The Anthropocene

A waterside factory with many stacks belching smoke into the air

Geologic time is divided into units like eras (like the Cenozoic) and periods (such as the Jurassic). These span millions of years. Then there are relatively shorter epochs: The Holocene epoch started 12,000 years ago. Now some scientists say we've entered a new epoch: the Anthropocene. This name reflects that humans are now the major cause of changes in our planet’s climate and environment. We’ll learn about the Anthropocene and what it means about our impact on Earth.

Jonathan was born in Monsey, New York. A field trip to Washington, DC when he was in 7th grade started him on his circuitous path to a career in public radio. The trip inspired a love of politics and led to his desire to one day call DC home. After graduating from Grinnell College, he worked on a couple of campaigns in Iowa (presidential and congressional) and moved to Washington, DC.
