    Re: Cheap ways to cool the earth

    The Sky is falling!!!!!

    Most of the positive posts here have generally said we should take action to avoid a cateclysmic change in the future. Zero control! We have no defense at all against a global cateclysmic event except to vacate said premises, and we are not even close to ready to do that.

    Fund NASA! Fund NASA!

    Almost everyone has shaded their comments with a hint that human action is not natural; e.g., human intervention. Whatever humans do on this planet or elsewhere in the universe is entirely natural to the environment. We are not aliens in this universe. If we erode the planet or use up its energy resources that depletion is a natural depletion caused by natural organizisms on and of the planet. It's sort of analygous to the depletion of a radioactive isotope.

    Now, that being said and the guilt from intelligent self-awareness being assuaged, let's clean this mess up!

    Re: Cheap ways to cool the earth

    There was an idea years ago to put millions of small "mirrors" in orbit that would reflect the sunlight back into space. If they needed to come back we would just round them up.

    They would be so delicate that they would not harm satellites.

    How about every man woman and child simply holds their breath throughout the day for a maximum of 5 minutes - say, 5 times for 1 minute each. That would save approximately 60 tons of C02 per day being expelled into the atmosphere. Let's have some scientists appy for some billion dollar grants to study this "breath holding" thing for 10 years, and then start a large bueracracy as part of our government to enforce this. Everyone needs to pull their weight for the common good... deep breath now, and hold.... hold........... hold.......

    Why don't you think we can modify the earth's climate? We know for a fact that volcanic eruptions cool the earth, by spraying sulfur dioxide into the atmosphere. We can even measure how much sulfur dioxide they emit and how much it cools the earth. The smokestack idea in the OP is the same concept...it would just be humans doing it instead of volcanoes.

    They also represent massive uncertainty. There is no telling what unintended consequences could result from either of these options. You could potentially make things worse than they already were. You cannot guarantee that it won't.
    This is true, I can't guarantee that. But I *can* guarantee that eliminating all CO2 emissions would make life worse. And scientists can say with a reasonable (though not 100%) level of confidence that these will not.

    The half-life of sulfur dioxide in the stratosphere is about a year. Clouds dissipate within an hour. So no matter how terrible the unintended side effects of these proposals were, they wouldn't be long term problems since the machines could easily be shut off.

    They aren't ideal solutions, but I think they're a lot better than radically altering our economy and standard of living and/or doing nothing if climate change becomes very severe.


    I think that by the middle of this century, it's highly likely we will be able to (and will) control the weather and the climate at all times. This sort of thing seems like the first steps toward that, where the possible solutions are uncertain at first and gradually become safer.

    The smokestack idea in the OP is the same concept...it would just be humans doing it instead of volcanoes. So I'm unclear as to why you don't think it would work.
    A Volcanic eruption is far greater than anything man can concoct; but let me make my point painfully clear about this farce called "man caused" global warming.

    First let's all be clear, the debate is the farcical notion that this is "man caused" not about Global warming. We all know and readily acknowledge that for centuries the earth has been experiencing a warming trend.

    How do we know this? Well for one thing, in the great State of California where we have a fantastic park called Yosemite, the scientists tell us that the massive granite formations we are looking at were formed by massive glaciers that retreated millions of years ago leaving much of what we see today.

    Now someone with a modicum of intellect and intelligence might ask whatever it was that caused the massive melting that caused the glaciers to retreat, not just from the USA, but from the entire country of Canada way back before man was even a major part of this world?

    The TRUTH is that there is believed to have been at least FOUR other major warming and cooling trends long before man was ever evident.

    At least seven ice ages have been recognized. At least four of them are considered significant because of the extent of their glaciation or because they lasted for an extremely long time:

    about 2 million years ago to the present—the Quaternary Ice Age
    350 to 250 million years ago—the Karoo Ice Age
    800 to 600 million years ago—the Cryogenian (or Sturtian-Varangian) Ice Age
    2400 to 2100 million years ago—the Huronian Ice Age.


    The FACT is that this farcical myth being perpetuated by primarily Librul self proclaimed "environmental scientists" and is nothing more than an effort to fear monger people into behavior that will not only result in the economic decline of our economies, but perhaps even the starvation of millions should they get their way. These are the same scam artists that in the 70's gave us the "chicken little" claims of global cooling.

    I am sure these con artists like Al Gore, the dumbest man in America, are passionate in their beliefs; but their science is MORE than suspect.

    The SUN is the single BIGGEST culprit in this cooling and warming and has been expressed by many scientists for decades but conveniently ignored by those attempting to promote this "inconvenient" lie about man caused global warming.

    I would be more afraid of a massive trend in cooling than I am about warming. At least with warming many areas formerly inhospitable in the Northern hemisphere will be more adaptable to crop growth to continue feeding a growing population.

    P.S. it is not just that I don't think that man can modify the earths climate; but also that it would be extremely dangerous to mess with the complex equilibrium that ecompasses this planet. Here's a thought: the water we drink is the same water dinosaurs waded and pissed in.

    Two factories belching sulfur dioxide into the stratosphere - one in the Northern Hemisphere and one in the Southern Hemisphere - would be sufficient to mimic the effect of a large volcanic eruption like Mount Pinatubo.

    And cars were an environmental improvement that eliminated the most prominent pollution problem of the previous era - horses. What kandahar is discussing is the next generation of that idea.

    Seriously, read the book. It's quite interesting.
