The U.S. Department of the Interior released a 1,200-page supplemental environmental impact study (EIS) on the proposed Ambler Access Road in Alaska, which reveals potentially greater social and environmental impacts than previously thought, including concerns about disrupting traditional hunting and fishing lifestyles and causing permafrost thaw.
A U.S. Energy Department climate scientist visited Utqiaġvik to evaluate research progress on permafrost and climate change, highlighting the importance of accurate measurements and models in predicting future climate patterns in the Arctic.
A research team has discovered that bottom sediment temperatures in the Russian Arctic shelf vary across different regions, with the Kara Sea having higher temperatures due to warm currents and large Siberian rivers, and the Laptev Sea and East Siberian Sea having the lowest temperatures and thicker subsea permafrost, which is important for understanding the degradation of permafrost and methane emissions in the region.
Melting permafrost will increase the maintenance costs for critical infrastructure by $15.5 billion by mid-century but unable to prevent some $21.6 billion in damages. Nearly 70% of current infrastructure located on permafrost is at risk, including major oil and gas fields, pipelines, and mines.
The Permafrost and Infrastructure Symposium this month brought together over 50 scientists, engineers and residents this month, creating a space for them to exchange their perspectives on the effects of thawing permafrost in the Arctic.
Scientists from Moscow State University have studied the Lorino cliff in the Chukotka region and discovered that the rapid retreat of the coast is due to the reduction of sea ice, and they recommend that villagers prepare for the transfer of coastal structures further inland.
The damage wrought to the park’s road by melting permafrost is creating a new reality affecting visitors, park staff, local businesses and potentially wildlife.
The Quebec government has allocated over $2 million to research and develop a plan to adapt public housing in Nunavik to the effects of thawing permafrost, which can cause damage to units built on jacks.
Scientists say that rising global temperatures are causing collapsing mountains as ancient permafrost begins to thaw.
Following a thaw slump, the water becomes cloudy and full of sediment, potentially suffocating the eggs of spawning sheefish. Scientists are concerned that permafrost thaw could lead to declines in the sheefish population, a staple food for many Alaskans.
