Amatye entaba-mlilo ukubamba ngakumbi i-CO2

tyala amatye entaba-mlilo ukuze ubambe ngakumbi i-co2

Amafama kwihlabathi jikelele anethuba lokuba negalelo kwiinzame zeplanethi yokususa ikhabhoni ngokubandakanya amatye entaba-mlilo atyumkileyo kumasimi abo, ngokophononongo. Uphononongo lukwaqaqambisa ukuba iitropiki ezifudumeleyo nezifumileyo zibonelela ngezona meko zilungileyo ukuphumeza esi sicwangciso-qhinga songenelelo lwemozulu. Kwaye zinokusetyenziswa amatye entaba-mlilo ukubamba ngakumbi i-CO2.

Kweli nqaku siza kukuxelela indlela amatye e-volcanic anokusetyenziswa ngayo ukubamba i-CO2 engaphezulu, zeziphi izifundo ezikhoyo kulo mbandela kunye nokuba yintoni enokuba nayo ukulwa nokutshintsha kwemozulu.

Ushicilelo lwe-Earth's Future lubonisa olunye lovavanyo lokuqala lwehlabathi lokuthinjwa kwekharbon dayokhsayidi ngokucwangciswa kokubekwa kwamatye e-basalt kumasimi ezolimo kwihlabathi jikelele.

Igama lobuchwephesha kolu hlobo longenelelo lwemozulu “yimozulu eyongeziweyo yamatye.” Ithatha ithuba lenkqubo yendalo yokhukuliseko lwamatye, ethi ngokwendalo igcine i-carbon dioxide kwiiminerali ze-carbonate. Ingcamango ilula: ukukhawulezisa inkqubo yokhukuliseko ngendlela ekwaneempembelelo ezintle ebantwini. Xa iphunyezwa kunye neenzame zokunciphisa ukukhutshwa kwezinto ezikhutshwayo, inganceda ukuthomalalisa inkqubela ekhawulezileyo yokutshintsha kwemozulu.

Ababhali bophononongo bacebisa ukuba ukubandakanya amatye kwizityalo kunokuba lukhetho olukhuselekileyo lokunciphisa ukukhutshwa kwekhabhoni xa kuthelekiswa nezinye iinkqubo. S. Hun Baek, isazi semozulu kwiYunivesithi yaseYale kunye nomphandi oyintloko wophando, ichaze ukuba ukwanda kokhukuliseko lwamatye kuthwala imingcipheko embalwa xa kuthelekiswa nezinye iindlela zokungenelela kwimozulu. Ngaphaya koko, le ndlela inika uncedo olongezelelweyo, njengokuvuselela imihlaba esele iphelile kunye nokunciphisa imiphumo ye-asidi yolwandle, enokuthi inyuse umtsalane wayo ngokwembono yentlalo.

amatye eentaba-mlilo

Ngolu cwaningo olutsha, amandla okusebenzisa i-basalt echotshoziweyo, uhlobo lwelitye elenza ngexesha lokupholisa i-lava kunye nokutshabalalisa ngokukhawuleza, kwiinkalo zezolimo emhlabeni jikelele zihlolwe. Ngaphandle koko, Uphononongo luchonga imimandla apho ukuqhekeka kwamatye kunokuthi kwenzeke kakhulu ngokusebenzayo.

Ngokutsho kophando umbhali-mbhali uNowa Planavsky, i-geochemist kwiYunivesithi yaseYale, kukho amandla amakhulu kule ndawo. Nangona kusekho okuninzi okufunyaniswayo ngokwembono yenzululwazi, kukho izizathu zokuba nethemba kwaye sijolise ingqalelo yethu ekuphononongeni okunokwenzeka ngokweembono zentengiso nezemali.

Ukusetyenziswa kwe-basalt echotshoziweyo njengesilungiso somhlaba kwimisebenzi yezolimo kubonakalise ukuba luncedo kwizityalo. Ukuvavanya ukusebenza kwemozulu eyongeziweyo yamatye ekubanjeni ikharbon diokside kunye nokumisela ubuntununtunu bayo kwimozulu, Abaphandi basebenzise imodeli entsha ye-biogeochemical. Ukongeza, bachonge imimandla apho le ndlela inokuvelisa iziphumo ezingcono.

Ngokusebenzisa imodeli entsha, abaphandi bakwazi phinda ukuphunyezwa kwale nkqubo kwiindawo ezili-1.000 2006 zezolimo kwihlabathi jikelele, phakathi ko-2080 no-XNUMX., kuthathelwa ingqalelo iimeko ezimbini ezahlukeneyo zokukhupha izinto ezikhutshwayo. Iziphumo zabo zibonise ukuba kwiminyaka engama-75 yophando, ezi ndawo zezolimo ziyakufunxa i-64 gigatonnes ye-carbon dioxide. Ukuba sikhupha le datha ukugubungela onke amasimi ezolimo, emele umda opheleleyo wesakhono sesi sicwangciso kwihlabathi liphela, kuqikelelwa ukuba iigigatonnes ezingama-217 zekhabhoni zinokubanjwa ngokufanelekileyo kwangelo xesha linye.

Izibonelelo zokusebenzisa amatye entaba-mlilo ukubamba i-CO2 eninzi

Ukukhutshwa kweCO2

Ngokutsho kukaBaek, Ingxelo ye-IPCC yakutshanje igxininisa ukungxamiseka kokuphelisa phakathi kwe-100 kunye ne-1.000 gigatonnes ye-carbon ngo-2100, kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo okubalulekileyo, ukucothisa ukunyuka kwamaqondo obushushu behlabathi ukuya kutsho kwiqondo elinye elinesiqingatha ngokukaCelsius.

Ngokuhlalutya ukwanda komhlaba wezolimo kwihlabathi jikelele, siye safumanisa ukuba uqikelelo lokususwa kwekhabhoni luhambelana ngokusondeleyo neemfuneko ezifunekayo ukuze sibe nethuba lokufikelela iinjongo zemozulu ezinqwenelekayo.

Uphononongo lugxininisa ukuba ukusetyenziswa kwamatye kwindawo yezolimo kuya kuba neempembelelo ezikhawulezayo kwimimandla yetropikhi xa kuthelekiswa nobude obuphezulu ngenxa yenkqubo yokukhukuliseka okukhawulezileyo kwiindawo ezishushu nezifumileyo. Kuba ukwenza izigqibo ezisebenzisekayo ngokwezoqoqosho neziluncedo kokusingqongileyo malunga nokususwa kwekhabhoni, amafama kunye neenkampani kufuneka zibeke phambili ukuphunyezwa kwe-basalt kwiindawo ezitshisayo.

Inkqubo yokubamba ngokwemvelo kunye nokugcina i-CO2

Kubushushu obufudumeleyo, imodeli ibonise enye into ekhuthazayo: Uphuculo lokhukuliseko lwamatye lubonakala lusebenza ngokulinganayo, ukuba akunjalo nangaphezulu. Ngokwahlukileyo koko, ezinye iindlela zokubamba ikharbhon, ezifana nezo zixhomekeke kugcino lwekhabhoni ephilayo emhlabeni, amava anciphile ukusebenza njengoko amaqondo obushushu enyuka.

U-Baek uvakalise ukuba ukomelela kokhukuliseko lwamatye ngexesha lokutshintsha kwemozulu kuyamangalisa. Iziphumo zibonisa ukuba ayichatshazelwa kakhulu kukutshintsha kwemozulu kwaye ihlala isebenza kakhulu naphantsi kwemodareyitha ukuya kwiimeko ezinzima zokufudumala kwehlabathi. Ezi ziphumo zibethelela ukuzithemba ekusebenzeni kwayo njengesicwangciso sexesha elide.

Ngokutsho kukaPlanavsky, Ngoku amafama afaka izixa ezikhulu zelitye likalika, ilitye le-calcium carbonate elinokuthi lisebenze njengomthombo wekhabhoni okanye i-sink, emasimini akho ukubonelela ngezondlo kunye nokulawula ubumuncu bomhlaba. Ukutshintshela kancinci kancinci kuhlobo olwahlukileyo lwamatye kungaququzelela ukuphunyezwa okugudileyo kwemozulu yamatye ephuculweyo kwisikali esikhulu.

Ukuphunyezwa kwemozulu ephuculweyo yamatye iye yavavanywa ngempumelelo kwiifama kwihlabathi liphela, nangona kukwinqanaba elilinganiselweyo. Ukukhangela kwikamva, Ugxininiso ngoku lusekuphumezeni “uphumezo oluyinyani,” njengoko watshoyo uPlanavsky.

Njengoko ubona, ukusetyenziswa kwenzululwazi kunokuncedisa ngakumbi ukulwa nokutshintsha kwemozulu ngeendlela ezingalindelekanga. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nezifundo ezitsha malunga nokusebenzisa amatye e-volcanic ukubamba i-CO2 eninzi kwaye ngoko ukwazi ukulwa nokutshintsha kwemozulu.
