Latest Ice ages Stories
Scientists find signs of 'snowball Earth' amidst early animal evolution.
Researchers evaluate climate fluctuations from 115,000 years ago.
The notion that scientists understand how changes in Earth's orbit affect climate well enough for estimating long-term natural climate trends that underlie any anthropogenic climate change is challenged by findings published this week.
In a vivid example of how a small geographic feature can have far-reaching impacts on climate, new research shows that water levels in the Bering Strait helped drive global climate patterns during ice age episodes dating back more than 100,000 years.
Global warming in this century might raise sea levels more than expected in future centuries, says a study that looked at what happened at a time when Neanderthals roamed Europe.
A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages may have been higher than previously thought.
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented.
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago.
In 2007 alone, it lost volume equivalent to draining San Francisco Bay every week.
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change.
