Njengokuba besesixoxile kwizihlandlo ezininzi, utshintsho lwemozulu lwonyusa ukuphindaphindeka kunye nokuqina kweziganeko zemozulu ezigabadeleyo ezinje ngembalela, izikhukula kunye neenkanyamba.
Ekuqaleni kwenyanga, iNkanyamba uIrma yahlasela iCaribbean yaza yabangela umonakalo omkhulu. Izaqhwithi zondla amandla akhutshwa elwandle. Ke ngoko, ngokunyuka kwamaqondo obushushu abangelwe kukutshintsha kwemozulu, izazinzulu zikholelwa ukuba ziya kunyuka ngamandla ngakumbi, nangona kunjalo, ngekhe zenze njalo rhoqo. Zazinokuba namandla kangakanani ezo nkanyamba?
Ukwanda kwenkanyamba
Ukungabikho kwedatha yesathelayithi yedatha ngaphambi kowe-1970, akunakwenzeka ukuba wazi njani ukuba imisebenzi yecyclonic yavela njani kwinkulungwane ye-XNUMX. Phambi kofakelo lokulandela umkhondo opheleleyo wesathelayithi, nkqu neenkanyamba ezinamandla kakhulu zinokungaziwa ukuba azenzanga umhlaba, umzekelo. Yiyo loo nto ubulumko bezazinzulu.
Ngokungafaniyo nedatha yemvula njalo njalo, iinkanyamba kufuneka zijongwe esithubeni ngeesathelayithi kwaye zibekwe iliso. Emva kovavanyo olwenziwe ukusukela ngo-1970, ukwanda kokuphindaphindeka kwenkanyamba kwaqwalaselwa kangangeminyaka engama-20, ngokungafaniyo phakathi ko-1970 no-1995.
Ukuphakama okuphezulu kwezaqhwithi
Kunzima ukuqikelela ukuba inani leenkanyamba ezenzeka kwiplanethi yethu kungenxa yokwahluka kwendalo okanye utshintsho lwemozulu, ngenxa yedatha ekhoyo ekhoyo namhlanje. KwiPacific Northwest babekhona ukwehla okuncinci kwimisebenzi yokujikeleza phakathi kuka-1980 no-2010.
Nangona kunjalo, iimodeli zekhompyuter ezisebenza ukulinganisa imozulu eziza kuba kuyo le nkulungwane, zityhila ukwanda okunokubakho kumandla enkanyamba, ngamandla amakhulu kwimimoya nakwiimvula, kunye nokwehla okunokwenzeka kubuninzi babo kwiplanethi.
“Iinkanyamba ezinamandla ngakumbi zezinye zeziphumo ezilindelekileyo zotshintsho lwemozulu. Ukuphakama kobushushu bamanzi kunye nenqanaba lokufuma, kokukhona amandla enkanyamba angabakho. Nangona kunjalo, ezi zinto zimbini zinamandla ngakumbi ngenxa yokwanda kwempembelelo yendlu eluhlaza ”, ucacisa uValérie Masson-Delmotte, olilungu le-GIEC, iqela ekubhekiswa kulo kwimozulu.
Kukho i-7% yomswakama ngakumbi emoyeni kuwo onke amanqanaba vumela iplanethi ifudumale. Ke ngoko kufuneka sazi ngobunzulu beenkanyamba ezilandelayo.
