Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation to develop a virtual reality teaching tool called Polar Explorer. In this… Read more

New NAU study measures long-term carbon loss from thawing permafrost in Alaska
New 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
NAU global change ecologist leads NASA satellite study of rapid greening across Arctic tundra
As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a team of researchers finds the region has become greener as warmer air and soil temperatures lead to increased plant growth.
“The Arctic tundra is one of the coldest biomes on Earth, and it’s also one of the most rapidly warming,” said Logan Berner, assistant research professor with Northern Arizona… Read more
NAU researchers win $1.3M in NSF grants to study major shifts in carbon storage
Two researchers at the Center for Ecosystem Science and Society have won separate awards totaling $1.3M from the National Science Foundation to better understand where carbon is being stored and released in the terrestrial biosphere. Using different approaches, the two projects aim to better predict carbon storage by plants and soils in critical regions of the globe, and how that storage is being altered by changing climate… Read more
NAU researchers on team finding stocks of vulnerable carbon twice as high where permafrost subsidence is a factor
New research from a team including scientists of the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University suggests that subsidence—gradually sinking terrain caused by the loss of ice and soil mass in permafrost—is causing deeper thaw than previously thought and making vulnerable twice as much carbon as estimates that don’t account for this shifting ground. These findings, published this week in the
NAU scientists help chart a path to understand how Arctic vegetation is changing
As Arctic tundra has warmed more than twice as fast as the rest of… Read more
