       | No, the real question is how to keep the earth from being cooked
       | by _greenhouse gases_ , not in 500 million years, but actually in
       | a few decades. This article borders on climate change denial.

         | Alarmist statements hurt more than they help fight human caused
         | climate change.

           | Given that CO2 emissions have only ever increased, it seems
           | like everything hurts more than helps the fight against
           | climate change. For what it's worth, I'm reasonably convinced
           | that the answer is 1980 and that, like a lethal dose of
           | radiation, the damage is done and now we merely wait for the
           | effects to take hold fully.

           | interest not to hear about it.

             | Maybe people are just tired from the same old alarmism
             | which is then used to introduce more and more limitations
             | and never touches the biggest offenders. Sure, introduce
             | the next tax, lovely. Hope Nestle doesn't get touched.

               | The measures against climate change have been so weak
               | until now that I don't think we can even talk about
               | limitations yet. At least there's some equality here I
               | guess, nobody doesn't do anything.

               | The measures against climate change has been weak
               | precisely because of alarmism.

               | If everything is going to shit anyways, why throw
               | resources into a black hole fixing it today? Check how
               | many headlines have been saying inevitable, point of no
               | return, etc etc for several decades.
               | 
               | Another aspect of this is overfitting on metrics like CO2
               | emissions, that's how you get hot garbage like carbon
               | offsets that allow the worst offenders to keep operating
               | like they have always been.

               | You live in a parallel world, the vast majority of the
               | mainstream news out there are outright climate change
               | deniers funded by billionaires and the few ones who don't
               | cannot even relay the whole truth for being accused of
               | "alarmism".
               | 
               | The reason nobody does anything about climate change is
               | because it threatens their wealth, not because it's a
               | catastrophe.

               | In my 'parallel world', it does seem like the mainstream
               | media publishes articles every week or so (for the last
               | decade or so) about how we are at the point of no return
               | for climate change. And all of it is preserved in this
               | wonderful searchable web of articles that ensures one
               | does not have to speculate about what was published.
               | 
               | Maybe search on the web, who knows, it could turn out
               | that you too live in the same world!

               | What if in 50 years it turns out alarmists were right,
               | and there's nothing could be done? Anti-alarmists will
               | say "oopsie, we were wrong, you were right, now we see".
               | But it won't help.
               | 
               | Imagine there's a huge asteroid comes at Earth, but it
               | will strike only in 100 years. Alarmists start screaming
               | that we need to act NOW, but anti-alarmists would be like
               | "oh come on, you're screaming it for the last 44 years,
               | please stop".
               | 
               | People are pretty bad at solving long problems.

               | earth with the benefit of subverting this dangerous thing
               | if it does exist?
               | 
               | The clincher here is that most of the greenhouse gasses
               | come from giant corporations. As non-billionaire
               | individuals, we don't have to personally give anything
               | up. All we have to do is get those corporations to stop
               | polluting simply because it's more profitable in the
               | short term.

         | Its telling something entirely different. Also it tries to give

       | This sentence from the article seems to be completely made up and

       | "Without water to lubricate tectonic activity, our plates will
       | grind to a halt."
       | 
       | In fact, water has nothing to do with tectonic activity, and the
       | "lubricant" seems to be a special kind of molten magma:
