9,000-Year-Old Ice Melt: How Antarctica Could Unravel Quickly
New clues from ancient ice A recent study of 9,000-year-old Antarctic ice reveals that the continent’s ice sheets may retreat far more rapidly than earlier models suggested. The ancient melt layers indicate that warming can trigger a chain reaction, where melting in one area accelerates loss in distant regions through interconnected ocean systems. This finding…

9,000-Year-Old Ice Melt Reveals How Fast Antarctica Can Collapse
New clues from the deep past illuminate today’s risks Scientists have unearthed evidence from about 9,000 years ago that an early phase of Antarctic ice melt occurred in ways that resemble today’s rapid retreat. The findings suggest that when one region’s ice begins to melt, ocean connections can transmit that instability to neighboring areas, creating…

9,000-Year-Old Melt Reveals How Fast Antarctica Can Fall Apart
New insights from ancient ice reveal a fragile Antarctic system Researchers have traced a dramatic pattern in Antarctica’s ice history: melt events from thousands of years ago show how regional melting can quickly propagate across the continent through oceanic connections. The study, which examines geologic and climatic records from ancient ice, indicates that ice retreat…

North American Ice Sheets Triggered Most Sea-Level Rise Before 8,000–9,000 Years Ago
New Evidence Reframes the End of the Last Ice Age Groundbreaking findings published in Nature Geoscience reveal that melting ice sheets in North America played a far larger role in global sea-level rise during the final stages of the last ice age than previously thought. By examining ancient sediments and integrating a global data set,…

North American Ice Sheets Fueled End-Ice Age Sea-Level Rise
New findings rewrite the ice-melt narrative of the late last ice age Recent research led by Tulane University and published in Nature Geoscience upends decades of assumptions about how Earth’s oceans responded as the last ice age waned. The study shows that retreating North American ice sheets, not Antarctica, were the dominant driver of global…

North American Ice Sheets Triggered Most of the End-Ice-Age Sea-Level Rise, Study Finds
Breakthrough reshapes our view of last‑ice‑age sea level A Tulane University-led study has overturned long‑standing assumptions about the forces behind the dramatic global sea‑level rise that marked the end of the last ice age. The research, published in Nature Geoscience, finds that melting ice sheets in North America contributed far more to sea‑level rise between…

Canada’s CARE 2025 Expedition Makes Antarctic Data Public through Ocean Networks Canada
Canada’s CARE 2025 Expedition Delivers Open Antarctic Ocean Data Ocean Networks Canada (ONC) is releasing data from the first all-Canadian-led scientific expedition to the Antarctic, signaling a major milestone for Canadian ocean science and climate research. The Canadian Antarctic Research Expedition (CARE 2025) took place in February and March aboard the Royal Canadian Navy’s HMCS…

Greenland’s Glacier Retreat Rate Doubles in Two Decades
Introduction Greenland, the world’s largest island, is experiencing dramatic changes in its glacial landscape. A recent study by the UN’s World Meteorological Organization (WMO) reveals alarming facts about the rate of glacier retreat in Greenland, which has doubled over the past two decades. As climate change continues to accelerate, understanding these shifts is crucial for…

Greenland’s Glacier Retreat: Alarming Increases Over Two Decades
The Accelerating Retreat of Greenland’s Glaciers In a significant revelation, a recent study indicates that the retreat rate of Greenland’s peripheral glaciers has doubled over the last two decades. The data, released by the UN’s World Meteorological Organization (WMO), highlights a concerning trend. Alarmingly, five of the last six years have recorded the most rapid…

The Alarming Rate of Greenland’s Glacier Retreat
Introduction: A Glacial Crisis Greenland’s glaciers are retreating at an unprecedented rate, a phenomenon that has been documented in a recent study by the UN’s World Meteorological Organization. Over the last two decades, the rate of glacier retreat has doubled, marking a significant warning sign for climate change and its far-reaching effects on global sea…
