Imililo yequbula, ezenzeka ngokwemvelo emahlathini nasezindaweni ezinotshani, ziyingxenye ebalulekile yomjikelezo wekhabhoni womhlaba wonke, okhipha cishe u-2GtC (amathani ama-metric ayizigidi eziyizinkulungwane ezingu-2 / 2 trillion kg wekhabhoni) emkhathini unyaka ngamunye.Ngemva komlilo wequbula, uhlaza luyakhula futhi futhi lungamunca ngokugcwele noma ngokwengxenye ikhabhoni ekhishwa ngesikhathi sokusha, kwakheka umjikelezo.
“Ukukhishwa kwekhabhoni yomlilo wasendle kuyingxenye ebalulekile yomjikelezo wekhabhoni womhlaba wonke, ngokukhishwa kwekhabhoni yomlilo wasendle minyaka yonke okulingana cishe no-20% wekhabhoni ekhishwa yi-anthropogenic.Imililo yamahlathi ibaluleke kakhulu.”U-Academician He Kebin, umqondisi we-Institute of Carbon Neutrality, eNyuvesi yaseTsinghua, kanye nomphathi we-Institute of Environment and Ecology, iSikole Seziqu Zomhlaba sase-Shenzhen.
Uma umlilo wequbula ungena endaweni yemvelo ecebile ngekhabhoni kanye nomsebenzi onamandla we-carbon sink njenge-peatland nehlathi, awukhiqizi kuphela inani elikhulu lokukhishwa kwekhabhoni, kodwa futhi uholela ezinhlekeleleni zemvelo ezingathi sína njengomlilo we-peatland, ukugawulwa kwamahlathi kanye nokucekelwa phansi kwehlathi. , okwenza kube nzima ukumunca ngokugcwele ikhabhoni ekhishwe inqubo yokushiswa komlilo wequbula, futhi ngisho nokuvimbela ukululama ngokushesha nokwakhiwa kabusha kwe-ecosystem kanye nokwenza buthaka umthamo wokucwilisa ikhabhoni we-ecosystem yasemhlabeni.Imililo yequbula eyedlulele ayigcini nje ngokubhubhisa imvelo nezinhlobonhlobo zezinto eziphilayo, kodwa futhi ikhulula amanani amakhuluukungcola okuyingozikanye namagesi abamba ukushisa emkhathini, okuzophazamisa isimo sezulu somhlaba wonke kanye nempilo yabantu.
Phakathi nemicimbi efana nemililo yequbula, ukuqhuma kwentaba-mlilo neziphepho zothuli, intuthu kanye/noma okunye ukungcoliswa kwezinhlayiyana okukhiqizwa ngaphandle kungangena endaweni yasendlini futhi kukhuphule amazinga e-particle yasendlini.Ubukhulu kanye nokuvama kwemililo yequbula kuye kwanda eminyakeni yamuva, okuveza izakhamuzi eziningi ukuba zibheme nomlotha kanye nezinye izinto ezibangelwa ukusha.Ngaphezu kwalokho, lapho umlilo wequbula uvutha phakathi komphakathi,amakhemikhali aphuma ezakhiweni ezivuthayo, ifenisha, nanoma yiziphi ezinye izinto ezisendleleni adedelwa emoyeni.
Izintaba-mlilo ziqhuma ngaphandle kwesixwayiso, zikhiphe umlotha namanye amagesi ayingozi okwenza kube nzima ukuphefumula.Imimoya enamandla kanye namaseli okuduma kwezulu angabangela iziphepho zothuli, ezingase zenzeke kulo lonke elase-United States kodwa zivame kakhulu eningizimu-ntshonalanga ye-United States.
Yini engenziwa?
- Gcina iminyango namafasitela evaliwe phakathi nemicimbi enzima kangaka yokungcola kwangaphandle.Uma ucasukile ekhaya, funa indawo yokukhosela kwenye indawo.
- Egunjini lapho uchitha khona isikhathi sakho esiningi, cabanga ukusebenzisa iisihlanzi somoya.
- Cabangela izihlungi ezisebenza kahle kakhulu zokushisisa, ukungena komoya kanye namasistimu e-HVAC.Isibonelo, izihlungi ezifinyelelayoI-HEPA 13noma ngaphezulu.
- Phakathi nale micimbi yokungcoliswa kwemvelo, shuna isistimu yakho ye-HVAC noma i-air conditioner ukuze uguqule ukulungiselelwa ekujikelezeni kabusha komoya ukuze kungabi bikho umoshi nezinye izinhlayiya.
- Futhi, cabanga ukuthenga imaskhi engu-N95 ukuvikela amaphaphu akho entuthuni nakwezinye izinhlayiya ezinhle.
- Uma ikhwalithi yomoya wangaphandle iba ngcono, vula iwindi noma umoya ohlanzekile ohlelweni lwe-HVAC ukuze uvule igumbi, ngisho nangesikhashana.
Sekungamashumi eminyaka, iCalifornia ihlushwa imililo yequbula evame ukuvela ehlobo, elawulwa imililo yequbula eqhubeka nokubhebhetheka.Kodwa imililo yequbula iye yaba yingozi kakhulu eminyakeni yamuva.NgokoMnyango Wezamahlathi Nokuvikelwa Komlilo waseCalifornia, imililo yequbula engu-12 kwengu-20 emikhulu emlandweni wesifunda yenzekile eminyakeni emihlanu edlule, yashisa isamba esihlanganisiwe esingu-4% sendawo yonke yaseCalifornia, okulingana naso sonke isifunda sase-Connecticut.
Ngo-2021, imililo yasendle yaseCalifornia yakhipha amathani ayizigidi eziyi-161 e-carbon dioxide, okulingana cishe namaphesenti angama-40 weqoqo lezinto ezikhishwa yizwe ngo-2020.Njengesinye sezifundazwe esihlaselwe kakhulu imililo yequbula, iCalifornia ihamba phambili ohlwini lokungcoliswa komoya.Ngokusho kwedatha, amadolobha amahlanu ase-US anokungcola okunengxenye enkulu kakhulu ngo-2021 wonke aseCalifornia.
Kungakhathaliseki ukuthi ngenxa yabo, noma impilo yesizukulwane esilandelayo sezingane, inkinga yokungcola okubangelwa isimo sezulu esibi kakhulu iyaphuthuma.
Umkhankaso we-Breathe Life, owasungulwa yi-WHO, i-UN Environment kanye neClimate and Clean Air Coalition yokunciphisa Ukungcola Kwesimo Sezulu Sesikhathi Esifushane, inhlangano yomhlaba wonke yokuqonda kangcono umthelela wokungcoliswa komoya empilweni yethu naseplanethi yethu, kanye nokwakha inethiwekhi. wezakhamizi, abaholi bamadolobhakazi nabakazwelonke kanye nabasebenzi bezempilo ukuze baqhubekisele phambili ushintsho emiphakathini.Ukuze sithuthukise umoya esiwuphefumulayo.
Ukungcoliswa komoya kuhlobene eduze nokushintsha kwesimo sezulu.Isizathu esiyinhloko sokushintsha kwesimo sezulu ukushiswa kwezinto ezimbiwa phansi, okuyimbangela enkulu yokungcoliswa komoya.I-United Nations Conference on Climate Change isixwayise ngokuthi ugesi wamalahle kumele uphele ngo-2050 uma sifuna ukunciphisa ukufudumala komhlaba ku-1.5oC.Ngaphandle kwalokho, singase sibhekane nenkinga enkulu yesimo sezulu eminyakeni engama-20 nje kuphela.
Ukuhlangabezana nezinjongo zeSivumelwano SaseParis kusho ukuthi ngo-2050, cishe izimpilo eziyisigidi zingasindiswa emhlabeni wonke unyaka ngamunye ngokunciphisa ukungcoliswa komoya kuphela.Izinzuzo zezempilo zokubhekana nokungcoliswa komoya zibalulekile: emazweni angu-15 akhipha amagesi abamba ukushisa kakhulu, umthelela wezempilo wokungcoliswa komoya ulinganiselwa ngaphezu kuka-4% wesamba somkhiqizo wabo wasekhaya.
