The sound you hear

In a video I linked to previously, a visiting speaker gave a pretty rousing, if pessimistic, take on the current state of affairs in our lurch toward inalterable climate change, with added emphasis on how our renewable fuels development strategies are exacerbating the situation. He offered a pretty concrete demonstration of what happens when glaciers melt, using a chair and a table at the front of the room. It’s not like they slowly melt away to nothing over the course of eternity; instead, like a chair leaned against the end of a table, they reach a point, a tipping point, where their melting slide dissipates the friction holding it in place and allows the glacier to fall into the sea. Like the chair falling to the floor. Very dramatic.

Kind of like this.
