Presentation on Michael Gooseff, winner of the 2022 Robert L. Stearns Award, profiles his career as a polar science researcher and educator. Gooseff leads the McMurdo Dry Valleys Long-Term Ecological Research project, chairs the Water Quality Control Commission for the State of Colorado, and was a member of the Scientific Advisory Board on Water Body Connectivity for the Environmental Protection Agency among other leadership and teaching roles.

Belching lakes, mystery craters, ‘zombie fires’: How the climate crisis is transforming the Arctic permafrost (CNN)

Nov. 14, 2022

Thawing permafrost—the frozen layer of soil that has underpinned the Arctic tundra and boreal forests of Alaska, Canada and Russia for millennia—is upending the lives of people living in the Arctic and dramatically transforming the polar landscape. The vast amount of carbon stored in the permafrost is an overlooked and underestimated driver of climate crisis. Permafrost thaw gets less attention than the headline-hogging shrinking of glaciers and ice sheets, but scientists say that needs to change—fast.

Randall Duncan is an undergraduate student who is also a U.S. Army veteran. He is pursuing dual degrees in geology and geography while working with Holly Barnard on hydrology research in the critical zone. Duncan is investigating how beavers influence rivers and floodplains near Crested Butte, Colorado, funded by the NSF GEO-VETS (Geosciences-Veterans Education and Training) initiative.

Climate tipping points and the damage that could follow (NPR)

Nov. 11, 2022

If Earth heats up beyond 1.5 degrees C, the impacts don't get just slightly worse--scientists warn that abrupt changes could be triggered, with devastating impacts. As the 27th annual climate negotiations are underway in Egypt and the world is set to blow past that 1.5°C warming threshold, NPR asks climate scientists including Merritt Turetsky about three climate tipping points--points of no return that could cause big changes to the Earth's ecosystems.

Hybrids of two common North American songbirds, the black-capped and mountain chickadee, are more likely to be found in places where humans have altered the landscape, finds new research by a team including INSTAAR Scott Taylor. The study is the first to positively correlate hybridization in any species with human-caused landscape changes. It also contradicts a long-standing assumption that these two birds rarely hybridize.

New children’s book explores The Living Landscape

Oct. 10, 2022

A new children’s book is centered in the Critical Zone, the thin outer layer of Earth’s surface from the tops of the trees down to bedrock where life exists and interacts with rock, soil, water, and air. Designed for 8 to 12-year olds, the book is by INSTAARs Eric Parrish and Suzanne Anderson and is published by Muddy Boots Books.

For the past five years, a team of research assistants and volunteers have hiked up Niwot Ridge in late May to set the stage for a unique experiment in which they spread 5,000 pounds of black sand across portions of the remaining snowpack. Their goal is to simulate the near-future effects of a warming planet on alpine ecosystems.
