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.
