Accelerating Glacier Ice Loss in the Russian Arctic from Current Atmospheric and Oceanic Warming

Journal of Geophysical Research, June 30 Glaciers across the Russian Arctic are losing accelerating amounts of ice each year, especially in the western regions; where the Novaya Zemlya glaciers decreased at rates five times that of regions further east between 2010 and 2018. Novaya Zemlya currently dominates sea level rise in the Barents and Kara […]

Arctic Sea Ice Loss Far More Rapid and Extensive than Projected Using Best-fit Models

Nature Communications Earth & Environment, July 15 Model-based projections of Arctic sea ice extent have traditionally lagged behind real-world observations, in part because a large portion of global climate change models do not adequately capture specific Arctic conditions; especially ocean-atmosphere-sea ice interactions and heat transport, as well as measurements of sea ice volume (not just […]

Warm Ocean Water Accelerating Melt Rate of Langhovde Ice Shelf in East Antarctica

Nature Communications, July 9 The Langhovde ice shelf, 3 km wide is a relatively (for Antarctica) small ice shelf on East Antarctica. Measurements found that the ocean water underneath Langhovde ice shelf is warmer than the in situ freezing point of water by around half a degree or a degree, depending on the season. This […]

WAIS Collapse Not Prevented by Earth Surface Rebound Under High Emissions

Journal of Geophysical Research: Earth Surface, June 18 When an ice sheet loses mass, the pressure it exerts on the underlying Earth surface decreases, leading to a gradual bedrock uplift and an elevation gain that could potentially help stabilize the Antarctic ice sheet, slowing loss and related sea-level rise. In particular, the fast uplift rates […]

Floating River Ice Channels Correspond to Sections of Thawing Riverbed Permafrost

Frontiers Earth Science, July 6 The ice resting on top of unfrozen river water – known as “floating” or “serpentine” ice – tends to form in the deeper sections of river channels with thawed riverbed sediment. Conversely, when river water freezes all the way down to the river bottom, the ice stretches out and covers […]

Loss of Barents-Kara Sea Ice in Arctic May Cause Higher Eurasian Warming in Winter

Geophysical Research Letters, June 16 Winter sea ice loss in the Barents-Kara seas, north of Norway and western Siberia, causes local warming in the Arctic and also produces accompanying changes in atmospheric circulation. When ice loss is moderate, this leads to lower temperatures over Eurasia. However, once sea ice loss is sufficiently large and surpasses […]

Loss of Glacier Mass in Recent Years Across All of High Mountain Asia

Nature Communications, July 5 This satellite study confirms that the rate of glacier ice loss has substantially increased in seven climatically different regions, spread across the entirety of Central Asia, since the 1960s. Ice loss rates have more than doubled in the Northern Tien Shan during this time period, and have accelerated nearly as much […]

Increase in Subsurface Lakes Under the Greenland Ice Sheet

The Cryosphere, June 29 Across the entire Greenland Ice Sheet, the extent of meltwater reservoirs hidden underneath layers of packed snow and ice increased by 56% from 2018 to 2019. This increase in “buried” lakes was caused by prolonged summer surface melt in conjunction with unusually high temperatures during the autumn. In the southwest region […]

Underwater Landslides Triggered by Iceberg Collisions with the Seafloor

Nature Geoscience, June 24 Icebergs originating from the Arctic, Greenland, and Antarctica may cause hazards thousands of kilometers away from their original source by triggering underwater landslides. Four years ago, the bottom edge of an Arctic iceberg scraped against the seafloor, tipped sideways, and broke into two pieces in the Southwind Fjord of Baffin Island. […]

Decline in Permafrost Threatens the Stability of Microbial Ecosystems in Himalayas

Proceedings of the National Academy of Sciences, June 22 The thawing of permafrost has destabilized bacterial and fungal networks in the Qinghai-Tibet Plateau, reducing their connectedness and complexity by exposing them to harsh high-altitude environmental conditions. While higher temperatures normally stimulate microbial growth, temperature increases that induce permafrost degradation reduce water, oxygen, and nutrient availability […]
