Njengoko besiphawula kutshanje kwifayile ye- blog, unyibiliko lushiya ilizwekazi iAntarctic lingena mkhenkce. Kwiintsuku ezimbini ezidlulileyo, into esele ibizwa ngokuba yi ngumkhenkce omkhulu emhlabeni: Umfundi weLarsen C.
Ukulinganisa i-trillion yeetoni, onke amehlo ayekade ejonge kuye ixesha elide. Kwaye, kuya kwenzeka ntoni ngoku? Okwangoku, iAntarctica ayisayi kujonga ngokufanayo; hayi ilize, ilahlekile ngaphezulu kwe-12% yendawo yayo yomkhenkce.
Umkhenkce omkhulu, nangona wawusele unokudada kangangexesha elithile, awuzukuchaphazela ngokuthe ngqo kumphakamo wolwandle; Ngoku oososayensi banenkxalabo njengoko befumanise ukuba i-Antarctic ice cover ayizinzanga kangako kunaphambi kokuqhekeka, oko kuthetha ukuba ii-icebergs ezintsha zinokubakho kwixesha elifutshane okanye eliphakathi.
Ukophula umthetho kukaLarsen C bekufundwe ixesha elide, ukusukela oko iqonga likaLarsen A lawa ngo-1995, nango-2002 uLarsen B. Ngalo nyaka, 2017, ukusuka kuJanuwari ukuya kuJuni ubude besiqhekeza seLarsen C bonyuke ngaphezulu kwe-200km. Yadityaniswa kwilizwekazi ngumgama womkhenkce osisi-4,5 km, de ekugqibeleni, phakathi kwe-10 ne-12 kaJulayi, yaqhekeka ngokupheleleyo.

Akukaziwa ukuba kuzakwenzeka ntoni na ukususela ngoku. Inokwenzeka ukuba, i-iceberg iya kuqhekeka ibe ngamaqhekeza amaninzi anokuthi ekugqibeleni abe nefuthe kumgangatho wolwandle. Okwangoku, eyona nto ixhalabisayo kukuba ukuba iqondo lobushushu lehlabathi liqhubeka nokunyuka, I-Antarctica inokuphelelwa ngumkhenkce.
Sikutyala oku kubi kwi-Sentinel-1 satellite ye-European Space Agency, neyayisetyenziselwa ukubeka esweni ukuphuhliswa kwe-Larsen C kunyaka ophelileyo, nakwi-Aqua MODIS satellite kunye nesixhobo seSuomi VIRS, zombini ukusuka kwi-NASA.
