Ukufudumala kwehlabathi, yintoni elandelayo?

Iingcali kwi-Intergovernmental Panel on Climate Change zigxininise isidingo sokuba ihlabathi liqalise iinguqu "ezikhawulezayo nezingazange zibonwe ngaphambili" ukuba zinciphisa ukufudumala ukuya kwi-degrees Celsius kunye nesiqingatha, isilumkiso sokunyuka kweengozi ukuba eli nqanaba lidlulile.

Kwingxelo yamaphepha angama-400, isishwankathelo salo sapapashwa ngoMvulo, izazinzulu zazisa "kubenzi bezigqibo bezopolitiko" iziphumo ezininzi ezaqala ukubonakala, ngakumbi ukufudumala okungaphezulu kwe-degrees Celsius enye enesiqingatha, xa kuthelekiswa nenqanaba. kwixesha langaphambi kwamashishini. Phakathi kwezi ziphumo, amaza obushushu, ukuphela kweentlobo zezilwanyana kunye nokunyibilika kwe-ice cap ye-polar, kunye nokunyuka okulandelayo kwinqanaba lolwandle kwixesha elide.

Ukuba iqondo lokushisa liyaqhubeka nokunyuka kwisantya sangoku ngenxa yokukhutshwa kweegesi ze-greenhouse, ukunyuka kulindeleke ukuba kufikelele kwi-degrees Celsius enye enesiqingatha phakathi kwe-2030 kunye ne-2052, ngokutsho kwengxelo, esekelwe kwizifundo ezingaphezu kwamawaka amathandathu.

Yaye ukuba amazwe anelisekile zizibhambathiso zawo zokunciphisa oku kukhutshwa kwezinto ezikhutshwa kwiSivumelwano saseParis esigqitywe ngowama-2015, ubushushu buza kunyuka ngamaqondo amathathu ekupheleni kwale nkulungwane.

Ukuze kuncitshiswe ukufudumala ukuya kwiqondo elinesiqingatha, iKomishoni yeMozulu ithathele ingqalelo ukuba ukukhutshwa kwekharbon diokside kufuneka kunciphe nge-45% ngonyaka ka-2030 kwaye umhlaba kufuneka ufikelele kwi-"carbon neutralization", oko kukuthi, ubungakanani obukwi-atmosfera. zingagqithi kwezo zinokurhoxiswa kuyo.

Le ngxelo icele onke amacandelo ukuba "anciphise kakhulu ukukhutshwa kwezinto ezikhutshwayo ngokukhawuleza nangendlela engazange ibonwe ngaphambili".

Igunya ligxininise ukuba imithombo yamandla, ngakumbi amalahle, igesi kunye ne-oyile, inoxanduva lwekota ezintathu zokukhutshwa.
