Note that the article states that the described events caused mass extinction because of heat-trapping carbon dioxide. So it was really fast global warming. Not sun-obscuring ash and smoke in the atmosphere, causing plants to die from loss of photosynthesis, thereby starving the dinosaurs to death. No, it just got uncomfortably warm for them and they died. From heat exhaustion.
Transsexual racist trans-pseudo-dinosaurs really, really cis-piss me off.
I’m recalling high school and college classes here, but I was under the impression that the world was then very warm, allowing cold-blooded reptiles to dominate and reach tremendous size along with tropical flora, and this all changed to a colder climate that favored warm-blooded mammals, due to an asteroid impact.
When did this change?
