Latest Ice ages Stories
Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth's cycles of cooling and warming.
Geologists at the University of Leicester have shown that an ancient Ice Age, once regarded as a brief â€˜blipâ€™, in fact lasted for 30 million years.
Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.
In 1996, an international team of scientists led by the University of Zaragoza (UNIZAR) started to carry out a paleontological survey in the cave of El MirÃ³n. Since then they have focused on analysing the fossil remains of the bones and teeth of small vertebrates that lived in the Cantabrian region over the past 41,000 years, at the end of the Quaternary.
A new University of Florida study shows mammals change their dietary niches based on climate-driven environmental changes, contradicting a common assumption that species maintain their niches despite global warming.
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.
Earth's earliest ice age could have been caused by an atmospheric rise in oxygen reacting with methane, a greenhouse gas, a geologist in Maryland said. This singular event had a profound effect on the climate, and also on life, said Alan J.
New research from the Niels Bohr Institute indicates that there can be changes in the CO2 levels in the atmosphere that suddenly reach a critical turning point and with that trigger the dramatic climate changes.
A new study analyzing the fluctuations in sea levels during the last time Earth was between ice ages shows that oceans rose some nine feet in only decades due to collapsing ice sheets.
