Kudziya kwepasi kunowedzerwa nekuchengetwa kwekupisa kunoitwa nemagreenhouse gasi apo mwaranzi yezuva inokanganisa pasi pevhu. Iyi mwaranzi yezuva inowedzera tembiricha kutenderera pasirese uye inowedzerwa pamazuva akajeka.
Chidzidzo chakaitwa nevasayendisiti kubva kuInstitute of Marine Sayenzi yeCSIC chakaongorora mhedzisiro yeiyo nyowani pakuumbwa kwemakore. Ndezvipi zvine chekuita nemumwe?
Thaw weAntarctic Ocean
Sekureva kwemasayendisiti akaitisa chidzidzo ichi, kana chando chikanyungudika nekuda kwekushisa kwakanyanya chinoburitsa nitrogen yemuchadenga. Iyi nitrogen yemuchadenga inofarira kuumbwa kwemakore. Chidzidzo chakaburitsa zvidimbu zvinouya kubva kuhupenyu hushoma kwazvo hunogara mugungwa rechando uye nemvura inoitenderedza.
Sezvatinoziva, kunyungudika kwechando chemvura inotenderera pasi rese inowedzerwa nekudziya kwepasirese uye shanduko yemamiriro ekunze. Iyi nyowani inogona kufarira kuburitswa kwezvinhu zvinobatsira kuumbwa kwemakore. Iyi shanduko yanga isina kutorwa mukufungisisa chero kupi kwekunze kwemamiriro ekunze.
Kuti unzwisise chidzidzo ichi, zvinodikanwa kuti uongorore uye utore kutarisa kwepasirese nekubatana pane zvese kudyidzana pakati pegungwa, chando, mhepo uye hupenyu. Iyi michina yemamiriro ekunze yakakwana uye vanovimba neyakaenzana uye isina kugadzikana kuenzana.
Iyi data inogona kunge ichikurudzira, nekuti nekugadzirwa kuri nani kwegore, huwandu hwemwenje yezuva iyo inorova pasi pevhu inogona kudzikira, nokudaro ichipomhodza tembiricha yepasi rose. Chii chimwe, kuwedzera kunaya kwemvura kunogona kupedza kusanaya kwemvura munzvimbo zhinji dzepasi uye inofarira kukura kwehuswa, iyo, zvakare, inoisa mamiriro ekuumbwa kwemakore matsva uye inogadzira mamiriro ekunze akanaka uye mwando wakakwana.
