Over the past 150 years, global warming has more than undone the global cooling that occurred over the past six millennia, according to a major study published June 30 in Nature Research’s Scientific Data, “Holocene global mean surface temperature, a multi-method reconstruction approach.” The findings show that the millennial-scale global cooling began approximately 6,500 years ago when the long-term average global… 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 Journal of Geophysical Research:… Read more
Whether they explore how fungi help native grasses become established in salty soil, study how mice communicate across the high desert or monitor the health of toads in forest wetlands, students in Northern Arizona University’s Research Experience for Undergraduates (REU) program “Ecology, Genetics, and Adaptation on the Colorado Plateau” learn what it’s like to be a scientist.

One of the most challenging aspects of the COVID-19 pandemic has been the lack of testing needed to detect and trace infections—and without adequate testing, government officials do not have the data they need to make the best possible decisions in the interest of public health.
In addition to being in short supply, most tests… Read more
Disease modeling across four counties—Coconino, Navajo, Apache and Mohave—is designed to help inform public health experts and elected officials about how and when to remove physical distancing restrictions and re-open businesses and public spaces.
Joe Mihaljevic, mathematical epidemiologist and assistant professor in Northern Arizona University’s School of Informatics, Computing, and Cyber Systems (SICCS), is leading a new project to… Read more
Warming global temperatures are changing life on every continent on Earth, including Antarctica, where more microbes are moving in to territory previously covered by ice. How these microbes respond to warming offers us clues about what future Antarctica will look like and who will thrive there. Microbial ecologist and PhD candidate Alicia Purcell from the Center for Ecosystem… Read more
