The sun will get much hotter, long, long before it expands to become a red giant.
It will only take another 1 billion years for the sun to become hot enough to vaporise earths oceans, and life for humans and other livings things will become intolerable well before that - as soon as 300 million years from now.
Human induced climate change (global warming) will accelerate the whole process.
Gosh, will my progeny 3,000,000 generations from now curse me for replacing the V6 truck I bought last year with a V8 truck this year, instead of getting the Prious?! Curse my foolish desire to get to 60mph 1 second faster, thinking like that may doom us in only 2,999,999 generations.
I don't know, I have a hard time getting to worked up about theories on what will happen in 3m generations. First, look at how much technology has changed in 20 generations. (I'm using 100 years as a generation for easy numbers)
We've gone from "Hmmm fire hot" to chatting about travelling to other planets on computers that fit in our pockets.
That's in
20 generations, it's pretty difficult to guess what the problems of the day will be in 1m generations, let alone 300m. Odds are pretty good we'll be the, "Hmmm fire hot" guys in 100 generations, let alone 300
m.
I'd also note that around here the last two winters were some of the coldest on record, and we've also had very cold summers recently.
