Climate Change

Lakes in the Gobi Desert nurtured human life 8,000-years-ago

According to a new study published in the journal PLOS One, the Gobi Desert, now one of the driest and most forbidding places on Earth, was once a land of lakes and wetlands that sustained human life over 8,000-years-ago.

Archaeologists uncover traces of real world Ragnarök

Archaeologists have found traces of a climate disaster 1500-years-ago that might have inspired the legend of Ragnarök from Norse mythology.

Lost world discovered beneath Antarctic ice

A large-scale transcontinental river system from the Eocene era, dating back 44 to 34 million years ago, has been discovered beneath the Antarctic ice.

Study suggests Seahenge was built to control climate change

A recent study published in GeoJournal proposes that Seahenge was built to conduct rituals aimed at prolonging the summer during the extreme climatic changes of the 3rd millennium BC.

Study uncovers new evidence supporting Younger Dryas Impact Hypothesis

The Younger Dryas Impact Hypothesis (YDIH) proposes that a cometary or meteoric body exploded over the North American area sometime around 12,900-years-ago.

Ice Age Antarctic Ocean gives clue to ‘missing’ atmospheric carbon dioxide

Climate is not constant on Earth. Consider ice ages coming and going as an example. Parallel to ice age cycles, atmospheric carbon dioxide reduces during glacial periods and increases during warmer times, although modern fossil fuel-related carbon dioxide emission broke this natural cyclicity. With the proper proxy measurements, scientists can look into these past cycles to determine how exactly climate systems were naturally governed.

Increase in volcanic eruptions at the end of the ice age caused by melting ice caps and glacial erosion

The combination of erosion and melting ice caps led to a massive increase in volcanic activity at the end of the last ice age, according to new research.

Fossil fuel emissions could soon make it impossible for radiocarbon dating artefacts that are hundreds of years old

Carbon released by burning fossil fuels is diluting radioactive carbon-14 and artificially raising the radiocarbon 'age' of the atmosphere.

UA scientists find evidence of Roman period megadrought

A multi-decade drought that occurred in the 2nd century has been revealed by researchers from the University of Arizona by studying tree-rings (dendrochronology).

Unravelling causes of Ice Age extinctions

What caused the extinction of Ice Age megafauna? Was climate change responsible or human activity that caused the woolly mammoth and woolly rhinoceros to go extinct?
