CURRENT models for the evolution of the Sun require an increase in solar luminosity by 25% since the formation of the Solar System1. Such an increase in the solar constant should have profound effects on the terrestrial climate, but there is no evidence from the fossil record of a corresponding change in the Earth's global mean temperature2. This apparent conflict cannot be explained by the apparent inability of solar models to account for the low observed neutrino flux3. Even models that are… 

Nitrogen-enhanced greenhouse warming on early Earth

Early in Earth’s history, the Sun provided less energy to the Earth than it does today. However, the Earth was not permanently glaciated, an apparent contradiction known as the faint young Sun

The faint young sun-climate paradox: Continental influences

We examine the various mechanisms which have been proposed to compensate for the climatic effects of a 30% increase in the solar luminosity over the past 4½ billion years. Although atmospheric

Greenhouse warming by CH4 in the atmosphere of early Earth.

TLDR
It is found that a CH4 mixing ratio of 10(-4) (100 ppmv) or more in Earth's early atmosphere would provide agreement with the paleosol data from 2.3-2.4 Ga, which could have triggered the Earth's first widespread glaciation.

A study of the radiative effects of enhanced atmospheric CO2 and CH4 on early Earth surface temperatures

Large concentrations of atmospheric CO2 in the atmosphere of the early earth have been proposed as a possible explanation of the apparent absence of frozen earth in spite of a faint early sun.

Photochemical Consequences of Enhanced CO2 Levels in Earth's Early Atmosphere

Greatly enhanced atmospheric CO2 concentrations are the most likely mechanism for offsetting the effects of reduced solar luminosity early in the earth's history. CO2 levels of 80 to 600 times the

Carbon dioxide, ammonia and the origin of life

Stellar evolution theory predicts that the luminosity of the Sun has increased by ∼30% over the past 4,000 Myr. Yet geological and biological evidence indicates that the climate of the Earth between

Earth’s long-term climate stabilized by clouds

The Sun was dimmer earlier in Earth’s history, but glaciation was rare in the Precambrian: this is the ‘faint young Sun problem’. Most solutions rely on changes to the chemical composition of the

Susceptibility of the early Earth to irreversible glaciation caused by carbon dioxide clouds

TLDR
The authors' simulations of the early Earth, incorporating the possible formation of highly reflective CO2 clouds, suggest that the Earth might not be habitable today had it not been warm during the first part of its history.

Is the Faint Young Sun Problem for Earth Solved?

Stellar evolution models predict that the solar luminosity was lower in the past, typically 20-25% lower during the Archean (3.8-2.5 Ga). Despite the fainter Sun, there is strong evidence for the

TLDR
The hypothesis of an early methane-ammonia atmosphere is found to be without solid foundation and indeed is contraindicated, and arguments concerning feasible components support the view that amino acids and proteins preceded sugars and nucleic acids.

Mars and Earth: Origin and Abundance of Volatiles

TLDR
The perspective gained through the present investigation suggests that this is not a necessary condition for planets at the distance of Mars from a solar-type central star, and if it turns out that Mars is completely devoid of life, this does not mean that the zones around stars in which habitable planets can exist are much narrower than has been thought.
