Global warming believers are officially grasping at straws. They've headed back to the age of the dinosaur and think the gigantic creatures may have committed suicide by warming up the atmosphere.
Dinosaurs may be partly to blame for a change in climate because they created so much flatulence, according to leading scientists.
Professor Graeme Ruxton of St Andrews University, Scotland, said the giant animals spent 150 years emitting the potent global warming gas, methane. Large plant-eating sauropods would have been the main culprits because of the huge amounts of greenery they consumed.
The team calculated the animals would have collectively produced more than 520m tons of methane a year - more than all today's modern sources put together.
It is thought these huge amounts could easily have been enough to warm the planet. It is even possible that the climate change was so catastrophic that it caused the dinosaurs eventual demise.
