[Fresh Wind]

Global warming is making the Earth expand!

It's not that simple. All the oil we're pumping out of the Earth is making it shrivel up like a raisin. Burning that oil is causing Global Warming®. So, both problems can be blamed on the same evil people.

[Political Junkie Too]

And then all the breeding that's going on in some parts of the world is putting extra weight on the surface.
