Global Warming…..On Mars

The National Geographic reports on evidence of warming on Mars, which suggests that there may be a non-human cause to similar events on Earth:

Simultaneous warming on Earth and Mars suggests that our planet’s recent climate changes have a natural—and not a human- induced—cause, according to one scientist’s controversial theory.

Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.

Mars, too, appears to be enjoying more mild and balmy temperatures.

In 2005 data from NASA’s Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide “ice caps” near Mars’s south pole had been diminishing for three summers in a row.

Habibullo Abdussamatov, head of the St. Petersburg’s Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.

“The long-term increase in solar irradiance is heating both Earth and Mars,” he said.

Or maybe it’s just because of all the SUV’s  those selfish Martians are driving.

    The Scientist that decided this is simply an idiot. How cann he not see that a major part if not all of global warming is due to the cause of humans and the emissions of greenhouse gases.

    I guess the billions of tons of garbage is not produced by humans either. We have absolutely no impact on our planet.

    I do wish the nay sayers would stop mentioning SUV’s. There are several other green house gases, some that might be caused by changing flora. There are other sources of Carbon Dioxide, besides SUV’s. It soulds like many have read the same junk science theory of global warming.

    One of the things that is irritating me about this whole debate is the arguments over who is at “fault” for global climate changes.

    1) The “damage” being done by any change is dependent on the change itself and not on what caused the change. If a volcanic eruption fills the air with CO2, it will have much the same effect as if we fill the air with CO2. The CO2 does not change its chemical properties depending on whether it came out of a volcano or a chimney stack.

    2) Even if human beings are changing the climate, they are not being evil. The internal combustion engine is responsible for extending human life expectancy manifold, for easing our lives, for our reduced vulnerability to natural disasters. People who would 100 years ago lived painful short lives of back-breaking labor now enjoy longer, more comfortable lives with luxuries unavailable to the richest man 100 years ago.

    3) Climate change is not due to one cause. It isn’t “all natural” or “man made”. The Earth’s temperature is affected by thousands of variables, solar output, the sun’s position in the galaxy, the Earth’s orbit, the moon’s orbit, the chemical composition of the atmosphere, the composition of the surface, the amount of solar activity etc. Some inputs maybe tending towards increasing the atmospheric temperature, some may be trending towards decreasing it.

    I am very bothered by the claims of many that global warming equates to a need for massive governmental intervention in people’s peaceful affairs.

    People will adapt. Increasing central control of the economy will make it less adaptive, which is a really bad idea if you truly don’t know what the future holds.

    A quick search for solar irradiance charts doesn’t provide back-up for the scientists’s statements. Maybe I’m misunderstandign his argument.

    ‘tarran’ pretty much hit the nail on the head.


    Individuals need to be responsible for themselves and their own environmental footprint. Note that I said “environmental footprint” and not “carbon footprint”. Anthropological Global Warming is an idea with a shaky foundation at best, and utterly indefensible at worst.

    I will still make efforts to be environmentally conscientious, such as using compact flourescents and driving economical vehicles. That’s just a responsible thing to do, and benefits everyone in the long run for a variety of reasons (not Global Warming).

    As for Global Warming itself, there are WAY too many different environmental factors (including effects from space) that play into mean global surface temperature. And we don’t even have a consistent way to measure temperature, as the effect of city growth on ground temp readings has rendered those practically unusable, thermometer accuracy has changed with the advancement of technology over time, and upper-atmosphere or space-based temperature readings have only been available for a geologically insignificant period of time (remember that the geological timescale is hundreds, thousands, or perhaps even millions of years).

    Panic based on media hype isn’t going to help anyone, environmentally or economically.
