Sage Grouse Saga (start time: 4:04): One of the most spectacular and flamboyant rites of spring is, arguably, the mating ritual of a the greater sage grouse, a chicken-like bird with a long tail, with spiky tail feathers. Its historic range spans 11 Western states, including Colorado. But that sagebrush-dominated habitat has been chopped up and degraded by oil and gas development, mining operations, cattle grazing and even wind farms–causing grouse populations to plunge. Since 2010 the bird has waited for a milestone decision, due by Sept. 30, by the U.S. Fish & Wildlife Service to list it as threatened or endangered. Biologist Noreen Walsh, director of the Service’s Mountain-Prairie Region, discusses with How On Earth host Susan Moran the biology of this curious bird and a range-wide collaborative conservation initiative aimed at preserving the grouse and its habitat. Oh, check out this live “lek-cam,” from The Nature Conservancy.

Fragile Ocean (start time: 17:21) David Helvarg, a journalist and author of several books focusing on the ocean—its magnificent and imperiled creatures–discusses his books Saved By the Sea: Hope, Heartbreak and Wonder in the Blue World, and 50 Ways To Save the Ocean. Founder and executive director of Blue Frontier Campaign, Helvarg shows how residents of land-locked Colorado depend on and affect the ocean. He will speaking in Boulder this Thursday, April 30, at 6:30 p.m. at Ocean First Divers. It’s a “Blue Drinks” event put on by the Boulder-based nonprofit, Colorado Ocean Coalition.

Are Ketones the Key?

Ketones (start time 6:40) A growing body of scientific research demonstrates health benefits for many people with a diet that’s lower in carbohydrates, and higher in fats. In fact, some of this research indicates great therapeutic benefits,. One reason why may be that, when carbohydrate consumption is low enough, the body enters a state of “nutritional ketosis,” where it transforms fats into a molecule called, beta-hydroxy-butyrate, or “ketones”. In the absence of sugar and carbs, the body can use ketones as its primary fuel.

One of the scientists who has pioneered research into nutritional ketosis is Dr. Steve Phinney, and one of the populations who he believes gets special benefits from a ketone-producing diet is endurance athletes. For 30 years, Phinney has studied nutritional ketosis and athletic performance — including performance among bicycle racers, the winners of 100-mile ultra-marathons, and recently, a two-person rowing team that was among the top finishers in a rowing race that went from California to the Hawaiian Islands – rowing the whole way on a very low-carb, high fat, ketone-producing diet.

Biomimicry: A New lens on Technology and Innovation

Today’s special edition of How on Earth, brought to you in conjunction with this week’s Conference on World Affairs is a conversation on Biomimicy as a new lens to view science and technology with Margo Farnsworth.

Margo has coached two Top Twelve graduate teams for the International Student Biomimicry Challenge and currently serves as a Biomimicry Institute education fellow. She is also on the board of both the Missouri Prairie Foundation and South Carolina’s Experience Green. She has worked as a park ranger, science teacher, and mammalogist. With degrees in science education and parks administration, her professional accomplishments include research in environmental education, qualitative mammal studies, and involvement in numerous local and state environmental boards and committees. Farnsworth has written pieces for the Center for Humans and Nature as well as Treehugger, and has two biomimicry book projects pending. She joins us live for an in-depth talk about how Biomimicry has the potential for changing scientific culture.

Island On Fire: The Story of Laki

Island on Fire (04:45): In 1783, a crack opened up in the Earth, began to spew out lava and ash and poisonous gases, and didn’t stop for eight months. The volcano was Laki, one of many volcanoes in Iceland, and the effects of the eruption went global. Laki’s story is one of geology, chemistry, atmospheric science, and biology. Co-host Beth Bartel talks with long-time science writers and co-authors Alexandra Witze and Jeff Kanipe about what we’ve learned from Laki and how we can apply the lessons of Laki today.

For more on the book, check out the Island on Fire website.

Polar Bears // Climate Scientists

Climate Scientists (starts at 1:00): Climate scientists (scientists in general) tend to steer clear of speaking out as activists about concerns that are politically volatile. But that’s changing. Many climate scientists are stepping out of their research comfort zone to offer personal stories of why they care and what we all can do about the crisis. A group of scientists launched a video campaign last week. It’s called More Than Scientists. We speak with Dr. Josh Lawler (University of Washington), who one of the founders of the campaign.

Polar Bears (starts at 6:30): It is well known that, right now, life for polar bears looks bleak. Warming temperatures mean the season for sea ice cover in the Arctic has become shorter and shorter. As sea ice provides a home and hunting ground for polar bears, both the number of bears and their health has suffered. There is even talk of them becoming extinct. But is this something that we should worry about in Colorado and other non-arctic regions around the world? We don’t have bears, right now we don’t have ice, and we have plenty of other concerns. Dr. Steven Amstrup, the Chief scientist for Polar Bears International, joins us on How on Earth to explain why we should care. He thinks that polar bears are the sentinels of global health and that they provide advance warning of some of the challenges coming to all species. That includes us humans. But he thinks if we act soon, we can save both the bears and ourselves.

Dr. Amstrup also will be giving a talk in the Old Main auditorium on the CU Boulder campus on Friday, April 3rd at 4:00 pm. His talk is titled: “Why Should We Care About Polar Bears?” More details about the talk can be found at:

Rust: The Longest War // The Moral Arc

On today’s spring pledge-drive show we offer segments of two feature interviews. See extended versions also below. Both books are available to those who pledge at least $60 to KGNU. Call 303.449.4885 today.

Rust: The Longest War (start time: 4:25) It is arguably the most destructive natural disaster in the modern world. And it’s the topic of local journalist Jonathan Waldman’s debut book, which has just been published. It’s called Rust: The Longest War. Jonathan talks with How On Earth host Susan Moran about the book, which included fascinating tales of the “smart pig” that inspects the Alaska pipeline, as well as Ball Corp’s Can School in Golden, Colo. Catch Jonathan tonight 7:30 at the Boulder Book Store.

The Moral Arc (start time: 13:21) Author and renowned skeptic Michael Shermer talks with How On Earth contributor Shelley Schlender about his The Moral Arc: How Science and Reason Lead Humanity toward Truth, Justice, and Freedom. The book addresses a wide range of modern issues, including just how science and reasons can help to pave the way toward further reductions in nuclear warheads, toward greater equality for people with different gender and sexual orientations, and toward the abolishment of the death penalty. That’s pretty optimistic for the nation’s best known skeptic!

The ATLAS Institute // Firefighters and Climate Change

ATLAS Institute Today we are joined in the studio with Mark Gross of the Alliance for Technology, Learning and Society institute at CU and Alicia Gibb Director of The Blow Things Up Lab, one of the spaces part of the ATLAS department.
ATLAS was formed in 1997 as a university wide initiative to integrate information technology into social endeavour.

Firefighters and Climate Change Snowy frigid weather here in February may put wildfires way on the back burner for many of us here in Colorado. But as fire managers have been telling us, wildfire season has become a year-round phenomenon.

In the last decade or so wildfires have been getting more intense, and more dangerous, and more frequent. No one knows this better than the firefighters themselves. Climate change—making the region hotter and drier—has a lot to do with it. But so does fire management—namely, fire suppression over recent decades. And humans living in houses in the so-called wildland-urban interface is another culprit. A new documentary that will be screened in Boulder this week documents the changes taking place with wildfires and the impact they’re having. The film is called “Unacceptable Risk: Firefighters on the Front Lines of Climate Change.” One of the film’s creators, journalist Dan Glick, joins us in the studio. Dan was also the science editor of the National Climate Assessment that came out last year. Our other guest is Don Whittemore, a long-time firefighter. He was incident commander on the massive Fourmile Canyon Fire of September 2010.

More about the film can be found at unacceptableriskfilm.org.
