Watching global warming

We don't have a problem of economics, technology, and public problem. We have a problem of perception. James Balog of Extreme Ice Survey

The problem of perception is that people don't see global warming. They think it's all pointy headed scientists and computer models, neither of which can really be trusted. Balog's TED presentation shows the effect of global warming on glaciers, not through measurements and graphs, but through time-lapse photography.

Watch the presentation.

Even if you already know that climate scientists have it right, even if you already know that spring is coming earlier, even if you already know that the earth is getting warmer, you'll be astonished at the scale of the impact we're having.
