I-Greenhouse Effect: Ukuqonda Izimbangela, Imiphumela, kanye Nezixazululo

Kuningi okushiwoyo ngomphumela wokushisa okushisa okushisayo, muva nje njengokungathi kuyinto engeyinhle, okuthile okungasidalela izinkinga eziningi kubantu nakubo bonke abanye abantu abahlala emhlabeni. Kepha siyazi yini ukuthi kubangelwa yini nokuthi kubaluleke kangakanani empilweni?

Ngemuva kwalokho ngizochaza Uyini umphumela we-greenhouse futhi ubangelwa yini? ukuze, ngale ndlela, ukwazi ukuqonda kakhudlwana iplanethi esisithintile.

Uyini umphumela wokushisa?

Kuyindlela okwenziwa ngayo lokhu Imisebe ekhishwa elangeni imuncwa amagesi abamba ukushisa o I-GHG (umhwamuko wamanzi, i-carbon dioxide, i-methane, i-nitrogen oxide, i-ozone ne-chlorofluorocarbon) itholakala emkhathini futhi ikhanya kuzo zonke izinhlangothi. Eminye yale misebe idonswa indawo engaphansi komhlaba, ukuze izinga lokushisa eliphakathi nendawo likhuphuke, livumele ukuphila kube khona. Ngaphezu kwalokho, kubalulekile ukwazi Imiphumela yokufudumala komhlaba njengengxenye yalolu hlelo.

Nokho, imisebenzi yabantu iye yaqinisa le nqubo yemvelo, ngaleyo ndlela kubhebhethekise ukufudumala kwembulunga yonke. Ungafunda kabanzi mayelana nokuthi isimo sezulu siye sathinteka kanjani esihlokweni mayelana lapho abantu beqala ukuthonya isimo sezulu nangaye i-anthropogenic greenhouse effect kanye nomthelela wayo esimweni sezulu.

Unamiphi imiphumela?

Umphumela wemvelo we-greenhouse uvumele impilo njengoba sazi ukuthi ikhona futhi ithuthuke; Kodwa-ke, njengoba abantu begawula amahlathi, basebenzisa izinto zokubasa ezimbiwa phansi, bangcolise, futhi benganaki iplanethi, ukugcwala kwama-GHG, ikakhulukazi isikhutha, kuye kwanda kuphela. Lokhu futhi kuhlobene ne- umsuka wokufudumala komhlaba, okuye kwaholela ekwenyukeni kwamazinga okushisa.

Ngenxa yalokho, imisebe eyengeziwe ibuyiselwa ngaphezulu, okudala i- ukwanda kwezinga lokushisa elisho, the ukuncibilika kwezingqimba zeqhwa ezisemazweni, okungadala ukuthi amazinga olwandle anyuke, the kusengaphambili kwehlane, izinguquko ezinkathini zonyaka, futhi izinguquko emaphethini emvula, okungabonwa ku imiphumela yokuguquguquka kwesimo sezulu esizayo.

I-greenhouse effect iyinqubo okufanele ihlale ingokwemvelo. Ngakho-ke, kubalulekile ukuyeka ukubhubhisa iplanethi, kucatshangelwa umthelela wokuncibilika kweqhwa emhlabeni.

Izimbangela zomphumela we-greenhouse

Izimbangela eziyinhloko zomphumela we-greenhouse zingahlukaniswa kanje:

• Ukukhishwa kwamagesi abamba ukushisa: Ukushiswa kwezinto zokubasa ezimbiwa phansi ezifana nowoyela, igesi yemvelo namalahle kukhipha amagesi afana ne-carbon dioxide (CO2), i-methane (CH4) kanye ne-nitrous oxide (N2O) emkhathini.
• Ukuqedwa kwamahlathi: Ukugawulwa kwezihlahla ngokungakhethi kuqeda ikhono lezimila lokumunca isikhutha emkhathini. Ubudlelwano phakathi kokugawulwa kwamahlathi futhi kuyakhathaza.
• Ukulima: Ukufuywa kakhulu, ukusetshenziswa kukamanyolo kanye nokushiswa kwemfucuza yezolimo kudala inqwaba yamagesi abamba ukushisa, okuxhumene imiphumela yokufudumala kwembulunga yonke ezimpandeni zezitshalo.
• Izimboni nezinqubo zokukhiqiza: Ukukhiqizwa kwezinto ezifana nensimbi noma usimende, phakathi kokunye, kukhulula inani elikhulu le-carbon dioxide, ehlanganisa umthelela we Umphumela we-Tyndall.
• Ezokuthutha: Izimoto ezisebenzisa izibaso ezimbiwa phansi zinomthwalo wemfanelo engxenyeni enkulu yokukhishwa kwesisi esibamba ukushisa, okunomthelela umphumela wesiqhingi sokushisa sasemadolobheni.

Imiphumela ye-greenhouse effect

Umphumela we-greenhouse ubangele izinkinga eziningana zemvelo. Phakathi kwemiphumela ebaluleke kakhulu yilezi:

• Ukushisa kakhulu komhlaba: Ukwenyuka kwezinga lokushisa eMhlabeni kulethe izinguquko zesimo sezulu eziningana ezingalimaza iplanethi nezakhamuzi zayo, futhi zihlobene imiphumela yokufudumala kwembulunga yonke.
• Ukuncibilika kwe-glacier: Ukushesha kokuncibilika kweqhwa ezindaweni ezishisayo kubangela ukuphakama kwamanzi olwandle, okubeka ukusinda kwamadolobha asogwini engozini.
• Imicimbi yesimo sezulu esibi kakhulu: Ukwanda kweziphepho, iziphepho, isomiso namagagasi okushisa kuyizibonelo zokushintsha kwesimo sezulu okubangelwa umphumela we-greenhouse, ohlobene ukulwa nokuguquguquka kwesimo sezulu.
• Umthelela kuma-ecosystems: Izinhlobo eziningi zezilwane zisengozini ngenxa yokuguqulwa kwezindawo zokuhlala kanye nokuncipha kwemithombo yemvelo. Ungathola imininingwane eyengeziwe mayelana nomthelela kuma-ecosystem esihlokweni esimayelana .

Indlela yokugwema umphumela we-greenhouse?

Okuwukuphela kwendlela yokunciphisa umphumela we-greenhouse obangelwa imisebenzi yabantu ukunciphisa Ukukhishwa kwamagesi abamba ukushisa. Ngezansi ezinye izinyathelo ongazithatha:

• Ukushintshela emandleni avuselelekayo: Khuthaza ukusetshenziswa kwamandla elanga, umoya, neminye imithombo yamandla avuselelekayo angakhiphi amagesi abamba ukushisa.
• Ukulondolozwa kwehlathi: Vikela futhi ubuyisele imvelo yehlathi ebalulekile ekumunceni i-CO2 emkhathini, okubalulekile ekulweni .
• Imfundo nokuqwashisa: Yazisa umphakathi ngokubaluleka kokunakekela imvelo nezinye izindlela ezisimeme, kanye .
• Ukuqamba okusha kwezobuchwepheshe: Tshala imali kubuchwepheshe obunciphisa ukukhishwa kwegesi futhi bukhuthaze ukusebenza kahle kwamandla.

Njengoba sithatha izinyathelo ezisheshayo, singanciphisa umphumela we-greenhouse futhi sivikele iplanethi ezizukulwaneni ezizayo. Mayelana nalokhu, ukubambisana kwamazwe ngamazwe nokuzibophezela kwawo wonke umuntu ekubuyiseleni umonakalo odaliwe kubalulekile.
