Multiple proxies for paleoclimatic and paleoenvironmental change within sedimentary
sequences have been developed; but understanding their relationships and their relative …

Milankovitch cycles are quasi-periodic fluctuations in insolation forced by the variation in
Earth's astronomical parameters. The astronomically induced climate change affected the …

Mass extinction events are short-lived and characterized by catastrophic biosphere collapse
and subsequent reorganization. Their abrupt nature necessitates a similarly short-lived …

The end-Permian mass extinction was the most severe loss of marine and terrestrial biota in
the last 542 My. Understanding its cause and the controls on extinction/recovery dynamics …

The end-Permian mass extinction event (∼ 252 Mya) is associated with one of the largest
global carbon cycle perturbations in the Phanerozoic and is thought to be triggered by the …

The long-term history of the Earth–Moon system as reconstructed from the geological record
remains unclear when based on fossil growth bands and tidal laminations. A possibly more …

The Earth's geologic record of Milankovitch cycles closely tracks Solar System solutions for
the past 50 million years. Prior to 50 million years ago (Ma), however, the solutions lose …

The Cambrian is the most poorly dated period of the past 541 million years. This hampers
analysis of profound environmental and biological changes that took place during this …

In the Precambrian, reverse weathering—a process consuming oceanic silica, metal cations
and alkalinity to form marine clays—was a key control of the long-term carbon cycle …

Astronomical insolation forcing is well established as the underlying metronome of
Quaternary ice ages and Cenozoic climate changes. Yet its effects on earlier eras …
