LOS ALAMOS, N.M., Oct. 17, 2018–A new collaborative study has investigated Arctic shrub-snow interactions to obtain a better understanding of the far north’s tundra and vast permafrost system. Incorporating extensive in situ observations, Los Alamos National Laboratory scientists tested their theories with a novel 3D computer model and confirmed that shrubs can lead to significant […]
DENALI NATIONAL PARK — When I was 12 years old, I didn’t know permafrost was like frozen lasagna. I didn’t know what permafrost was. I grew up in a small town on the Hudson River in New York. But here is my 12-year-old daughter and her classmates, gathered amid fragrant tundra plants. She is sitting […]
New NASA-funded research has discovered that Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms […]
A University of Queensland-led international study could lead to more accurate predictions or the rate of global warming from greenhouse gas emissions produced by thawing permafrost in the next 100 years. The study of the microorganisms involved in permafrost carbon degradation links changing microbial communities and biogeochemistry to the rise of greenhouse gas emissions. It […]
