The idea of any group of humans "saving the Earth" is neighbouring on hubris. It's fine for the plot line of a Hollywood movie, but pragmatically we can't even engage in civil discourse anymore. Tampering with systems like plate tectonic without the ability to even predict the effects of oil shale fracking means we still have a lot to learn.

If the concern of the Earth being wiped out is legitimate, then focus instead on colonizing Space. The end result is the same: preserving human civilization.

I wouldn't say the end result is the same just because humanity survives. I mean, say the eruption occurs and as a result only a few billion people ultimately die. Well, human civilization is preserved. But it would be a lot more pleasant to prevent it happening at all.

Achieving the technology required to colonize space would also allow us to maintain our existence on Earth.

Exactly my point.
