Does climate change have made alien apocalypse?

Astronomers have inventoried stars, galaxies, comets, and black holes in the universe. But are the planets with sustainable civilization also something that exists in the universe? Or does any civilization that might appear in the cosmos lasted only a few centuries before falling by climate change?

Astrophysicist Adam Frank at the University of Rochester and colleagues has taken the first step to answer these questions. A report in Astrobiology tries to map out the answers to these questions from an astrobiological perspective.

"Astrobiology is the study of life and its possibilities in the context of the planet. That includes 'exo-civilizations' or what we usually call aliens. If we were not the first civilization of the universe, that would mean there might be rules for how the fate of a young civilization is like our own progress," Frank said.

Discussions about climate change rarely occur in the wider context in cosmic history that planets and biosphere have evolved into something like what humans have done on earth. Population growth increasingly uses resources and civilizations to change the conditions of the planet.



"Climate change may be something generic, the laws of physics demand every young population, build an energy-intensive civilization and feedback on the planet.Seeing climate change in this cosmic context gives us a better insight into what's happening to us now and how to deal with it," Frank said.
