The Faint Young Sun Paradox and Why Trees Are Green
The article is devoted to the significantly underestimated contribution of radiation from the young Sun to the formation of physical conditions on the early Earth. A new view on the faint young Sun paradox is presented: the main role in solving the paradox is given to the impact of the increased activity of the young Sun on the Earth’s atmosphere. The role of planetary organic films is considered as a climate-forming factor involved in resolving the faint young Sun paradox. The spectrum of radiation of the young Sun and the paradox of the discrepancy between the chlorophyll absorption spectrum and the spectrum of solar radiation are discussed, and also indicated a possible connection between the faint young Sun paradox and the origin and evolution of photosynthesis on Earth.
期刊介绍：
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
