UrduAs climate change causes ocean temperatures to rise, one of Greenland’s previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.

Record low sea ice cover in the Antarctic
There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometres of the Southern Ocean were covered with sea ice.
Global warming reaches central Greenland
A temperature reconstruction from ice cores of the past 1,000 years reveals that today’s warming in central-north Greenland is surprisingly pronounced.
Desert dust collected from glacier ice helps document climate change
Researchers from The Ohio State University are using dust trapped in glacier ice in Tibet to document past changes in Earth’s intricate climate system – and maybe one day help predict future changes.
New UW Photonic Sensing Facility will use fiber-optic cables for seismic sensing, glaciology and more
A new research center is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
Study finds that landslides can have a major impact on glacier melt and movement
Using satellite imagery to study the effects of a 2019 landslide on the Amalia Glacier in Patagonia, a University of Minnesota-led research team found the landslide helped stabilize the glacier and caused it to grow by about 1,000 meters over the last three years.
15,000-year-old viruses discovered in Tibetan glacier ice
Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date.
Global warming found to be culprit for flood risk in Peruvian Andes, other glacial lakes
Human-caused warming is responsible for increasing the risk of a glacial outburst flood from Peru’s Lake Palcacocha, threatening the city below. This study is the first to directly link climate change with the risk of flooding from glacial lakes, which are growing in number and size worldwide.
