Nhasi, tiri kushandisa zvisaririra mafuta kuzvinangwa zvakawanda izvo, nepo ivo vachiita kuti hupenyu hwedu huve nyore, kuve neasina kudikanwa mhedzisiro mhedzisiro yekuwedzera carbon dioxide kumhepo Saka, kubvira 1980 CO2 mazinga akawedzera kupfuura 40% izvo zvakakonzera kudziya kwepasi kuwedzera.
Makungwa anopinza zvinopfuura makumi mapfumbamwe muzana ekupisa kwese, chinhu icho, nenzira isingadzivisiki, chinokonzera matambudziko mazhinji kuhupenyu huri mazviri.
Zvinoenderana nechidzidzo chakaburitswa mumagazini 'Sayenzi Kufambira Mberi', kudziya kwemakungwa kwatova pamusoro pe13% kupfuura zvaitarisirwa uye kuri kuramba kuchikurumidza. Kuti vasvike pamhedziso iyoyo, ivo vakashandisa iyo Argo flotation system, ayo ari kuyangarara anomuka nekudonha akazvimirira mumakungwa, achiunganidza tembiricha dhata pakadzika kwema 2000 metres. Kana dzangoiswa, vanotumira iyi data zvisina waya kuma satellite kuti vawedzere kuongorora.
Nokuenzanisa zviyero zvekupisa nemhedzisiro yavakaverenga kubva kumakomputa mamodheru, uye vachishandisa dhata tembiricha ichangoburwa, ivo vakakwanisa kuziva kuti mwero wekudziya mugore ra1992 unenge kakapetwa ruviri panana 1960. Izvi zvinoreva kuti kudziya kwegungwa kuri kuwedzera mumakore achangopfuura.
Vatsvagiridzi vakaona kuti nyanza dzekumaodzanyemba dzakasangana nekudziya kwakanyanya, nepo Atlantic neIndian Ocean dzakatanga kuita izvi. Zvakadaro, hapana mubvunzo kuti, sezvo tembiricha inowedzera, zvishoma nezvishoma uye zvishoma nezvishoma mativi ese epasi anozokanganiswa.
Mune chaiyo kesi yemakungwa, isu tave kutoona mhedzisiro. makorari matombo ari kuchenesa, huwandu hwekrill hwaderedzwa neanopfuura makumi masere muzanauye kune dzimwe mhuka, dzakadai sejellyfish, dzinotanga kuwanda.
Unogona kuverenga chidzidzo chakazara pano (muChirungu).
