Evidence
Evidence for Habitable Zones & Planetary Climate
Solar-System planets show dramatically different climates despite similar materials, and climate models reproduce broad dependencies on insolation and atmospheric composition. Exoplanet observations constrain stellar flux, planet radius, and in some cases atmospheric properties.
Chapter review
Assessment still in review.
The chapter is published, but its assessment has not completed the verification and QA pipeline yet. It will appear here after publication.
