Njengoko sele sidwelisile kumaxesha amaninzi, utshintsho lwemozulu lubangela ukwanda kwamaqondo obushushu echaphazeleka kakhulu kwindawo yeepali. Qho ngonyaka amaqondo obushushu aphakathi aphezulu kwaye abangela umonakalo omkhulu kwezo ndawo ziphila nezona zisengozini. EGreenland kokokuqala ukuba kubhalwe into enje. Kwaye ingo-Agasti 14 odlulileyo yaqala ukunetha kweyona ndawo iphakamileyo yomkhenkce. Kungenxa yokuba ubushushu bomoya bukwazile ukuhlala ngaphezulu kwengqele kangangeeyure ezisithoba.
Kule nqaku siza kukuxelela ukuba kutheni lo msitho wenzekile kwaye zinokuba yintoni iziphumo.
Iyana imvula eGreenland
Ukwanda kwamaqondo obushushu aphakathi kwiplanethi yonke kubangela umonakalo omkhulu kwezo ndawo zibuthathaka kakhulu kubushushu. Njengokuba, indawo yezibonda ihlala isesichengeni kutshintsho lobushushu. Njengoko sibonile kwizihlandlo ezininzi, uLwandlekazi lweArctic luphelelwa ngumkhenkce. Oku kuchaphazela ngokungagungqiyo izilwanyana ezifuna umkhenkce ukuze zisinde kuba iyinkqubo yendalo. Ngapha koko, siyazi ukuba kukho ulungelelwaniso kwiwebhu yokutya ezinokuphila ngayo izilwanyana.
Ngenxa yokunyuka kwamaqondo obushushu oku kulingana kuyaqhekeka. Kokokuqala ukuba into enje irekhodwe ukusukela oko kubhalwa amaqondo obushushu. Kwaye kunjalo Nge-14 ka-Agasti ka-Agasti, yaqala ukuna kweyona ndawo iphakamileyo yeGreenland. Oku kubangelwe bubushushu bomoya ukukwazi ukuhlala ngaphezulu kwengqele kangangeeyure ezisithoba. Oku kuyenza okwesithathu kwisithuba esingaphantsi kweshumi ukwenzeka oku.
Ngamaqondo obushushu angaphantsi kwe-zero nangaphezulu kwe-3.200 yeemitha zokuphakama, iimeko kwingqungquthela yeGreenland Azihlali zikhokelela kwimvula ngohlobo lwamanzi kodwa ngekhephu. Ke ngoko, le nto ibalulekile.
Idayisi malunga nomsitho
Ngokwedatha evela kwiZiko laseMelika laseMelika leSiqhwa kunye neQhwa (i-NSIDC), ubungakanani bokunyibilika kwe-ice sheet kwenyuka ngo-Agasti 14 kwizikwere zeekhilomitha ezingama-872.000. Ngosuku olulandelayo emva kwesi siganeko, i-ice sheet yayisele ilahlekelwe yindawo ephindwe kali-7 kunomyinge owenzeka phakathi ku-Agasti. Kuphela yiminyaka ka-2012 kunye no-2021 ababhalise ngaphezulu komnyhadala omnye onyibilikileyo we-800.000 yeekhilomitha.
Uluntu lwenzululwazi lufunda nzulu ukuze lubone iziphumo ezinokubakho. Ngokwenzululwazi yoluntu, oku akuyena uphawu oluhle lweqhwa. Amanzi kumkhenkce enza ukuba umaleko unyibilika lula. Ayisiyi kuba shushu kuphela kwaye naxa iqondo lobushushu, kodwa amanzi athabatha ukukhanya kwelanga kube mnyama. Ukukuqonda oku kufuneka sazi umxholo wealbedo. IAlbedo sisixa semitha yelanga ebonakaliswa lilanga kwimiphezulu. Ukukhanya kombala wobuso kukuba, kokukhona imitha yelanga iya kubonakala. Kule meko, umkhenkce umhlophe mpela ngoko ke unesalathiso esiphezulu sealbedo. Njengoko inamanzi ngaphezulu kwaye imnyama kuneqhwa, ifunxa ukukhanya kwelanga okungaphezulu, nako okunyusa ukunyibilika.
Imvula iyonke kwiphepha lomkhenkce yayiziitoni ezingama-7 ezigidi. Ezinye izazinzulu ezisebenza kule ndawo ngokwabelana ngemifanekiso malunga nemeko yokunyibilika kwiqhwa laseGreenland kwaye kuyakhathaza.
Utshintsho olungalungiseki
Ingxelo yakutshanje ye-IPCC (iPhaneli yeeNgcali zeZizwe eziManyeneyo kuTshintsho lweMozulu) ilumkise ngotshintsho lwemozulu kunye nenkqubo yemozulu, esele iqale kwaye engenakuphinda ibuye kumakhulu okanye kumawaka eminyaka. Omnye wabo yi-Greenland enyibilikayo. Njengoko kumiselwe yiarhente, ukuqhubeka kweelahleko zomkhenkce kwinkulungwane yama-9 kuqinisekile kwaye, njengoko ezinye izifundo ziqinisekisile, zikhawuleza kunokuba bekulindelwe.
Ngokwenzululwazi yemozulu, i-trigger iyinto ekhutshiweyo ebangelwa yimisebenzi yabantu, kunye nokwehliswa okupheleleyo nokubonakalayo kokukhutshwa kweyona mfuno iphambili, ukuze imeko yemozulu izinzile kwaye azikho ezinye iimeko ezinzima.
E-Greenland, i-60% yokunyuka kwenqanaba lolwandle kungenxa yokunyibilika komkhenkce. Ukuba imeko yokulahleka komkhenkce iyaqhubeka kwinqanaba langoku, Ngama-2100, 400 ezigidi zabantu baya kuba semngciphekweni wezikhukula zonxweme minyaka le.
Njengoko ubona, utshintsho lwemozulu sele lusenza umonakalo omkhulu kwiplanethi yonke. Esi sisiqalo nje njengoko kuya kuba nzima kakhulu ukuguqula utshintsho. Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga nemvula eGreenland.
