A dusty atmosphere caused extreme global cooling

In recent Earth history, climate has varied following ~100,000 year, glacial-interglacial cycles with higher and lower temperatures and greenhouse gas concentrations. During the coldest glacial conditions, global mean temperatures ...

Climate instability over the past 720,000 years

A research group formed by 64 researchers from the National Institute of Polar Research, the University of Tokyo, and other organizations has analyzed atmospheric temperatures and dust for the past 720,000 years using an ...

Past climate linked to mammal communities in Africa today

Scientists are increasingly concerned about the impact of climate change on the world's biodiversity, and much effort has been placed into forecasting the response of species to these changes over the next century. Research ...

Ocean circulation rethink solves climate conundrum

Researchers from the University of Exeter believe they have solved one of the biggest puzzles in climate science. The new study, published in Nature Geoscience, explains the synchrony observed during glacial periods when ...

Pottery reveals Ice Age hunter-gatherers' taste for fish

Hunter-gatherers living in glacial conditions produced pots for cooking fish, according to the findings of a pioneering new study led by the University of York which reports the earliest direct evidence for the use of ceramic ...

Soyuz put in place for mission to space station

A Soyuz spacecraft atop a towering rocket was placed into launch position Monday at Russia's manned-space facility in the freezing, windswept steppes of Kazakhstan ahead of a five-month mission for three astronauts to the ...

Research shows how life might have survived 'snowball Earth'

Global glaciation likely put a chill on life on Earth hundreds of millions of years ago, but new research indicates that simple life in the form of photosynthetic algae could have survived in a narrow body of water with characteristics ...
