  And destroyed the Baltimore bridge because their backup engines were split between legal fuel and international+waters fuel.

    What’s with the math in the middle of your comment?

      hyphen became a plus? Dalí didn’t have a spare engine because their working spare engine wasn’t purged of fuel that wouldn’t be legal to burn in US coastal waters.

        It was that in combination with the “engine-generators” yes. Made it unclear.

  this is arguably fine, because this way ships make clouds of sulfate aerosols, which have slight cooling effect and no one is bothered by it when it’s released over sea

    It’s only fine until those sulfates react with water vapor in the atmosphere to form sulphuric acid. That stuff rains back down and contributes to ocean acidification which is causing serious harm to all sorts of marine ecosystems.

    Good thing humans are the only life on earth.

      Yeah, what a luck, isn’t it?

    This is wrong in some many ways. To add to the already mentioned. Ocean water is the largest carbon dioxide buffer by absorbing CO2 to become carbonic acid. As the sulfur acidifies the Ocean, this “competes” with the carbonic acid, increasing the CO2 emissions from the Ocean.

    In other words, all geoengineering tropes end up being horseshit.

      I swear every time I see an argument like that one, if they zoomed out and considered a system in total instead of one process they would see that it’s bullshit

      Either they are naive or arguing in bad faith…

    Also, the cooling effect sulphate aerosols can cause only really happens at high altitudes. At low altitudes the reflected light is less likely to escape to space, and the aerosols fall out of the air faster.

    Even if they reached high altitudes, one of the effects of being in the atmosphere is moving with the wind, across entire hemispheres. And at tropospheric heights, sulphates, their products, and other byproducts of combustion may destroy ozone at significant levels.

    There may come a day where aerosol-based geo-engineering becomes a part of climate management, but it’s definitely not with bunker fumes.
