Belching moose add to global warming

OSLO (AFP) - A grown moose belches out methane gas equivalent to 2,100 kilograms (4,630 pounds) of carbon dioxide a year, contributing to global warming, Norwegian researchers said Wednesday. That is more than twice the amount of CO2 emitted on a round-trip flight across the Atlantic Ocean from Oslo to the Chilean capital Santiago, according to Scandinavian Airlines. "An adult moose emits about 100 kilograms of methane gas a year. But methane gas is much stronger than carbon dioxide, so to get the equivalent you have to multiply by 21," professor Odd Harstad at the Norwegian University of Life Sciences told AFP. Read more here.
