Reply to comment by mit_catastrophe in We are MIT scientists studying past global environmental catastrophes (mass extinctions, etc.) and their relevance to modern-day climate change. Ask us anything! by mit_catastrophe

How false is the assertion that this climate change is not man-made (or at least not man-catalyzed), e.g. when some say that it's a cyclical change that would have happened anyway?

Whats the cyvle? Can you Show another time this happened? If not, how can it be cyclical?

The earth goes through periods of warming and cooling as (from what I remember) the ellipses of our orbit changes over time.

This is why we have ice ages and stuff.

Take this with a pinch of salt though because this is a 15 year old memory.

So, did you check on the cycles dates? Last time I checked we should come out of an ice age. There is also a cycle which flips the orientation of our magnetic poles or something like that. Maybe you can include that to make an argument for "non man made climate change"

The climate changes naturally. But that’s an entirely different process happening at an entirely different speed to man made climate change.
