Tsvagiridzo inotungamirwa neAmerican space agency inoratidza, kuburikidza nedhata resatellite, kuti chiitiko ichi chakaitika mukati menguva yese yakaongororwa, kubva 1992 kusvika 2008, paive mambure kuwana kwe112 bhiriyoni matani echando. IInotodenha zvimwe zvidzidzo, senge sangano reIntergovernmental on Climate Change (IPCC 2013), iro rakati kondinendi iri kukuvadzwa nekudziya kwepasi.
Kuwanikwa hakurevi, zvisinei, kuti kudziya kwepasi hakupo, kunongoramba pfungwa yekuti kunobatsira pakunyungudisa polar ice caps, kuwedzera mwero wemakungwa, sekureva kweNASA, nekuda kwekuwana iyi ice, the chiyero chemakungwa chinodzikiswa ne0,23 mm pagore - inenge hafu yemasentimita mumakore makumi maviri.
"Isu tiri kubvumirana nezvimwe zvidzidzo zvinoratidza kuwedzera kwekunyunguduka kwechando munzvimbo yeAntarctic Peninsula, kuPine Island neThwaites, iyo iri kumadokero," akadaro Jay Zwally, nyanzvi yeglaciologist kuNASA uye munyori mukuru we chidzidzo chitsva, chinoti "kusawirirana kwedu kukuru kune chekuita neEast Antarctica uye mukati meWest Antarctica.

Mune mamwe mazwi, kuwedzera kwechando hakusi yunifomu, seAntarctica inoshanda nenzira inotevera: chikamu chechando chinokandwa mugungwa, kana zvivharo zvakakura zvakavharwa, zvishoma nezvishoma zvinonyunguduka uye zvinodzoka nenzira yekunaya. Dai paive nechando chakawanda chaibuda pane kupinda, tingadai tine dambudziko, asi zvinofadza, handizvo. Sezvineiwo.
