Climatic Chain Reaction Caused Runaway Greenhouse Effect 55 Million Years Ago
There are new findings regarding a phase of rapid global greenhouse warming that took place 55 million years ago.

Warming Climate Can Support Glacial Ice: It Did In Much Warmer Times
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events

500 million years of errors: Brachiopod shells record shadow of arms race in ancient oceans
A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators

Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations

Ancient global warming drove early primates' dispersal
The continent-hopping habits of early primates have long puzzled scientists

Volcanic blast likely killed and preserved juvenile fossil plesiosaur found in Antarctica
Amid 70-mile-an-hour winds and freezing Antarctic conditions, a research team has recovered the well-preserved fossil skeleton of a juvenile plesiosaur

Study shows largest North America climate change in 65 million years
The largest climate change in central North America since the age of the dinosaurs 65 million years ago...

Predicting Pleistocene climate from vegetation in North America
Climates at the Last Glacial Maximum have been inferred from fossil pollen assemblages, but these inferred climates are colder for eastern North America than those produced by climate simulations.

Temporal response of the tiger salamander (Ambystoma tigrinum) to 3,000 years of climatic variation
Amphibians are sensitive indicators of environmental conditions and show measurable responses, such as changes in phenology, abundance and range limits to local changes in precipitation and temperature regimes.

An outer-ramp brachiopod assemblage from the uppermost San Juan Formation (middle Arenig), northern Argentine Precordillera: paleoecologic and biogeographic implications
The paper describes the brachiopod fauna recovered from the outer-ramp deposits developed at the top of the San Juan Formation in the Guandacol depocenter.

From Icehouse To Hothouse: Melting Ice And Rising Carbon Dioxide Caused Climate Shift
Three hundred million years ago, Earth's climate shifted dramatically from icehouse to hothouse, with major environmental consequences.

Greenhouse Gas Effect Consistent Over 420 Million Years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years

West African Ocean Sediment Core Links Monsoons To Global Climate Evolution
Monsoons, the life-giving, torrential rains of Asia and Africa, have an ancient, unsuspected connection to previous Ice Age climate cycles

Fossilized Midges Provide Clues To Future Climate Change
Fossilized midges have helped scientists at the University of Liverpool identify two episodes of abrupt climate change that suggest the UK climate is not as stable as previously thought.

What We Can Learn From The Biggest Extinction In The History Of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth.

Migration of Early Humans From Africa Aided By Wet Weather
The African origin of early modern humans 200,000--150,000 years ago is now well documented

Ethiopian Plateau Formation Coincided With Climate Change That May Have Spurred Human Evolution
More than three million years ago, early hominins evolved the ability to walk upright and in doing so started us along the evolutionary path that eventually gave rise to Homo sapiens.
