The asteroid that killed the dinosaurs sent Earth into multi-year winter

  • 7 years ago
It is generally accepted that roughly 66 million years ago the Chicxulub asteroid killed off the dinosaurs. New information seems to support that theory, as scientists have now found that following the impact of the asteroid, the Earth experienced an extended winter. For several years, the Earth likely averaged temperatures below freezing, with ocean temperatures being impacted for hundreds of years.
