Iphesheni elincane lokushisa okushisa. Iyini igesi lokushisa?

Umsebenzi wokukhiqiza womuntu uhlanganisa imiphumela eyingozi emkhathini. Lesi sici sesivele sibe yi-banality futhi ukunakekelwa kukhokhwa kuphela ngabachwepheshe emkhakheni wezemvelo. Phakathi naleso sikhathi, ukukhishwa okulimazayo kuphakamisa imibuzo ebaluleke kakhulu ezinhlanganweni ezihilelekile ekuguqulweni kwesimo sezulu emhlabeni wonke. Kuhlu lwezinkinga eziyinkimbinkimbi kakhulu emibuthanweni enikezwe imvelo, i-greenhouse gas ibonakala njengenye yezinto eziyingozi kakhulu ezithinta umoya kanye ne-biota. Iqiniso liwukuthi ama-gaseous compounds alolu hlobo awakwazi ukudlula ukushisa kwamafutha okushisa, okubangela ukushisa komkhathi. Kunemithombo eminingi yokwakhiwa kwamagesi anjalo, kuhlanganise nezimo eziphilayo. Futhi manje kubalulekile ukufunda okuningi mayelana nokwakhiwa kokuhlanganiswa okushisa.

Umswakama wamanzi njengegesi elikhulu lokushisa

AmaGesi aloluhlobo afaka ama-60% wevolumu yenani lezinto ngenxa yokuthi kudala umphumela wokubamba ukushisa. Njengoba izinga lokushisa lomhlaba landa, ukukhuphuka nokuhlushwa kwamanzi omkhathi emkhathini nakho kwanda. Ngesikhathi esifanayo, i-humidity level level isala, okwenza kube nomphumela wokushisa okushisa. I-essence engokwemvelo, okuyinto igesi lokushisa elinezimo ezinomoya, ngokungangabazeki kunezici ezinhle eziphathelene nokuhlelwa kwemvelo kwemvelo. Kodwa kukhona nemiphumela emibi yale nqubo. Iqiniso liwukuthi ngokumelene nesizinda somswakama okhulayo, kunomthelela okhunjini wefu, obonisa imisebe eqondile yelanga. Ngenxa yalokho, sekuvele umphumela wokulwa nokushisa, lapho ubukhulu bemisebe yomoya obufudumele futhi, ngokufanayo, ukushisa komkhathi kunciphisa.

I-carbon dioxide

Phakathi kwemithombo eyinhloko yalolu hlobo lokukhishwa yizimpukane ze-volcanic, imisebenzi yabantu nezinqubo ezenzeka ku-biosphere. Imithombo ye-anthropogenic ihlanganisa ukushisa kwezinto zokufakelwa kwamafutha kanye ne-biomass, izinqubo zezimboni kanye nezinye izici eziholela ekusungulweni kwe-carbon dioxide. Leli gesi elibamba ukushisa elibamba iqhaza ekusebenzeni kwe-biocenosis. Uyena oqinile kakhulu ngokuhlala emkhathini. Ngokolwazi oluthile, ukuqoqwa okuqhubekayo kwe-carbon dioxide emigqeni yomoya kunciphise ingozi yemiphumela hhayi nje kuphela kokulingana endaweni ye-biosphere, kodwa futhi nokuba khona kwentuthuko yabantu njengomuntu wonke. Ukumelwa okunjalo kuyisisusa esiyinhloko sokuthuthukisa izinyathelo eziphikisana nomphumela wokushisa okushisa.

IMethane

Le gas igcinwa emkhathini iminyaka engaba ngu-10. Ngaphambilini kwakucatshangwa ukuthi umphumela we-methane ekuvuseleleni umphumela wokushisa unamaphesenti angu-25 ephakeme kune-carbon dioxide. Kodwa ucwaningo lwesayensi lwamuva luye lwaholela imiphumela engapheli kakhulu - kwaba khona ukuthi umthelela ongase ube nalo waleli gesi wawucatshangelwa. Noma kunjalo, isimo sinciphisa isikhathi esifushane lapho umkhathi ugcina imethane. Igesi lokushisa lalo hlobo livela ngenxa yomsebenzi we-anthropogenic. Lokhu kungaba umlimi welayisi, ukuvuthwa kokugaya ukudla, ukunciphisa ama-massifs ehlathini, njll Ngokwezinye izifundo, ukukhula okujulile kokuhlushwa kwe-methane kwenzeka enkulungwaneni yokuqala yeminyaka yethu. Izinto ezinjalo zazihlobene nokukhuliswa kwezinkomo zokuzalanisa kanye nokukhiqizwa kwezolimo, kanye nokushiswa kwamahlathi. Emakhulwini eminyaka alandelayo, izinga lokugonywa kwe-methane lahlehla, nakuba ezinsukwini zethu kukhona umkhuba oguqukayo.

I-ozone

Ekubunjweni kokuhlanganiswa kwama-greenhouse gaseous akuyona nje eyingozi kusukela ekubukeni kwezingxenye zezinguquko zesimo sezulu , kodwa futhi izingxenye ezizuzisayo. Lokhu kufaka i-ozone, evikela umhlaba kusukela ekukhanyeni kwe-ultraviolet. Noma kunjalo, lapha futhi akusikho konke okungaqondile. Ososayensi bahlukanisa leli gesi zibe yizigaba ezimbili - i-tropospheric ne-stratospheric. Ngokuqondene nomuntu wangaphambili, kungaba yingozi ngenxa yobuthi bayo. Ngokuhambisana nalokhu, okuqukethwe okwandisiwe kwezinto ezithinta i-tropospheric kunomthelela ekukhuleni komphumela wokushisa. Kulezi zingqimba ze-stratospheric ukuvikelwa okuyisisekelo ngaphambi kwemiphumela yomswakama omazayo. Ezindaweni lapho igesi lokushisa lalo hlobo lihlushwa khona, kutholakala imiphumela enamandla ezitshalweni ezibonakalayo ekucindezelweni kwamandla we-photosynthetic.

Ukuphikisana nomphumela wokushisa

Kunezindawo eziningana lapho umsebenzi uqhubeka khona ukuqukatha inqubo. Phakathi kwezinyathelo eziyinhloko, ukusetshenziswa kwamathuluzi okulawula ukusebenzisana kwamadivayisi okugcina kanye nokucwilisa kwamagesi okushisa kugcizelelwe. Ngokuyinhloko, izivumelwano zemvelo ezingeni lendawo zinezela ekuthuthukisweni okusebenzayo kwamahlathi. Lapha kubalulekile ukuqaphela imisebenzi yokuthungwa kwamahlathi, okuyinto esikhathini esizayo ezovumela ukunciphisa umphumela wokushisa. Igesi elikhishwe emkhathini kusuka ezindaweni zokukhiqiza libuye linciphise ezimbonini eziningi. Ukuze kube njalo, izinyathelo ziqaliswa ukunciphisa ukukhishwa kwezokuthutha, ezindaweni zokukhiqiza, ezitshalweni zamandla, njll. Ukuze kube sekugcineni, izindlela zokwenza izindlela zokucubungula amafutha kanye nezinhlelo zokususwa kwegesi ziyasungulwa. Isibonelo, maduzane uhlelo lokubuyisela kabusha luqalisiwe, ngenxa yamabhizinisi okwenza ngcono izinqubo zokulahlwa kwemfucuza.

Isiphetho

Emisebenzini yokwakheka komphumela wokushisa, imisebenzi yabantu ayiyona indima ebaluleke kakhulu. Lokhu kubonakala kusukela kwingxenye yemithombo yegesi ekhishwa imithombo ye-anthropogenic. Noma kunjalo, ukukhishwa okulimazayo kuyingozi kakhulu emkhathini. Ngakho-ke, izinhlangano zemvelo zithatha igesi lokushisa njenge-factor of negative climate change. Ngenxa yalokho, imali isetshenziselwa ukuhlanganisa ukusakazeka nokuqoqwa kwezidakamizwa eziyingozi ekwenzeni ukwandisa ingozi yokufudumala kwembulunga yonke. Futhi ukulwa nokukhishwa okulimazayo kwenziwa ngezindlela ezihlukahlukene. Lokhu akusebenzi nje kuphela kumafektri namabhizinisi, kodwa futhi nemikhiqizo ehloselwe ukusetshenziswa komuntu ngamunye.
