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 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
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
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
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 Read more
As Arctic tundra has warmed more than twice as fast as the rest of… Read more
