Zvisingaperi Zvisingazivikanwe: Climate Geoengineering
Kuputsa Climate Geoengineering Chikamu 1
Chikamu 2: Ocean Carbon Dioxide Removal
Chikamu 3: Kugadziriswa kweSolar Radiation
Chikamu 4: Kufunga nezve Hunhu, Kuenzana, uye Ruramisiro
Nyika iri kuwana pedyo uye pedyo kudarika chinangwa chemamiriro ekunze epasi rose chekudzikamisa kudziya kwepasi ne2℃. Nekuda kweizvi, kwave nekuwedzera kutarisa kwemamiriro ekunze geoengineering, nekabhoni dhaidhirodhi nzira dzekubvisa dzakabatanidzwa mukati yakawanda yeIPCC mamiriro.
Ngatidzokerei kumusoro: Chii chinonzi Climate Geoengineering?
Climate geoengineering ndiyo kudyidzana kwemaune kwevanhu nemamiriro ekunze ePasi mukuyedza kudzosera kumashure, kumisa, kana kuderedza kukanganiswa kwemamiriro ekunze. Iyo inozivikanwawo sekupindira kwemamiriro ekunze kana engineering yemamiriro ekunze, mamiriro ekunze geoengineering anoedza ku kuderedza kupisa kwepasi kuburikidza nekuchinja kwemwaranzi yezuva kana kuderedza atmospheric carbon dioxide (CO2) nekutora nekuchengetedza CO2 mugungwa kana panyika.
Climate geoengineering inofanirwa kutariswa chete pamusoro pe hurongwa hwekudzikisa hutsi - kwete sekugadzirisa chete dambudziko rekushanduka kwemamiriro ekunze. Nzira yekutanga yekurwisa shanduko yemamiriro ekunze ndeyekudzikisa kuburitswa kwekabhoni nemamwe magasi egreenhouse kana maGHG, kusanganisira methane.
Kukurumidzira kwakatenderedza dambudziko remamiriro ekunze kwatungamira mukutsvagisa uye kuita nezvemamiriro ekunze geoengineering - kunyangwe pasina hutongi hunoshanda.
Mamiriro ekunze geoengineering mapurojekiti achave nemhedzisiro yenguva refu papasi, uye inoda a bumbiro remitemo yetsika nesainzi. Mapurojekiti aya achabata ivhu, nyanza, mhepo, uye vese vanovimba nezviwanikwa izvi.
Kumhanyira kunzira dzemamiriro ekunze geoengineering pasina kufanoona kunogona kukonzera kukuvadza kusingafungirwe uye kusinga gadziriswe kune ecosystem yepasirese. Mune zvimwe zviitiko, mamiriro ekunze geoengineering mapurojekiti anogona kushandura purofiti zvisinei nekubudirira kweprojekiti (semuenzaniso nekutengesa makiredhiti kumapurojekiti asina kubvumidzwa uye asina kubvumidzwa pasina rezinesi rekugara), kugadzira zvinokurudzira zvingasaenderana nezvinangwa zvemamiriro ekunze pasi rose. Sezvo nharaunda yepasirese ichiongorora mamiriro ekunze geoengineering mapurojekiti, kubatanidza uye kugadzirisa zvinonetsa zvevanobatanidzwa pamwe chete nehurongwa hunoda kuiswa pamberi.
Izvo zvisingazivikanwe uye zvingangoitika zvisingatarisirwe mhedzisiro yemamiriro ekunze geoengineering mapurojekiti anosimbisa kukosha kwekujeka uye kuzvidavirira. Sezvo mazhinji emapurojekiti aya ari epasi rose muhukuru, anofanirwa kutariswa uye kuwana zvinogoneka zvinokanganisa uku achienzanisa scalability nemutengo - kuve nechokwadi chekuenzana uye kuwana.
pari mapurojekiti mazhinji ari muchikamu chekuyedza, uye mamodheru anoda kuoneswa pamberi pemakurisa-akaitwa kuti aderedze zvisingazivikanwe uye zvisingatarisirwe mhedzisiro. Kuedza kweOcean uye zvidzidzo zvemamiriro ekunze geoengineering mapurojekiti akaganhurirwa nekuda kwekunetseka nekutarisa uye kuoneswa kwekubudirira kwemapurojekiti senge chiyero uye kusingaperi kwekubvisa kabhoni dhaikisaidhi. Kugadzira kodhi yekuzvibata uye zviyero kwakakosha kune mhinduro dzakaenzana kudambudziko remamiriro ekunze, kukoshesa kururamisira kwezvakatipoteredza uye kuchengetedzwa kwezviwanikwa.
Climate geoengineering mapurojekiti anogona kukamurwa kuita mapoka makuru maviri.
Zvikamu izvi kubvisa carbon dioxide (CDR) uye solar radiation modification (SRM, inonziwo solar radiation management kana solar geoengineering). CDR inotarisa kushanduka kwemamiriro ekunze uye kudziya kwepasi rose kubva kune greenhouse gasi (GHG) maonero. Mapurojekiti anotsvaga nzira dzekuita kuderedza carbon dioxide parizvino mumhepo uye woichengeta munzvimbo dzakaita semiti, maumbirwo ematombo, kana ivhu kuburikidza nemasikirwo uye enjiniya maitiro. Aya mapurojekiti anogona kupatsanurwa kuita yegungwa-based CDR (dzimwe nguva inodaidzwa kuti marine kana mCDR) uye pasi-based CDR, zvichienderana nemidziyo inoshandiswa uye nzvimbo yekuchengetera kabhoni dhaidhi.
Tarisa yechipiri blog mune ino nhevedzano: Yakabatwa muBlue Blue: Ocean Carbon Dioxide Removal kune rondedzero yemapurojekiti emugungwa eCDR.
SRM inonangana nekudziya kwepasirese kubva pakupisa uye solar radiation maonero. Mapurojekiti eSRM anotarisa kubata mabatiro anoita zuva nenyika nekuratidza kana kuburitsa chiedza chezuva. Mapurojekiti ane chinangwa chekudzikisa huwandu hwechiedza chezuva chinopinda mumhepo, zvichizodzikisa tembiricha yepasi.
Tarisa yechitatu blog mune ino nhevedzano: Planetary Sunscreen: Solar Radiation Modification kuti udzidze zvakawanda pamusoro pezvirongwa zveSRM zvakarongwa.
Mune mablogiki anotevera mune ino nhevedzano, isu tichagadzirisa mamiriro ekunze geoengineering mapurojekiti muzvikamu zvitatu, tichiisa purojekiti yega yega se "yakasikwa," "yakagadziridzwa zvisikwa," kana "mechini nemakemikari".
Kana akabatanidzwa nekudzikamisa kuburitsa gasi regreenhouse, mapurojekiti emamiriro ekunze geoengineering ane mukana wekubatsira nharaunda yepasirese kudzikisira kukanganisa kwekushanduka kwemamiriro ekunze. Zvakadaro, mhedzisiro isingatarisirwe yekugadziriswa kwemamiriro ekunze kwenguva refu inoramba isingazivikanwe uye ine mukana wekutyisidzira zvipenyu zvepasi redu uye nzira iyo isu, sevane chekuita nePasi, tinodyidzana nepasi. Iyo yekupedzisira blog mune ino nhevedzano, Climate Geoengineering uye Yedu Ocean: Kufunga Ethics, Equity, uye Justice, inoburitsa nzvimbo idzo kuenzana nekururamisira kwakanangana nenhaurirano iyi mubasa rakapfuura reTOF, uye uko nhaurirano idzi dzinoda kuenderera mberi tichishandira nzira inonzwisiswa pasi rose uye inogamuchirwa nesainzi yemitemo yemapurojekiti ekugadzira mamiriro ekunze.
Sainzi nekururamisira zvakapindirana mudambudziko remamiriro ekunze uye zvinotariswa zvakanyanya tandem. Iyi nzvimbo itsva yekudzidza inoda kutungamirirwa nekodhi yemaitiro inosimudzira kunetseka kwevose vane chekuita kuti vawane nzira yakaenzana yekuenda mberi.
Climate geoengineering inoita zvivimbiso zvinokwezva, asi inopa kutyisidzira chaiko kana tikasatarisisa maitiro ayo enguva refu, kutendeseka, scalability, uye kuenzana.
Mazwi Akakosha
Natural Climate Geoengineering: Zvirongwa zvechisikigo (zvakasikwa-zvakavakirwa mhinduro kana NbS) zvinotsamira pane ecosystem-yakavakirwa maitiro uye mabasa anoitika nekugumira kana kusapindira kwevanhu. Kupindira kwakadaro kunowanzo kugumira pakusima miti, kudzoreredza kana kuchengetedza zvipenyu.
Yakanatsiridzwa Natural Climate Geoengineering: Mapurojekiti echisikigo akakwenenzverwa anotsamira pane ecosystem-based maitiro uye mabasa, asi anotsigirwa neyakagadzirwa uye yenguva dzose kupindira kwevanhu kuwedzera kugona kwechisikigo kukwevera pasi kabhoni dioxide kana kugadzirisa chiedza chezuva, sekupomba zvinovaka muviri mugungwa kumanikidza algal blooms izvo zvinozoita. kutora kabhoni.
Mechanical uye Chemical Climate Geoengineering: Mechanical uye makemikari geoengineered mapurojekiti anovimba nekupindira kwevanhu uye tekinoroji. Aya mapurojekiti anoshandisa maitiro emuviri kana emakemikari kuita shanduko inodiwa.
