Abstract. We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the combined ocean and atmosphere reservoir. The model is specified by introducing three different types of biosphere: procaryotes, eucaryotes, and complex multicellular life. During the entire existence of the biosphere procaryotes are always present. 2 Gyr ago eucaryotic life first appears. The emergence of…

Climate Change 2: Long-Term Dynamics

The end of life on Earth is not the end of the world: converging to an estimate of life span of the biosphere?

Abstract Environmental conditions have changed in the past of our planet but were not hostile enough to extinguish life. In the future, an aged Earth and a more luminous Sun may lead to harsh or even

The future lifespan of Earth’s oxygenated atmosphere

Earth’s modern atmosphere is highly oxygenated and is a remotely detectable signal of its surface biosphere. However, the lifespan of oxygen-based biosignatures in Earth’s atmosphere remains

Possible patterns of marine primary productivity during the Great Ordovician Biodiversification Event

Following the appearance of numerous animal phyla during the ‘Cambrian Explosion’, the ‘Great Ordovician Biodiversification Event’ (GOBE) records their rapid diversification at the lower taxonomic

What Future for the Anthropocene? A Biophysical Interpretation

The Anthropocene is a proposed time subdivision of the earth’s history correlated with the strong perturbation of the ecosystem created by human activity. Much debate is ongoing about what date

What future for the Anthropocene? A biophysical perspective

The Anthropocene is a proposed time subdivision of the earth's history correlated to the strong human perturbation of the ecosystem. Much debate is ongoing about what date should be considered as the

The Venus Life Equation.

Ancient Venus and Earth may have been similar in crucial ways for the development of life, such as liquid water oceans, land-ocean interfaces, favorable chemical ingredients, and energy pathways. If

Ecocentrism and Biosphere Life Extension

The biosphere represents the global sum of all ecosystems. According to a prominent view in environmental ethics, ecocentrism, these ecosystems matter for their own sake, and not only because they

Reduction of biosphere life span as a consequence of geodynamics

The long-term co-evolution of the geosphere’biospere complex from the Proterozoic up to 1.5 billion years into the planet’s future is investigated using a conceptual earth system model including the

Life span of the biosphere

There has been life on Earth for at least 3,500 Myr but the assumption that a comparable future lies ahead may not be justified. Main sequence stars appear to increase their burning rate as they age.

Biotic feedback extends the life span of the biosphere

The Sun is becoming more luminous with time and will eventually overheat the biosphere. However, life cools the Earth by amplifying the rate of silicate rock weathering and maintaining a low level of

The life span of the biosphere revisited

A more elaborate model that includes a more accurate treatment of the greenhouse effect of CO2, a biologically mediated weathering parameterization, and the realization that C4 photosynthesis can persist to much lower concentrations of atmospheric CO2 is found to find that a C4-plant-based biosphere could survive for at least another 0.9 Gyr to 1.5 Gyr after the present time.

Cambrian explosion triggered by geosphere‐biosphere feedbacks

A new hypothesis for the cause of the Cambrian explosion is presented. For that the evolution of the planet Earth is described by the co‐evolution of the geosphere‐biosphere system. Here we specify

The results suggest that mid-to-early K stars should be considered along with G stars as optimal candidates in the search for extraterrestrial life.
