<prompt> Pfupisa nyaya yacho: CNN Masayendisiti akaratidza kunetseka pamusoro pechikomo chikuru chechando chiri kuderera nokukurumidza muAntarctica, achiyambira kuti chinogona kuita zvakawanda mukukwira kwemwero wegungwa. Vanoti vakawana makomba maviri anogona kuunza mvura inodziya yomugungwa kuzasi kweTotten Glacier huru ndokuunza tyisidziro yokunyunguduka kunoparadza. Girazi racho rakakura uye riri kudzikira nokukurumidza kupfuura mamwe ose ari muEast Antarctica. Rine chando chakakwana chokukwidza mwero wegungwa rose neinenge mamita 3,4, maererano nenyanzvi dzokuUniversity of Texas muAustin dzaiva pakati pevanyori vefundo itsva yakabudiswa vhiki ino mumagazini inonzi Nature Geoscience. Vasayendisiti vakanga vamboona mvura inodziya iri kurutivi rwomugungwa rwegungwa. Asi kusvikira zvino, vakanga vasina kuwana ufakazi hwokuti yaigona kutyisidzira mazaya echando ari pamhenderekedzo yegungwa. Iye zvino tava kuziva kuti kune nzira dzokuti mvura inodziya zvikuru yokuEast Antarctica isvike kunzvimbo dzinotambura zvikuru dzeTotten Glacier, akadaro Jamin Greenbaum, mudzidzi wepaUniversity of Texas Ph.D. uye munyori mukuru weongororo yacho. Masuo maviri ari pasi pegungwa anotungamirira pasi pegungwa rechando anotsanangura chikonzero nei Totten Glacier yave ichinyunguduka nokukurumidza kwazvo. Masayendisiti akatonyevera nezvemigumisiro yokunyunguduka kweaizi muWest Antarctica. NASA yakati gore rapera kuti kudzikira kweaizi mune dzimwe nzvimbo kunoratidzika kuva kusingamisiki. Kuwedzera kwaizoita mwero wegungwa pakunyunguduka kweaizi yose iri muTotten Glacier kunofungidzirwa kuti kunenge kwakangoenzana nokuputsika kweaizi yose yokuWest Antarctic Ice Sheet. Mushumo wenyika dzakabatana pamusoro pokushanduka kwemamiriro okunze gore rapera wakafungidzira kuti mwero wegungwa waigona kukwira pakati pe 1 tsoka ne 3 tsoka panosvika 2100. Kukwira kwakadaro kunogona kutamisa makumi emamiriyoni avanhu kubva munharaunda dzapamhenderekedzo dzegungwa kupota nyika. Asi kuverenga ikoko hakubatanidzi nzvero yazvino uno yeAntarctica. Nepo kunyunguduka kweTotten kungatora mazana amakore anoverengeka, kana kuchinja kwatanga ongororo yedu inoratidza kuti zvimwe kwaizova kusingachinjiki, Greenbaum akadaro mumashoko akanokorwa mashoko neAustralia Antarctic Division. Kuti...  <response>: Kudzidza kutsva kunoratidza kuvhurika kunotyisidzira gungwa guru rine mvura inodziya. Totten Glacier yakakura uye iri kudzikira nokukurumidza kupfuura dzimwe dzose muEast Antarctica.
