Asteroid bombardment linked to dinosaur extinction theory
Dr Frank Cachille of Pennsylvania State University proposes that random asteroid impacts over 500 million years could disrupt climate by dust clouds and axis shifts. He argues large meteorite events may explain repeated climatic changes and may have contributed to dinosaur extinction by drastic cooling and altered ocean and atmospheric circulation.
