Scientists Propose Solar Geoengineering to Combat Climate Change

Troubling? By creating “low-altitude marine clouds” and “increasing the concentration of aerosols in the atmosphere”…

Solar geoengineering, the goal of which is to offset the global warming caused by greenhouse gases, involves reflecting sunlight back into space. By increasing the concentrations of aerosols in the stratosphere or by creating low-altitude marine clouds, the as-yet hypothetical solar geoengineering projects would scatter incoming solar heat away from the Earth’s surface.

Critics of geoengineering have long warned that such a global intervention would have unequal effects around the world and could result in unforeseen consequences. They argue that the potential gains may not be worth the risk.

“Our research goes a step beyond the one-size-fits-all approach to explore how careful tailoring of solar geoengineering can reduce possible inequalities and risks,” says co-author David Keith, Gordon McKay Professor of Applied Physics at the Harvard School of Engineering and Applied Sciences (SEAS) and Professor of Public Policy at Harvard Kennedy School. “Instead, we can be thoughtful about various tradeoffs to achieve more selective results, such as the trade-off between minimizing global climate changes and minimizing residual changes at the worst-off location.”

    I love to watch monkey’s try to tweak Nature
    the results are always dangerously amusing

      I remember that as a child I was obsessed with fireworks. Though I loved
      them so, I could never just let them be fireworks. I always wanted to
      do something really dumb and dangerous. For instance, what happens when you put the bottle rocket down in the bottle? (Spoiler Alert: a lot of cleaning glass up off the street.) Co-incidentally it was also a
      lot of fun.

      These guys seem hopped up on that same high. It’s not healthy. Let’s hope its fun?

    Psychopathic scientists playing god. The Arctic sea ice is not in danger. http://www.youtube.com/watch?v=mEfJO0-cTis

      So you’re saying no countries or companies are racing or vying to drill for oil in areas opened up by less winter ice?

        Nope, wasn’t saying that at all. A slight enhancement of a trace gas (.035% of the atmosphere) will not create “The Day After Tomorrow anytime soon.”

          And by soon I mean ever. Now Asteroids, Comets and particulate matter laden ionospheres cooked in Satan’s microwave (HAARP) might do the trick, hence the flick I linked.

    The term for this is “manufacturing consent, retroactively”

    ok. wait a minute. “the as-yet hypothetical solar geoengineering projects would scatter incoming solar heat away from the Earth’s surface.”? are they seriously trying to suggest that this hasn’t been going on for over 15 years? as-yet hypothetical my ass!!! geoengineering doesn’t scatter incoming solar heat. it traps the heat underneath. it does however scatter incoming solar light… (look up global dimming.)

      oh… and for those of you still with a working mind, you may want to take a look a this -> “owning the weather by 2025″ http://csat.au.af.mil/2025/volume3/vol3ch15.pdf

      I’d not be surprised if Monsanto had a part in this. They are selling aluminum resistant “terminator” seeds which produce fruits and veggies that don’t generate more seeds. This would only make sure they had no competition.

    BS solution to a non existent problem. Well done guys.

    Polluting the skies to combat a myth. If that doesn’t say Orwellian 21st century environmentalism I don’t know what does.

    Corporate Sponsored Scientist 1: “We have a climate change problem in part due to anthropologically created chemical imbalances. How should we proceed?”

    Corporate Sponsored Scientist 2: “Perhaps we can spray the atmosphere with billions of tons of chemicals and alter the weather.”

    Corporate Sponsored Scientist 1: “Brilliant! Initiate the study. And remember: conclusion before data if you want to see our next grant.”
