Dinosaurs survived when CO2 was extremely high. Why can't humans?

How did plants and animals survive around 200 million years ago when the carbon dioxide concentration went up to 6,000 parts per million? Paul Olsen, a geologist and paleontologist at Columbia Climate School's Lamont-Doherty Earth Observatory, walked us through what scientists know about carbon dioxide levels over time.

Although no one was around to measure the atmosphere's CO2 concentration millions of years ago, paleoclimatologists can reconstruct past temperature and carbon dioxide levels using ice cores, tree rings, corals, ancient pollen, and sedimentary rocks. These natural recorders of climate fluctuations can also reveal how various animals and plants thrived or perished during different geological periods.
