Sun May Be Warming Both Earth and Mars 1050

Posted by Zonk

MCraigW writes "Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes might have a natural — and not a human-induced — cause. Mars, it appears, has also been experiencing milder temperatures in recent years. 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."

      Great! If we can blame the sun and not human activity then we don't have to do anything about it! Sort of like if a flood is caused by a storm and not by a dam breaking then we don't have to try to swim. Ummm, wait a minute...

    I am more worried about carcinogenic crap in the ground, in the water and in the air than global warming.
    Under the guise of "global warming isn't real" .. the global cancer rate is going to go up.

    Thanks a lot.

    We need clean nuclear power ASAP charging our electric cars, not driving around cancer fumers.

      It causes cancer, after all. But it is only 10-40% of recent temperature increases according to the people who spend their professional careers on such questions. Things can have more than one cause.

      The good news is that this is one of the issues where you don't have to understand ocean circulation, feedback loops, or satellite calibration. Just look at what's warming up and what isn't. From CO2, you get heat retained at low altitude that would otherwise be radiated into space. Expected result: nights warmi

    Global warming is such a politicized issue from both sides, and a lot of money from both environmentalists and big oil is going into 'proving' it, that it's really quite difficult to know what is happening at all. This is in addition to the natural difficulties of the subject, who can say for sure what is happening in such a big place as the earth? Sure we have the satellites measuring temperature, but we know they had errors once, how do we know they are not in error still? Anyone who says they 'know' global warming is/isn't reality ought to be treated with suspicion.

    That said, taking care of the environment in general is a good thing. So either way we ought to research renewable energy, keep recycling, etc.

      Suppose for the sake of argument that it is natural. If it creates havoc for humans, such as bad weather, lost farmland, and lost coastlines, then perhaps we should still do something about it. Continuing to pump CO2 into the atmosphere is not helping the situation.

        How much CO2 is human activity producing? What is that, as a percentage of total CO2 being produced from all natural and artificial sources? Of all the greenhouse gases being produced, what percentage is CO2?

    "And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report."....

    Perhaps the biggest stumbling block in Abdussamatov's theory is his dismissal of the greenhouse effect, in which atmospheric gases such as carbon dioxide help keep heat trapped near the planet's surface.

    He claims that carbon dioxide has only a small influence on Earth's climate and virtually no influence on Mars.

    But "without the greenhouse effect there would be very little, if any, life on Earth, since our planet would pretty much be a big ball of ice," said Evan, of the University of Wisconsin.

    It is common knowledge that the sun goes through cycles in which its output is increased thereby increasing the the solar radiation that strikes its planets. However we are still putting greenhouse gasses into the atmosphere which act to trap the solar radiation on the Earth. No reputable scientist will claim that every fraction of a degree in temperature increase is due to human influence on our atmosphere but they do know that the methane and carbon dioxide that we put continually pump into the atmosphere acts as a solar trap and can't help but raise the overall temperature of the planet.

    As usual, some useful discussion of these issues can be found on RealClimate.org. The following two articles are worth a look, though neither is especially recent:

    The punchline from the latter article is, "There is a slight irony in people rushing to claim that the glacier changes on Mars are a sure sign of global warming, while not being swayed by the much more persuasive analogous phenomena here on Earth..."

    It's sad when contributors pick and choose only the parts of an article that support their own viewpoint and hope that readers are unwilling to read the whole article. Anyone who has RTFA can see that fully half of the article is a repudiation of this man's hypothesis by most of the scientific community:

    Choice quotes

    "His views are completely at odds with the mainstream scientific opinion," said Colin Wilson, a planetary physicist at England's Oxford University. "And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report."

    Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that "the idea just isn't supported by the theory or by the observations."

    Perhaps the biggest stumbling block in Abdussamatov's theory is his dismissal of the greenhouse effect, in which atmospheric gases such as carbon dioxide help keep heat trapped near the planet's surface.

    To add to this, I'd like to point out that global warming deniers are quick to dismiss 650,000 years of data about earth's temperature as not being representative of the facts, but they jump on 3 years of data (and data confined to a local area and not the whole planet) as evidence against global warming, solely because they think it supports their opinion. If they were serious about science, they would apply the same rigour to the arguments they agree with as to the arguments they disagree with.

    Searching through for his previous works [google.com] he has never published anything on climatology. This would be make his speculations well outside his field of study. Now, being a physicist myself I know that knowing physics gives you better understanding many other things. But, his one article doesn't get precedence over the mounds and mounds of other published work by people in the fields of climatology, environmental sciences, atmospheric sciences, etc. who are considered experts and are well published. If anything he might just be mentioning global warming to get money, as some /.'ers assumed about the deep sea temperature oddities article a while ago. Both sides can do it you know :). Patrik
