We'll put a giant sunshade in the Earth-Sun L1 Lagrange point.

We might need to do that by the end of this century.

If we are able to harvest the solar system resources it would take by then.

Trial run for the bigger “solar warming” event.

See, it all comes together! ^.^

Sadly it is still only a stop-gap measure. The sun is for all intents and purposes, dying a slow death.

Sure, but it may keep Earth habitable for an extra billion years.

Unfortunately it looks like we are more in the track to human inhabitable earth :(

Long before death it will expand to or almost to Earth's orbit. I doubt humanity could isolate Earth from that.

Yeah, but if humans exist by the time the sun fails us, they wouldn’t really be the same species as us, and they’d hopefully have progressed to the point that they could escape the Earth.

You're saying we wont maintain tradition and our "humanity"?. I like to be a little more optimistic and believe in us as a species transferring values until the end.

Look at all types of mammal that exist, from us to platypuses to bats to whales. Evolved in a few hundred million years. Modern humans have been here for a few hundred thousand.

In 500 million years absolutely anything could happen (if we survive this century).

Sure, and entropy will end us all one way or another

We'll have colonized the galaxy in 10 million years. In 200 million years, I'd expect that some future historical society could undertake a project to clean out the heavy elements in the Sun to keep it going.
