Ukunyibilika koMlambo woVuko kubonisa intlekele... unamathela ezinziphoni zawo.

Kwisilumkiso esothusayo, uninzi lwezazinzulu zalumkisa ukuba i-"Thwaites Iceberg" enkulu kwintshona ye-Antarctica, ijongene nokurhoxa ngendlela engazange ibonwe ngaphambili, enokuba yingozi kwiplanethi.

Baye bafumanisa ukuba i-Thwaites glacier, ebizwa ngokuba yi-Resurrection Glacier, inokuhla ngokukhawuleza kwiminyaka ezayo, iphakamisa inkxalabo malunga nokunyuka okugqithiseleyo kwinqanaba lolwandle eliya kuhamba kunye nokutshatyalaliswa kwayo.

Kuphononongo olupapashwe ngoMvulo kwijenali yeNdalo yeGeoscience, izazinzulu zenze imephu yokubuyela kwembali yomkhenkce, ngethemba lokufunda kwixa elidlulileyo kwaye baqikelele ukuba yintoni enokwenziwa ngumkhenkce kwixesha elizayo, ingxelo ye-CNN.

Baye bafumanisa ukuba ngaxa lithile kwezi nkulungwane zimbini zidlulileyo, isiseko somkhenkce siye sabuna ukusuka kumgangatho wolwandle saza sahlehla ngesantya se-1.3 yeemayile (2.1 kilometres) ngonyaka, iphinda-phinda isantya izazinzulu eziye zazibona kule minyaka ilishumi idlulileyo okanye ngoko.

Oku kuqhekeka okukhawulezayo kunokuthi kwenzeke "kutsha nje phakathi kwekhulu lama-XNUMX," u-Alistair Graham, umbhali okhokelayo wokufunda kunye ne-geophysicist yolwandle kwiYunivesithi yaseMzantsi Florida, wathi kwi-press release.

Ukwaqaphele ukuba umlambo unako ukuhlehla ngokukhawuleza kwikamva elingekude, xa sele uhle wadlula ngaphaya komqolo osezantsi elwandle onceda ukuwugcina ulungile.

"ubambe iinzipho"

URobert Larter, isazi se-geophysicist yaselwandle kunye nomnye wababhali abasebenzisanayo besifundo kwiSaveyi yaseBritane, uthe: "Umlambo ubambe iinzipho namhlanje, kwaye kufuneka silindele ukubona utshintsho olukhulu kwizikali zexesha elincinci kwixesha elizayo - nokusukela ngonyaka. unyaka – xa umlambo uwuthile.

I-Thwaites Glacier, eseWest Antarctica, yenye yezona zinkulu emhlabeni kwaye inkulu kunelizwe laseFlorida.

Kodwa yinxalenye nje yomkhenkce weWest Antarctic, equlethe umkhenkce owaneleyo wokuphakamisa umgangatho wolwandle kangangeenyawo ezili-16, ngokutsho kweNASA.
