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 […]
More needs to be done to better understand rapidly changing Arctic landscapes that are sinking as climate-driven permafrost thaw penetrates deeper, according to new research by University of Alaska Fairbanks scientists and others. International climate monitoring organizations have no uniform standard for measuring ground subsidence, leading to an underestimation of thaw depth and therefore an […]
Woods Hole, Mass. – The overlapping effects of sea level rise, permafrost thaw subsidence, and erosion may lead to land loss in Arctic coastal regions that dwarfs the land loss from any single one of these climate hazards, scientists say. While 75 years of aerial and satellite observations have established coastal erosion as an increasing […]
