The Ozone Hole Above Antarctica Has Grown To Three Times the Size of Brazil - Sl...

• • You know the ozone layer crisis was fixed by humans assuming responsibility and changing their behavior, right?

        BTW... Since no one has asked, how many Manhattans is a Brazil?

    • Ah, those were the days! Remember when we could all pull together to solve a problem? Scientists told us ozone was depleting & that we were causing it. Governments responded by getting together to ban the cause of the depletion & required corporations to change to less harmful alternatives. Imagine if we could do that today, e.g. stop granting new oil & gas drilling licences so that we can phase out fossil fuels so that millions (billions?) of people don't starve to death?

      • Governments responded by getting together to ban the cause of the depletion

        Yes, but CFCs were a way way way easier problem to solve than GHGs.

        required corporations to change to less harmful alternatives.

        Yes, this is what made it easy. Manufacturers changed how they made a few products in a way that was mostly invisible to normal people.

        Addressing global warming is nothing like that. Everyone will have to change in very visible ways.

        e.g. stop granting new oil & gas drilling licences

        Uh, no. Joe Biden kissing up to Maduro and fist-bumping MSB was an admission of the folly of a supply-side solution. Cutting off oil production before we have alternatives leaves us at the mercy of our geopolitical adversaries and creates a political backlash from the denialists.

        We need EVs, more lithium production, more copper, more cobalt, more wind turbines, more solar, all in place and working. Then we can shut down fuel production.

        Not granting licenses to an in demand product does nothing to stop consumption. All it does it cede political power to other countries who don't give a flying fuck. The correct solution is to eliminate the demand by finding alternatives.

        Remember the solution to the ozone layer was not to ban production of CFCs, but rather to ban their use.

• According to Wikipedia:

  What is the difference between "largest" and "most powerful"?

    Poor wording. Hunga-Tonga was the largest volcanic eruption [that has happened since] the 1991 eruption of Mount Pinatubo, and the most powerful eruption since the 1883 eruption of Krakatoa.

    • Thanks for the link.

      I think what they are saying is that Hunga-Tonga was the largest in terms of volume displaced since Pinatubo and the most powerful in terms of instantaneous pressure since Krakatoa.

      So Pinatubo pushed out a lot of magma but over a longer period, while Krakatoa had a bigger single explosive event.

• Honest question here: the ozone hole in the northern hemisphere was of concern because of the local populations living under it. But in Antarctica, the only danger is skin cancers in penguins.

  Unless the hole is drifting north of course.

  • The hole over Antarctica is a symptom of a global reduction in stratospheric ozone. We use it because it is easy to measure. But the problem is global. Less ozone means more UV, more skin cancer, more crop damage, and more harm to many ecosystems.

    • Re:

      Okay thanks. I didn't realize. I thought it was a purely local thing.

• But have they really? Do they measured all possible ones? Because illegal operations in china have had a habit of dumping this crap and in some cases some factories still producing CFCs or variations thereof.

  Lets hope it - and the recent sudden temperature rise this year globally - are simply down to that volcano and not something a bit more long term and concerning.

• People who take it serious are already doing what they can and the rest wouldn't even care if cancer rates suddenly exploded hundredfold.

  They'd simply start a new conspiracy nuttery how Biden makes them sick.

  At this point, I doubt that we will do anything to save ourselves. And frankly, I don't even know anymore whether we should change that. Maybe it's better we remove ourselves from this planet and maybe in a couple million years, the next species developing sentience will be more sensible.

  Or some aliens

• this is one of the reasons why flying on H2 may not be such a good idea. More water will be emitted at high altitude, causing a climate effect on its on and destroying the ozone layer.
