Earth’s climate has remained continuously habitable throughout 3 or 4 billion years. This presents a puzzle (the ‘habitability problem’) because loss of habitability appears to have been more likely. Solar luminosity has increased by 30% over this time, which would, if not counteracted, have caused sterility. Furthermore, Earth’s climate is precariously balanced, potentially able to deteriorate to deep-frozen conditions within as little as 1 million years. Here I present results from a novel…

Towards a Classification Scheme for the Rocky Planets based on Equilibrium Thermodynamic Considerations
A classification scheme for rocky planets is proposed, based on a description of the Earth System in terms of the Landau-Ginzburg Theory of phase transitions. Three major equilibrium states can be

Evolution of a Habitable Planet
■ Abstract Giant planets have now been discovered around other stars, and it is only a matter of time until Earth-sized planets are detected. Whether any of these planets are suitable for life
Superhabitable worlds.
TLDR
It is illustrated how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ and why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like.
Gaian bottlenecks and planetary habitability maintained by evolving model biospheres: the ExoGaia model
The search for habitable exoplanets inspires the question - how do habitable planets form? Planet habitability models traditionally focus on abiotic processes and neglect a biotic response to

TLDR
The chronology of Life emerged on Earth within the first quintile of its habitable window, but a technological civilization did not blossom until its last, and for intelligence evolution, it is found that a rare-intelligence scenario is slightly favored at 3:2 betting odds, but intelligence may not be as inevitable.
No snowball on habitable tidally locked planets
The TRAPPIST-1, Proxima Centauri, and LHS 1140 systems are the most exciting prospects for future follow-up observations of potentially inhabited planets. All orbit nearby M-stars and are likely

Earth's climate is buffered over long timescales by a negative feedback between atmospheric CO2 level and surface temperature. The rate of silicate weathering slows as the climate cools, causing CO2
The Resilience of Life to Astrophysical Events
TLDR
Surprisingly it is found that although human life is somewhat fragile to nearby events, the resilience of Ecdysozoa such as Milnesium tardigradum renders global sterilisation an unlikely event.

Catastrophes in our solar system have played a big role especially during its early evolution, e.g., the formation of the Earth’s moon or the slow retrograde rotation of our sister planet Venus can
