La Antarctica. Kondinendi ine chando, ine chena yakajeka nzvimbo, sezvo nyika ichidziisa chando chayo. Iyo albedo mhedzisiro yakaita seiyi: mwaranzi yezuva inorova sinou, iyo, kana yakanyura, inorasikirwa nekusimba kwayo kusvikira yapera kuputswa negungwa.
Nechikonzero ichi, matanda ndiwo matunhu ari panjodzi yekushanduka kwemamiriro ekunze. Kana iri Antarctica, iyo tembiricha inogona kukwira kusvika pamadhigirii matanhatu panopera zana.

Mushure menguva yekupedzisira yechando, makore zviuru makumi maviri apfuura, Antarctica yakadziya kaviri kana katatu paavhareji tembiricha yepasi rose inomukaZvinoenderana neongororo yakaburitswa mune yesainzi bhuku reProceedings yeNational Academy yeSainzi, kusvika pakuti yakanyoresa tembiricha isina kujairika: 11 degrees Celsius, kana chinhu chakajairika chiri chekuti madhigirii akati wandei pazasi pe zero. Mune imwe nzvimbo yepasi, yakangowedzera ingangoita 4 degrees Celsius.
Masayendisiti akashandisa mamodheru emamiriro ekunze epasi rese ayo akashandiswa kuongorora mamiriro ekunze epasi makore zviuru makumi maviri apfuura, zvakafanana nezvakashandiswa kufungidzira kudziya kwepasi munguva inoteveraakadaro Kurt Cuffey, wekutanga munyori wekudzidza uye glaciologist kuYunivhesiti yeCalifornia, Berkeley.
Nekudaro, ivo vanokwanisa kufanotaura izvozvo nekuda kwekuchinja kuri kuita mamiriro ekunze Antarctica inozopisa zvakapetwa kaviri senyika yese; Ndokunge, kana zvichiitika kuti tembiricha yepasirese yepasi inowedzera ne3 degrees Celsius, inoenderana nemamodeli ndiyo ingangoitika, Antarctica inodziya yakatenderedza 6ºC.
Mune mamwe mazwi, kana tikasaita chero chinhu kumisa kudziya kwepasirese, mhedzisiro yeAntarctica nepasirese zvinogona kupa chinetso chikuru kune isu tese vanogara pasi rino.
