Greenland Ice Sheet meltwater can flow in winter, too
New findings published in Geophysical Research Letters underscore need for year-round investigations of Arctic hydrology.

Major Greenland glacier collapse 90 years ago linked to climate change
Ninety years ago there were no satellites to detect changes in Greenland’s coastal glaciers, but a new study combining historical photos with evidence from ocean sediments suggests climate change was already at work in the 1930s and led to a major collapse of the one of Greenland’s largest coastal glaciers.

New study models impact of calving on retreat of Thwaites Glacier
A new study in the AGU journal Geophysical Research Letters modeled how much faster Thwaites, one of West Antarctica’s largest and fastest-retreating glaciers, would retreat in the absence of its ice shelf — the part of the glacier that floats on top of the sea, supporting the thicker ice behind…“Worst-case scenario, it is going to be gone in less than a century. But it may also take much longer.”

Decades-old pollutants melting out of Himalayan glaciers
New research in AGU’s Journal of Geophysical Research: Atmospheres finds chemicals used in pesticides that have been accumulating in glaciers and ice sheets around the world since the 1940s are being released as Himalayan glaciers melt as a result of climate change.

Feeling Heat on the Roof of the World
The Tibetan Plateau, also known as the “roof of the world,” is getting hotter. This process is especially fast in places marked by retreating snow, according to new research.

Patagonia ice sheets thicker than previously thought, study finds
After conducting a comprehensive, seven-year survey of Patagonia, glaciologists have concluded that the ice sheets in this vast region of South America are considerably more massive than expected.

Subglacial valleys and mountain ranges discovered near South Pole
Extensive ice-penetrating radar data reveal three vast valleys under glaciers in West Antarctica. These valleys could be important in the future as they help to channel the flow of ice from the center of the continent towards the coast.

Antarctic seals can help predict ice sheet melt
Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica.

New study finds glacial evidence for abrupt climate change
Results from a new study indicate that the physical impact of abrupt climate change in Britain, Ireland and maritime Europe may be markedly different from previous perceptions of these events.

New study helps explain Greenland glaciers’ varied vulnerability to melting
Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
