I was simply trying to illustrate -- assume we didn't know about earths tilt; one would suspect something like the moon or stars causes the seasons (as they did historically).

IMO as we don't have accurate data measuring far enough back we're effectively shooting in the dark.

It's fine to say, these two things could be correlated, it's another to say these things are correlated AND to fix it we have to force everyone to stop traveling, be less healthy (eating a worse diet), etc.
