Ngokusho kocwaningo olusha olwenziwe yi-Imperial College London, ukuguqula ukuphakama kwezindiza kungaphansi kwamaphesenti amabili kunganciphisa ukuguquguquka kwesimo sezulu okuhambisana nokungahambisani namaphesenti angama-2.
Ukuthinta kungaba kubi kakhulu kwesimo sezulu njengokukhishwa kwe-CO2
Lapho imishini yokushisa eqeda ukushisa evela ezindizeni indiza ihlangana nomoya obandayo, ophansi kakhulu emoyeni, idala imisinga emhlophe esibhakabhakeni, eyaziwa ngokuthi yi- "contrails" noma contrails. Lokhu kwephula kungaba kubi kwesimo sezulu njengokukhishwa kwabo kwe-CO2.
Imikhuba eminingi ihlala kuphela imizuzu embalwa, kepha eminye ixubana nabanye futhi ihlale isikhathi esingafika emahoreni ayishumi nesishiyagalombili. Ucwaningo lwangaphambilini lukhombisa ukuthi izingqinamba namafu okubenza babe ukushisa isimo sezulu kanye nokukhuphuka kwe-CO2 ekukhuphukeni kwendiza.
Umehluko omkhulu: Ngenkathi i-CO2 ithonye umkhathi ngamakhulu eminyaka, izingqinamba zihlala isikhathi esifushane futhi zingancishiswa ngokushesha.
Ukulimala okubangelwa yimikhawulo kungancishiswa kuze kufike ku-90%
Ucwaningo lwe-Imperial College London lukhombisile ukuthi izinguquko ekuphakameni kwamamitha ayi-2.000 90 kuphela zinganciphisa ukusebenza kwawo. Ngokuhlanganiswa nezinjini zezindiza ezihlanzayo, ukulimala kwesimo sezulu okubangelwa yizingqinamba kungancishiswa kuze kufike ku-XNUMX%, kusho abaphenyi.
Umbhali oholayo uDkt. UMarc Stettler ovela eMnyangweni Wombuso Wezobunjiniyela Kwezomnotho kanye Nezemvelo uthe: "Le ndlela entsha ingasheshe yehlise umthelela wesimo sezulu embonini yezindiza."
Abaphenyi basebenzise ukulingisa kwamakhompiyutha ukubikezela ukuthi ukushintsha ukuphakama kwezindiza kuzonciphisa inani lokuphambana nokuthi bangahlala isikhathi esingakanani. Ukweqa kwakha izingqimba ezincanyana zomkhathi ezinomswakama ophakeme kakhulu futhi eziqhubekayo. Ngakho-ke, izindiza zingazigwema lezi zifunda. UDkt. UStettler uthe, "Ingxenyana encane impela yezindiza ibhekele imiphumela eminingi yesimo sezulu esincintisayo, okusho ukuthi singabanaka."
"Ukugxila ezindizeni ezimbalwa ezidala ukwephula umthetho okulimaza kakhulu, nokwenza ushintsho oluncane kuphela ekuphakameni, kunganciphisa kakhulu umthelela wokwephula ukufudumala kwembulunga yonke," kusho umbhali oholayo uRoger Teoh woMnyango Wezobunjiniyela Bezemvelo Nezemvelo. Ukwakheka komngcele okwehlisiwe kunganciphisa i-CO2 ekhishwe ngophethiloli owengeziwe.
Dr. UStettler uthe: “Siyazi ukuthi noma iyiphi i-CO2 eyengeziwe ekhishwe emkhathini izoba nomthelela esimweni sezulu esiba khona kumakhulu eminyaka esizayo. Kungakho sibalile ukuthi uma sihlose kuphela izindiza ezingakhiphi noma iyiphi i-CO2 eyengeziwe, usengafinyelela ukwehliswa okungama-20% ku-contrail drive. "
