There’s no science that says that. Talk like this only gives fuel to climate change deniers.

We will make a deal, then. 10 years from now, I will give you 100k units of currency from a country. 15 years from now, you will give me 10 million units of that currency. The country must have steady state inflation of the preceding 5 years of under 10%. The country must be one of the ones you believe will become uninhabitable.

Easy money for you since you can convert to a safe currency and then pay out in the worthless currency later.

If no country meets the requirements, we just fold and there's no deal. But if one does, you've got yourself free money. If you think you'll have trouble with obtaining units, we can run it like a swap in what you believe to be safer currency.

I'll need a written contract so I'll send someone to you if you're in San Francisco.

Ah, but only 22 years left until Kurzweil had estimated that the singularity would begin, which prediction is looking increasingly prescient. So. You might just be able to upload yourself and live indefinitely.

The statement above could be wrong. You could also be wrong. (Certainly very few people are acting as though they believe that CO2 emissions are going to turn the Earth into an uninhabitable flooded fireball.) But techno-optimism beats pessimism, easy. If nothing else, it makes it easier to live with yourself.

I think that climate scientists are making accurate, reliable predictions when it comes to climate change- however, I have not heard any climate scientist saying things this extreme. It's important to not distort the situation in either direction. The earth will likely heat by 3 degrees C or thereabouts but it will take 50 years or more to get there, from what I understand.

It would quite a cosmic irony that humanity reaches eternal life right when their planet is unliveable.

Much of the planet? Really? I can understand writing off Phoenix, AZ or parts of South East Asia and the Middle East.

Every 15 years we have someone who says globalwarmingclimatechange will make Earth uninhabitable in 15 years.

The issue is not "what percentage of landmass is uninhabitable" but rather how many will no longer be able to afford food and water, be admitted to refugee camps and if the rich will be willing to share these things with the poor. War is another potential factor.
