Hmm… maybe, just maybe; the sun has something to do with it? Maybe some kind of radiation or something? Possibly something we don’t know about yet?
Nah! Likely cause is humans. If we hadn’t have landed our robots on Mars, nothing would be different on that planet, ever. Once again, the human scourge is destroying worlds.
And from what I know, the ozone layer has been completely decimated from Mars’ atmosphere!

Absolutely. There have been thousands of climate changes on earth, non of them were man-made. Google the Milankovic Cycles. Very interesting!
