Two Belgian hikers who vanished in 1992 in the Weissmies region were found on the Trift Glacier after retreating ice exposed their bodies; DNA confirmed their identities and a recovery followed, as authorities note glacier melting linked to climate change is increasingly revealing long-buried remains.
A Nature Geoscience study shows Blood Falls' vivid red water originates from ancient seawater released from beneath Taylor Glacier, with genetic analysis indicating the brine hosts predominantly marine-associated microbes. The findings support the idea of a relic marine ecosystem beneath the Dry Valleys and suggest the subglacial water was trapped during past warm periods, offering a new timeline for flooding and isolation events and illustrating life's resilience in extreme polar environments.
Canada holds over two million lakes—carved by Ice Age glaciers—forming a vast water-rich landscape that challenges simple counts of the world’s lakes and shapes daily life.
A NASA-ISRO radar image of Antarctica shows a hummingbird-like silhouette: the mountaintop forms the body and deep ice crevasses create the plumage. Using NISAR’s dual-wavelength radar, scientists can see beneath snow and map ice movement, illustrating how the mission captures surface and subsurface ice features. The release comes on the one-year anniversary of NISAR’s launch, highlighting its ability to monitor glaciers, landslides, urban areas and more.
A NASA-ISRO NISAR radar image of an East Antarctic nunatak shows a vivid hummingbird-shaped pattern: the “bird” is not alive but formed by the mountain summit, glacier crevasses, and flowing ice, offering a glimpse into glacier movement beneath the surface; the data, released publicly starting July 20, highlights how radar can reveal hidden ice dynamics.
A NASA/Space.com photo from the International Space Station, taken by Jessica Meir, shows glaciers flowing down the northern Himalayas toward China's Tibetan Plateau, highlighting the scale of the range and offering insight into glacier dynamics and climate-change implications.
NASA's Earth Observatory showcases an ISS image of Tyndall Glacier in southern Chile, part of the Southern Patagonian Icefield, with icebergs drifting on Lago Geikie after recent calving. The glacier has shrunk since the Little Ice Age; Lago Geikie formed around 1940 as the ice retreated. Tyndall has lost about 2.2 km of length since Nov 2022 due to thinning and multiple calving events, including a major one in 2023. In May 2026 the front stood roughly 30–40 m above the lake, and scientists expect more iceberg production this fall as crevasses persist. Astronaut photography enables monitoring of remote glaciers like Tyndall and helps track ongoing climate-related changes.
A Curtin University–led study links Stonehenge’s Altar Stone to Caithness, Scotland, using mineral fingerprints and ice‑sheet modeling to show glaciers likely played only a limited role; the six‑ton block would have required a staged, human‑led journey across land and waterways to Salisbury Plain, highlighting coordinated Neolithic transport across regions rather than a purely glacial transfer.
Researchers propose the Altar Stone originated in northeast Scotland and was carried by glaciers as far as Dogger Bank during Britain's last Ice Age, with Neolithic people then moving it the rest of the way to Stonehenge, implying staged, highly organized cooperation rather than a direct glacial haul.
Antarctica’s Thwaites Glacier, nicknamed the Doomsday Glacier, is poised to lose its eastern ice shelf this year, removing a key stabilizing buttress and likely accelerating ice loss. A full collapse could lift global sea levels by about 26 inches (65 cm), intensifying coastal flooding even if emissions drop, and potentially triggering further instability in West Antarctica. The melt is driven by warm deep ocean water entering the region and changes in Southern Ocean winds, a process linked to human-caused climate change. While models vary on exact timing, scientists agree the glacier’s retreat will have long-term, wide-reaching consequences for sea level rise.
A new Science Advances study shows global mean sea level has risen about 2.06 mm/year since 1960 and accelerated to 3.94 mm/year from 2005–2023, with ocean warming accounting for about 43% of the rise and ice melt from glaciers (27%), Greenland (15%), and Antarctica (12%) becoming larger contributors over time; corrections to satellite data and tide gauges resolve a long-standing measurement gap, and scientists warn sea level will keep rising for centuries even if emissions stabilize.
Global sea levels are rising at an accelerating pace driven mainly by warming oceans expanding water, with glaciers and ice sheets contributing increasingly; improved satellite and tide-gauge measurements close a long-standing discrepancy between observations and known causes, and scientists warn sea levels will keep rising for centuries due to climate inertia.
A landslide in Tracy Arm Fjord, Alaska, dislodged 64 million cubic meters of rock and generated a megatsunami almost 500 meters high—the second-tallest ever recorded, after a 1958 Alaska event. Scientists link glacier melt from climate change to more frequent collapses, warn that such hazards may be increasing, and call for wider monitoring as cruise operators reassess safety around Alaska’s fjords.
A Nordic heatwave helped drive Europe’s 2025 summer into the record books, with more than 95% of the continent baking under extreme heat, 21 days above 30C in Scandinavia, record sea-surface temperatures, rapid glacier loss, and widespread wildfires, fueling calls for stronger emissions cuts and proactive climate adaptation.
A 2010 NASA Earth Observatory image shows Gee Lake bending across the snowy rim of the Barnes Ice Cap on Baffin Island, the last remnant of Canada’s ancient Laurentide Ice Sheet. The roughly 3.2-kilometer lake sits at the edge of a glacier up to 500 meters thick, where meltwater has carved grooves that appear as ridges across the ice. The Barnes Ice Cap, exposed in this scene as snow-free at the edge, dates back about 20,000 years and is shrinking like other Arctic glaciers due to warming temperatures; a 2017 study estimated most of the ice could disappear within about 300 years. The image illustrates how small melt lakes and glacial dynamics shape this ancient landscape and how the Laurentide legacy continues to influence oceans and sea-level rebound today.
