I have to disagree. Look how much humanity has changed in the last million years. We'll change that much in the next. Only globally.
Even if the world became a total wasteland, it wouldn't be over-night most likely.
Besides there are several 'planet sized' moons which wouldn't be too hard to set up bases on. We think of moons as tiny, but many of them are pretty big For example..
The earth is about 8000 miles across. Our moon is about 2000.
First you have Ganymede, then titan. Both of these are over 3000 miles. There are Triton and Io.
Callisto, Europa.. The hard part is
Io, Titan, and Triton all have atmospheres, and in Titan's case.. a really good one.
Not to mention Mars and Venus, which could both easily support small pockets of humans in domes.
Venus, could have it's atmosphere processed to convert much of it's CO2 into Oxygen. It wouldn't take that long (at worst 1000 years) to do that. While 1000 years sounds like a lot, it isn't really when you consider what you are doing.
Venus' atmosphere is dense, that would lighten it considerably.. It should be pretty easy to fly through the atmosphere indefinitly, with planes/airships that use the sun to produce energy. It is questionable as to if you could ever breathe the air... but you could harvest the oxygen from it easily. Infact.. You could fly perpetually through the air to releave pressure while you gradually make oxygen. So during that 1000 years you could be living there. The surface is under about 90 times the pressure of earth.. But that is nothing compared to deep sea vessles.
And mars is a different story.. There is little hope of ever being able to walk free on the surface of mars.
Regardless.. There are enough close planetary bodies to ensure humanity exists at least 1 more million years. Potentially the 4.5 billion.. By then, I'm sure we will have been to other systems. The galaxy is only about 300,000 light years across. If we managed to travel at 1% the speen of light, which wouldn't be hard with even modern technology in the form of ion thrusters. (given a heafty accelleration... like 500 years. If we went 1% of the speed of light, it would only take 300 million years to traverse the entire galaxy. Infact... We could reach another galaxy before our own sun died, if we really wanted too.
The nearest star is over 4 light years... Which would take about 400 years to get too at 1% the speed of light. However.. It would take as much as 10 times that long to get there due to acceleration.
needless to say. Starting in our own solar system is the key. And If we put our minds to it, we could have bases on at least 5 bodies within the next 100 years.. It'll likely take 10 to 100 times that long in reality.
If I am lucky, I'll get to see the first one. Assumeing we don't eliminate aging before I die... Which is a possibility.
