Increasing Tsunami Risks from Antarctica Threaten South America, New Zealand, and South East Asia

Nature Communications, 18 May 2023 Microscopic fossils from millions of years ago reveal that previous warm periods 2-4°C above today’s temperatures weakened parts of the continental slope around Antarctica, triggering underwater landslides and tsunamis that could occur again in the near future if temperatures continue to rise. Glacier retreat and warm ocean waters deposit unstable […]

New Report Outlines Risks from Declines in Antarctic Sea Ice

News Briefing: 17 April 2023 Last month, the Australian Antarctic Program Partnership (AAPP) and the Australian Centre for Excellence in Antarctic Science (ACEAS) released a briefing paper for policy makers covering three unprecedented extreme low Antarctic sea ice events, all of which occurred in the past seven years. Antarctic sea ice plays a crucial role […]

COP27 Video of the Week: “Building with Nature for Climate Resilience”

This side event underscores that ice loss and subsequent sea level rise from polar ice sheets pose a far-reaching and urgent threat to communities across the world. In this session, an international team of academics, policy makers, businesses and local people come together to discuss nature-based solutions that provide vulnerable regions with costal defenses while […]

Tidal Mechanisms Could Double Rates of Sea Level Rise from Parts of Greenland and Antarctica

Proceedings of the National Academy of Sciences, 8 May 2023 Warm seawater can flow many kilometers underneath glaciers as tides periodically lift the ice off the seafloor, exposing its vulnerable underside to warm ocean waters. This newly observed ice-ocean dynamic suggests that current models may underestimate the potential rate of future sea level rise from […]

Rising Temperatures Increase Algae Growth, Glacier Loss Across North Cascades

Nature Communications, 8 May 2023 Dark red algae on snow can increase spring snowmelt by 20% in the US Pacific Northwest, jeopardizing downstream species such as salmon that depend on the stability of these frozen mountain regions for their survival. Increasingly early spring weather allows dense algae blooms to spread across the snow. Algae absorbs […]

COP27 Video of the Week: “Cross-regional Climate Impacts and Youth-led Solutions from the Arctic to Africa to the Pacific”

This panel discussion from COP27 lifts up the voices of young people, underscoring the importance of reducing emissions to slow the devastating and global impacts of cryosphere loss. Speakers explored how Arctic, African and Pacific communities can form cross-regional collaborations critical to building resilience and collectively working towards climate justice. Soomin Han, Climate Finance Lead […]

The Importance of 1.5°C for Global Economies due to Cryosphere and Other Impacts

Environmental Research Letters, 2 May 2023 This study summarizes the long-term risks and consequences associated with overshooting the 1.5°C limit of the Paris Agreement, focusing on the global impacts of rising temperatures on ice sheets, permafrost, wildfires, heatwaves, ocean acidification and more. One of their key findings: even temporarily exceeding 1.5°C will result in 10% […]

Melting Glaciers Pose Increasing Threat to Biodiversity in Mountain Ranges

Nature Ecology and Evolution, 4 May 2023 Glacier retreat across the European Alps decreases the habitat for crucial invertebrate species that live in meltwater rivers. Loss of these species could permanently reshape surrounding ecosystems, and weaken their ability to cope with future stressors. Stoneflies, midges, and flatworms play an important role in supporting larger organisms […]

Open Position: Nordic Coordinator

Virtual – Open to Qualified Applicants in Sweden For Capsule readers in Sweden: ICCI is seeking an enthusiastic Nordic Coordinator for a half-time contract position, to bring the implications of latest cryosphere science to the Swedish and Nordic communities. Work includes contacts with the scientists, non-governmental organizations, and international organizations, especially the UNFCCC and Nordic […]

Global Glaciers Account for One-Fourth of Total Sea Level Rise Since 2010

Geophysical Research Letters, 26 April 2023 Mountain glaciers worldwide have lost 2% of their ice in the past twelve years, with 90% of this loss driven by rising air temperatures. In this study, researchers used satellite radar data for the first time to create a global picture of long-term glacier changes, with detailed insights into […]

One-Century Old Black Carbon Particles from Oil, Coal Burning Found in Remote Antarctic Ice

Scientific Reports, 21 April 2023 An ice core from the Antarctic Peninsula contains fine soot particles released from oil and coal burning dating back to the 1930s, thousands of miles away from any potential source. Fossil fuel combustion, especially from inefficient burning. releases black carbon which can loft high into the atmosphere and eventually land […]

COP27 Video of the Week: “Slow Onset, Irreversible Events Beyond Adaptation: Global Stocktake, Implementation and 1.5° Ambition” with Florence Colleoni

Global impacts, especially loss and damage, caused by cryosphere feedbacks from emissions overshoot over 1.5°C will be largely permanent on human timescales, beyond adaptation limits for billions living in coastal or mountain-dependent regions. This session outlined the latest science on projected feedbacks from ice sheets and glaciers in the context of implementation timeframes, such as […]

Latest IMBIE Report: Five-fold Increase in Ice Loss from Greenland and Antarctica since the 1990s

Earth System Science Data, 20 April 2023 This week, IMBIE (the Ice Sheet Mass Balance Inter-comparison Exercise) released its third assessment report on the state of the planet’s ice sheets; in which leading cryosphere scientists, supported by the European Space Agency and NASA, consolidate all of the latest satellite data. The IMBIE assessment found that […]

Warming Atlantic Waters Threaten Previously Stable Greenland Glacier

Nature Communications, 19 April 2023 One of the previously most stable glaciers in Greenland is now retreating at an unprecedented rate, more than doubling the amount of ice it releases and flowing four times faster into the ocean since 2018. The Steenstrup glacier in southeastern Greenland was stable for decades, seemingly immune from rising temperatures, […]

Rising Temperatures, Melting Ice Jeopardize World’s Northernmost Research Station

News Briefing: 19 April 2023 Research stations high above the Arctic circle are experiencing record-breaking temperatures that make it increasingly difficult to collect snow and ice data before it melts entirely. At Ny Ålesund in the Svalbard archipelago, scientists hoping to harvest ice cores are finding glaciers saturated with pools of water, erasing hundreds to […]
