1. Epochs last an awfully long time. We’re talking millions of years. Well, some scientists are kicking around the idea that the earth has entered a new one. Technically, we’re still in the Holocene period. But perhaps, these scientists say, humans have so influenced the direction of the planet that we should think of this as a new epoch called the anthropocene. Check out the above video for a  visualization of this idea.

    In connection with the NPR Cities Project today, NPR Blogger and astrophysicist Adam Frank suggests that the anthropocene is really the epoch of the city. Just look at the east coast from way up in an airplane, he says.
