Ishumi leminyaka lokulwa nefuthe lobushushu behlabathi

Umhlaba ubonwa emajukujukwini

IPlanethi yoMhlaba njengoko sisazi namhlanje lihlabathi apho ifuthe lomntu kwindalo esingqongileyo likhulu kangangokuba siye sakwazi ukwaphula ibhalansi yendalo yekhaya lethu. Ngoku, ngokophando olwenziwe liZiko laMazwe ngaMazwe leNkqubo yoHlahlelo oluSebenzayo (IIASA) sineshumi leminyaka kuphela lokulwa nefuthe lobushushu behlabathi, kuthintelwa ukuba iqondo lobushushu eliphakathi lenyuke ngaphezulu kwe-2ºC.

Ukuba akukho nto siyenzayo, iziphumo zinokungaqiniseki.

Ngokophando, ngamafutha e-fosili angama-2100 kufuneka anikeze kuphela iipesenti ezingama-25 zamandla into efunwa lishishini. Namhlanje uqoqosho lwehlabathi luxhomekeke kwi-95% yala mandla. Oku kuthetha ukuba ukuba asiqali ukusebenzisa kwaye sisebenzise amandla ahlaziyekayo ngakumbi, acoceke kakhulu, siyakuphela sihlala kwiplanethi eshushu kakhulu. Ukucacisa ngakumbi, malunga ne-3,5ºC ishushu.

UMichael Obersteine, umbhali-mbhali wesifundo, wathi Amanyathelo kufuneka athathwe ukunciphisa ukukhutshwa kwekhabhoni dayoksayidi ebangelwa yimisebenzi yabantu ukuya kwi-zero ngo-2040Ngaphandle koko asikwazi ukugcina ubushushu bungaphantsi ko-2ºC.

Ungcoliseko lomoya

I-IIASA icebisa ukuba wonke umntu abenolwazi lokuba kubaluleke kangakanani khathalela umhlaba nokusingqongileyo Ukuze kuthi kuphela ukuphela kwale nkulungwane ukukhutshwa kwekhabhoni kwehle ukuya kwiipesenti ezingama-42, eziza kuthi ziphumeze ubukhulu becala iziphumo zobushushu behlabathi. Wongeze ukuba le meko imbi kangangokuba nokuba kuthathwa amanyathelo okukhusela okusingqongileyo, amaqondo obushushu ngo-2100 azonyuka ngo-2,5ºC.

Mhlawumbi lixesha lokuba sicinge ngale nto besiyenza ukuza kuthi ga ngoku, kwaye sisenexesha lokwenza.
