  • Discover what caused the hole in the ozone layer, and how the Montreal Protocol helped restore it by banning harmful chemicals.
    --
    In the 1980s, the world faced a huge problem: there was a rapidly expanding hole in the ozone layer. If it continued to grow, rates of skin cancer could skyrocket, photosynthesis would be impaired, agricultural production would plummet, and entire ecosystems would collapse. So, what happened? Stephanie Honchell Smith shares how decisive global cooperation helped restore the ozone layer.
    Lesson by Stephanie Honchell Smith, directed by Denys Spolitak.

      That the world acted quickly and universally when the evidence was irrefutable is my take away.
      I have always found this to be the most damning inditement to place at those making the current 'climate crisis' clamour.
      The Montreal Protocol - to me - is demonstration that the causes and proposed interventions - to do with the 'climate crisis' are not as clearly understood or defined. For example, I have seen estimates of this being the most effective intervention to deal with 'global warming', yet I see very little celebration of this.
      Low cost, nothing to do with CO2, universally adopted...

    Pursuing profit at the expense of nature's wellbeing is just a symptom of a deeper underlying issue. Only when we recognize that we are not a separate entity from our environment, will change in a beneficial direction begin to take place. Just because we live behind walls does not mean that we are any different from the organisms that dwell outside of them.

      Some of the countries that could do something about it are seeing the effects too, but social media, misinformation and influential people are getting in the way of an actual understanding of the problem by the majority of the population.
      And nowadays, I doubt that a politician getting skin cancer would influence them in their political actions…

      The ozone hole has always been there. Ozone is created by sunlight. When there's a place that gets no sunlight for six months, you get a hole. It's not going to "go away entirely" unless the sun gets really, really awful. CFCs just made the hole bigger, and thinned it out in places the hole wasn't. But the actual existence of a hole is completely normal.

    I think the biggest problem with the current climate issue is that it’s not as readily apparent (even excluding the capitalistic mindset of maintain oil based companies). With the ozone hole, it’s pretty obvious to find out you have a hole in the sky that could kill the planet.
    With Climate Change, “oh, we don’t need to do anything, it just makes the planet warmer”. By the time we do see anything for climate change, it’ll be too late. If you haven’t seen the increasing number of natural disasters and the flooding at coastlines, then you’re living blindly. Please please, convince our legislature to take action. There’s only so much humanity can take now.

    • @darrennew8211
      @darrennew8211 Год назад +4

      The reason we knew about the ozone hole is it's a completely natural thing people had been tracking for decades. Any time you don't get sun for six months, the unstable chemicals created by sunlight tend to fade away. That's why the hole was over Antarctica instead of (say) the USA.
      The difference between the situations is that it's relatively easy to replace refrigerants with different refrigerants. It's relatively difficult to replace fossil fuels with anything else.
      And we've done studies showing that neither coastlines nor "natural disasters" are any more in danger than they've been for the last hundreds of years. No more hurricanes, tornadoes, or floods have been measured.

      What?
      Just google search the U.N climate report to know how wrong this is.
      Where are you getting this nonsense about disaster levels being the same for the past 100 years?
      And the ozone breaking is not a "natural process that was going to happen anyway"
      That's entirely wrong, and your logic of "well how come the hole isn't over the U.S" shows you did zero research on the topic and insisted on criticising it anyway.
      The ozone layer is over the arctic because that is the only location cfc's can chemically collide with the ozone. During an event called the "polar vortex" every winter, arctic's thin atmosphere leads to a strange stratospheric reaction that forms a funnel.
      This funnel creates a doorway for stable chlorine gases in low atmosphere, like cfc's, to find their way to the stratosphere and perform a chemical reaction caused by the colliding molecules, leading to a reduction of the ozone. This is not natural. CfC's are able to perform thousands of collisions before becoming stable. The vortex is not a "natural ozone hole" it's just phenomena where the ozone becomes thinner for six months.
      Anywhere else on earth cfc's are trapped in low atmosphere as "chlorine reservoirs" and are relatively harmless until given enough time to migrate to the stratosphere.
      There are scientific models on this. It's been proven definitively. Just search for ozone watch to see the details.
      Educate yourself. Please.

Whole generations of us have to be extra careful in summer, covering up and hiding in the shade or getting burned in 15-20 minutes. As someone who has worked outside for some years, it is a big concern for about half the year, even avoiding excessive sun exposure in late winter.

    CFC is not a coolant, it’s refrigerant. Key difference is a typical coolant don’t undergo phase change in the heat transfer system. While a refrigerant undergoes phase change, and the phase change is critical to the function of the refrigerant. This is why it’s not as simple as switching out water with diluted antifreeze, the whole refrigeration system (operating pressure, expansion valve opening, compressor) needs to be redesigned or at minimum adjusted.
