Iziphumo zendalo eluhlaza kunye notshintsho lwemozulu luneziphumo kunye nezizathu ezingaziwayo kuluntu lwenzululwazi. Asazi kakuhle ukuba inokuchaphazela njani izinto ezithile ezenziwa ngabantu kunye neempembelelo kwitsheyini lokutya, njl. Kule meko siyayibona indlela enyibilikayo eyenzeka ngenxa yokufudumala kwehlabathi kubangela ukwanda kobumnyama baseArctic kwaye oku kuyenza mandundu ifuthe lesiphumo sendawo yokugcina greenhouse.
Ibangelwa yintoni le nto?
Ubuncwane kwi-arctic
Inqanaba lomkhenkce kwiArctic lelona lirekhodi lisezantsi ukusukela ngo-1978 kunye nokuziphatha kwemozulu kwiindawo ezohlukeneyo kuya kusiba yinto engalindelekanga. ngenxa yongcoliseko. Abaphandi kunye noososayensi bazama ukuqonda indlela ukunyibilika kunye nokwanda kwesembozo selifu kuzenze zanzima ngakumbi iziphumo zempembelelo kwigreenhouse kwipali.
I-hypothesis yesayensi isekwe kungcoliseko njengoyena nobangela wezi nguqu. Okokuqala, ukufudumala kwehlabathi kunye nokunyuka kwamaqondo obushushu kwiplanethi kwenza i-Arctic ice inyibilike, ngenxa yoko ukukhanya kwelanga akusabonakalisi kubuyela esithubeni kwiindawo apho kungekho mkhenkce. Emva kokuba ukunyibilika kungabonakali nje kuphela, kodwa kukwafunxa ukukhanya, ebangela ukuba ukufuma okukhutshiweyo kuphakame kwenziwe amafu. Ingxaki ibonakala xa la mafu esenza njengengubo, ekugcina ufudumele.
Ukuphanda ngefuthe lale meko kwimozulu, kuphuhliswa imishini yomoya apho inqwelomoya yenza i-flybys ezininzi ezithatha idatha ethelekiswa nemilinganiselo ethile evela kwiisathelayithi. Oososayensi banesizathu sokucinga ukuba ukunyibilika kunye nelahleko yomkhenkce kubangela ukwanda kokwakhiwa kwelifu. Kungenxa yoko le nto befuna ukumisela iimpembelelo abanokuthi bazikhuphe.
