Alien apocalypse: Can any civilization make it through climate change?
Does the universe contain planets with truly sustainable civilizations? Or does every civilization that may have arisen in the cosmos last only a few centuries before it falls to the climate change it triggers? Rochester astrophysicist Adam Frank and his collaborators have developed a mathematical model to illustrate how a technologically advanced population and its planet might develop together, putting climate change in a cosmic context.

We think we’re the first advanced earthlings—but how do we really know?
Imagine if, many millions of years ago, dinosaurs drove cars through cities of mile-high buildings. A preposterous idea, right? In a compelling thought experiment, professor of physics and astronomy Adam Frank and director of the NASA Goddard Institute for Space Studies Gavin Schmidt wonder how we would truly know if there were a past civilization so advanced that it left little or no trace of its impact on the planet.
