Umkhenkce kwihlabathi jikelele uyanyibilika ngenxa yobushushu behlabathi. Okwangoku, isiciko somkhenkce sase-Ecuador yehliswe ngama-54% ukusukela ngo-1980, usuka kwi-92 yeekhilomitha ukuya kwiikhilomitha ezingama-43 ezikhoyo.
Uphando olwenziwe yi-Ecuadorian Bolívar Cáceres eQuito kwisakhelo sentlanganiso yeengcali ze-Intergovernmental Panel on Climate Change (IPCC) ityhila idatha ebabazekayo ngokunyibilika komkhenkce. Ngaba uyafuna ukwazi ngakumbi ngayo?
Ukuncitshiswa kwekhava yomkhenkce
Ibhalansi ye-glacial e-Ecuador ilinganiswa ngale ndlela ilandelayo. Zili-7 izigqubuthelo zomkhenkce ezibekwe kwiintaba-mlilo. Oku kuthetha ukuba kukho iilwimi ezili-110 zomkhenkce. Utshintsho lwemozulu luneziphumo ezibi ngakumbi kwiindawo ezahlukeneyo eMhlabeni, oko kukuthi, aluchaphazeli zonke iindawo ngokulinganayo.
E-Ecuador, iimpawu zokudlula kotshintsho lwemozulu zingaphezulu kokucacileyo xa kubonakala ukuba le ndawo ikwi-80s yayineekhilomitha ezingama-92 zesikwere somkhenkce, ngelixa okwangoku ziikhilomitha ezingama-43 kuphela.
"Besine ilahleko malunga neepesenti ezingama-54 zengqayi yomkhenkce kwisithuba seminyaka engama-60. Sisalathiso esicacileyo nesichanekileyo sendlela umkhenkce osabela ngayo kutshintsho lwemozulu ”, uqinisekisile, nangona enika umda wokuncitshiswa kwenkqubo yendalo yokwakheka komhlaba efunyanwa ziingqimba zomkhenkce zasezintabeni," ezenziwa ngabantu zikhawulezile ".
Intlanganiso ye-IPCC
Ngenxa yemeko yokunyibilika komkhenkce okusondeleyo kunye nesiphumo sokwenyuka komphakamo wolwandle kwihlabathi liphela, Iingcali ze-IPCC ezivela kumazwe angaphezu kwama-30 kwihlabathi liphela Badibene kwikomkhulu lase-Ecuador ukuba babelane ngezifundo nophando oluqhutyelwe elwandle kunye ne-cryosphere, njengezikhombisi zotshintsho lwemozulu.
Intlanganiso ibibambe izazinzulu ezili-125 ezivela kwi-IPCC kwaye abathathi-nxaxheba bebesenza uphando lwabo kuyo yonke iveki kulwandle nakwisibhakabhaka. I-cryosphere yinxalenye yomphezulu womhlaba apho amanzi akwimo eqinileyo efana nomkhenkce wolwandle okanye umkhenkce omkhenkce, kwaye ezo zinto zibalulekile kwindalo yohlalutyo lwemozulu kwaye kuxhomekeke kuluntu.
Umba wolwandle kunye ne-cryosphere kuye kwaba sisiseko kuphando oluninzi kwihlabathi liphela, enkosi kwinto yokuba zibonisa ngokucacileyo ukuba utshintsho lwemozulu luchaphazela njani ngendlela engeyiyo.
Ingxelo kulindeleke ukuba ipapashwe ngo-Epreli walo nyaka kwaye izokunceda oorhulumente bathathe izigqibo xa besenza imigaqo-nkqubo esekwe kwisayensi encedisa ukwenziwa kobutyebi kwimeko yokutshintsha kwemozulu.
Inkqubela phambili ekhawulezayo yobushushu behlabathi
U-American Ko Barret, usekela-mlawuli woPhando ku-National Oceanic and Atmospheric Administration (NOAA) kunye neshumi elinesihlanu leminyaka elilungu elikhutheleyo le-IPCC awayelisekela mongameli, uqinisekisile ukuba ubushushu bomhlaba yinto ebonakalayo kwaye okwangoku akunamsebenzi ukuyiphika .
“Ewe kukho ukufudumala, zonke izifundo kuthotho lweminyaka engamashumi amathathu edlulileyo zibonisa inkqubela yobushushu yomhlaba wonke", Ugcina phambi koososayensi abathile abathi kukho iindawo apho kwenzeka into echaseneyo.
Imiba ejongiwe zizazinzulu malunga nokufudumala kwehlabathi izama ukugubungela kangangoko kunokwenzeka, ukusuka encotsheni yeentaba zomkhenkce ukuya ezinzulwini zolwandle.
Eminye yemimandla esesichengeni sokutshintsha kwemozulu, enje ngemimandla yeArctic kunye neendawo eziphakamileyo zeentaba, kufuneka ifundwe nzulu, kuba ukuncitshiswa komkhenkce kunokuba yingxaki ngenxa yokunyuka komgangatho wolwandle isikali sehlabathi. Le yimimandla ejikeleze umhlaba wonke efumana utshintsho olucacileyo oluguqula zonke iimeko ezibonwe kwada kwaba yiminyaka engama-50 eyadlulayo.
Njengoko ubona, umkhenkce omkhenkce wase-Ecuador uyanyibilika kwizinga elikhawulezayo kwaye oku kuya kuba neziphumo ezibi kungekudala.
