I would have so passes my math classes if I would have thought about it in this way.

Have you ever been to a glacier? I have this last August. Glaciers are not permanent monoliths of ice. They are in a constant state of flux. For the head of a glacier to it's melting point can range from as little as 50 to hundreds of years. They ebb and recess constantly and the span of human history during which we have accurately and scientifically been recording their movements is not sufficient to make predictions as to their future.

Birth defects....so true.

Apparently, having visited a glacier makes someone an expert.

Or maybe not.

Good graphic!
