Lucas, Selena, New Mexico Museum discussed on Science Friday

Automatic TRANSCRIPT

Says she is very aware of the parallel. We are always concerned about what's going to happen in the future with modern rapid climate change that experiment has already been run in the past. And so we just have to go back into the past in look at it and evaluated and understand it another parallel disappearing species the causes and the players may be different. But the outcome could be the same. Some paleontologists have even started to call. Our current diversity crisis the sixth mass extinction. I think it's fair to call it a sixty six six should that hasn't played itself out Spencer, Lucas is a paleontologist at the New Mexico museum. Natural history. He's known in the field for being skeptical that the big five extinctions with a blockbuster wipeouts. They're made out to be even so he's not shy about putting a label on the climate change. We see today will scary about it to me as it's happening really fast. You know, this is an extinction. That's only happening so far on the scale of perhaps a few hundred years or less, Selena on the other hand isn't willing to go. That far yet are timeframe for defining mass extinction is on the order of thousands of years. So we have to be careful. However, the geology part of me that understands the long-term carbon cycle sees this as a major major event if you check back with me in a in a hundred thousand years or a million years I'd say probably we'll see this as a mass extinction. So who will be the winners and the losers of this mass extinction. If indeed we are going through one right now, the fighter sores are gone. So are all the non avian dinosaurs..
