[Deleting because I don't want to perpetuate apparently debunked climate change myths, sorry, I honestly hadn't seen it debunked.] Dang, my most downvoted comment was asking an honest question about climate change.

Variability in the sun’s output has long been accounted for in climate modeling.

If you aren’t a denier then why are you repeating a classic, thoroughly debunked denier talking point? https://skepticalscience.com/global-warming-on-mars.htm https://skepticalscience.com/global-warming-on-mars.htm

  Maybe they honestly didn't know? Hell, I didn't even know about global warming on Mars until OPs comment..

    It’s possible, but beyond a certain point it becomes difficult to extend the benefit of the doubt.

  Great write-up, I really appreciate it. Don't worry, I won't ask any more honest questions about climate change ever again.

    I don't mean this in a snarky way at all; if you are interested it is easy enough to educate yourself on the basics. "Read first, question later" is a good approach to this sort of thing, really, as it isn't asking for other peoples effort on the easy stuff.

Mars is a radically different planet and has its own climate. It doesn't have anything to do with the sun getting warmer though, e.g. we can't blame the sun for the Earth warming up just because Mars is also warming up. A few of the key differences off the top of my head: - The polar caps of mars are mostly frozen CO2 ("dry ice"), and also mostly disappear during the summer. You can see timelapse animations showing them shrinking and growing by like 90% each year. Their behavior is radically different from our frozen water ice caps, and have a huge difference in thermal mass too. - Mars has a very thin atmosphere, mostly inactive geology, and no oceans. That means it has very little in the way of thermal buffering - Mars goes through it's own Milankovitch cycles (changes in orbit eccentricity, axial tilt, precession) which means it undergoes it's own warming/cooling cycles just like earth. It happens to be in a warming cycle right now. - Enormous dust storms can take over the planet for months at a time, which obviously has a huge impact on global climate - We have a very short record of observing Mars' climate, so we can't really make long term trend analysis like we can on Earth
