Dust kicked up by asteroid impact killed off dinosaurs

A recent study published in Nature Geoscience has revealed that fine silicate dust played a significant role in the global cooling that occurred after the asteroid impact that led to the extinction of nonavian dinosaurs. The dust, which lingered in the atmosphere for up to 15 years, caused a long and dark winter, interrupting photosynthetic activity on Earth. The research provides valuable insights into the post-impact period and helps to understand the impact on the dinosaur population.
