Climate Engineering As US Policy? 355

EricTheGreen writes "The Associated Press has an article featuring Obama administration science advisor John Holdren discussing potential climate engineering responses to global warming. Among the possible approaches? His own version of Operation Dark Storm — shooting micro-particulate pollution high into the atmosphere to reflect the sun's rays. I'm sure the rest of the world would have no issue with that at all, of course. Yikes ..."

    Reflecting more sun from the top of the atmosphere while increasing greenhouse gasses will place us in yet another unknown region of the earths dynamics.

    It might work in controlling temperature - for some small part of the earth - if you get it right, but this is a multi variable system, people might not like your attempts to control temperature if rainfall patterns are altered, winds and currents change, and we get less sunlight to run solar and wind power and grow crops.

    Slightly-nutty (but carefully analytical) Libertarian magazines were bandying these ideas around in 1997 [reason.com], and they'd already been around a while by then. I'm a big fan of the "paint it white" approach - increase the urban albedo by using concrete instead of asphalt, using light-colored roofs and paints... Not only does it reflect sunlight (cooling the earth) it also reduces the "heat island" effect so you don't need as much air conditioning in the summer.

    The real problem with any such approach, they argue, is

    Having sinned against Mother Nature inadvertently, many are keenly reluctant to intervene knowingly. Sherwood Rowland, a chemist at the University of California at Irvine who predicted, with Mario Molina, the depletion of the ozone layer, declared, "I am unalterably opposed to global mitigation." This added considerable weight to the abstention cause. At root, such people see mankind as the problem; only by behaving humbly, living lightly upon our Earth, can we atone.

    This religiosity in climate-change politics fascinates me - it's why I like the Michael Crichton essays/speeches on the topic even though he says "climate change is fake!" and it's pretty much Not Fake. More recently, I've seen stuff in that same Libertarian magazine [reason.com] comparing the current climate-change political scene to "denigrating HIV treatment and blocking condom distribution in order to discourage promiscuity.

    Most of these Dire Global Warming predictions are based on computer models which are known to be flawed.

    Any measure taken to counteract perceived Global Warming must be reversible if found ineffective (or worse, a hindrance). Injecting more particulate pollution into the atmosphere to counteract Global Warming doesn't sound to me like an easily reversible thing. Far safer and easier to do, me thinks, to park a large asteroid in synchronous orbit between the Earth and Sun to occlude solar radiation. If it's "too effective" then it can be (comparatively) easily moved or removed, if it's "not enough" then more can be gathered.

    Here's a simple solution I haven't heard anyone propose. Extensive renewable thinning of the forests.

    Forests only absorb co2 as they grow, once they reach maximum density they become carbon neutral. When a forest reaches maximum density all carbon absorbed by new trees is offset by the trees that died and provided the room. But by continually thinning out our forests and allowing them to regrow we'd gain a infinitely renewable supply of zero net carbon fuel in the form of the harvested wood.

    The wood produced could be used to generate electricity, or could be even chemically converted directly to combustible fuel. In addition, the wood could be used for cheap carbon negative building material.

    The infrastructure for this would be cheap, the technologies available, and most importantly, it would be immediately profitable. I'm not surprised this hasn't been seriously considered though, both sides in this controversy seam more interested in using it for political leverage than approaching the problem with any sense of logic.
