Nenzvimbo ingangoita zviuru zvishanu zvemakiromita, pasherufu yechando inozivikanwa seLarsen C ice shefu yave kuda kutsemuka. Iko kutsemuka kwatova neinenge 110km kureba, 100m yakafara uye ingangoita 500m yakadzika, uye sekuratidzwa kweiyo Svondo, inoita kunge inobatwa pamwechete neshinda yechando.
Masayendisiti anotarisira kuti ichadeurwa zvizere mumwedzi iri kuuya. Asi nei?
Ichando cheAntarctica chakanamirwa pasherufu rekondinendi, uye kwete pamvura senge muArctic. Neichi chikonzero, apo mwero wegungwa unokwira pasi rose. Iyo Larsen Ice Shelf, iri panzvimbo yekumabvazuva kwemahombekombe eAntarctica, inoshanda semudziyo wemazaya echando. Nehurombo, iyo Larsen A uye B zvikamu zvakatobviswa, muna 1995 na2002 zvakateerana.
Maererano nekuverenga kwesainzi, dai chando chose chaizobudikira pamusoro pegungwa chaizokwira nemasentimita gumi. Zvinogona kunge zvisingaite kunge zvakawanda, asi vese avo vaigara kumahombekombe vanotanga kuve nematambudziko akawanda.
Sezvo tembiricha yepasirese yepasi rose inokwira, chando muAntarctica chiri kunyungudika, izvo zvinongowedzera mamiriro acho ezvinhu. Panyaya iyi, zvinoenderana ne Nature magazini kudzidza, inoitiswa nevanoongorora Robert M. DeConto, kubva kuDhipatimendi reGeosciences paUniversity yeMassachusetts (United States), naDavid Pollard vanobva kuPennsylvania State Institute (United States), pagore 2100 huwandu hwemvura hunogona kukwira kudarika mita imwe.
Kungoti kana gasi yekupisa gasi inogona kudzikiswa, nyungudika yaizopa zvishoma kudiki mukukwira kwemwero wegungwa, akadaro Professor DeConto.
