Behaviors of Martian CO2-driven dry climate system and conditions for atmospheric collapses
Yasuto Watanabe, Eiichi Tajika, Arihiro Kamada
The present Martian climate is characterized by a cold and dry environment with a thin atmosphere of carbon dioxides (CO2). In such conditions, the planetary climate and habitabili…
Controls of Atmospheric Methane on Early Earth and Inhabited Earth-like Terrestrial Exoplanets
Aika Akahori, Yasuto Watanabe, Eiichi Tajika
Methane (CH4) is a primarily biogenic greenhouse gas. As such, it represents an essential biosignature to search for life on exoplanets. Atmospheric CH4 abundance on Earth-like inh…
A sluggish mid-Proterozoic biosphere and its effect on Earth's redox balance
Kazumi Ozaki, Christopher T. Reinhard, Eiichi Tajika
The possibility of low but nontrivial atmospheric oxygen (O2) levels during the mid-Proterozoic (between 1.8 and 0.8 billion years ago, Ga) has important ramifications for understa…
Effects of primitive photosynthesis on Earth's early climate system
Kazumi Ozaki, Eiichi Tajika, Peng K. Hong +2
The evolution of different forms of photosynthetic life has profoundly altered the activity level of the biosphere, radically reshaping the composition of Earth's oceans and atmosp…
