During the Precambrian era, Earth's decelerating rotation would have passed a 21 h period that would have been resonant with the semidiurnal atmospheric thermal tide. Near this point, the atmospheric torque would have been maximized, being comparable in magnitude but opposite in direction to the lunar torque, halting Earth's rotational deceleration, maintaining a constant day length, as detailed by Zahnle and Walker (1987). We develop a computational model to determine necessary conditions for…

A shorter Archean day-length biases interpretations of the early Earth's climate
Earth's earliest sedimentary record contains evidence that surface temperatures were similar to, or perhaps even warmer than modern. In contrast, standard Solar models suggest the Sun was 25% less
Dynamics of the Great Oxidation Event from a 3D photochemical-climate model
Abstract. From the Archean toward the Proterozoic, the Earth's atmosphere underwent a major shift from anoxic to oxic conditions, around 2.4 to 2.1 Gyr, known as the Great Oxidation Event (GOE). This
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
Astronomically forced climate change in the late Cambrian
Abstract We report evidence for Milankovitch cycles in two drill cores from the Cambro–Ordovician Alum Shale Formation of Scandinavia. The signal is preserved in elemental abundances recorded at high

Rocky Planet Rotation, Thermal Tide Resonances, and the Influence of Biological Activity
It is suggested that atmospheric oxygenation and ozone production could play a key role in planetary rotational evolution, and therefore represents a surprising but potent form of biological imprint on astronomically accessible planetary characteristics.


A constant daylength during the Precambrian era?
The history of the lunar orbit with and without a sustained resonance is integrated, finding that the impact of a sustained Resonance on the other orbital parameters of the Earth-Moon system would have not been large.
Lunar orbital evolution: A synthesis of recent results
The present rate of tidal dissipation in the Earth-Moon system is known to be anomalously high, in the sense that the implied age of the lunar orbit is only 1.5×109 years, though other evidence

Multiple causes of Earth's earliest global glaciation
In the context of Earth System evolution, the causal factors driving the Palaeoproterozoic Huronian global glaciations occupy a central position. The rise of O2 at 2320 Ma, which eliminated most of
Re-Os geochronology and coupled Os-Sr isotope constraints on the Sturtian snowball Earth
New Re-Os geochronology, together with existing U-Pb ages, reveal that the glacial period in northwest Canada lasted ∼55 My and indicates that increases in mantle-derived, juvenile material emplaced onto continents and subsequently weathered into the oceans led to enhanced consumption and sequestration of CO2 into sediments.
Earth's Variable Rotation
Investigations of more rapid fluctuations bear on meteorological studies of interannual, seasonal, and intraseasonal variations in the general circulation of the atmosphere and the response of the oceans to such variations.

Insolation absorbed by the surface of Venus is quickly redeposited at the bottom of the atmosphere. This periodic heating causes mass to flow away from the warm afternoon side of the planet and into
Paleoproterozoic snowball earth: extreme climatic and geochemical global change and its biological consequences.
Geological, geophysical, and geochemical data support a theory that Earth experienced several intervals of intense, global glaciation ("snowball Earth" conditions) during Precambrian time. This
