Iminyaka eyishumi yokulwa nemiphumela yokushisa komhlaba

IPlanethi yoMhlaba ebonwa emkhathini

IPlanethi enguMhlaba njengoba sazi namuhla ngumhlaba lapho umthelela womuntu emvelweni mkhulu kakhulu kangangokuba sikwazile ukwephula ibhalansi yemvelo yekhaya lethu. Manje, ngokusho kocwaningo olwenziwe yi-International Institute for Applied Analysis Systems (IIASA) sineminyaka eyishumi kuphela ukulwa nemiphumela yokushisa komhlaba, ngaleyo ndlela kugwenywa ukuthi izinga lokushisa elijwayelekile likhuphuka ngaphezu kuka-2ºC.

Uma singenzi lutho, imiphumela ingaba engalindelekile.

Ngokwesifundo, ngamafutha ezinto ezimbiwa phansi angama-2100 kufanele anikeze kuphela amaphesenti angama-25 wamandla okudingwa yimboni. Namuhla umnotho womhlaba uncike kuma-95% alo mandla. Lokhu kusho ukuthi uma singaqali ukusebenzisa futhi sisebenzise amandla avuselelekayo amaningi, ahlanzeke kakhudlwana, sizogcina sesihlala kwiplanethi efudumele kakhulu. Ukuze ucacise, cishe ukufudumala okungu-3,5ºC.

UMichael Obersteine, ongumbhali ngokubambisana ocwaningweni, ukusho lokho kufanele kuthathwe izinyathelo zokunciphisa ukukhishwa kwe-carbon dioxide okubangelwa imisebenzi yabantu kuze kube zero ngo-2040, ngaphandle kwalokho asikwazanga ukugcina izinga lokushisa lingaphansi kuka-2ºC.

Ukungcoliswa komoya

I-IIASA incoma ukuthi wonke umuntu azi ukuthi kubaluleke kangakanani unakekele umhlaba nemvelo ukuze kuthi ekupheleni kwaleli khulu leminyaka ukukhishwa kwekhabhoni kwehle kuye kumaphesenti angama-42, okuzosebenza kakhulu ekuqedeni imiphumela yokufudumala kwembulunga yonke. Yize kunjalo, wengeze wathi lesi simo sibi kangangokuba noma ngabe kuthathwa izinyathelo zokuvikela imvelo, amazinga okushisa ngo-2100 azokwenyuka ngo-2,5ºC.

Mhlawumbe sekuyisikhathi sokucabanga ngalokho ebesikwenza kuze kube manje, nokuthi yini esisenaso isikhathi sokwenza.
