Sudden Collapse In Ancient Biodiversity: Was Global Warming The Culprit?

Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity.

Earth Under Global Cooling

Thirty-four-million years ago, Earth changed profoundly. What happened, and how were Earth's animals, plants, oceans, and climate affected?

Ancient Climate Change: When Palm Trees Gave Way To Spruce Trees

For climatologists, part of the challenge in predicting the future is figuring out exactly what happened during previous periods of global climate change.

Lessons From The Past: Research Examines How Past Communities Coped With Climate Change

Research led by the University of Leicester suggests people today and in future generations should look to the past in order to mitigate the worst effects of climate change

Has The Mystery Of The Antarctic Ice Sheet Been Solved?

A team of scientists travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet.

Ancient Drought And Rapid Cooling Drastically Altered Climate

Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate.

Plants Save The Earth From An Icy Doom

When glaciers advanced over much of the Earth's surface during the last ice age, what kept the planet from freezing over entirely?

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.

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

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.
