Massive floods in the Mississippi River valley may have wiped out an ancient civilization, according to a new study.

Ice cores pulled from miles below Antarctica’s surface are revealing new evidence of ancient links between the climates of Earth’s Northern and Southern hemispheres.

An international team of scientists has used the 23-million-year fossil record to calculate which marine animals and ecosystems are most at risk of extinction today.

A new study may reveal an unprecedented surge in biodiversity that occurred 20 million years ago.

Climate change may be responsible for the abrupt collapse of a civilization on the fringes of the Tibetan Plateau around 2000 BC.

Just as modern nation-states struggle to manage the cultural and economic impacts of migration, ancient civilizations dealt with similar external pressures and set policies to regulate people’s movements. In one of the earliest urban societies, the Indus Civilization, mechanisms linking city populations to hinterland groups remain enigmatic in the absence of written documents. However, isotopic data from human tooth enamel associated with Harappa Phase (2600-1900 BC) cemetery burials at Harappa (Pakistan) and Farmana (India) provide individual biogeochemical life histories of migration.

It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs.

Ancient Chilean mummies that have been preserved for over 7,000 years are gradually turning into what has been referred to as "black ooze" due to climate change, reports said on Monday.

The Cauvery delta encompasses legendary farmlands for at least over the last 2300 years BP that had supported the growth of the famous Chola and Pandya kingdoms. The chrono-stratigraphic study from six sediment cores taken from the Cauvery basin indicates Holocene evolution of the present delta in response to past sea-level changes.

The collapse of the Bronze Age was not a result of climate change, as had previously been thought, scientists have confirmed.
