If by some miracle humans are alive in 1 million years they sure would be able to deal with a bit of more sun, launching bunch of mirrors in space or something.huh,
You do realize that in about 500 million years the sun will get hot enough to make almost all multicellular life extinct? It would take intelligent life of the time to make the Earth go further out in orbit to ameliorate it.
At any rate, I need to start going back to websites like resilience.org that talk about getting ready for the shit to hit the fan. It is as about as positive and mainstream as those types of sites get.
Agreed. The warming of the sun as the years go by is not a meaningful threat to mankind. If we are around as a technological species we can deal with it.
It's important in the global warming debate, though, because one of the false rebuttals is to point out the higher CO2 levels in times past and pretend that means higher levels now will have the same effect as they did back then.
