When the earth dies, where will you read about it?

Certainly not in the Daily Planet, unless Superman keeps the paper going longer than the planet that it's named for.

Paper.
Perish.
Paperish.

And what will be the cause of death?

Probably global warming, but not the global warming that's slowly upping the temperature until the whole planet is one big beach.
(Or one big ocean with one tiny beach, at least.)

Swimwear.
Earth.
Swimwearth.

More likely the global warming that the sun emits when it explodes and takes out the whole solar system, including our new beach.
(Perhaps a better name would be global heating.)

Explode.
Ding ding ding!
Exploding ding ding!
