Umbono usenokubonakala ngathi uphambene, kwaye nangona bebabiza bengazi nto, baqinisekile ukuba isayensi kunye netekhnoloji ingenza ukupholisa kweplanethi kwenzeke. Ayiloqela lasekuhlaleni labantu, kwaye abaphambani abaqokelele utyikityo. Sithetha ngabathile ababonayo, isayensi entsha ebizwa ngokuba yi-geoengineering. Eli qela leenjineli lithumela oku kulandelayo. Isenzo somntu sifudumeza iplanethi, akunjalo? Ewe, masisebenzise ithuba lomntu ukuba apholise.
Kuzo zonke ezi ngcinga, bekhatshwa ngabagxeki Iziphumo kunye neziphumo abanokuthi babe nazo. Bahlukile kuloo nto Yinto enye ukutshintsha imozulu ngokungazi andabikho zingqondweni kwaye enye kukuyiguqula ngabom. Abakhuseli, kwelinye icala, bayayibona ngokucacileyo indlela ungenelelo olukhawulezileyo olufunekayo. Izifundo ezininzi zibonisa ukuba xa isenzo somntu singapheli, amaqondo obushushu aya kunyuka aphakame kakhulu. Kwelinye icala, kukho izifundo ezibonisa ukuba nokuba bekuyeke ngokupheleleyo ukusebenza kwabantu, ukufudumala, nangona kunzima, kuya kuqhubeka. Ukufumana isisombululo kwangoko, eli nyathelo liyazalwa.
Ngobunjineli
Imalunga nesayensi yamva nje enoxanduva lokwenza ezi ndlela kunye nokucebisa ngezisombululo. Njengoko sele siphawulile, kukho udumo olujikeleza apho olungamkelwanga kakuhle. Ukufumana umbono, khawufane ucinge nje iinguqu ezimbalwa. Ukuba indawo ibethwa yimbalela, imilambo incinci, okanye imilambo engenanto okanye eyomileyo ... Yintoni ephosakeleyo ngokunqwenela ukuba imvula? Kukho iilwandle ezome ngokupheleleyo. Iziphumo zezi zinto zoyikekayo. Ngaba lolona nyango lubi kwesi sifo? Kwaye mpikiswano iyavula.
KwiYunivesithi yaseScotland yase-Edinburgh, injineli ye-geo uStephen Salter ukhokela enye yeeprojekthi ezinamabhongo izinto zobunjineli. Umbono ulula kakhulu. Ukuqaliswa kwegranules yomphunga wamanzi kunye neetyuwa eziphezulu kwi-troposphere. Emva kwexesha, iinqanawa ezinkulu ze-transatlantic zaziza kuthwala iitshimini ezinkulu ebhodini ezaziza kufafaza la mathontsi amanzi netyuwa. Nje ukuba bafike kwi-troposphere, la mathontsi aya kuba yinxalenye yamafu kwaye aya kwandisa iqondo lokuphinda ubuye yeegesi zomoya. Oko kungadala ukuba imitha yelanga ifikelele eMhlabeni. Ekugqibeleni, la mathontsi aya kusebenza njenge-condensation nuclei yegesi zamafu. ukuthanda imvula.
Ngubani owayiqambayo?
UPaul Crutzen, ngo-1995 uMphumeleleyo weNobel kwiKhemistry, kuphando lwakhe malunga nefuthe le-ozone emoyeni. Kwelinye icala, ungomnye woososayensi abathe banegalelo elikhulu ekukhuseleni indalo. Yena ngokwakhe ucacisile indlela iichlorofluorocarbon (CFC) zeemolekyuli ezinefuthe ngayo ekunciphiseni kocingo lweozone.
Paul Crutzen, phantsi kwengcinga yokuba nayo umntu uyakwazi ukupholisa iplanethi, waphawula ukupholisa ngequbuliso okwenzeka emva kogqabhuko-dubulo lwentaba-mlilo. Iindlela ezisebenza ngayo zijongana nenaliti enkulu yesalfure emoyeni ukuze ibangele iziphumo zeentaba-mlilo.
Isikali. Iprojekthi yobunjineli entsha ye-2018 elandelayo
Ngoku ujonge ngaku eyunivesithi yaseHarvard. Enye yeeprojekthi ezizayo abafuna ukuzazisa ngefayile ye- Kunyaka olandelayo kwintlango yaseTucson, eArizona, ngokoqobo cinga uluvo lwe pholisa iplanethi.
Iprojekthi yile ilandelayo. Ezinye iibhaluni zomoya ezishushu zilayishwe ngumkhenkce wamanzi wecalcium carbonate kunye nesalfure dioxide, ziya kunyuka ziye kwiikhilomitha ezingama-20 ukuphakama kwaye ziya kuthi zivelise iierosol ngezi zinto. Nje ukuba bakhululwe, banokubangela ukusasazeka kwemitha yelanga, esebenza njengoluhlobo lweparasol ngokumisa imitha yelanga, wakhonza ukupholisa iplanethi. I-Scopex, luvavanyo lokuqala lokwenyani lwembewu yelifu. Ngale ndlela, ijolise ekubuyiseleni ukufudumala kwehlabathi ngokupholisa.
Kukho ukuvumelana malunga nokufudumala kwehlabathi. Abaxhasi be-geoengineering bazikhusela ngokunika into yokuba mhlawumbi abaninzi ngoku abayiqondi, kodwa ikamva alinakuphepheka. Kwaye ekugqibeleni wonke umntu uyakumanga bathi.
Ingxabano iyanikezelwa. Ngaba ihambe kakhulu? Ngaba ikhona indlela yokuthethelela isiphelo? Ngaba ayinabungozi okanye iya kuba neziphumo?
