I know the Sun will slowly increase its brightness and size before becoming a red giant and will boil the Earth's oceans in a billion years more or less.

But do astrophysicists know when it will make human life on Earth hard to sustain? And I mean by that when the Arctic becomes as hot as nowadays Saudi Arabia.

Climate change is going to do that in 100 years unless we all start voting for Democrats.

Supposing global warming doesn't accelerate it much, forgot to say.

some time between now and when it boils the planet
stellar evolution is fairly well understood but your answer will only be accurate to some millions of years

Actually this would have happened about 300 million years ago. But life on Earth worked hard to remove all these greenhouse gas from the atmosphere. Unfortunately some stupid apes burn all this coal and oil and now the planet is heating up like mad.

Why would emissions triple by 2080 if its projected that at current rates we will have nothing to burn by 2060?

In 500 millions years there will not be enough CO2 in the atmosphere. Plants will die. I've read it somewhere I'm not sure it's true.

Because emissions are not only from burning but also from things like permafrost melting. Positive feedback loop ya know.

>anyone raping the 3rd world financially
Migration itself isn't the problem, the problem is permanent citizenship.
This fucks up the 3rd world financially through brain drain.
This is even a problem within Europe.
Eastern European countries typically receive more money from the EU than they contribute looking like a net gain on paper.
The issue is that they are also exporting their most qualified workers to the west, leading to loss of investment that doesn't appear on the books.
If everyone capable of developing a country is leaving, it isn't going to develop.

Citizenship migration in combination with welfare states is also highly exploitable.
The more wealth that is in the hands of consumers, the better for corporations.
Anyone below the poverty line must spend all they have on subsistence, and is thus a guaranteed consumer.
Anyone above the poverty line has disposable income, and is thus a potential saver.

1. Subsidize unsustainable birth rates in the 3rd world (philanthropy)
2. Import into 1st world welfare states
3. Redistribute from savers to new spenders
4. Sell more things to more new spenders
5. Profit
You can have migration, or you can have welfare states, but you can't have both, at least not sustainably.
