If global warming isn't solar in nature, why is Mars also heating up?

Never mind the planet Mars has heated up almost one degree F in the last few years.

    Giant dust storms, unique to Mars. At least that's what the NASA scientists who measure Mars temperature say:

    We know it's not changes in the Sun, because many people measure the Sun, all the time, and solar radiation has been decreasing a bit for some time:

    climate forcings and the global mean surface

    air temperature", Lockwood and Frolich (2007), Proc. R. Soc. A


    News article at:

    Al Gore has nothing at all to do with the science that proves global warming is real, and mostly caused by us. That's a political argument, not science.

    There are a relatively few "skeptics". There are also "skeptics" (and even a few scientists) who believe the Earth is 6000 years old and that NASA faked the Moon landings. It's all unscientific nonsense.

    The data proves global warming. Admiral Truly has it right:

    "I wasn’t convinced by a person or any interest group—it was the data that got me. I was utterly convinced of this connection between the burning of fossil fuels and climate change. And I was convinced that if we didn’t do something about this, we would be in deep trouble.”

    The implication of this question is that any warming must be caused by an external factor such as an increase in solar radiation. But this isn't the case with the observed changes on Mars.

    Mars does have an atmosphere and consequently both climate and weather, though unlike any we see on Earth. The Martian atmosphere is 100 times less dense than that of Earth and primarily made up of Carbon Dioxide (CO2). Although Mars does have seasons, the temperature only varies from very cold to extremely cold, The surface temperature fluctuates between 100 C (-148 F) to 0 C (32 F). The ‘snow’ on Mars surface is in fact Dry Ice – frozen CO2. The melting point of CO2 is minus 56.6 degrees C. so a small increase in solar radiation should have a major effect on such a cold temperature planet. But given how much Earth has recently warmed (0.65C) producing demonstrable changes, you’d expect even more dramatic results on Mars, as it’s starting from a much lower temperature and is only one & a half times as distant from the Sun as Earth is. And this isn’t the case.

    It’s likely that Mars is just coming out of an ice age, just as Earth did in the past 100,000 years or so. Like Earth, Mars has small fluctuations in its orbital (astronomical) cycle (Rather like the small fluctuations in a spinning gyroscope.) Earth’s fluctuations are known as Milankovitch cycles that alter the distribution and amount of solar energy the planet receives. But these rises and falls in overall temperature are caused by the planet’s tilt and wobble in its rotation as well as eccentricities in its orbit, not because of any increase/decrease in solar radiation.

    If all of the carbon dioxide that is being released into the Martian atmosphere from the south polar cap is not freezing out somewhere else, and if it is not being adsorbed into the Martian soil, then it must be causing the atmospheric pressure to increase. As carbon dioxide is a ‘greenhouse gas’ this would cause the global temperature to increase considerably (over 1000’s of years) and make it easier for liquid water to persist elsewhere on the planet.

    Any planet with an atmosphere - in any solar system - will have its own changes to climate over very long periods of time.

    i havnt heard much on the sbubject, but heres just a guess.

    like earth, mars goes through heating and cooling periods.

    unlikes earth, mars is not producing mass amounts of green house gasses like earth is. though they might be heating up, earth is at a much faster pace.

    note- this is a hypothosis, and you should do some mroer reasearch. god question though
