Study Presents Large Unaccounted Carbon Footprint of Arctic Permafrost Written by AZoCleantechFeb 10 2021 The increase in global temperatures has led to the thawing of the frozen Arctic soil, or permafrost, in the northern hemisphere and the release of CO 2 stored inside it for thousands of years.

Findings of a study by an international research team, including a scientist from the University of Copenhagen among others, indicate...

In a study published in Nature Communications, Umeå University researchers and collaborators quantify carbon emissions from rivers and lakes across Western Siberia, finding that emission are high and exceed carbon export to the Arctic Ocean. High latitude regions play a key role in the global carbon cycle and climate system. An important question is the degree of mobilization and atmospheric release of vast soi...

There may be greater CO2 emissions associated with thawing Arctic permafrost than ever imagined. An international team of researchers, including one from the University of Copenhagen, has discovered that soil bacteria release CO2 previously thought to be trapped by iron. The finding presents a large new carbon footprint that is unaccounted for in current climate models.

Hiking Sweden Alone and Lost in Abisko National Park Story and photos by Madelaine Triebe After encountering a huge crowd all going in the same direction, a solo traveler back in her birthplace of Sweden takes the wrong path less traveled. I'm standing at a crossroad looking to my left and then looking to my right, realizing I have no idea of where I am. At this point exactly, on my first ever hike above the Arctic Circle, in the very north of Sweden, I'm certain I'm lost. My feet and socks are wet and so are my dark blue fake Levi's Jeans from Bangkok rolled up to my shins. The no...

Jan 25, 2021 6:41pm Paul Smith holds a doctorate in atmospheric science and works on the front lines of climate change science, collecting carbon readings from a remote site in sub-artic Sweden. One of his many jobs involves climbing a 150-meter mast to maintain an array of air quality sensors. (Paul Smith)   Obtaining carbon readings from the atmosphere in minus-30 degree Centigrade weather during mid-winter in Sweden sounds like a job for an extreme athlete. Paul Smith does that work, even though he is more of an extreme research engineer with a few athletic skills to boot. With a doctora...
