The Conversation reports[1] that according to research by Dr. Charles Lineweaver and Dr. Aditya Chopra, a plausible solution to Fermi's
paradox is near universal early extinction of life on exoplanets,
which they have named the Gaian Bottleneck.
[...]
According to the researchers, most early planetary environments are
unstable. To produce a habitable planet, life forms need to regulate
greenhouse gases[2] such as water and carbon dioxide to keep surface temperatures stable.
[...]
"Even if life does emerge on a planet, it rarely evolves quickly enough
to regulate greenhouse gases, and thereby keep surface temperatures
compatible with liquid water and habitability."
