Utshintsho lwemozulu

Yiloo nto isifundo esapapashwa kwijenali yesayensi indalo ityhila: Ukutshintsha kwemozulu kwangoku kwaqala kwiminyaka eyi-180 eyadlulayo, phantse ngama-80 ngaphambi kokuba ikholelwe kude kube ngoku. Abantu bahlala behlengahlengisa imeko-bume esihlala kuyo, kodwa kwade kwangunyaka we-1830 apho iplanethi yaqala ukubandezeleka, oko kukuthi, kwi-First Industrial Revolution.

Ukusukela ngoko, ii-greenhouse gases ziye zaqokelelana emoyeni, kwaye sifikelele kwinqanaba apho ulungelelwano lwendalo loMhlaba luqhekeka, ukuba alukaphuli. Gcina ukhumbula ukuba utshintsho lwemozulu luhlala lusenzeka, kodwa ngoku abantu banakho ukubenza mandundu.

Ukupheliswa kwamahlathi, ukuqiniswa okuqhubekayo kwemfuyo, kunye nokusetyenziswa kwezibaso zezinye zezona zinto zibangela ukwanda kokukhutshwa kwegesi ekhulisa ubushushu, njengekharbon diokside okanye i-CO2. Kodwa, Baye bazi njani abaphandi ukuba utshintsho lwemozulu yanamhlanje luqale kwangoko kunokuba babecinga ngaphambili?

Ukwazi, uqokelele ubungqina obungangqalanga beqondo lobushushu beplanethi kwizinto ezahlukeneyo kwiindawo ezahlukeneyo, ezinje ngokuqokelela iisampulu zemisesane yomthi, intsalela yekorale, iindawo zomkhenkce eziyimivalo yamanzi afriziweyo akhutshwe kwizikhenkcezisi zomkhenkce, kunye nezinye izinto ukwazi ukuba imozulu yayinjani ngomhla othile, kwaye ikharbon diokside yayinayo.

Ubushushu bukazwe lonke

Njengomdla, uBelén Martrat, isazinzulu kwiZiko le-CSIC lokuchonga okusingqongileyo kunye nezifundo zamanzi, »Ukufudumala kwiindawo ezitshisayo kwaqala malunga nexesha elifanayo ne-Arctic', Ngama-30s wenkulungwane ye-1815. Kuze kube ngumzuzu, uMhlaba uhambe ngexesha lokupholisa ngenxa yokuqhuma kwe-volcanic, njengeTambora e-Indonesia ngo-1816 eyabangela ukuba ngo-XNUMX kwakungekho ihlobo.

Akucaci ukuba ukunyuka koQhushululu lokuQala lwezoRhwebo kunye nokuphela kwexesha lokupholisa kungqamene nexesha okanye ukuba eyokuqala ibange le meko, kodwa ababhali abafundayo bakholelwa ukuba ukwanda koxinaniso lweegesi zegreenhouse ezinxulunyaniswe yomibini le misitho.

      Sawande Alejandro.
      Utshintsho lwemozulu luhlala luhleli kwaye luya kuhlala lukhona. Ingxaki yeyokuba akuzange ngaphambili kubekho iintlobo ezifana nezethu ezinakho ukutshabalalisa imeko-bume apho zihlala khona, ke ngekhe sazi ngokuqinisekileyo ukuba kuya kwenzeka ntoni kuba singabokuqala ukuba nefuthe elikhulu kangaka emhlabeni.
      A ubingelele.
