Antarctica ndeimwe yenzvimbo uko mhedzisiro yeshanduko yemamiriro ekunze iri kunzwika zvakanyanya. Kubata ndeimwe yematambudziko anonetsa, kwete chete nekuti zvinokanganisa nzira yehupenyu yevagari vekondinendi, asiwo nekuti kukwira kwenzvimbo yegungwa kungave nemhedzisiro pasirese.
Iye zvino, mukuwedzera, vaongorori veA ARC Center yeKwakanaka kweClimate System Sainzi vakawana izvo mhepo kuEast Antarctica dzinogona kuunza nyonganiso mugungwa dzinoparadzirwa kuburikidza nemafungu eKelvin, ayo ari mhando yemafungu egungwa.
Kelvin anozunguzira pavanosangana nemamiriro epasi pemvura ekumabvazuva kweAntarctic Peninsula, Sundira mvura inodziya pamasherufu mahombe echando pamhenderekedzo yegungwa. Iyo Antarctic circumpolar inodziya yazvino inopfuura padyo neshelffu renyika, iyo inosanganisirwa nekutakurwa kwemvura inodziya pamusoro pechando kumberi, kuri kukonzera kunyungudika kwenzvimbo yekumadokero kweAntarctic kuti ikurumidze.
Shanduko mumhepo dzemahombekombe munzvimbo ino yepasi dzinogona kuve zvine chekuita nekushanduka kwemamiriro ekunze, kubvira Sezvo tembiricha yepasirese inokwira, mhepo dzakasimba dzekumadokero dzakabatana nemadutu pamusoro peSouth Ocean kupisa, zvichikonzera shanduko mumhepo padyo neAntarctica.
Kubhururuka kwekondinendi inyaya inoshungurudza. Na 2100, mwero wegungwa unogona kukwira kudarika mita imwe, uye ne2500, anopfuura gumi nemashanu mamamita pasi pechizvino shanduko yegreenhouse gasi inoburitsa. Naizvozvo, vaongorori vanotenda kuti tinofanirwa kutora matanho nekukurumidza kumisa kudziya kwepasirese, nekuti kana tikadaro, »nzira dzekumaodzanyemba dzemafashama dzinogona kudzokera kunzvimbo yekuchamhembe, izvo zvinogona kudzikisira kunyungudika muWest Antarctica. Izvo zvinogona zvakare kudzikamisa kudziya kwemakungwa uye kupa mukana wekudzikamisa mamwe emahombe mahombe echando anoperera mugungwa.
