Today’s show features: Employing Beavers (start time: 11:12): Some consider them pests. Others praise them as saviors of the environment. Whatever your impression of these furry swimming rodents, beavers are gaining more proponents for their ability to make landscapes, and thus humans, more resilient to climate change. Through their dams and lodges, beavers raise water levels, moisten fire-prone forest soil, slow water speed, and thus prevent flooding while storing more water. Host Susan Moran talks with Jessica Doran, a wildlife biologist with EcoMetrics Colorado; and Aaron Hall, senior aquatic biologist with Defenders of Wildlife, about the promises and complexities of employing beavers as ecosystem engineers.

Colorado River Basin Crisis Pt. II (start time: 6:19): This week’s How On Earth show focuses on the implications and future prospects after the federal government in June ordered the seven Western states that rely on the river to come up with a plan to save trillions of gallons of water from the shrinking river) — and after the August 15 deadline came and passed without a deal. (Here’s the Bureau of Reclamation’s news release.) How On Earth host Susan Moran interviews Aaron Citron, senior policy advisor with The Nature Conservancy’s Colorado chapter; and journalist Jerd Smith, editor of Fresh Water News. (For background, check out our July 26th show, Pt. I on the Basin’s Basin’s climate, drought, and overuse crisis. Also, see how you can make a difference by taking advantage of this recently signed legislation that helps Colorado residents convert their grass lawns into water-saving landscapes.)

This week on How On Earth: Colorado River Basin Crisis (start time: 5:31–scroll down for arrow)
The Colorado River is the life blood for about 40 million inhabitants. And it’s in dire straights. The river’s two reservoirs, Lake Mead and Lake Powell, are at historically low levels, due primarily to climate change and overuse. The water-supply crisis is affecting Colorado and six other states, as well as some 30 tribes, that rely on the Colorado River for water and electricity. Last month the federal government ordered the seven states to jointly come up with a plan to dramatically cut their consumption from the river. They have until mid-August to deliver–or they’ll face mandatory cuts. Host Susan Moran discusses with two guests the underlying causes of the water crisis, what’s at stake, and potential solutions. Jennifer Gimbel is a senior water policy scholar at the Colorado Water Center, located at Colorado State University. Formerly she was an undersecretary of the Department of Interior, and executive director of the Colorado Water Conservation Board. Tom Yulsman is a science journalist focusing on climate change. He runs the ImaGeo visual blog for Discover magazine, and he is director of the Center for Environmental Journalism at CU Boulder.

Comedy+Climate Change: (start time: 5:50) In this week’s show we look ahead to Earth Day by discussing the latest science about climate change, as reported in the recently released assessment report from the Intergovernmental Panel on Climate Change. And we explore the role that performing arts, especially comedy, can play in communicating, and processing emotions around, climate change. Our guests are Max Boykoff, a professor in, and the chair of, the Environmental Studies Department at the University of Colorado Boulder, and a contributing author of the recent IPCC report; Beth Osnes, a professor of Theatre and Environmental Studies at CU Boulder, and co-director of Inside the Greenhouse, a project at the university for creative climate communication; and Henrique Sannibale, an undergraduate student at CU Boulder studying environmental studies and business.

Heartbreak in Our Bodies: (start time: 6:58) This week on How On Earth, host Susan Moran talks with science journalist Florence Williams about her newly published book, Heartbreak: A Personal and Scientific Journey, in which she goes on a quest to understand why, and how, the heartbreak she felt when her marriage fell apart was wreaking havoc on her body. The book, and this interview, also explore various methods of healing and the science behind them.

On this week’s show journalist and author Michelle Nijhuis talks with How On Earth host Susan Moran about her recently published book, Beloved Beasts: Fighting for Life in an Age of Extinction. It’s a book of hope, history, and even humor. Special thanks to listeners who donated and received copies of the book. And thanks to WW Norton & Company for offering several copies to KGNU to help with the fund drive.

Stem cell science v. hype (start time: 00:57) Clinics offering stem cell therapies and other forms of so-called regenerative medicine are cropping up in many states, including Colorado. Practitioners of stem cells, are touting them as repairing damaged cartilage, tendons and joints, and even treating diseases such as Parkinson’s and Alzheimer’s. While the science looks promising, it seriously lags the marketing of stem cell therapies. Last year the FDA, which has yet to regulate the clinics, issued a warning about stem cell therapies. Laura Beil, a science journalist and producer of the podcast Bad Batch, recently wrote a cover article in Science News about the hype and the latest science of stem cells. She talks with host Susan Moran about her reporting. (For more info, check out this new BBC program on stem cell “hope and hype.”)
Science for the Rest of Us (start time: 16:38) At a time our own government leaders vilify science and reinvent facts, it seems as important as ever that journalists and the public at large grasp and translate scientific research. A new book, The Craft of Science Writing, offers tips on how to find credible experts (whether on the corona virus or vaccines or climate change), separate truth from spurious assertions, and make sense of scientific studies. The book is aimed at science writers, but it can be a guidepost for anyone who wants to make science more accessible. Alex Witze, a science writer who co-authored the book Island On Fire: The Extraordinary Story of a Forgotten Volcano, is a contributor to the new book. She discusses the art of decoding and appreciating science with hosts Susan Moran and Joel Parker.

Today’s show features the following interviews, by How On Earth’s Susan Moran and guest host Ted Wood.
Audubon’s Climate Watch (start time: 4:03) Starting on Jan. 14, the Audubon Society will launch a month-long citizen science program to better understand how birds are responding to climate change. This comes at a time when, according to a 2019 Audubon report, up to two-thirds of North American birds are vulnerable to extinction due to climate change. But the Climate Watch program is one of many opportunities to protect birds. Alison Holloran, executive director of Audubon Rockies, discusses the program and how you can get involved.
Conservation on the Edges (start time: 13:26) Charismatic predators like polar bears, grizzlies, and tigers, get lots of attention, and for good reason. But many lesser known species, particularly those living in extreme environments–including muskoxen, wild yaks, takins and saigas–are also important species. They have been the research focus of Joel Berger, a professor of wildlife conservation at Colorado State University. He’s also senior scientist at Wildlife Conservation Society. Berger’s latest book is Extreme Conservation: Life at the Edges of the World.
