Ukuba ixesha elithile elidlulileyo kwi blog Besithetha malunga nokuba, ngenxa yokunyuka kwamaqondo obushushu emhlabeni, ukuhamba ngenqwelomoya kunokuba sisiphithiphithi kunesiqhelo, isifundo esitsha esipapashwe kwijenali yeClimatic Change sibonisa ukuba kumashumi eminyaka ezayo kuya kuba nzima ngakumbi ukuthatha uhambo.
Kwaye, ukuba uyafuna ukuyenza, kuya kufuneka uhambe nobunzima obuncinci; Ngaphandle koko inqwelomoya iya kulibaziseka okanye irhoxisiwe. Ngoba?
Njengoko umoya ushushu, uyasasazeka kunye nokuxinana kwawo kuyancipha. Ngenxa yokuba ikhaphukhaphu, amaphiko avelisa into ephakamisa kancinci xa inqwelo moya ihamba ecaleni komgaqo weenqwelo moya. Ke ngoko, kuxhomekeke ngaphezulu kwayo yonke imodeli yenqwelomoya kunye nobude bomgaqo ngokwawo, phakathi kwe-10 kunye ne-30% yeenqwelomoya ezilayishiwe aziyi kuba nakho ukusuka ukuba amaqondo obushushu aphezulu kakhulu.
Umbhali okhokelayo kufundo u-Ethan Coffel, Ph.D. ovela kwiDyunivesithi yaseCalifornia, uthe, "Iziphumo zethu zibonisa ukuba ukuthintelwa kobunzima kunokubangela Iindleko ezingabalulekanga kwiinqwelomoya kunye nefuthe kwimisebenzi yokuhamba ngenqwelomoya emhlabeni jikelele".
Iqondo lobushushu lehlabathi liphela linokunyuka liye phezulu I-3 degrees Celsius ngonyaka wama-2100, Okwangoku, amaza obushushu aya kuba rhoqo, ngamaqondo obushushu aphezulu i-4 ukuya kwi-8 degrees ephezulu kunesiqhelo ukuqala ngo-2080. La maza obushushu ngawona aya kuthi abangele ezona ngxaki kwilizwe eliya lixhuma.
Yiyo loo nto, ukuba ukukhutshwa kwegesi eluhlaza kunganciphiswanga, Umthamo wepetroli kunye nobunzima bokulayisha kuya kufuneka bucuthwe ukuya kuthi ga kwi-4% kwezona ntsuku zishushu kwezinye iinqwelomoya. Kwimeko apho bancitshiswe babancinci, kwaye kungekudala, kuyakufuneka kuphela ukunciphisa ubunzima nge-0,5%, ngokophando.
