Influence of the Solar Luminosity on the Glaciations, Earthquakes and Sea Level Changes

Glaciations were attributed to variations of the Earths orbit (Milankovitch cycles). But the best ever dated paleoclimatic record (from a speleothem from Devils Hole, Nevada) demonstrated that the end of the last glacial period (termination II) happened 10 000 years before the one suggested by the orbital variations, i.e. the result appeared before the reason. This fact suggests that there is something wrong in the theory. Glaciations and deglaciations drive changes of the sea level. Changes in the speed of Earths rotation during glacial- interglacial transitions produce fracturing of the Eart…

Influence of relative sea-level rise, meteoritic water infiltration and rock weathering on giant volcanic landslides: theory and real cases

Recent studies have shown that giant landslides seem to be correlated with climatic variations. Nevertheless, the precise processes that are involved in this phenomenon need to be better constrained. In this study, the causes of giant landslides are investigated using a modeling approach. Here, we show that the effect of meteoritic water infiltration could be discriminated from that of sea-level rise on triggering paleolandslides. It is possible to identify the cause of coastal paleolandslides based on the age of occurrence and comparison with climatic signals when glacial maxima are more humi…

Millennial-scale stable oscillations between sea ice and convective deep water formation

During the last ice age there were several quasi-periodic abrupt warming events. The climatic effects of the so-called Dansgaard-Oeschger (DO) events were felt globally, although the North Atlantic experienced the largest and most abrupt temperature anomalies. Similar but weaker oscillations also took place during the interglacial period. This paper proposes an auto-oscillatory mechanism between sea ice and convective deep water formation in the north Atlantic as the source of the persistent cycles. A simple dynamical model is constructed by coupling and slightly modifying two existing models …

Consequences of glacial cycles for magmatism and carbon transport at mid-ocean ridges

Magmatism and volcanism transfer carbon from the solid Earth into the climate system. This transfer may be modulated by the glacial/interglacial cycling of water between oceans and continental ice sheets, which alters the surface loading of the solid Earth. The consequent volcanic-carbon fluctuations have been proposed as a pacing mechanism for Pleistocene glacial cycles. This mechanism is dependant on the amplitude and lag of the mid-ocean ridge response to sea-level changes. Here we develop and analyse a new model for that response, eliminating some questionable assumptions made in previous …
