Colloquium - Topic - Impact

Topic: Impact

Presenter - Prof Don Kurtz (FNAS)
Abstract
66 million years ago the Cretaceous came to an end with the impact of a 10-km diameter asteroid. The explosion, tsunami, fires, smoke, dust and vapour ejected into the atmosphere all led to a long global winter that killed 75% of all living species, including the iconic dominant dinosaurs. The birds made it through, as did our small mammal ancestors, and here we are. But there are other asteroids that cross the Earth’s orbit. The Earth is hit by smaller ones regularly, and inevitably someday another big one will hit. Unless we can deflect it. Can we stop the next extinction level event? Come hear the story.
