izinto zobunjineli

Siyazi ukuba enye yeengxaki ezinkulu ezijongene nabantu kule nkulungwane kukutshintsha kwemozulu. Ukwanda kwamaqondo obushushu ehlabathi kubangela utshintsho kwimozulu kwihlabathi jikelele. Iziphumo zesimo zinokuba yintlekele kwaye kufuneka ziphetshwe ngazo zonke iindleko. Kule nto, idale i i-geoengineering. Abantu abaninzi abazi ukuba yintoni i-geoengineering okanye izama ukwenza ntoni.

Ngoko ke, kweli nqaku siza kukuxelela ukuba yintoni i-geoengineering, zithini iimpawu zayo, iinjongo kunye nokunye okuninzi.

Yintoni i-geoengineering

iikhemikhali

I-Geoengineering ibhekisa kwi isethi yobuchwepheshe eyenzelwe ungenelelo lwemozulu kwilinge "lokulungisa" utshintsho lwemozulu. Olu qeqesho lunqwenela ukuba yitekhnoloji kwinqanaba leplanethi.

Inzululwazi ngoku ijongene nemingeni emibini: ukufunxa ikharbon diokside emoyeni ukuze iatmosfera ibambe ubushushu obuncinane, kwaye ibonakalisa ukukhanya kwelanga okuthe kratya ukuze uMhlaba ufunxe ubushushu obuncinane.

Olu qeqesho luphuhlayo sele lukhokelele abanye abaphandi ukuba baphande, ngokusebenzisa ukulinganisa kwekhompyutha okanye iimvavanyo zebhubhoratri ezincinci, iminikelo eya kuziswa nguphuhliso lwe-geoengineering, kunye neengozi ezinokuzisa.

Kulo msebenzi amasimi olwazi lobunjineli, ijografi kunye nesayensi yekhompyuter zidityanisiwe, ngoko Yinzululwazi esoloko ixoxwa malunga nobungakanani bokungenelela kwayo.

Iimpawu eziphambili

yintoni i-geoengineering

Olunye lolona bhejo luyingozi kakhulu ebusweni bokutshintsha kwemozulu yi-geoengineering, ingqikelelo equka izindululo ezahlukeneyo zobugcisa bokulawula imozulu yehlabathi ukulungisa ezinye zeempawu zesiphithiphithi semozulu. Inomngcipheko wokusingqongileyo, wentlalo kunye nezopolitiko, kodwa owona mngcipheko mkhulu wangoko kukuba iba sisingxengxezo sokungasebenzi kwemozulu: isetyenziswa njengesizathu sokuqhubekeka kunye nokwanda kokukhutshwa kwegesi yegreenhouse (GHG), kwaye ithembisa ukuba kwixesha elizayo kuya kubakho ubugcisa bokubuphelisa okanye ukunciphisa ubushushu.

Sisithembiso esingenanto, kuba uninzi lwale mbono luyithiyori kuphela, kwaye ezimbalwa eziphuhliswe kancinci ekusebenzeni ziyiprototypes, okanye azisebenzi ngenxa yezizathu ezahlukeneyo. Akukho meko ziya kuphuhliswa kwinqanaba lezorhwebo okanye kwinqanaba elikhulu lehlabathi ukuba libe nempembelelo ebalulekileyo ekufudumeni.

Nangona kunjalo, izindululo ze-geoengineering zinomtsalane kakhulu kumashishini angcolisekileyo anegalelo ekukhutshweni kwegesi ephezulu yobushushu, njengamandla efosili, imigodi, ezothutho, iimoto, ishishini ngezolimo, njl., kunye namazwe abambeleyo amaqumrhu amakhulu alawula la mashishini. Kubonakala ngathi "ukulungiswa" kobuchwepheshe obunokuthi buvumele imisebenzi yokungcolisa ukuba iqhubeke ngaphandle kokujongana neenguqu ezisisiseko ezifunekayo kwimveliso kunye neepatheni zokusetyenziswa. Ngelo xesha, ivula izibonelelo ezintsha kunye namathuba orhwebo, uphuhliso kunye nokukhutshwa.

Ngokusisiseko, bayindlela yokudala imakethi enkulu yokubanjelwa yehlabathi: izizathu zokutshintsha kwemozulu ziyaqhubeka, ngoko ke ingxaki yemozulu iyaqhubeka ikhula, ngoko ukuthengisa iteknoloji ukulawula iimpawu, ukuba ziyasebenza, zivula ihlabathi, xa sele liqalile, alinakubanjwa, lihlawulwe kakhulu ngamazwe. Ukutyhalela phambili kwengcamango elahlekisayo “ye-zero” yokuphelisa ukukhutshwa kwezinto ezikhutshwayo endaweni yokuyinciphisa ikwaliqonga le-geoengineering “njengolungiso” lobuchwephesha.

izindululo Geoengineering

tshintsha imozulu

Ubuchule beGeoengineering ngokubanzi buwela kwiindidi ezintathu ezibanzi: ezo zenzelwe ukususwa kwecarbon dioxide; abo bazama ukubonakalisa inxalenye yemitha yelanga kwindawo yokunciphisa amaqondo okushisa kunye nokuguqulwa kwemozulu yendawo, ukubangela okanye ukuphepha imvula, isichotho, njl.

Ngoku kukho malunga ne-25-30 yeziphakamiso ze-geoengineering kwezi ndidi zintathu., ecebisa ukusebenzisa umhlaba, elwandle kunye/okanye ne-atmospheric ecosystem. Nangona kunjalo, akukho namnye kubo ozama ukulungisa okanye ukuguqula oonobangela bokutshintsha kwemozulu, kodwa kunoko ukulawula ezinye zeempawu zayo.

Phakathi kweetekhnoloji ezicetywayo kukho ezo cebisa ukuba utofwe ii-sulfates okanye ezinye iikhemikhali kwi-stratosphere ukuthintela ukukhanya kwelanga, ngaloo ndlela ithomalalisa imitha yemitha efikelela eMhlabeni; enze mhlophe okanye akhazimlise amafu olwandle ukuze abuyisele ukukhanya kwelanga emajukujukwini; ukuphuhlisa amaziko okubamba ikharbon diokside ukusuka kwi-atmosfera kwaye iyingcwabe kwimithombo yeoli okanye ezinye iimo zejoloji emhlabeni naselwandle; ukuchumisa iilwandle nge-iron okanye iurea ukukhuthaza ukukhula ngokukhawuleza kweplankton ngethemba lokuba ziya kufunxa ngakumbi ikharbon diokside zize ziyiguqule ukuze izike ezantsi elwandle; ukutshintsha i-chemistry yolwandle ngamatye atyunyuziweyo ukuze enze i-alkaline ngakumbi; kunye nokutyala iziqwenga ezinkulu zemithi okanye izityalo eziguqulwe ngokwemfuza ekuthiwe zifunxa ngakumbi ikhabhoni okanye zibonakalise ngakumbi ukukhanya kwelanga.

Ngaba ngokwenene inokunceda ukulwa nokutshintsha kwemozulu?

Ukuza kuthi ga ngoku ezona ziphakamiso zixhaphakileyo zezo zibandakanya ukususwa kwekhabhoni kunye nokugcinwa kwayo. Ukubamba kunye nokugcinwa kwekhabhoni (CCS okanye iCCS), indlela yakudala yoshishino lweoyile esetyenziselwa ukufikelela koovimba be-hydrocarbon enzulu, ngokumangalisayo ikhupha ioyile eninzi, nto leyo ekhokelela ekukhutshweni kwegesi yegreenhouse.

Izindululo ezisekelwe kule teknoloji, ezifana ne-bioenergy kunye nokubanjwa kwekhabhoni kunye nokugcinwa (i-BECAC okanye i-BECCS), ibandakanya ukukhula kwezityalo ezinkulu zemithi okanye izityalo kwaye emva koko ukusika / ukutshisa ukuvelisa "i-bioenergy", edityaniswe ne-CCS ukubamba ukukhutshwa kwekhabhoni. ukusuka kwimveliso. Ngokufanayo, ukubamba umoya ngokuthe ngqo (i-DAC efinyeziweyo okanye i-DAC) isebenzisa, umzekelo, iiyunithi ezinkulu zefeni ukucoca umoya kunye nokwahlula i-CO2 kunye nezinyibilikisi zemichiza, emva koko iiCCCs zingcwaba ikhabhoni okanye ziphinde ziyisebenzise kwiimveliso ezahlukeneyo, ukwenzela ukuba kuthathe ixesha elide Kungekudala okanye kamva i-CO2 iya kubuyela emoyeni, ngoko akufanele kubizwe ngokuthi "ukugcinwa." Ishishini lefosili unomdla kakhulu kuzo zonke ezi teknoloji kwaye wenza isambuku sotyalo-mali kula manyathelo.

Kutshanje, abaxhasi be-geoengineering bazamile ukuziqhelanisa negama elithi "geoengineering," mhlawumbi ngokucebisa itekhnoloji yodwa okanye ngokuchaza ukuba itekhnoloji yokususa ikharbon diokside yahluke kakhulu kwitekhnoloji ye-solar geoengineering kangangokuba kufuneka ziqwalaselwe ngokwahlukeneyo. Ngelixa obu buchwepheshe bohluke ngenene omnye komnye, into abafana ngayo bonke kukuba bonke bacebisa ngokuphathwa kwemozulu ngobuchwepheshe obukhulu.

babize ngabanye ngabanye yindlela yokuphepha ukuqwalaselwa kwempembelelo yayo enkulu kwingingqi okanye yehlabathi, ukuphepha uhlalutyo oluyimfuneko lweziphumo ze-synergistic ezivela ekusetyenzisweni kwangaxeshanye kwezininzi zezi teknoloji, kwaye okona kubaluleke kakhulu, ukuphepha ukuguqulwa koluntu kunye noluntu ngokubanzi, kwasekuqaleni ukuqonda ukuba obu buchwephesha obunobungozi obuphezulu.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokuba yintoni i-geoengineering kunye neempawu zayo.

    Kuyathakazelisa kakhulu ukuba i-geoengineering ixoxwe kwaye imifanekiso yeendlela ezishiywe ziinqwelomoya zibonisiwe. Yintoni kwinqanaba lesitrato abanye abayibiza ngokuba yi "chemtrails" okanye "iindlela zeekhemikhali" ngeSpanish. Ekubeni zibonisiwe, kodwa zingathethi ngokuthe ngqo, ndifuna ukubuza umbuzo malunga nazo. Ngaba zikho ngokwenene? Ndithetha ukuthi, xa bezibona, kukho abo bathi ziyimveliso yomxube wegesi kumaqondo obushushu aphezulu kunye namasuntswana abangela ukuxinana kula mafu kwiimeko ezithile, ngelixa abanye bephikisana ngelithi ziimveliso zemichiza eziqaliswe ngokukodwa ukusuka kwiinqwelomoya ukuya kwinqwelomoya. guqula imozulu. Njengoko inqaku likhankanya, kukho iindlela zokubangela imvula okanye ukuphepha umonakalo kwisichotho, kodwa ... ngaba ezo zithintelo esizibonayo ziyafana? Ngaba ukho umthombo osemthethweni onokuwuqinisekisa?

    Njengamaxesha onke ukhanyisela UKUGQIBELA ngale miba yangoku, efana "nokutshintsha kwemozulu", esele isibonisa iziphumo zayo ezimbi (iinkanyamba, ikhephu, izikhukula, amaqondo obushushu aphantsi kakhulu kunye aphezulu ...) kunye nezizathu zalo monakalo Iplanethi baqhubeka nokuphakamisa iziphakamiso zexesha elide kunye noluntu lubandezeleka kwimiphumo yento ebizwa ngokuba "inkqubela phambili"... Ndiyabulisa
