Over its multibillion‐year history, the Earth has experienced a wide range of climates. The long‐term climate is controlled by the atmospheric carbon dioxide concentration, which is regulated by marine sequestration through chemical weathering. This chemical weathering sink is strongly linked to the distribution and composition of the continents. However, the effect of continental distribution has never been studied within a general framework. Here we show that the global weathering rate is… 

Insights from Simple Stochastic Models of Earth’s Long-Term Carbon Cycle and Climate

Over its multibillion-year history, Earth has exhibited a wide range of climates. Its history ranges from snowball episodes where the surface was mostly or entirely covered by ice to periods much

Simple Stochastic Modeling of Snowball Probability Throughout Earth History

Over its multibillion‐year history, Earth has exhibited a wide range of climates. Its history ranges from snowball episodes where the surface was mostly or entirely covered by ice to periods much

All aboard! Earth system investigations with the CH2O-CHOO TRAIN v1.0

. Models of the carbon cycle and climate on geologic ( > 10 4 year) timescales have improved tremendously in the last 50 years due to parallel advances in our understanding of the Earth system and



A GEOCLIM simulation of climatic and biogeochemical consequences of Pangea breakup

Large fluctuations in continental configuration occur throughout the Mesozoic. While it has long been recognized that paleogeography may potentially influence atmospheric CO2 via the continental

Long-term climate change and the geochemical cycle of carbon.

This model is stable against ice albedo catastrophe even when the ice line occurs at low latitudes, and differs from energy balance models that lack the coupling to the geochemical cycle of carbon.

Thermodynamic and Energetic Limits on Continental Silicate Weathering Strongly Impact the Climate and Habitability of Wet, Rocky Worlds

The “liquid water habitable zone” (HZ) concept is predicated on the ability of the silicate weathering feedback to stabilize climate across a wide range of instellations. However, representations of

A ‘snowball Earth’ climate triggered by continental break-up through changes in runoff

Assessment of the palaeogeographic changes preceding the Sturtian glacial period and the long-term evolution of atmospheric carbon dioxide levels using the coupled climate–geochemical model GEOCLIM indicates that tectonic changes could have triggered a progressive transition from a ‘greenhouse’ to an ‘icehouse” climate during the Neoproterozoic era.

Arc-continent collisions in the tropics set Earth’s climate state

A database of Phanerozoic arc-continent collisions and the latitudinal distribution of ice sheets was compiled, showing that ice coverage was greatest when those collisions were most widespread, maximizing global weatherability.

Hydrologic Regulation of Chemical Weathering and the Geologic Carbon Cycle

A model for silicate weathering is presented that regulates climatic and tectonic forcing through hydrologic processes and imposes a thermodynamic limit on weathering fluxes, based on the physical and chemical properties of river basins.

The impact of atmospheric and oceanic heat transports on the sea-ice-albedo instability during the Neoproterozoic

Abstract In order to simulate the climatic conditions of the Neoproterozoic, we have conducted a series of simulations with a coupled ocean–atmosphere model of intermediate complexity, CLIMBER-2,

Potential links between continental rifting, CO2 degassing and climate change through time

The concentration of CO2 in the atmosphere is a key influence on Earth’s climate. Today, significant quantities of CO2 are emitted at continental rifts, suggesting that the spatial and temporal

Emergence of the Southeast Asian islands as a driver for Neogene cooling

It is found that without the increase in area of the Southeast Asian islands over the Neogene, atmospheric pCO2 would have been significantly higher than preindustrial values, remaining above the levels necessary for initiating Northern Hemisphere ice sheets.
