Down in the slumps: Tracing erosion cycles in arctic permafrost
In the Arctic, landslide-like features known as mega retrogressive thaw slumps are threatening infrastructure, altering regional biogeochemistry, and emitting carbon......»»
Warming waters of the Arctic could pose a threat to Pacific right whales
As rising global temperatures push Arctic icecaps into retreat, large and small sea creatures and the commercial fishing boats that follow them are also migrating northward......»»
Glacial rock flour creates new opportunities for Greenlandic agriculture
New research indicates that the use of glacial rock flour could enhance water absorption in cultivated fields in Greenland. This could be groundbreaking for Greenlandic agriculture as the use of glacial rock flour may reduce the risk of water erosion.....»»
Protecting polar bears is the aim of new and improved radar technology
Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers from Simon Fraser University and Brigham Young University (BYU), collaborating with Polar Bears International, hope.....»»

Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors......»»
A simulation to visualize the evolution of Alpine ice cover over the last 120,000 years
The last glacial period began around 115,000 years ago, and was punctuated by cold and warmer cycles, resulting in the advance and retreat of glaciers that shaped the landscape of the European Alps and their surroundings, carving out valleys. A new c.....»»
Apple’s environmental claims exaggerated, but company still leads others, says report
Apple’s environmental claims have again come under the microscope, just a few weeks after Greenpeace criticized the company’s annual product cycles for driving carbon emissions. While a new report also accuses Apple of exaggerating its environ.....»»
This Indigenous Community Records the Climate Change That Is Causing Their Town to Erode Away
In a tiny village north of the Arctic Circle in Canada, the Inuvialuit of Tuktoyaktuk have taken climate science into their own hands. .....»»
A Soggy Mission to Sniff Out a Greenhouse Gas "Bomb" in the High Arctic
A needle-like tower, hung with sensors, "sniffs" the air above the Arctic circle for signs of catastrophic thaw in the sodden ground below......»»
Flooding that closed Alaska"s Dalton Highway also caused widespread ground sinking
The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region......»»
Not burn-in: Scary OLED TV image retention may stem from “buggy” feature
TV compensation cycles can auto-fix the problem in minutes—assuming they run. Enlarge / Sony announced the A95K QD-OLED TV in early 2022. (credit: Sony) Image retention is scary to see on your OLED TV but often easy.....»»
Study reveals relationship between spatiotemporal variations of freezing index and permafrost degradation
The freezing index (FI) is a crucial factor for calculating the temporal and spatial distribution of permafrost and the thickness of the active layer in a permafrost region. Understanding the variation in thermal conditions of the permafrost active l.....»»
How Arctic landscapes and Canadian cityscapes share a similar pattern
The year 2023 has been one of extremes, from heat waves that baked millions across the globe and made the summer the world's hottest on record to the fires that forced tens of thousands to evacuate across Western Canada. From the feel of surprising w.....»»
Salmon are spawning in Arctic rivers, researchers confirm
Researchers have confirmed that salmon are spawning in an Arctic Ocean watershed, suggesting that at least some salmon species could be expanding to new territory as climate change reshapes their habitat......»»
Apple wants to use your mattress as a body temperature sensor
Following its Beddit aquisition, Apple has been looking at ways to use its smart mattress technology coupled with temperature sensors to identify the start of menstrual cycles, and as a measure of general health.It doesn't look like the most comforta.....»»
Ancient plant wax reveals how global warming affects methane in Arctic lakes
By studying fossils from ancient aquatic plants, Northwestern University and University of Wyoming (UW) researchers are gaining a better understanding of how methane produced in Arctic lakes might affect—and be affected by—climate change......»»
Explosion in fish biodiversity due to genetic recycling, study shows
Scientists show that the extraordinary diversity of cichlid fish in Africa's Lake Victoria was made possible by "genetic recycling"—repeated cycles of new species appearing and rapidly adapting to different roles in the ecosystem. An evolutionary c.....»»
Accounting for oxygen in modeling coastal ecosystems
Driven by climate change and pollution, the decline of oxygen levels in oceans is altering biogeochemical cycles, threatening marine plants, animals and ecosystems. But how accurately are we projecting the fate of marine life? If models of marine eco.....»»
Biological particles found to play crucial role in Arctic cloud ice formation
An international team of scientists from Sweden, Norway, Japan, and Switzerland, has presented research findings that reveal a crucial role of biological particles, including pollen, spores, and bacteria, in the formation of ice within Arctic clouds......»»
