Tsambali limagwiritsa ntchito makeke kuwonetsetsa kuti mumapeza zinthu zabwino kwambiri mukamasakatula.Kudina "Pezani" kumatanthauza kuti mukuvomereza mawuwa.
Asayansi akufufuza momwe angagwiritsire ntchito asibesito m’zinyalala za m’migodi kusunga mpweya wochuluka wa carbon dioxide mumpweya kuti uthandize kuthana ndi vuto la nyengo.
Asibesitosi ndi mchere wachilengedwe womwe kale unkagwiritsidwa ntchito kwambiri ngati kutchinjiriza kutentha komanso kuletsa moto m'nyumba.Zogwiritsidwa ntchitozi zimadziwika bwino chifukwa cha zinthu zoyambitsa khansa, koma zakhala zikugwiritsidwa ntchito pamabuleki ena agalimoto ndi matayala apadenga ndi padenga pamakampani a chlorine.Ngakhale kuti mayiko 67 tsopano akuletsa kugwiritsa ntchito zipangizo za fiber, United States si imodzi mwa izo.
Tsopano, ochita kafukufuku akuyang'ana kwambiri mitundu ina ya asibesito ya fibrous, yomwe ndi zowonongeka kuchokera ku migodi.Malinga ndi Eos, mtundu wapamwamba kwambiri womwe umapangitsa kuti asbestos ukhale wowopsa pakukoka mpweya umapangitsanso kukhala okonzeka kugwira tinthu ta carbon dioxide toyandama mumlengalenga kapena kusungunuka mumvula.Lipotilo limafotokoza kuti mtunda wautali wa ulusi umawapangitsa kukhala "okhazikika komanso osavuta kusintha" kukhala ma carbonates opanda vuto akasakanikirana ndi carbon dioxide.Izi zimachitika mwachilengedwe pamene asibesitosi akumana ndi mpweya wowonjezera kutentha.
Malinga ndi MIT Technology Review, zida zokhazikikazi zimatha kutsekereza mpweya wowonjezera kutentha kwazaka mamiliyoni ambiri ndipo zatsimikizira kuti ndi njira yabwino yotengera mpweya wambiri wa carbon dioxide kuchokera mumlengalenga.Asayansi akuyembekeza kuti athetse "zambiri" zotulutsa mpweya kuchokera ku migodi kaye, ndiyeno kukulitsa zoyesayesa zochepetsera mpweya wowonjezera kutentha.
Gregory Dipple, wofufuza wamkulu pamundawu, adauza MIT Technology Review: "M'zaka khumi zikubwerazi, migodi yowonongeka idzatithandiza kukhala ndi chidaliro ndi ukadaulo kuti tichepetse mpweya.Ndipo migodi yeniyeni ikuchitika.”
Malinga ndi a Kottke Ride Home Podcast host Jackson Bird (Jackson Bird) adanena kuti zinthuzi zikalowa m'nyanja kudzera mumtsinje, mineralization imapezekanso.Zamoyo za m'madzi zimagwiritsa ntchito ayoni kupanga zipolopolo ndi mafupa awo potsirizira pake kukhala miyala yamchere ndi zina.Mwala wa carbon.
Kusungirako mpweya ndi njira yofunikira yochepetsera kuchuluka kwa mpweya woipa m'mlengalenga.Popanda izo, sitingathe kukwaniritsa "zolinga zathu za carbon" ndikupewa zotsatira zoyipa kwambiri za nyengo.
Asayansi akufufuzanso momwe angagwiritsire ntchito zinyalala zochokera m’mafakitale ena amigodi monga faifi tambala, mkuwa, diamondi ndi platinamu kuti agwire carbon.Iwo akuganiza kuti pangakhale zinthu zokwanira kuletsa mpweya wonse wa carbon dioxide umene anthu anayamba watulutsapo, ndi zina zambiri, Mbalame inati.
Tsopano, zinthu zambiri zimakhazikika m'miyala yolimba yomwe siinayambe yawululidwapo ndi mpweya, yomwe ingayambitse kusintha kwa mankhwalawo.Ichi ndichifukwa chake asayansi omwe amaphunzira kuchotsa mpweya akuyesera kupeza njira zowonjezerera kuwonetseredwa ndikufulumizitsa kuyankha kwapang'onopang'ono kumeneku kuti asandutse zinyalala za migodi kukhala kulimbikitsa mphamvu zolimbana ndi vuto la nyengo.
Lipoti la MIT limafotokoza kuchuluka kwa njira zomwe zidayesedwa pofukula zida, kuzipera kukhala tinthu tating'onoting'ono, kenako ndikuzifalitsa m'zigawo zopyapyala, kenako kuzifalitsa kudzera mumlengalenga kuti ziwonjezeke kuwonekera.Zina zimafuna kutentha kapena kuwonjezera asidi kumagulu.Eos inanena kuti ena amagwiritsira ntchito mphasa za mabakiteriya kuti ayambitse kusintha kwa mankhwala.
"Tikuyang'ana kuti tifulumizitse njirayi ndikuisintha kuchoka ku mulu wa zinyalala za asibesitosi kukhala gawo lopanda vuto lililonse la carbonate," anatero katswiri wa sayansi ya sayansi ya zachilengedwe Jenine McCutcheon, yemwe akudzipereka kuti asandutse michira ya asibesitosi yomwe inasiyidwa kukhala Magnesium carbonate yopanda vuto.Ochita masewera olimbitsa thupi ndi okwera miyala amagwiritsa ntchito ufa woyera kuti agwire bwino.
Roger Aines, mkulu wa Carbon Program ku Lawrence Livermore National Lab, adauza MIT Technology Review kuti: "Uwu ndi mwayi waukulu, womwe sunapangidwe, ukhoza kuthetsa carbon dioxide yambiri."
Lipotilo likupitiriza kunena kuti ochirikiza njira yatsopanoyi amadandaula za ndalama ndi zoletsedwa za malo.Poyerekeza ndi njira zina zofota monga kubzala mitengo, njirayi ndi yokwera mtengo.Zingafunikenso malo ochulukirapo kuti afalitse zida zatsopano zomwe zidafukulidwa kuti zichepetse kwambiri mpweya wa carbon, zomwe zimapangitsa kuti zikhale zovuta kukwera.
Mbalame inanenanso kuti ndondomeko yonseyi ikhoza kuwononga mphamvu zambiri, ndipo ngati sichiyezedwa mosamala, ikhoza kuthetsa phindu la kugwidwa kwa carbon yomwe ikuyesera kupanga.
Pomaliza, pali zodetsa nkhawa zambiri zokhudzana ndi kawopsedwe kazinthu izi komanso chitetezo chozigwira.The MIT Technology Review inasonyeza kuti kufalitsa fumbi la asibesitosi pansi ndi / kapena kufalitsa fumbi kuti liwonjezeke kuyendayenda kwa mpweya kwachititsa ngozi za chitetezo kwa ogwira ntchito pafupi ndi anthu okhala pafupi.
Mbalame adatsimikiza kuti ngakhale izi zili choncho, pulogalamu yatsopanoyi ikhoza kukhala "njira yabwino yowonjezerapo mayankho ena ambiri, chifukwa tonse tikudziwa kuti sipadzakhala njira yothetsera vuto la nyengo."
Pali zinthu zambirimbiri kunja uko.Anthu ambiri adzachita chimodzimodzi, kapena pafupifupi chimodzimodzi, koma ndi kusiyana kobisika.Koma mankhwala ena ali ndi mankhwala oopsa amene angavulaze ifeyo kapena ana athu.Ngakhale ntchito yosavuta yosankha mankhwala otsukira mano ingatipangitse kukhala ndi nkhawa!
Zotsatira zina za nyengo yoipa zimatha kuwoneka - mwachitsanzo, theka la chimanga chathyathyathya ku Iowa chinasiyidwa pambuyo poti Midwestern United States idagunda kwambiri pa Ogasiti 10.

Zotsatira za kuyeza mita yothamanga zikuwonetsa kuti kuchuluka kwa nayitrogeni wosungunuka (DIN) kuchokera ku chigawo cha Mississippi kupita ku Gulf of Mexico kumasinthasintha kwambiri chaka chilichonse.Mvula yamphamvu idzatulutsa nayitrogeni wambiri.Kuchokera ku Lu et al., 2020, CC BY-ND
Kuchokera mu 1958 mpaka 2012, muzochitika zoopsa kwambiri (zomwe zimatanthauzidwa ngati 1% yolemera kwambiri ya zochitika za tsiku ndi tsiku), kuchuluka kwa mvula kunawonjezeka.Globalchange.gov
Denga lalikulu kwambiri padziko lonse lapansi litha kuwombana ndi South Georgia, zomwe zingawononge kwambiri nyama zakuthengo zomwe zimati kwawo.
Munjira zambiri, nkhani yaku Texas yazaka zana zapitazi ndi kukhulupirika kwa boma ku mfundo yakuti anthu amalamulira chilengedwe.
Kuyambira kuipitsidwa kwa mpweya komwe kumachitika chifukwa cha magalimoto ndi magalimoto mpaka kuchucha kwa methane, utsi wambiri womwe umayambitsa kusintha kwanyengo umawononganso thanzi la anthu.
