...When you've only got a billion years to live. Options

[Dogmeat]

In fact, even during its life in the main sequence, the Sun is gradually becoming more luminous (about 10% every 1 billion years), and its surface temperature is slowly rising. The increase in solar temperatures is such that in about a billion years, the surface of the Earth will become too hot for liquid water to exist, ending all life.

Folks, it's time for action. We need to start a campaign to save the Sun now ... in a billion years it will be far too late. We need to act now! We simply cannot let the Sun heat up and destroy the Earth! Stop Solar Warming Now!

I joke about this but I am not kidding that this literally givs me nightmares when I think about it
