Latest Ice core Stories
Ice samples that profile Greenland glaciers have long been used to give climate scientists historical temperature data, but those samples could be misleading.
First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years
A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent.
University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population.
There is an old trick for remembering the difference between stalactites and stalagmites in a cave:
Harvard scientists are helping to paint the fullest picture yet of how a handful of factors, particularly world-wide increases in atmospheric carbon dioxide, combined to end the last ice age approximately 20,000 to 10,000 years ago.
A new study published in the journal Nature provides evidence that rising carbon dioxide levels brought an end to the last Ice Age.
Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago?
Geoscientists at the University of Massachusetts Amherst and the University of Minnesota this week published the first evidence that warm-cold climate oscillations well known in the Northern Hemisphere over the most recent glacial period also appear as tropical rainfall variations in the Amazon Basin of South America.
