Interesting fact of the day: After the asteroid impact that led to the extinction of the dinosaurs it took 32,000 years after the event for the dinosaurs to go extinct.
The climate change itself that resulted took about 4,000 years to fully take effect.
People often say how Climate Change might be a natural process but people don't realize how absurd that is and why scientists laugh at the very idea. Even unnatural climate change like the asteroid that killed the dinosaurs is much MUCH slower than the climate change we are witnessing today. Literally there has never been a point in the history of life on earth where global temperatures have changed as quickly as they are changing now.
