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 Journal of Geophysical Research:… Read more

Study findings take a dramatic step towards a greenhouse gas information system that can fundamentally change the way cities, states and the nation tackle the climate change problem
Results from Northern Arizona University’s Vulcan Project estimating carbon dioxide (CO2) emissions from fossil fuel combustion for the entire U.S. show very close agreement to a new atmospheric-based approach for estimating these same emissions, as reported in a paper published… Read more
If the fate of carbon is a test that planet Earth is taking right now, one of the answer keys is likely to be found in soil, where microorganisms—which account for nearly 15 percent of global biomass, by some estimates—eat, store and respire carbon and other nutrients. As Earth warms, how these microbes change the way they live will have potentially big consequences for where the carbon goes.
Now, a team led… Read more
As data centers expand to handle the exponential growth of global data traffic, the amount of energy they consume is increasing at an alarming rate. Currently, data centers use approximately 10 percent of the world’s electricity—predicted to grow to 20 percent by 2025—and in the process are also becoming one of the world’s biggest sources of pollution.
A major… Read more
The Earth’s atmosphere, oceans and biosphere are huge reservoirs of carbon, and all play a critical role in global carbon cycling. Soil is one of the largest carbon pools on the planet, storing more carbon than the atmosphere and biosphere combined, yet scientists aren’t sure what regulates carbon persistence—the amount of carbon that remains in the soil.
Scientists at the Lawrence Livermore National… Read more
