Umzimba womntu uyakwazi ukuziqhelanisa: ngokuhamba kwexesha, unokubhengeza nokuba kubanda kakhulu okanye kwindawo eshushu kakhulu. Siyabulela koku, sikwazile ukwenza ikholoni phantse kuzo zonke iimbombo zomhlaba. Nangona kunjalo, asinakulibala ukuba nathi sinemida yethu.
Ukugqithisa kuyingozi kakhulu, kwaye kuya kuba yile nto iya kulawula ubomi eMhlabeni ngaphandle kokuba sikwazi ukuyeka ukufudumala kwehlabathi. Ngokophando olutsha, ngo-2050 uxinzelelo lobushushu luya kuchaphazela abantu abazizigidi ezingama-350 ngaphezulu kwale yanamhlanje.
Ingcali yezulu ekwiLiverpool iJohn Moores University egama linguTom Matthews, umbhali ophambili wophando kunye nabanye abasebenzisanayo, uhlalutye ama-44 kwezili-101 ezona “zinkulu” ehlabathini, ngaloo ndlela etyhila oko uxinzelelo lobushushu luphindwe kabini nge-1,5 degrees Celsius.
Ukuba sithathela ingqalelo ukuba ubushushu obuqhelekileyo bomhlaba kulindeleke ukuba bonyuke ngo-2ºC, ngaphezulu kwama-350 ezigidi zabantu abongezelelweyo baya kuva uxinzelelo lobushushu ngowama-2050, kuba njengoko iplanethi ifudumeza inani kunye nokuqina kwamaza obushushu nawo aya kwanda.
Ukufikelela kwesi sigqibo, abaphandi basebenzise iimodeli zemozulu kwaye bajonge indlela iingqikelelo zoxinzelelo lobushushu ezinokuluchaphazela ngayo utshintsho lobushushu. Ke, babenakho ukugqiba kwelokuba, nangona ubushushu behlabathi bunokupheliswa, izixeko ezikhulu zaseKarachi (ePakistan) naseKolkata (e-India) zinokujongana neemeko zonyaka ezifanayo nezo zafunyanwa ngo-2015, xa ubushushu babulala abantu abayi-1200 ePakistan nangaphezulu kwama-2000 XNUMX eIndiya.. Kodwa ayizukuphela kwabo.
Iidolophu ezinkulu zehlabathi zingasongelwa ngokunzulu njengoko ziqulathe isixa esikhulu seasphalt, efunxa ubushushu obenza ubushushu kwi-nucleus yedolophu buphakame kunasezilalini.
