The aquatic chemistry and flow rates in Interior Alaska’s streams are shifting in response to thawing permafrost and increased rainfall, a new study reports. The study authors found that groundwater makes up a greater portion of streamflow in areas with less permafrost. The paper, published in the June 2025 issue of Water Resources Research, was co-authored […]
Researchers developed a method that uses high-resolution satellite imagery and deep machine learning to double the mapped infrastructure of Alaska and more accurately project economic risks associated with permafrost thaw In the Arctic, permafrost plays a crucial role in building infrastructure. However, as the region warms and permafrost thaws, infrastructure is threatened as the ground […]
The Arctic permafrost thaw is hazardous to the livelihood, safety, health, food security, and the infrastructure of communities living in Arctic regions, an international group of scientists have warned. In a comparative interdisciplinary study, the scientists analyze four arctic regions, one in each of Russia, Canada, Norway and Greenland, to identify and assess the key […]
We can’t see them, but there are more microbes — tiny fungi, bacteria, worms and other living things — in a teaspoon of soil than there are people on Earth. Hungry as you and me, those microbes gobble up bits of plant and animal material. And just like you and me, soil microbes release greenhouse […]
