David is speaking at the Space Telescope Science Institute in Baltimore, MD on Tuesday, April 29th 8pm in the STScl Auditorium! Don’t miss out if you are in the area (webcast option available too!). Click me for more information or see below.

David will discuss (in his own words) “the current human-dominated phase of our planet’s life into a broader context, juxtaposed against previous geological eras in Earth’s history, as well as what’s known from studying changes on other planets. The goal is to better understand the essence of our current moment in geological time and what it means for intelligent life in the universe and for the future of our civilization.”

The talk will be webcast here as well!
