Researchers find new information about 'Snowball Earth' period
It is rather difficult to imagine, but approximately 635 million years ago, ice may have covered a vast portion of our planet in an event called "Snowball Earth." According to the Snowball Earth hypothesis, the massive ice ...
Clouds could explain how Snowball Earth thawed out
Glaciation events during the Neoproterozoic (524-to-1,000 million years ago) and Paleoproterozoic (1,600-to-2,500 million years ago) periods - events that spawned ice ages that persisted for millions of years ...
Extreme climate change linked to early animal evolution
An international team of scientists, including geochemists from the University of California, Riverside, has uncovered new evidence linking extreme climate change, oxygen rise, and early animal evolution.
Interglacial on snowball Earth
Researchers from Royal Holloway, University of London have discovered that ice retreated completely through the glaciations.
The oldest evidence of bioturbation on Earth
The Ediacaran Period, an interval in Earth's history after the Snowball Earth glaciations but before the Cambrian radiations, marks the introduction of complex macroscopic organisms synchronously in unrelated groups. It has ...
What really happened prior to 'Snowball Earth'?
In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of car ...
Snowball Earth hypothesis challenged
The hypothesis that the Earth was completely covered in ice 635 million years ago has received a serious blow. The atmospheric concentration of CO2 during that period was much lower than previously thought, ...
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 ...
Life after Snowball Earth: New fossils suggest rapid recovery of life after global freeze
The first organisms to emerge after an ancient worldwide glaciation likely evolved hardy survival skills, arming themselves with tough exteriors to weather a frozen climate.
Study debunks theory on end of 'Snowball Earth' ice age
A team of scientists led by researchers from Caltech report in this week's issue of the journal Nature that the rocks on which much of a theory on how the "Snowball Earth" ice age ended was based were formed ...
Oldest fossils of large seaweeds, worm-like animals tell story of ancient oxygen
Almost 600 million years ago, before the rapid evolution of life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche near what is now Lantian, ...
Thawing a planet-sized snowball
These days the climate news is all about global warming, but global freezing was the biggest climate worry in Earth's distant past.
New evidence supports 'Snowball Earth' as trigger for early animal evolution
A team of scientists, led by biogeochemists at the University of California, Riverside, has found new evidence linking "Snowball Earth" glacial events to the rise of early animals.
Delineating primary and secondary organic carbon in neoproterozoic glacial sediments
How do we begin to understand what early life was like on Earth about 700 million years ago as our planet shifted from an oxygen-free and probably ice-covered realm to the oxygen-rich world that we know today?
