What global warming means is new distribution fights for ressources.
We have had the ability to harness virtually unlimited nuclear energy since the 1950s. Argument 1 â" utterly debunked. If our survival depended on it I'm sure we could chuck a few hippies into the sea and get back on track with fission (As China is already doing on a massive scale). With recent advances in hydroponics and agricultural technology, I'd say we're on track to feed the world of tomorrow no sweat.
Even small, local climate changes by moving trade wind patterns caused civilisations to collapse, accompagnied by war, pandemics and devastation of large regions.
Civilizations have also collapsed over things such as: Taxes, Family Feuds, Middle Management, Bananas, Sexual Insecurity, Poor PR and more! Climate Change in this context is utterly irrelevant. Civilizations come and go all the time.
we face a global war, and we still have overkill capacity -- even if we don't use the nuclear arsenal.
Earth is more peaceful than it's ever been in the history of mankind. Food is cheap and abundant. We've built intelligent machines, travelled to the moon, split the atom, and (With the help of theUS, EU, downfall of USSR, globalization, Internet, etc.), have built a stable, interconnected world such as has never been seen. Why all the damned pessimism? For some reason going from horse and carriage to space travel in 100 years isn't good enough for you guys? I honestly don't get it and it's sad state of things that people have stopped dreaming about the future.
"Fire in a Crowded Theater" was made up in US vs Schenck to argue for the conviction of Charles Schenck, a socialist, because he argued against the draft in WWI. You know, back when we put those filthy socialists in jail, instead of letting them run for president.
I can tell you right off the bat that Fire in a Crowded theater ALSO does not apply as an "exception" to the first amendment. It has no legal standing whatsoever. You could go yell fire in a theater today, if you're feeling up to it, and I guarantee you won't be prosecuted for speech. You'll get arrested for disturbing the peace, perhaps, but it's a free country and you can say whatever you want unless it's BOTH intended to be malicious and blatantly, knowingly false. If you actually thought there was a fire, you would be in the clear, since our legal system operates on INTENT and not what is politically correct or not.
1st Amendment has no exceptions. The closest thing to an exception would be national security secrets (Which, ironically, is partially the fault of Trump's #1 opponent), which we are fighting passionately in the courts right now.
We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
