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
