T-Rex: Oh boo hoo the climate is changing. Well guess what, nerds? The climate changes all the time!!
T-Rex: Or have we forgotten a little time period called 2.3 BILLION YEARS AGO??
T-Rex: Cyanobacteria showed up then and ate water and pooped out oxygen. And you know what happened? The atmosphere changed from basically 0% oxygen to 20% oxygen and HEY PRESTO, life exploded.
Dromiceiomimus: You're really arguing this?
T-Rex: I'M REALLY ARGUING THIS, yes.
Utahraptor: Well you know that this Great Oxygenation Event killed lots of life?
T-Rex: Can't make an omelet without breaking a few eggs!
Utahraptor: It was one of the most significant extinction events in our planet's history. Sure, we oxygen breathers got a sweet deal out of it, but all those anaerobic organisms that lived here before? DIDN'T WORK OUT SO WELL FOR THEM.
T-Rex: So new CO2 breathing life shows up and enjoys the heck out of it! We had a good run, nerds!!
T-Rex: NERRRRRRDS
