Silandela imisebenzi yethu yansuku zonke kulo mphakathi ngokususelwa ohlelweni oludla izinsiza zemvelo ngokuqhamuka nemingcele esingakwazi ukukala ukuguga esikukhiqizayo. Kuqhuma ukungalingani ebhalansi ngemvelo nangeplanethi, asazi nemiphumela abazoba nayo esikhathini eside, esiphakathi noma, njengoba manje sesikwazi, isikhathi esifushane.
Ukuqhuma okukhulu e-Antarctic ice sheet kune lenyuke ngamakhilomitha angama-20 ezinyangeni eziyisithupha ezidlule, engasuka endaweni engamakhilomitha-skwele angama-6.381, ngaphansi kwesifundazwe saseMadrid, ngokwesibonelo.
Izithombe ezivela eshalofini leqhwa laseLarsen C ezithwetshulwe yi- Isiphuphutheki seTerra I-NASA ikhombisa ulayini manje osungamakhilomitha ayi-128 ubude, ngokusho kombiko we-US aerospace agency. Ingxenye yeqhwa, okungelesine ngobukhulu kuleli zwekazi, ingahle iqhume.
Ososayensi basebenzela ukuqonda ushintsho olusheshayo oluzoqhamuka noqhekeko olukhulu nokuthi yini okuholele ekutheni lukhule ubude ngokushesha okukhulu. Iphrojekthi MIDAS, iqembu lase-UK elizinikezele ku ukutadisha ithala leqhwa laseLarsen C, kukhombisa ukuthi ukuguquka kwesimo sezulu kushintshe ukwakheka kweqhwa, okungaba nomthelela ekuweni ngokuphelele.
Ishalofu leqhwa laseLarsen B lawa ekuqaleni kuka-2002 futhi selinciphile eminyakeni yamuva. Ososayensi abafunda i-Antarctica banethemba lokuthi iphuka ngokuqinisekile esikhathini esingaphansi kweminyaka eyishumi.
Akukho okuningi ongakucabanga ngemiphumela yeqhwa lamanani amakhulu aqhekekayo futhi kuyisizathu salokho wazi imiphumela yokuguquka kwesimo sezulu kuwo wonke umhlaba. Ibhalansi eqinisekisa ukuthi impilo iyaqhubeka ngokuthula, kepha ngomphumela wesandla somuntu ...
