Harvard Scientists Say It's Time To Start Thinking About Engineering the Climate

merbs writes: Harvard has long been home to one of the fiercest advocates for climate engineering. This week, Harvard's School of Engineering and Applied Sciences published a research announcement headlined "Adjusting Earth's Thermostat, With Caution." That might read as oxymoronic — intentionally altering the planet's climate has rarely been considered a cautious enterprise — but it fairly accurately reflects the thrust of several new studies published by the Royal Society, all focused on exploring the controversial field of geoengineering.

    We've been doing unintentional geoengineering for hundreds of years now, why would some intentional geoengineering be so bad?

      This -- which is the longest and most comprehensive study to date -- says there is no detectable warming in the deep ocean.

      So I don't know who you've been listening to, but my sources say it isn't happening to any noticeable degree.

      No, that source concludes: "The net warming of the ocean implies an energy imbalance for the Earth of 0.64 +/- 0.44 W/m^2 from 2005 to 2013."

      Well, an Earth sun-shade would need to block at most a few % of the sunshine falling on the Earh, while for Venus (if we want to cool the planet off this millennium) we will need to block all of the Sun's rays for a while, so the engineering is a bit more difficult. Add to this the detail that the Venus Lagrange point 1 is quite a bit further away than the Earth's, and energetically harder to reach, and I think a more reasonable conclusion is that the Earth would be training wheels for Venus, and not vice versa.

    Sure. Let's engineer it. Just tell me what the optimum global mean temperature is, and I'll get right on it.

  4. How about engineering the economy? by bigsexyjoe · · Score: 4, Insightful

    I think the idea that we are going to engineer the environment is crazy and dangerous. The fact is we don't HAVE to keep dumping CO2 into the air. We can dramatically shift our priorities and resources to finding alternative energy.

    Granted, the economic incentives for clean energy aren't there right now, but is capitalism a suicide pact?

  7. Sun shade by mbone · · Score: 3, Insightful

    I am convinced we will eventually build a sunshade, out at the first (inner) Earth-Sun Lagrange point. It won't help with ocean acidification, but it would make a global thermostat possible.

    And, it will be good practice on fixing Venus.

  8. Re:Global warming is bunk anyway. by dnavid · · Score: 5, Interesting

    We shouldn't be fooling around like this. It's obvious we don't understand, or are too corrupt and greedy to admit, that there's no problem.

    Its ironic that one of the potential benefits of geoengineering research is that it will force many climate change deniers to admit that its possible for human activity to have major deleterious effects on Earth's climate.

  9. Re:Global warming is bunk anyway. by duck_rifted · · Score: 3, Insightful

    I don't care for online climate change deniers.

    You use the word "facts". Let's talk about facts. Suppose I tried to debate this nutjob.

    First of all, this person already decided what they "believe," and everything they read will be twisted into evidence supporting their predetermined conclusion. Therefore, right off the bat, actual debate is impossible. They've already decided what they think is true.

    So, we'd go back and forth. They would post evidence supporting their perspective, and off to Google I'd go to dig up rebuttals from actual climatologists. That will take time because the climate change denial groups are always generating new bunk data, new misinterpretations of published papers, and new misrepresentations of past quotes. One can't just keep a database of counterevidence because they've always got new bullshit.

    After however much time I'd spend researching rebuttals, that person would just keep replying with more bullshit. They either wouldn't read the counterpoints or wouldn't understand them. Then they'd pull out the ever-present Final Tactic by telling me that they know what they're talking about because they're a pilot, physics student, congressional aide, or whatever. They'll try to follow up bunk "science" with anecdote.

    By the time the whole thing concluded, I will have failed to convince them because it was never a possibility to begin with. They will have failed to convince me because I actually look at the science and don't delude myself. Then, out there somewhere at their keyboard will sit some layperson who just wants to get along with their church group, some paid anti-climate change shill, or just an everyday idiot repeating what they've been told.

    So.
    1. They won't convince anybody.
    2. Nobody can convince them.

    Therefore, their bringing the subject up to start with is masturbatory and annoying. It accomplishes nothing that walking into a movie theater and announcing over a megaphone that the world is flat wouldn't accomplish.

    The most constructive response is thus, "God damnit, can you just stop this already?" Optionally, this may be peppered with, "Please just go away."
