Winter Recreation in a Warmer World

On this week’s How on Earth, we hear from a climate scientist about the implications of our changing weather patterns for winter recreation. It’s a warm, dry winter, throughout the Rocky Mountain West and elsewhere in the country, the weather has been a mixed bag. Dr. Elizabeth Burakowski, a Research Faculty member in the Institute for the Study of Earth, Oceans and Space and Affiliate faculty in the Department of Earth Sciences at the University of New Hampshire, gives us her take. Her research focuses on winter climate change in the northeastern United States, including what changes we’ve seen in the past, what we can expect for the future, and the impacts on ecosystems and society. She is also familiar with local snowfall changes, having served on the Boulder-based non-profit Protect Our Winters since 2016.

What do Grasslands Have to do with Climate Change?

From Science MOAB

We hear an interview aired by our sister community radio station’s, Science MOAB. Ecologist Brooke Osborne talks about how dryland ecosystems – such as the grasslands east of Boulder – influence the whole planet. Dryands cover 40% of the earth; they support a third of the planet’s humans, and while their roots store lots of carbon, they’re vulnerable to climate change, overgrazing and aggressive land management.

In this episode, you’ll also hear about this weekend’s Colorado Environmental Film Festival in Golden.

Coral: Past, Present, Future

In this week’s show Beth speaks with science writer, educator, and scientist Dr. Lisa Gardiner about her recent book Reefs of Time: What Fossils Reveal about Coral Survival. Lisa studied the fossil remains of ancient coral reefs, which also suffered from environmental challenges. In our conversation, you’ll hear about how the past shapes the present, and future, of these amazing invertebrates that are keystones in ocean ecosystems. Her book describes the risks the current environment pose to these amazing organisms and the ecosystems they create, but also much much more of the significance and elegance of the corals and the reefs.

Climate Change, Astronomy, Canine Astronauts

Climate change. Astronomy.  A canine astronaut. They intersect in our guest, astronomer and author Dr. Jeff Bennett. Among other things, we focus on climate change and policy – present and future.

Dr. Bennett got his Ph.D. in Astrophysics from the University of Colorado, and he served two years as a Visiting Senior Scientist at NASA Headquarters, where he was the first scientist hired within a science division specifically to leverage science missions for education. As an author, Dr. Bennett has written college textbooks in astronomy, mathematics, statistics, and astrobiology, and a freely available, interactive digital textbook about Earth and Space Science for middle- and high-school students.  He also has written popular books that include a series for children about an intrepid astronaut dog named Max, who goes to the Moon, Mars and elsewhere.

A particular topic we plan to delve into today with Dr. Bennett is regarding his book titled: “A Global Warming Primer: Pathway to a Post-Global Warming Future”.  A current issue is the EPA’s proposal to rescind the 2009 Greenhouse Gas Endangerment Finding. The comment period for the proposed rule change has been extended to September 22. Other issues include the Department of Energy’s recent report critical of climate change research (see rebuttals of the report by Dr. Bennett and others), and whether NASA will continue doing climate and other Earth-based science.

Wildfires in a Changing Climate

On this week’s show we replay an interview from two years ago with author John Valliant on his then-newly released book, Fire Weather, the story – and much more- of the groundbreaking wildfire that devastated the oil sands capital city of Fort McMurray in Alberta. Given the current outbreaks of Colorado wildfires, getting bigger and harder to contain each year, Valiant’s message of the changing nature of these horrifying disasters is ever more pertinent. Also, headlines on the evolving nature of science in another changing climate of federal oversight.

Animal Pandemics?

On this week’s How on Earth, Beth talks with author and science journalist Liz Kalaugher, about her new book, The Elephant in the room:How to Stop Making Ourselves and Other Animals Sick. Think about it this way: When new diseases spread, news reports often focus on wildlife culprits–rodents, monkeys and mpox; bats and COVID-19; waterfowl and avian flu; or mosquitoes and Zika. But, as Liz points out, we see it often works the other way around–humans have caused diseases in other animals countless times, through travel and transport, the changes we impose on our environment, and global warming. In her deeply researched and often entertaining book, Liz introduces the wildlife we have harmed and the experts now studying the crosscurrents between humans, other animals, and health.

Wildfire Mushrooms for Wildfire Mitigation

WIldfire Mushroom c Coldfire Project

Wild, local mushrooms can break down deadwood into healthy soil, and they can do this surprisingly fast.  Used correctly, fungi are an emerging way to reduce the forest tinder that makes mega-wildfires more likely.   But there’s a wrong way and a right way to use mushrooms for mitigation  Our experts today will talk about the ways that are safe for the environment, and the results.

Our experts today are Jeff Ravage of the Coldfire Project and Zach Hedstrom of Boulder Mushroom .  They describe efforts underway to use mushrooms to break down deadwood into soil — to reduce forest tinder and also for sequestering carbon in soil.

Invasive Weed Management in Boulder County

On this week’s show Beth speaks with Joe Swanson and Laura Backus to discuss some of the invasive weeds that are plaguing Boulder County. Joe is the County Weed Coordinator for Boulder County Parks & Open Space. Joe has worked for over 17 years in rangeland and natural areas management and has been on the forefront of Boulder County Parks & Open Space natural areas invasive weed management program. Laura is a local ecologist with several decades of experience and concern in the same area. The efforts they describe are helping to restore the ecology and ecosystem function in our incredibly diverse open space lands. Photos of invasive weeds are available on the county website as is a form for reporting them.

Fire Resistant Homes

In this fire prone season, we talk with experts about an ancient building technique that might reduce the chance that a building’s going to burn. Unfired, compressed earth blocks are a building material that involves clay, sand and lime.  Our guests are architect-engineer Lisa Morey and one of her clients, Matteo Rabescini, who had such a home built in Superior, Colorado after the 2021 Marshall fire.  You can read more at Colorado Earth/Nova Terra, Heart of A Building, and Lisa Morey’s substack.
