“I think we’ve discovered something important here. It’s subtle, but it could make a big difference.”
Ash and debris in the atmosphere can make a huge difference to the planet’s temperature.
Following the asteroid collision which wiped out the dinosaurs 66 million years ago, huge amounts of ash and debris were ploughed into the atmosphere, blocking out sunlight for tens of thousands of years.
Previous research from the University of Berkley, California, believes there is evidence to suggest non-avian dinosaurs survived around 30,000 years afterwards, and they eventually went extinct due to the 100,000 years of drastic climate change caused by the impact.
