Kuya ngokwanda ukuthi iSivumelwano SaseParis ngeke sanele ukumisa ukufudumala kwembulunga yonke. Kuhloselwe ukugwema isimo sesomiso, indlala kanye nezinhlekelele zemvelo, kepha ngokusho kocwaningo olushicilelwe ku 'Nature Climate Change' olwenziwe ngabaphenyi base-University of Washington, kunethuba elingamaphesenti angama-90 lokuthi ngasekupheleni kwekhulu leminyaka izinga lokushisa elijwayelekile leplanethi yoMhlaba liyobe lenyuke phakathi kuka-2 no-5 degrees Celsius.
Lokhu kweqa umkhawulo wamadigri amabili wokuphakama asungulwe yiSivumelwano SaseParis. Ngakho-ke, kungenzeka ukuthi sikhuluma ngekusasa esingazi lutho ngalo, okukhathaza kakhulu.
Ukukhawulela ukukhuphuka kwezinga lokushisa libe yiziqu ezimbili kunethemba elikhulu. "Ukulimala kwesimo sezulu, isomiso, amazinga okushisa adlulele nokukhuphuka kwamazinga olwandle kuzoba kubi kakhulu," kuchaza uDargan Frierson, ongumbhali wombhali wocwaningo. »Imiphumela yethu ikhombisa ukuthi kuyadingeka ukwenza ushintsho olukhulu impela uma izinhloso zokwandisa kuphela izinga lokushisa ngama-1,5 degrees zizofinyelelwa.".
Ukuze benze lezi zibikezelo, abacwaningi bakhiqize ukulingiswa kwamakhompiyutha futhi babheka nesimo sezulu seplanethi, ngokwesibonelo becabangela ikhono lezilwandle ukumunca isikhutha (CO2). Ngaphezu kwalokho, idatha esetshenzisiwe enqwabelene ngaphezu kweminyaka engama-50 ukudala izimo ezisuselwa kumkhiqizo wasekhaya ophelele (GDP), ipharamitha ebala inani le-CO2 ekhishelwe idola ngalinye elikhiqizwa emsebenzini wezomnotho.
Ngakho-ke, bazama ukubikezela ukuthi kuzokwenzekani uma kungenziwa lutho ukunqanda ukufudumala kwembulunga yonke, noma uma amazwe empeleni enza imizamo yokuyeka ukushisa uphethiloli.
U-Adrian Raftery, umbhali wokuqala wocwaningo, uthe izinhloso zesivumelwano saseParis ziyiqiniso, kepha akubonakali ukuthi zizokwanela. Inani labantu ekupheleni kwekhulu leminyaka lizoba noma lizodlula abantu abayizigidi eziyi-10, ukuze kuthi, yize ukukhula kungeke kubonakale kakhulu ngoba iningi lazo lizokwenzeka e-Afrika, Ngaphandle kokuthi amazwe enze imizamo yangempela yokwehlisa ukungcola, isimo sezulu sizohluka kakhulu kunalokho esiyikho namuhla.
