Yep, I think its serious. The polar ice caps have already begun melting rapidly. Ironic ins't it? A few years ago we thought we'd die because of the explosion of the sun, but now its we're going to drown because of all the ice melting.

How would anyone know that?
(I exaggerated with billions. Maybe millions.)
Just a question: Why do they in the movies try to destroy us? They've always been unclear on the reason.
