Big Picture Science - Anthropocene and Heard

What’s in a name? “Holocene” defines the geologic epoch we’re in. Or were in? Goodbye to “Holocene” and hello “Anthropocene!” Yes, scientists may actually re-name our geologic era as the “Age of Man” due to the profound impact we’ve had on the planet.

We’ll examine why we’ve earned this new monikor and who votes on such a thing. Plus, discover the strongest evidence for human-caused climate change.

Also, why cities should be celebrated, not reviled… a musing over the possible fate of alien civilizations … and waste not: what an unearthed latrine – and its contents – reveal about ancient Roman habit and diet.
