The Arctic and Antarctic are the only places on Earth where permafrost is found. some scientists believe this frozen ground is disappearing because of climate change. Ted Schuur is an ecosystem ecologist with the Center for Ecosystems Science and Society.
Soft ticks are arachnids, like spiders. They live in pine and hardwood forests and thrive on the blood of mice, squirrels, chipmunks and sometimes birds. They don’t usually feed on humans, but, as in the case that closed Camp Colton near Flagstaff recently, it does happen once in awhile. Northern Arizona University Forest Entomology Professor Rich Hofstetter explains.
A program at Northern Arizona University encourages students to use their own life experiences to develop community projects. Students with NAU’s Campus and Community Based Action Research Teams are digging deep within themselves to recall significant events, even painful ones like domestic violence or abuse, and use them to connect with the community. Lauren Berutich is the program coordinator.
Scientists say droughts and wet periods come and go between ice ages. To understand and predict long-term climate changes, Northern Arizona University assistant research professor Nick McKay examines sediment samples from Arctic lakes.
Earthquakes can’t be predicted, but Professor Dave Brumbaugh says Northern Arizona can expect seismic activity simply because there are a number of faults here. Brumbaugh is the director of the Arizona Earthquake Information Center on the Northern Arizona University Campus. He says the Earth’s crust in the region is expanding.
Much of the carbon dioxide released into the atmosphere from human activities — like burning fossil fuel — is taken up as plant food. Northern Arizona University’s Debbie Huntzinger, a researcher of climate change models, says the land’s surface is currently storing more of the greenhouse gas than it’s giving off.
Nadine Barlow studies impact craters throughout the solar system. This professor of physics and astronomy at Northern Arizona University calls these craters nature’s drills because they tell us what’s buried beneath the surface.
When a bird flaps its wings or a seal dives into the ocean, it’s generating energy. Michael Shafer, an assistant professor in mechanical engineering at Northern Arizona University, says it’s possible to harvest the energy that an animal produces and use it to power transmitters that collect information for biologists.
Astronaut Mark Kelly says New York’s Times Square is the brightest place on Earth when looking down from space. After that, the next brightest is the Strip in Las Vegas. What may not be readily seen from space is Flagstaff, the first International Dark Sky City. That’s a designation he and his wife, former congresswoman Gabby Giffords, fully support. Kelly recently spoke on the campus of Northern Arizona University.
