Pfupisa nyaya yacho:  Kupisa kwenyika hakuna kuitika nokukurumidza sezvinotarisirwa, maererano nefundo itsva yakavakirwa pamakore 1 000 ezvinyorwa zvechando. Tsvakurudzo yacho inotaura kuti kuchinja-chinja kwemamiriro okunze kwepasi mukati memakore gumi kunogona kukonzera kuwedzera uye kuderera kwemwero wokudziya kwepasi. Asi rinowedzera kuti izvi zvinonzi 'kuchinja-chinja kwemamiriro okunze' zvinogonawo, munguva yemberi, kuita kuti pasi redu ripise nokukurumidza zvikuru kupfuura zvinotarisirwa. Dzorera pasi kuti uone vhidhiyo. Chidzidzo chacho chakaenzanisa migumisiro yacho nezvakanyanya kukanganisa zvinokonzerwa nemhepo zvakatsanangurwa neIntergovernmental Panel on Climate Change (IPCC). Zvisinei, fundo yazvino uno inotaura kuti uyu muenzaniso wemamiriro okunze ungave usina kururama. Chidzidzo chacho chakaenzanisa migumisiro yacho nezvakanyanya kuipa zvinobuda mumhepo zvakatsanangurwa neIntergovernmental Panel on Climate Change (IPCC). 'Maererano nokuongorora kwatakaita, zviri pachena kuti mamiriro okunze achangotanga kudziya, panguva ino,' akadaro Patrick Brown, mudzidzi ari kuita dhigirii rokudzidza nezvezvakatipoteredza paDuke University. 'Asi izvi zvingachinja.' Kudzidza kwakatungamirirwa naDuke kunotaura kuti kuchinja-chinja kunokonzerwa nokudyidzana kuri pakati pegungwa nemhepo, uye zvimwe zvinhu zvomusikirwo. Vanoti 'kuchinja-chinja' uku kunogona kuderedza kana kuti kukurumidzisa mwero wokudziya kwepasi kubva pamakore gumi kusvika kumakumi gumi, uye kuwedzeredza kana kuti kuderedza migumisiro yokuwedzera kwemhepo inopisa. Kana dzikasatsanangurwa uye dzikasanyatsoongororwa, dzinogona kukanganisa kuvimbika kwemienzaniso yemamiriro okunze uye kutungamirira pakunyanyisa kududzira zvinoitika munguva pfupi. Pfupiso yezvinotarisirwa kuchinja kwezvibereko zvezvirimwa muIPCC yapfuura. Nemhaka yokuti 'kuchinja-chinja kwemamiriro okunze' kwakanga kusingabatanidzwi, vatsvakurudzi veDuke University vanoti mushumo wacho ungave wakanga uri kududzira zvisina kufanira zvinoitika munguva pfupi mumamiriro okunze. Tsvakurudzo yacho, inoshandisa mashoko akacherechedzwa, panzvimbo pemhando dzemamiriro okunze dzinowanzoshandiswa, kuti ifungidzire kuchinja kwemakumi emakore. 'Panguva ipi neipi yakati, tingatanga kudziya nokukurumidza zvikuru kana mwero wegasi rinopisa mumhepo yakapoteredza pasi ukawedzera pasina kuchinja kupi nokupi mumwero weaerosol...
Kudzidza kwakaitwa paDuke University kwakaongorora makore 1 000 enhoroondo dzetembiricha. Rakaenzanisa izvi nezvakaipisisa zvinotaurwa neIPCC. Vakawana kuti kushanduka kwechisikigo kunogona kunonoka kana kukurumidzisa mwero wokudziya. Aya 'kuchinja kwemamiriro okunze' haana kunyatsoongororwa mushumo weIPCC.
