Latest Ice core Stories
A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
Norwegian explorer Roald Amundsen might have been the first person to reach the South Pole, but an international team of scientists has discovered that he was actually beaten to his destination – by industrial air pollution.
Scientists have long been concerned that global warming may push Earth's climate system across a "tipping point," where rapid melting of ice and further warming may become irreversible -- a hotly debated scenario with an unclear picture of what this point of no return may look like.
Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it?
A team of scientists from Reno, Nevada’s Desert Research Institute (DRI) led by Michael Sigl and Joe McConnell have reconstructed historic volcanic sulfate emissions from the Southern Hemisphere.
In 1889 and 2012, there was large-scale melting of the Greenland ice sheet, and a new study reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events.
A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice.
Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything—vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.
Over four decades ago, acid rain caused by industrial emissions was eradicating fish and dissolving stone monuments in the Eastern US. However, emissions of sulfur dioxide and nitrogen dioxide, both of which cause acid rain, dropped significantly after the passing of the Clean Air Act of 1970.
A glacier in Peru has been found to be shrinking as a result of warmer temperatures. Scientists have previously asserted that less snowfall was a key factor in the shrinking of this particular ice cap.
