The Sixth Mass Extinction: fact, fiction or speculation?
There have been five Mass Extinction events in the history of Earth's biodiversity, all caused
by dramatic but natural phenomena. It has been claimed that the Sixth Mass Extinction may …

Mantle plumes and their role in Earth processes
The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

An astronomically dated record of Earth's climate and its predictability over the last 66 million years
Much of our understanding of Earth's past climate comes from the measurement of oxygen
and carbon isotope variations in deep-sea benthic foraminifera. Yet, long intervals in …

Extinction at the end-Cretaceous and the origin of modern Neotropical rainforests
MR Carvalho, C Jaramillo, F de la Parra… - Science, 2021 - science.org
The end-Cretaceous event was catastrophic for terrestrial communities worldwide, yet its
long-lasting effect on tropical forests remains largely unknown. We quantified plant …

Asteroid impact, not volcanism, caused the end-Cretaceous dinosaur extinction
AA Chiarenza, A Farnsworth… - Proceedings of the …, 2020 - National Acad Sciences
The Cretaceous/Paleogene mass extinction, 66 Ma, included the demise of non-avian

Venusian habitable climate scenarios: Modeling Venus through time and applications to slowly rotating Venus‐like exoplanets
MJ Way, AD Del Genio - Journal of Geophysical Research …, 2020 - Wiley Online Library
One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

The Chicxulub impact and its environmental consequences
The extinction of the dinosaurs and around three-quarters of all living species was almost
certainly caused by a large asteroid impact 66 million years ago. Seismic data acquired …

Recurring volcanic winters during the latest Cretaceous: Sulfur and fluorine budgets of Deccan Traps lavas
Two events share the stage as main drivers of the Cretaceous-Paleogene mass extinction—
Deccan Traps volcanism, and an asteroid impact recorded by the Chicxulub crater. We …

Fossil biomolecules reveal an avian metabolism in the ancestral dinosaur
Birds and mammals independently evolved the highest metabolic rates among living
animals. Their metabolism generates heat that enables active thermoregulation, shaping the …
