Latest Snowball Earth Stories
A spike in ancient marine phosphorus concentrations from 750 to 635 million years ago is linked to emergence of complex life, UC Riverside researchers say.
New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period.
Scientists have found fossils which suggest that animal life appeared on Earth millions of years earlier than previously thought.
By examining 800,000-year-old polar ice, scientists increasingly are learning how the climate has changed since the last ice melt and that carbon dioxide has become more abundant in the Earth's atmosphere.
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?
For insight into what can happen when the Earth's carbon cycle is altered -- a cause and consequence of climate change -- scientists can look to an event that occurred some 720 million years ago.
Scientists find signs of 'snowball Earth' amidst early animal evolution.
New fossil findings discovered by scientists at UC Santa Barbara challenge prevailing views about the effects of "Snowball Earth" glaciations on life, according to an article in the June issue of the journal Nature Geoscience.
Scientists have once again found cause to marvel at the brilliant tenacity of life.
The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
