Are we actually responsible for global warming? Or our ancestors? Discovering that the earth suffered a sudden, severe period of global warming approximately 180 million years ago, researchers have helped soften the abysmal debate and pounding guilt for being the cause, among us. They believe that a vast quantity of methane gas was released in three magnanimous pulses. As a consequence underwater stores of gas hydrate melted, heating the Earth by 10 degrees C and erasing out of existence a large number of species on land and in the oceans. It was also the time when the dinosaurs romped the earth surface.
