mass extinction

In this video, comparisons are drawn between the events that led to the end-Permian extinction and our current trajectory in terms of CO2 release and anthropogenic global warming. The climate system and physics don’t care about the source of CO2. They will just do what they do and we will have our consequences. It is easy for deniers to dismiss this sort of video as “alarmist” but the onus is on them to explain why the possible outcomes won’t happen without resorting to magical or wishful thinking. Good luck with that.
