eholela phansi kweqhwa inikeza incazelo yokuthi kungani i-Totten Glacier iye yancibilika ngokushesha okungaka. Ososayensi baye baxwayisa ngemiphumela yokuncibilika kweqhwa eNtshonalanga ye-Antarctica. Ngonyaka odlule i - NASA yathi ukuhlehla kwezinguzunga zeqhwa kwezinye izindawo kubonakala kungenakuthinteka. Kulinganiselwa ukuthi ukwenyuka kwamazinga olwandle okubangelwa ukuncibilika kwawo wonke amaqhwa aseTotten Glacier cishe kufana nokwehla kwawo wonke amaqhwa aseNtshonalanga ye-Antarctic. Umbiko weZizwe Ezihlangene wokushintsha kwesimo sezulu ngonyaka odlule walinganisela ukuthi izinga lolwandle lingase likhuphuke phakathi kwamamitha angu-1 kuya kwangu-3 ngo-2100. Ukwanda okunjalo kungadinga ukuba amashumi ezigidi zabantu emhlabeni wonke asuke ezindaweni ezisogwini. Kodwa lokho kubalwa akuhlanganisi ucwaningo lwakamuva lwe-Antarctica. Nakuba ukuncibilika kweTotten kungase kuthathe amakhulu amaningi eminyaka, uma ushintsho seluqalile ukuhlaziya kwethu kwembula ukuthi cishe ngeke lusashintsha, kusho uGreenbaum emazwini acashunwe yi-Australian Antarctic Division. Ukuze...  <response>: Ucwaningo olusha luveza izimbobo ezisongela iqhwa elikhulu ngamanzi afudumele. I-Totten Glacier inkulu futhi iyancipha ngokushesha kunezinye zonke eziseMpumalanga ye-Antarctica.
