Future emissions from ‘country of permafrost’ significant, must be factored into global climate targets

Posted by Eliza Romero on October 17, 2022

Infographic of earth with rising levels of C02 depicted

By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution.  

But that’s only… Read more

Scientists partner with Indigenous communities to study effects of climate change and human development on Arctic caribou

Posted by Heather Tate on October 11, 2021

Project will help train the next generation of Arctic scientists in wildlife ecology, environmental informatics, natural resource management and social science

Logan Berner doing research in the field Wild caribou are the single most important land-based species for both human communities and ecosystems in the Arctic. Abundant across the polar region, these animals play an essential role both as herbivores that impact tundra vegetation and as an important source of food to… Read more

New $764K award from Dept. of Energy will help better predict fate of permafrost carbon

Posted by Heather Tate on

Christina Schaedel working on a computer As the Arctic endures another summer of record-breaking surface air temperatures, a team from NAU, led by Ecoss’ assistant research professor Christina Schädel, has been awarded a three-year, $764,000 grant from the Department of Energy to help improve models that predict what will happen to permafrost carbon as the Arctic continues to warm. The team, which includes Ecoss Regent’s Professor Ted Schuur, School of… Read more

New NAU study measures long-term carbon loss from thawing permafrost in Alaska

Posted by Heather Tate on May 6, 2021

Ted Schuur workin in labNew long-term data from a permafrost monitoring site in Healy, Alaska, suggest it was a net carbon source to the atmosphere at least since 2004 and, under current climate conditions as the region grows warmer, will continue to be one, potentially losing up to a fifth of all carbon stored… Read more
