Iya isanda into yokuba isiVumelwano saseParis asisayi kwanela ukumisa ubushushu behlabathi. Kujongwe ukuba kuthintelwe imeko yembalela, indlala kunye neentlekele zendalo, kodwa ngokophando olupapashwe kwi 'Nature Climate Change' olwenziwe ngabaphandi beDyunivesithi yaseWashington, kukho ithuba lama-90 eepesenti lokuba ekupheleni kwenkulungwane ubushushu obuqhelekileyo bomhlaba buza kube bonyuke phakathi kwe-2 kunye ne-5 degrees Celsius.
Oku kungaphezulu komda weedigri ezimbini zokunyuka esekwe sisiVumelwano saseParis. Ke ngoko, sinokuthetha ngekamva esingazi nto kwaphela ngalo, elixhalabisa kakhulu.
Ukunciphisa umda kumaqondo obushushu ukuya kwiidigri ezimbini kunethemba kakhulu. "Umonakalo osuka kwimozulu yezulu, imbalela, amaqondo obushushu agqithisileyo kunye nokunyuka kwamanqanaba olwandle kuya kubanzima kakhulu," ucacise watsho umbhali-mbhali uDargan Frierson. »Iziphumo zethu zibonisa ukuba kunyanzelekile ukuba senze utshintsho olukhulu ekhosini ukuba iinjongo zokwandisa ubushushu nge-1,5 degrees ziya kufezekiswa.».
Ukuze benze olu qikelelo, abaphandi baphuhlise ukulinganisa kweekhompyuter kwaye benza uqikelelo lwemozulu yesijikelezi-langa, umzekelo kuthathelwa ingqalelo amandla olwandle ukufunxa icarbon dioxide (CO2). Ukongeza, idatha esetyenzisiweyo eqokelelwe ngaphezulu kweminyaka engama-50 ukwenza iimeko ngokusekwe kwimveliso yekhaya (GDP), ipharamitha ebala inani le-CO2 ekhutshelwe idola nganye eveliswa kwimisebenzi yezoqoqosho.
Yiyo loo nto, bezama ukuqikelela ukuba kuya kwenzeka ntoni ukuba bekungekho nto iyenziwayo ukunqanda ukufudumala kwehlabathi, okanye ukuba amazwe enze iinzame zokuyeka ukutshisa izibaso.
U-Adrian Raftery, umbhali wokuqala kolu phononongo, uthe iinjongo zesi siVumelwano saseParis ziyinyani, kodwa akubonakali ngathi ziya kwanela. Abemi ekupheleni kwenkulungwane bazakuba okanye bazakugqitha kwizigidi ezili-10 zabantu, ukuze, nangona ukukhula kungazukuqapheleka njengoko uninzi lwayo luzakwenzeka eAfrika, Ngaphandle kokuba amazwe enze iinzame zokwenyani zokunciphisa ukukhutshwa kobushushu, imozulu iya kwahluka kakhulu kunanamhlanje.
