Climate inertia
Nguzogide nke ihu igwe bụ ihe omume nke usoro ihu igwe na-egosi nguzogide ma ọ bụ nwayọ na mgbanwe na ihe ndị dị mkpa, dị ka ọkwa gas na-ekpo ọkụ. N'ihe gbasara mgbanwe ihu igwe, nke a pụtara na atụmatụ mgbochi, dị ka nkwụsi ike nke ikuku na-ekpo ọkụ, nwere ike igosi mmeghachi omume dị nwayọ n'ihi ọrụ nke usoro nzaghachi dị mgbagwoju anya. Dị ka ihe atụ a kapịrị ọnụ, ice na-agbaze na Greenland na Antarctica na-ewe oge iji meghachi omume na ikuku carbon na usoro ihu igwe.[1] Okpomọkụ ụwa na-akpatakwa inertia okpomọkụ, mgbasawanye okpomọkụ nke oké osimiri, nke na-enye aka n'ịbawanye oke osimiri, a na-eme atụmatụ na anyị etinyelarị aka na ịrị elu oke osimiri nke ihe dịka mita 2.3 maka ogo okpomọkụ ọ bụla n'ime afọ 2,000 sochirinụ.[2]
Nguzogide nke okpomọkụ

A na-akọwa ya na ụdị ihu igwe zuru ụwa ọnụ, a kwadoro ya site na nyocha nke nguzozi ike nke ụwa.[1] Permafrost na-ewe ogologo oge iji meghachi omume na mbara ala na-ekpo ọkụ n'ihi nguzogide okpomọkụ, n'ihi ihe ndị jupụtara na ice na ọkpụrụkpụ permafrost.[3]
Mmetụta ihu igwe na-agafe agafe na mmetụta ihu igwe na nguzozi kwekọrọ na oge inertial thermal. N'ihi ya, mmetụta ihu igwe nke ụwa na-agbanwe ka oge na-aga ruo mgbe e ruru nguzozi ọhụrụ.
