E dechara akụkọ nnyocha mbụ (FAR) nke Intergovernmental Panel on Climate Change (IPCC) n'afọ 1990. Ọ rụrụ ọrụ dị ka ihe ndabere nke United Nations Framework Convention on Climate Change (UNFCCC). Akụkọ a nwere mmetụta ọ bụghị naanị na nguzobe nke UNFCCC, kamakwa na nzukọ mbụ nke òtù (COP), nke emere na Berlin na 1995.[1] Nchịkọta nke WG I Summary for Policymakers na-akọ na ha kwenyesiri ike na ikuku sitere na ọrụ mmadụ na-abawanye oke ikuku nke gas na-ekpo ọkụ, na-akpata na nkezi okpomọkụ ọzọ nke elu ụwa. Ha ji obi ike gbakọọ na CO2 bụ ihe kpatara ihe karịrị ọkara nke mmetụta okpomọkụ.
Ha buru amụma na n'okpuru ọnọdụ "azụmahịa dị ka ọ na-adị" (BAU), ọnọdụ okpomọkụ zuru ụwa ọnụ ga-abawanye ihe dịka 0.3 Celsius C kwa afọ n'ime narị afọ [21st]. Ha kpebiri na ọ̀tụ̀tụ̀ okpomọkụ ikuku dị n'elu ụwa amụbaala site na 0.3 ruo 0.6 °C n'ime 100 afọ gara aga, na-ekwekọ n'ụzọ sara mbara na amụma nke ụdị ihu igwe, mana ọ dịkwa otu nha dị ka mgbanwe ihu igwe eke. Nchọpụta na-enweghị mgbagha nke mmetụta griin haus emelitere agaghị enwe ike ruo afọ iri ma ọ bụ karịa.
Akụkọ mgbakwunye nke afọ 1992 bụ mmelite, nke a rịọrọ n'ihe gbasara mkparịta ụka UNFCCC na Earth Summit (United Nations Conference on Environment and Development) na Rio de Janeiro na 1992. Nkwubi okwu bụ na nyocha kemgbe 1990 "emetụtaghị nghọta anyị banyere sayensị nke mmetụta okpomọkụ ma ọ bụ kwado ma ọ bụ ghara ịkwado mgbanwe nke nkwubi okwu ndị dị mkpa nke nyocha sayensị IPCC mbụ". O kwuru na simulations na-agafe agafe (nke na-adabere n'oge), nke bụ nke mbụ na FAR, emelitere ugbu a, mana anaghị agụnye mgbanwe aerosol ma ọ bụ ozone.

Nchịkọta ndị isi nke nchịkọta ndị na-eme iwu nke akụkọ WG I gụnyere:
- Anyị ji n'aka ihe ndị a: enwere mmetụta okike na-ekpo ọkụ...; ikuku sitere na ọrụ mmadụ na-eme ka ikuku nke gas na-ekwo ọkụ na-abawanye: CO2, methane, CFCs na nitrous oxide. Mmụba ndị a ga-eme ka mmetụta okpomọkụ dịkwuo elu, na-akpata na nkezi okpomọkụ ọzọ nke elu ụwa. Gas na-ekpo ọkụ, mmiri na-ekpuchi, ga-abawanye na nzaghachi maka okpomọkụ ụwa ma mee ka ọ dịkwuo mma.
- Anyị ji obi ike gbakọọ na:CO2 abụwo ihe kpatara ihe karịrị ọkara nke mmetụta okpomọkụ; gas ndị dị ogologo ga-achọ mbelata ozugbo na ikuku sitere na ọrụ mmadụ nke ihe karịrị 60% iji mee ka ọnụ ọgụgụ ha kwụsie ike na ọkwa taa.

- Ikpe anyị bụ na: okpomọkụ ikuku zuru ụwa ọnụ ejirila 0.3 ruo 0.6 °C rịa elu n'ime afọ 100 gara aga..; Ọnụ ọgụgụ nke okpomọkụ a kwekọrọ n'ozuzu ya na amụma nke ụdị ihu igwe, mana ọ bụkwa otu oke dị ka mgbanwe ihu igwe. N'ihi ya, mmụba a hụrụ nwere ike ịbụ n'ụzọ dị ukwuu n'ihi mgbanwe okike a; n'aka nke ọzọ, mgbanwe a na ihe ndị ọzọ sitere n'aka mmadụ nwere ike belata okpomọkụ ka ukwuu nke mmadụ kpatara.

Mmụba e buru n'amụma bụ ihe dị ka 20 cm ... site na 2030, na 65 cm site na njedebe nke narị afọ na-esote.
