Ukushintsha kwesimo sezulu

Yilokho ucwaningo olushicilelwe ephephabhukwini lesayensi i-Nature lwembula: ukushintsha kwesimo sezulu kwamanje kwaqala eminyakeni eyi-180 eyedlule, cishe ama-80 ngaphambi kokukholwa kuze kube manje. Abantu bahlale belungisa imvelo esiphila kuyo thina, kepha kuze kwaba unyaka we-1830 lapho iplanethi yaqala ukuhlupheka, okusho ukuthi, kwi-First Industrial Revolution.

Kusukela lapho, amagesi abamba ukushisa aqoqene emkhathini, futhi sesifike ezingeni lapho ibhalansi yemvelo yoMhlaba iphuka khona, uma ingakavele yephukile. Khumbula ukuthi izinguquko zesimo sezulu bezilokhu zenzeka, kepha manje abantu sebekwazi ukuzenza zibe zimbi kakhulu.

Ukugawulwa kwamahlathi, ukuqiniswa okuqhubekayo kwemfuyo, kanye nokusetshenziswa kwamafutha ezimbiwa kuphakathi kwezimbangela ezinkulu zokwanda kokukhishwa kwegesi engcolisa umoya, njengeCarbon dioxide noma i-CO2. Kepha, Ngabe abacwaningi bazi kanjani ukuthi ukuguquka kwesimo sezulu kwanamuhla kuqale ngaphambi kokucabanga kwangaphambilini?

Ukwazi, baqoqa ubufakazi obungaqondile bokushisa kweplanethi kusuka ezintweni ezahlukahlukene ezindaweni ezahlukahlukene, njengokuqoqa amasampula wamasongo ezihlahla, izinsalela zamakhorali, ama-ice cores okuyimigoqo yamanzi afriziwe akhishwa izinguzunga zeqhwa, nezinye izinto ukwazi ukuthi isimo sezulu sasinjani ngosuku oluthile, nokuthi isikhutha kwaba.

Ukushisa kakhulu komhlaba

Njengokulangazelela, uBelén Martrat, usosayensi e-CSIC Institute for Environmental Diagnosis and Water Studies, »ukufudumala ezindaweni ezishisayo kwaqala cishe ngesikhathi esifanayo nase-Arctic', Cishe ngawo-30 wekhulu le-1815. Kuze kube yileso sikhathi, uMhlaba ubudlule esikhathini sokuphola ngenxa yokuqhuma kwentaba-mlilo, njengeTambora e-Indonesia ngo-1816, okwenza ukuthi ngo-XNUMX kwakungekho ihlobo.

Akucaci ukuthi ukukhuphuka kwe-First Industrial Revolution kanye nokuphela kwesikhathi sokupholisa kumane kwaqondana nesikhathi noma ukuthi lokho kwadala lesi simo, kepha ababhali bezocwaningo bakholelwa ukuthi ukwanda kokuxinana kwamagesi abamba ukushisa kuhlobene yomibili imicimbi.
