Earth's recent climate spiral.

[Leonardo17]

I don’t remember the clear figures but it is the 1% very rich people of the world who are causing more than 50% of climate change.
 
On thing he is right about is that: “We are nice but we are too many”.
 
I think the ideal population of this planet is around 4 billion. A 10 billion planet is simply not possible.
 
See how he is able to tap on such real facts to distort the whole story and even turn it into “coal can still go on”.
 
-       No it can’t. We have to find ways to completely abandon fossil fuels by 2050. Than we can have a chance as a specie. Otherwise we don’t. And these are facts.

Consider how the bolded bits persuasively argue against each other.  It's not the number of people, it's how we organize our lives and industry.  The original malthusian predictions failed for the same reason.  7 billion or so reasons, to put a fine point on it.  Similarly, Marion Hubbert was wrong about peak oil in the 50's, then it's revamped advocates fucked the pooch again in the start of the 00's.  

We won't abandon fossil fuels by 2050.  It wouldn't surprise me if they're still around in 3050.  We still have windmills and water wheels and steam power, too.  Thus, the real issue, is how we plan for a future that doesn't depend on magical thinking in the form of a global warming benefit or a post ff world.  Ultimately, the issue is to do what we should have always been doing, and make better use of and take better care of our resources even without considering things like global warming.  

We've squandered a great deal of the very stuff we'll need to build that future world, and, in the long term...imo... that's even worse than the incidental effects of squandering it.   So much worse, that unless we get better -at that- then cutting back on carbon is polishing brass on the titanic.  In that larger context, people aren't the problem, we're the solution.  We're the only things we know of that even give a shit about this world - and it's going to take alot of us doing alot of actual labor.  We're certainly the only things capable of effecting the sorts of changes we're seeing now for the worse..but there's no reason we couldn't make it better.  Case in point, a green sahara?  If we want a green sahara then there's no reason to let global warming make one at the expense of so many of us.  We can do it directly.  Seems to me like we might even need the practice, if our hare brained two planet idea is supposed to be anything other than a shameless con.  Not particularly difficult in theory, just one hell of an engineering project.  Africa has a massive untapped reservoir of water.  Pump it.  Block the wind, slow down the water, introduce deep rooting and matting invasives and grazers to spread them.  Monetize the gains.  All of that could only be elective, though, just something we do because we want to...it's not like we need it.  We already grow enough food for 10b or more people even though we do it in a horrendously dumb way, by turning ff's into food.  Hasn't kept us from starving, either, so I guess there's also that.

1) Population is naturally decreasing wherever women are gaining more control over their own bodies. The population of Europe is declining despite immigration. The abandonment of the one child policy in China is also not leading a population boom in China. People cannot afford to have children so those who don’t like them make the choice of pursuing their own careers instead.
   So it doesn’t need to be pushed. If you just leave it on its own, population will decrease to 4 billion. Just educate women instead of marrying them at the age of 14 and this alone will do it.
 
2) That’s an important point too. But the fact is: We have carbon capture technology that can work with nuclear or geothermal energy. But what is it good for if we keep extracting oil and coal? I think methane and oil can still have some sort of future but coal must be immediately phased out. We don’t need that anymore.
   + You are right on the good usage of energy resources. For instance cryptocurrency factories are extremely demanding in terms of energy. So why do we have them in an age of global warming? I think these should just be banned until they become less demanding in their production in terms of energy.
 
3) I agree
