Thread: What would happen if the Chicxulub impact event happened today?

What would happen to Earth's cities/humanity? What would die?
Why would we have to move to space? Why not live and breed in bunkers until the atmosphere clears up?

The debris would fill the atmosphere covering the globe. It would block out the sun and reduce photo synthesis. Many plants would go extinct followed my almost all large animals. The world would have to start over as it did 65 million years ago.

Humanity would have to move its communities to space or it will die.

Getting our collective nickers in a knot would be the least of our problems.

Global fires for around ten years and loss of food besides the canned stuff, would mean that all humanity aside from a few thousand Eskimos near the North Pole would die!

most people and large animals would die from various environmental effects over a three month period. very few people would survive. society as a whole would be gone forever.

While it would be a great disaster and many people would die, it would not be the end of humanity. Our tiny primate ancestors survived Chicxulub, and they didn't have any of the resources that we have today. The main cause of death would probably be famine, since agriculture would be wiped out for a few years due to lack of sunlight. We would have to live on stored food, and there simply isn't enough food stored to feed 7 billion people for three years.
