Are zombie fires something to worry about? As a team of scientists who have dedicated our careers to understanding changing boreal fire regimes, we decided to find out for ourselves.

CU System awards and grants to advance diversity, equity and inclusion (DEI) were also honored at an April 20 event. INSTAAR has received a grant to address inclusive open workspaces. Through participatory scenario development, ethnographic walks, and semi-structured interviews, SEEC community members will reflect on inequitable and unwelcoming spaces and conceptualize just future concepts.

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 needs to get more attention—fast.

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.

On May 3, members of the U.S. House Committee on Science, Space, and Technology and Colorado congressional delegation joined leaders and scientists from CU �鶹ӰԺ, including INSTAAR Director Merritt Turetsky, to showcase university research and federal partnerships.

Merritt Turetsky joins the For Peat's Sake podcast on Spotify to talk about permafrost peatlands. We talk about the unique qualities of permafrost peatlands and the sad reality that many of them are disappearing due to anthropogenic (aka human-caused) climate change. Merritt explains the state of the science and we also chat about mental health, the importance of self-care, and setting boundaries.

In coming decades, the shifting terrain that accompanies the warming of the permafrost caused by climate change will put most human-made structures in the Arctic at risk. Nearly 70 percent of the infrastructure in the Northern Hemisphere's permafrost regions—including at least 120,000 buildings and nearly 25,000 miles of roads—are located in areas with high potential for thaw of near-surface permafrost by 2050, according to new research. Quotes Merritt Turetsky: "I am writing a eulogy for the ecosystem that I love. The permafrost has been there for thousands of years in some places, and it will never come back."

Permafrost contains microbes, mammoths, and twice as much carbon as the atmosphere. What happens when it starts to thaw? Merritt Turetsky weighs in.

The wind-whipped firestorm that tore through parts of �鶹ӰԺ County, Colorado, on Thursday struck at the heart of one of America's top climate science and meteorology research hubs. Merritt Turetsky is among those interviewed.

A project that unites land managers, citizens, and scientists to jointly understand how Colorado Front Range ecosystems and public lands are responding to pressures from people and climate change has been funded by the National Science Foundation (NSF).
