A major scientific expedition to Greenland is preparing to deploy an advanced fleet of robots, drones, autonomous submarines, and sensors to study glacier melting where ice meets the ocean. The project, known as GIANT (Greenland Ice sheet to AtlaNtic Tipping points from ice loss), is funded by the United Kingdom’s Advanced Research and Invention Agency …
A new study published in Communications Earth & Environment suggests that climate change has triggered a major and potentially irreversible transformation in the chemistry of the Arctic Ocean, with significant consequences for marine ecosystems and the global climate system. Researchers have found that the rapid decline of Arctic sea ice has caused a substantial reduction …

For decades, Arctic permafrost has functioned as a massive natural storage system, effectively trapping carbon-rich organic material beneath frozen ground and slowing the release of climate-warming gases. However, new experimental research from the University of Leeds reveals that this system may be far more vulnerable than previously understood. As temperatures rise and frozen soils begin …

A new study highlights how an expanding network of meltwater lakes along the edge of the Greenland ice sheet is playing a critical role in accelerating glacier movement and intensifying global sea-level rise. Greenland has already been losing approximately 264 gigatons of ice annually since 2002, contributing about 0.8 millimeters per year to rising sea …
The first scientific results from GreenDrill, a pioneering drilling initiative led by researchers from the University at Buffalo and Columbia University, reveal that the Prudhoe Dome ice cap in northwest Greenland completely melted around 7,000 years ago—far more recently than scientists had previously believed. Published in Nature Geoscience, the study provides striking new evidence that …

Over the past several decades, the Arctic has become a clear indicator of the planet’s shifting climate. Since satellite records began in the late 1970s, scientists have documented dramatic losses in summer sea ice, with coverage halving compared to the early record. Global warming, driven primarily by human emissions, accounts for roughly two-thirds of the …
The Greenland ice sheet is melting at an unprecedented pace, losing roughly 270 billion tons of ice each year. Spanning over a million square miles and in places more than a mile thick, this massive body of ice plays a central role in regulating Earth’s climate and sea levels. The steady loss of ice directly …

A sudden and dramatic event unfolded beneath the Greenland ice sheet at Harder Glacier when a hidden subglacial lake burst, sending an explosive surge of water upward through thick ice. Over just ten days, 23.8 billion gallons (90 million cubic meters) of water—equivalent to nine hours of Niagara Falls at full flow—were released. The force …
As the Arctic warms at four times the global average, long-time glaciologist John Moore has witnessed many of his former research sites vanish. The ice that once provided stable ground for scientific inquiry has melted, prompting urgent efforts to slow or reverse the accelerating climate crisis in the region. Moore, along with the University of …

Between 2016 and 2021, researchers observed that cracks, or crevasses, at the edges of Greenland’s ice sheet grew significantly in both size and depth. This change was linked to the ice’s accelerated movement from the sheet’s center toward the ocean, a process driven by rising temperatures. This movement contributes to crevasse formation, which could set …
