Tukunga tenei ... GHG - Greenhouse Gas

hau Greenhouse - he ranunga o te maha haurehu kōhauhau mārama e kore e e nui haere waiariki radiation i te whenua. Ko te tupu o te kukū arata'i ki te huringa āhuarangi ao, me te tina heke. He maha ngā momo o te haurehu kati kōtuhi matua. Ko te kukū kōhauhau o ia o ratou i roto i to ratou pānga i runga i te pānga waiariki.

Ko te momo matua o

He maha ngā momo o matū haurehu waihā no ki te haurehu tino nui kōtuhi:

• kohu wai;
• hauhā;
• waikura Sinks;
• mewaro;
• CFCs;
• PFCs (perfluorocarbons);
• HFCs (hydrofluorocarbons);
• SF6 (whanariki hexafluoride).

E pā ana ki te 30 ngā momo o ngā haurehu meinga te pānga kōtuhi. Pānga i runga i ngā tukanga waiariki matū whenua ia faaitoito i runga i te tau, me te kaha ia urupare rāpoi ngota. Na roto i te āhua o te tupu o ngā haurehu kati kōtuhi i roto i te huru e wehea ki tūturu me horonga.

kohu wai

He hau kōtuhi noa he kohu wai. Ko tōna nui i roto i te huru te mea nui atu te kukū o te hauhā. Ko o te take mai tūturu Water kohu: e kore e taea e ki te whakapiki ake i tona mana i roto i te taiao āhuatanga o waho. Regulates te maha o ngā rāpoi ngota wai whakaeto moana pāmahana me te rangi.

āhuatanga motuhake nui o te kohu wai - whakataka faatanoraa pai ki te hauhā. Kei te kitea te reira e te kati kōtuhi, pōreareatanga i te tuku o te hauhā nui haere te pā ana ki rua e tika ana ki te mana o te whakaetonga o ngā rāpoi ngota wai.

Ko te kupu, kohu wai rite te hau kōtuhi - ko te whakakōkī warming āhuarangi horonga kaha. Hei tirohia ona pānga i runga i te kati kōtuhi he tukanga anake i roto i ngā ki te āhuatanga o te hononga pai ki te hāorarua waro. I tahaki, e kore e te kohu wai arahi ki huringa ao.

hauhā

noho te reira i te wahi ārahi i roto i te haurehu kati kōtuhi o te take mai horonga. Kei te pumau te reira e pā ana ki 65% o te mahana te ao e tika ana ki te hua i roto i te pira o te hauhā i te kōhauhau o te whenua. Ko te take matua i roto i te whakanui ake i te kukū o te hau ko, o te akoranga, whakaputa me ngā mahi tangata hangarau.

Fuel ngingiha e wahi tuatahi (86% o te katoa tukunga hauhā) i roto i nga puna o te tukunga o te hauhā ki te kōhauhau. Hoki ētahi atu take ngā te tahunga o te koiora - te nuinga ngahere - me te pira ahumahi.

Waro haurehu kati - ko te kaha whui whai hua te nuinga o te mahanatanga o te ao. Kia i te huru o te hauhā hanga he ara roa i roto i ona papa katoa. huaina te wa e hiahiatia ana ki te tango 65% o te hāorarua waro i te putea rangi ko te wā whai hua o te noho. haurehu kati kōtuhi i roto i te huru rite te hauhā rongoa hoki 50-200 s. Ko te reira i te roanga tiketike o te aroaro o te hauhā i roto i te taiao whai wāhi nui i roto i te kati kōtuhi.

mewaro

Ki te kōhauhau tikanga māori, me te horonga. Ahakoa te meka i tona kukū ko moni nui raro o te hauhā, te mewaro mahi rite te hau kōtuhi atu tino. 1 mewaro rāpoi ngota e arotakea i te huarahi o te kati kōtuhi ko 25 nga wa kaha atu i te hauhā rāpoi ngota.

I tēnei wā, kei te huru e pā ana ki te 20% te mewaro (i 100% o te haurehu kati kōtuhi). Āwenewene tomo mewaro nga pira rangi i te ahumahi. whakaaro Natural hanganga hau tikanga te whāwehe nui o ngā matū waro, me te ngingiha nui o koiora ngahere.

waikura nitric (ahau)

whakaaro waikura Nitrous te rite te toru o nga hau tino nui kōtuhi. Ko tēnei rauemi he pānga tōraro i runga i te pekerangi. Kei te kitea te reira i pā ana ki 6% o te kati kōtuhi e kiia hoki te monovalent hauota waikura. mahi pūhui 250 wa kaha atu i te hauhā.

puta Dinitrogen monoxide i te kōhauhau o te whenua i roto i te ara tūturu. He he rōpū pai ki te apa pekerangi: te nui te kukū o te waikura, te teitei te tohu o te whakangaromanga. I runga i te ringa kotahi, tukanga pekerangi kēkeno whakaiti te pānga kōtuhi. I te wa ano, he nui atu mōrearea mō te ao te radiation iraruke. Kei te ako te tūranga o te hau ārai i roto i te tukanga warming ao, a ka kua wehea nga whakaaro o tohunga i runga i tenei kaupapa.

PFCs ko HFCs

Waiwaro ki whakauru wāhanga o köwhai i roto i te hanganga rāpoi - he haurehu kati kōtuhi o te tangata. Ko te pānga o taua matū i runga i ngā tukanga warming ao tahi ko e pā ana ki 6%.

PFCs ki te huru hua i roto i te hanga o te konumohe, taputapu hiko, me te ngā whakarewa matū. HFCs He pūhui i roto i nei te wāhanga whakakapi te hauwai e kōnakonako. Whakamahia i roto i te whakangao me i roto i aerosols ki te whakakapi pekerangi tokoiti matū. A ani i te pūmanawa warming ao tiketike, engari he reira haumaru hoki te huru o te whenua.

hexafluoride whanariki

Whakamahia rite rauemi mātao i roto i te ahumahi mana hiko. Hononga mo te wa roa ahu ki tohe i roto i te huru, e arata'i ki te absorption roa, me te whānui o te hihi pōkākā. Ahakoa he nui iti o te whanariki hexafluoride tino pā te āhua o te āhuarangi i roto i te heke mai.

pānga kōtuhi

Ka taea te kitea te tukanga i runga i te whenua e kore e anake, engari i runga i te Venus muri. Kei te wā tōna huru tito katoa o te hauhā, kua arahina nei ki te hua i roto i te pāmahana mata ki 475 nekehanga. Tohunga whakapono e ki te karo i te taua e pa awhinatia te whenua nga moana: wāhanga te ngongo hauhā, te āwhina ratou whakakore i te reira i te rangi ambient.

Tukunga o ngā haurehu kati kōtuhi i roto i te whai wāhi poraka huru ki radiation waiariki, e arata'i ki te hua i roto i te pāmahana i runga i te whenua. warming Global kia arahi ki hopearaa mamafa i te puka o te whakanui ake i te rohe o te moana, ake auau fakatamaki fakaenatulá, me te rerenga. I raro i te riri o te riroraa te oraraa o momo i roto i ngā wāhi takutai me motu.

I roto i te 1997, tangohia te UN te Kawa Kyoto, hoahoa nei ki te whakahaere i te nui o pira i te rohe o ia āhua. Taiao whakapono e kore e tino whakaoti reira te raruraru o te warming ao ko kua angitu, engari tino faaiti i te tukanga haere tonu, ko te taea.

tikanga fakangatangata

Ka taea te heke tukunga haurehu kati mā te whai i te torutoru ture:

• whakakore i te whakamahi hauarea o te mana hiko;
• ake i te tōtika o ngā rauemi māori;
• ake i te maha o ngahere, i roto i te wa ki te ārai i ahi ngahere;
• whakamahi o ngā hangarau taiao i roto i te te hanga;
• ki te whakauru i te whakamahi o ngā mātāpuna pūngao whakahou neuglerodovodorodnyh ranei.

E tukuna haurehu kati kōtuhi i roto i Russia i te hononga ki te whānui whakatupuranga mana, keri me te whanaketanga o te ahumahi.

Ko te mahi matua o te pūtaiao ko te tenenga me introduction o kora pokekore, te whanaketanga o te huarahi hou ki te tukatuka rauemi ururua. whakahou āta o paerewa production, mana tino o te ao hangarau me te faatura ia ki te taiao e taea tino whakaiti pira. e kore te warming Global karohia, engari he Nireaha atu ki te whakahaere i te tukanga.
