Kusukela ekuguqulweni kwezimboni nokutholakala kokusetshenziswa kwamandla kwe izinto zokubasa, umhlaba usuqale ukukhipha uchungechunge lwamagesi abamba ukushisa abangela ukuguquka kwesimo sezulu emhlabeni jikelele. La mafutha ezimbiwa phansi akhiwa uwoyela, igesi yemvelo namalahle. Ziyizinsizakusebenza eziphelile futhi amandla wokuvuselelwa awekho esikalini somuntu. Ngakho-ke, ukwesaba okukhona ngokungazinzi kwamanani kawoyela kudala ingcindezi engapheli kohulumeni abafuna njalo ukuxhashazwa kwezinqolobane zikawoyela kwezinye izindawo ezifana ne-Arctic.
Kule ndatshana sizokwenza ukuhlaziywa okujulile ngokubaluleka kokuxhashazwa kwezindawo zokugcina uwoyela nemiphumela yako emibi emvelweni.
Amanani kawoyela
Ngenxa yobunzima obukhulayo bokukhipha uwoyela ezinqolobaneni, intengo yayo iyanda. Uma kukhulunywa ngokukhipha izinqolobane zikawoyela e-Arctic, kuvela indida yokufuna ukwazi. Ngokuqondile, izindawo ezigcina uwoyela e-Arctic zingasetshenziswa lapho kunoncibilikile owanele ukuze zikuvumele. Noma kunjalo, ukuxhashazwa kwalo kawoyela kuzobhebhethekisa nemiphumela yokufudumala kwembulunga yonke lokho kubangele ukuncibilika okuvumela ukuthi lezi zinqolobane zisetshenziswe.
Njengoba ukwazi ukubona, kuyindida ngandlela thile. Ukufudumala kwembulunga yonke kubangelwa ikakhulu yilesi sikhisi somoya obamba ukushisa emkhathini. Lokhu kusho ukuthi ukushisa okugcinwe kukhulu futhi kubangela ukwanda kwezinga lokushisa. Ngaphezu kwalokho, okuwukuphela kwenkinga ngalawa magesi atholakala ekushisweni kukawoyela akuyona nje into esemkhathini kuphela kodwa futhi nempilo.
Ngakolunye uhlangothi, sinezibhelu eMpumalanga Ephakathi zidala ukungazinzi okuphezulu kwezepolitiki. Yaqala kanjalo-ke inkinga yaseLibya lapho intengo kawoyela yenyuka ngo-15% yafinyelela ku- $ 120. Vele, konke lokhu kudale ukuzamazama komhlaba okuningi okungabizwa ngokuthi lokhu kuzamazama komhlaba, okungukungazinzi kwamanani ngokunyuka kwamanani amaningi ezifisweni zaseNtshona. Kulokhu kukhuphuka kwentengo, izinqolobane zikawoyela ezinkulu kunazo zonke emhlabeni zenziwa lapho singazithola khona.
Lesi yisisekelo esenza i-Arctic ingaba iphuzu eliyisihluthulelo elilandelayo ekusetshenzisweni kwezinqolobane zikawoyela. Ngokusho kochwepheshe, i-Arctic mhlawumbe iyona kuphela indawo emhlabeni wonke lapho kunezinqolobane zikawoyela ezingasetshenziswanga.
Izinqolobane zikawoyela e-Arctic
Ngoba i-Arctic iseseyintombi nto, kukhona ukugxila okukhulu kuyo. Kulinganiselwa ukuthi kunengcebo enkulu ye imithombo yemvelo nokuthi iMiddle East iyibhekile. IGreenland inguhulumeni ozimele oyingxenye yeDenmark. Ingelinye lamazwe amakhulu anentshisekelo ekusetshenzisweni kwezindawo zokugcina uwoyela. Noma kunjalo, ICanada, i-US, iRussia neNorway ngeke zisale emuva empini yalezi zinsizakusebenza.
Ochwepheshe abebehlola uwoyela e-Arctic amashumi amathathu eminyaka bathole imiphongolo kawoyela engaphezu kwezigidi ezingama-3. Ngokuya ngocwaningo maqondana nalokhu, kulinganiselwa ukuthi kuseneminye imigqomo eyizigidi eziyizinkulungwane eziyi-114.000 ngaphezulu engakatholakali. Ngakolunye uhlangothi, sithola nokuthi ama-cubic metres angama-trillion angama-56 egesi yemvelo angasetshenziswa. Yonke le mithombo yamandla amnandi isemilonyeni yamazwe amaningi alambele amandla namandla.
Umbuzo ucacile, yini elandelayo elandelayo? Bazosebenzisa izindawo ezigcinwe e-Arctic ezonakalisa imvelo futhi baholele ekuqedeni kwalezi zinsizakusebenza. Uma uwoyela usuphelile, kuzokwenzekani? Sizoba sezweni elinezinkinga ezinkulu zokungcola nokufudumala kwembulunga yonke, elinokuhlukahluka okuncane kanye nezifo eziningi. Ukuphela kwento abacabanga ngayo ukuceba ngempilo abanayo futhi abacabangi ngezizukulwane ezizayo.
Imiphumela yezemvelo
Uma izilinganiso zalokho okwenziwe ezifundweni ziyiqiniso, sithola ukuthi lezi zinqolobane zikawoyela bezizolingana nengxenye yesihlanu yawo wonke uwoyela ongakatholakali emhlabeni. Lokhu kubiza kuphela indida yase-Arctic: izinsiza ebezingafinyeleleki ngeqhwa zenziwe zaba lula ukuguquka kwesimo sezulu okulethwe wona kanye uwoyela abazama ukuwukhipha. Ukuncibilika kwe-Arctic ngeke nje kukhulise imiphumela yokuguquka kwesimo sezulu ngokushintsha i-albedo yoMhlaba, Esikhundleni salokho, ukukhishwa kwalezi zindawo zikawoyela kuzokwenza isimo sibe sibi kakhulu.
Akufanele sikhohlwe ukuthi i-Arctic ingenye yengcebo umhlaba onayo ngokubaluleka kwemvelo. Indawo ehlanzeke ngokuphelele lapho kungekho mthombo owake waxhashazwa khona futhi ukuhlukahluka kwemvelo kugcinwe kuvikelwe yiqhwa. Iqhwa likhona e-Arctic ingxenye kuphela yonyaka. Ngaphambi kokuthi kube unyaka wonke. Ngaphezu kwalokho, ngeke nje kubangele ukulimala kwemvelo, kepha futhi kungaphula ukuzinza kwayo.
Le ndawo ishisa ngokuphindwe kathathu kunawo wonke umhlaba. Lokhu kuzodala ukuthi, ngokunokwenzeka, imvelo yendawo yonke le ndawo ithole amaphuzu okungenakuphindiswa. Ukusheshiswa kokulahleka kweqhwa kwandisiwe ngakho-ke, izinguquko eziningi ezingazelelwe zizovela emvelweni.
Amazinga eqhwa aphansi
Amazinga aphansi kunawo wonke emlandweni aqoshwe e-Arctic ice sheet ngenxa yokunyuka kwamazinga okushisa. Njalo ehlobo ungqimba luyancibilika ngokuya lubanda futhi ebusika. Kodwa-ke, leli zinga elisheshayo lokuncibilika libangele ukwehla kwezinga lokubandayo elihumusha ekulahlekelweni yiqhwa ngokuphelele.
Lapho sibhekene nokucatshangelwa kwemvelo ukuxhaphaza lezi zinsizakusebenza siyayijoyina ngezizathu zenhlalo nezepolitiki. Njengamanje, i-Arctic inabantu abangaba yizigidi ezine. U-4% walaba bantu yizizwe zendabuko ezithi Banelungelo lalemithombo yemvelo yomhlaba lapho behlala khona futhi ingeyabo ngokusemthethweni.
Ngakho-ke, sizobona ukuthi le mpikiswano yokusetshenziswa kwezinqolobane zikawoyela ixazululwa kanjani. Ngiyethemba bayabuya ezingqondweni zabo basebenze kakhulu ngamandla avuselelekayo.
