Future emissions from ‘country of permafrost’ significant

October 19, 2022530 Views

Greenhouse gases emitting from Arctic must be factored into global climate targets 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 one possible future for the vast stores of carbon locked in the formerly perennially frozen but now-thawing ground in the Arctic. Using more than a decade of synthesis science and region-based models, a new study led by Northern Arizona University and the international Permafrost Carbon Network and published in Annual Review of Environment and Resources forecasts cumulative emissions from this “country of permafrost” through 2...

New research from Northern Arizona University shows rising temperatures are causing Earth’s coldest forests to shift northward, raising concerns about biodiversity, an increased risk of wildfires and mounting impacts of climate change on northern communities. Logan Berner, assistant research professor in the School of Informatics, Computing, and Cyber Systems (SICCS) and Scott Goetz, Regents’ professor and director of the GEODE Lab, authored the article, “Satellite observations document trends consistent with a boreal forest biome shift,” which was published Thursday in Global Change Biology. The boreal forest is a belt of cold-tolerant conifer trees that stretches nearly 9,000 miles across northern North American and Eurasia; it accounts for almost a quarter of the Earth’s forest area...
