The asteroid that slammed into Earth and heralded the doom of the dinosaurs triggered a surge in volcanic eruptions that made the catastrophe even worse, researchers claim. Scientists analysed prehistoric lava flows in India and found that soon after the massive impact, volcanic eruptions became twice as intense, throwing out a deadly cocktail of sulphur dioxide and carbon dioxide. The shockwaves produced when the space rock thumped into Earth likely shook up volcanic plumbing systems around the world, creating larger magma chambers that spewed out more material when they erupted. Combined with the hefty impact, the increase in volcanic activity would have pumped enough dust and noxious fumes into the atmosphere to blanket the Earth and drive many species to extinction.

It only makes sense.

Nah, it wasn't the asteroid, it was anthropogenic global warming.
