British scientists have calculated the methane output of sauropods, including the species known as Brontosaurus.
By scaling up the digestive wind of cows, they estimate that the population of dinosaurs - as a whole - produced 520 million tonnes of gas annually.
Yeah! We shall go with this being the silliest article of the year! Where do you think the dinos got all that vegetation in the first place? From things being very warm, wet and full of CO2. As I've said before, the best greenhouse gas is water vapour, which dominates the others by orders of magnitude. Ask the Amazon basin! The dinosaur era was initiated by having all the continents jammed together, and ended when the land masses all left the party.
