Dinosaurs' Gaseous Emissions Warmed Earth?

Giant sauropods produced huge amounts of greenhouse gases, study suggests.

Dinosaurs may have helped warm ancient Earth via their own natural gaseous emissions, a new study says.

Like modern-day ruminants, giant plant-eating dinosaurs likely had microbes in their guts that gave off large amounts of methane—a potent greenhouse gas even more effective at trapping heat than carbon dioxide. (Read about the greenhouse gas effect.)
