In Alaska: Too Many Fires, Not Enough Snow “Normally a cold winter would help re-freeze the soil and slow the melting of permafrost. But the warmer air might prevent that from happening now…As things warm up, places like Alaska that have a lot of carbon stored in the soil might […]
Ecological memory stored in a landscape can help an ecosystem recover from disturbances like fire and outbreaks of disease. But what happens when climate warming disrupts that process? How long before ecological memories stored in the warming Arctic are overwritten by new ones, and what does that mean for the […]
The Center for Ecosystem Science and Society (Ecoss) at NAU has been named one of 15 new partner institutions of the AGU Bridge Program, which works to support students in applying to and succeeding in graduate school in the Earth sciences. Ecoss and the other new partner groups join a […]
The world’s oceans are getting hotter and acidifying under climate change at unprecedented rates, threatening coastal and high-mountain communities, marine ecosystems, and global fishing stocks, according to a new Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) released this week by the United Nations Intergovernmental Panel […]
Ecoss researchers show that more carbon is being released from thawed permafrost than previously thought. A new paper published this month in Nature Geoscience introduces a new way to track soil carbon in permafrost, which changes the understanding of how environmental change influences ecosystem carbon storage. The experiment builds on […]
The contemporary Arctic carbon balance is uncertain, and the potential for a permafrost carbon feedback of anywhere from 50 to 200 petagrams of carbon (Schuur et al., 2015) compromises accurate 21st-century global climate system projections. The 42-year record of atmospheric CO2 measurements at Barrow, Alaska (71.29 N, 156.79 W), reveals […]
Ecoss ecologist Ted Schuur, who’s received a $600,000 grant from the National Science Foundation (NSF) to establish a carbon observatory at Eight Mile Lake near Denali National Park in Alaska, calls the permafrost’s massive release of greenhouse gases into the Earth’s atmosphere a “wild card,” and potentially a tipping point, […]
The boreal forest is home to one-third of the Earth’s forest cover and stores 40 percent of the planet’s terrestrial carbon. North America’s boreal forest alone, which spans the northern portion of the continent from Alaska all the way to Newfoundland, covers an astounding 1.5 billion acres—more than 2.3 million […]
Ecoss professor Ted Schuur is part of a select group of scientists charged with producing a landmark report examining the effects of climate change on oceans and the frozen world and what steps people must take to reduce those effects. In July, Schuur found out that he would be one […]
