Science and Politics of Mining (start time: 6:49)  On August 5 an inactive mine named Gold King, which had been leaking toxins for years, spewed more than 3 million gallons of toxic sludge into a creek that feeds into the Animus River in southwest Colorado. Its neon orange path of wastewater was shocking. But also shocking is the long history of acid mine drainage pollution and the lax regulations that allow mining companies to basically walk away from their disasters. Dr. Mark Williams, a professor of geography at CU Boulder, and an expert in mountain hydrology and hydrochemistry., has worked on remediation of several mines in the state. He speaks with How On Earth host Susan Moran about the anatomy of mines, how this disaster happened, what it suggests about the many other precarious mines in the state, and what should be done to prevent such disasters from happening.

Unprocessed Food // Bee Biodiversity

Unprocessed-book coverReal Food (start time 4:20): What we eat , and how we eat, is inextricably connected to our own health as well as the health of the planet.  Every decision we make—whether to bake a chocolate cake or buy it from Safeway or at a Farmer’s Market—is full of nuances and even contradictions. Megan Kimble is a writer who became obsessed with wondering how she could make a difference in the world by examining her eating habits. Her just-published book, called Unprocessed: My City-Dwelling Year of Reclaiming Real Food, is her personal journey into the scientific, public health, environmental and political issues related to food. Kimble will  speak tonight at the Boulder Book Store, at 7:30, and tomorrow night, July 30, at Tattered Cover in Denver, at 7:00 p.m.

The Buzz About Bees (start time 13:49): Across the United States, buzzing pollinators are key to the growth of countless flowering plants. But many bee species are also disappearing nationwide, due to pesticide use, habitat loss, and other threats.  Dr. Sam Droege is a wildlife biologist who studies this vanishing world. He heads up the U.S. Geological Survey’s Native Bee Inventory and Monitoring Lab. For several years he’s also led an effort to photograph bees — very, very close up.  Droege’s bee photos are the basis for a new book called “Bees: An Up-Close Look at Pollinators Around the World.”

Aging//and not aging

Will we be able to reverse aging some day soon?

Will we be able to reverse aging some day soon?

We talk with Dr Thomas Johnson about his long standing interest in aging and how he used a nearly microscopic worm to investigate this process. Recently, he has transitioned into using mice to identify genes influencing the aging process. Some of his findings have identified potential drugs to slow aging and keep us healthier as we live longer.

Birds v. Cats (start time 4:35): Spring is in full bloom on Colorado’s Front Range. Robins and other birds wake us up before the crack of dawn with their choruses.  This is also a time when many chicks will hatch and then fledge — a time when they are most vulnerable to predators. The biggest single threat to birds is a favorite household pet – yes, cats. Actually, feral and pet cats alike.  Dr. Amanda Rodewald, an ecologist and director of conservation science at the Cornell Lab of Ornithology at Cornell University, discusses with host Susan Moran the various threats to birds and their habitat, and how humans can be part of the solution. Spoiler alert: Keep Felix inside, at least during nesting season. For more info on how you can get involved, go to the American Bird Conservancy‘s Cats Indoors program.

Humor CodeThe Science of Humor (start time: 14:32): Have you ever laughed at something you know you shouldn’t have? Like when someone you know falls down the stairs? Dr. Peter McGraw discusses with How On Earth contributor Daniel Strain the roots of humor — why we find some things funny, and other things not. He’s a quantitative psychologist at the University of Colorado, Boulder where he heads up the Humor Research Laboratory, or HuRL. Yup, HuRL.  He’s also coauthor of the book The Humor Code: A Global Search for What Makes Things Funny. And he will be speaking this Thursday, May 21, at The Science Lounge, a monthly event at the Denver Museum of Nature and Science.

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.

StevenAmstrupPolar 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

rust-9781451691597_lgOn 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.

bc_moral_arc_coverThe 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

btu_900w_DSC07621_72ATLAS 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.

Arctic Dispatch (starts at 2:18): There is no question that the Arctic is thawing faster than anywhere on the planet, except the western Antarctic Peninsula. But there are still so many unknowns regarding how things are actually changing in different places, and to what effect. How On Earth’s Susan Moran recently attended the Arctic Frontiers conference in Tromso, Norway. Among the scientists who discussed research on how the receding and thinning ice in the Arctic will likely affect different species was  George Hunt, a research professor of biology at the University of Washington. Aili Keskitalo, an indigenous Sami from Finnmark, Norway and president of the Sami Parliament, discussed how energy projects, including windmill parks, are negatively affecting reindeer and Sami culture. Hunt and Keskitalo discussed these issues with Moran.

Wind forecasting (starts at 10:40): The wind industry in the U.S. faces several hurdles, including a technical one: discovering how the wind is going to blow near the mountains. For power systems to be reliable, operators must know when to expect the blustery gusts or when to expect a still breezeless calm day.  That means they need accurate wind forecasts.  The Department of Energy has just given a substantial grant to a coalition of organizations in Colorado to help improve wind energy forecasting in mountain and valley regions. Julie Lundquist, a professor of atmospheric and oceanic sciences at the University of Colorado, discusses the current and planned research with co-host Jane Palmer.

Climate Clues in Coral (starts at 9:02): Despite certain appearances and rumors to the contrary, global warming has not been on holiday for the past decade. But increases in temperature at the Earth’s surface have slowed down, prompting scientists to work hard to figure out why. It seems that a lot of heat that has been building up in our planet’s climate system due to greenhouse gas emissions has winded up deep in the Pacific Ocean. Why? Diane Thompson, a post-doctoral scientist at NCAR and lead author on a new study, discusses with HOE’s Tom Yulsman how a sample of coral from a remote atoll in the tropical Pacific revealed some important answers.

Tropic forests love CO2 (starts at 16:04) It’s been known for some time that tropical forests are not only rich in biodiversity, but they also absorb a lot of carbon dioxide that humans spew into the atmosphere.  But just how much greenhouse gases—namely CO2–these forests take up, say, compared with temperate and boreal forests, has been eluding researchers.  Britton Stephens, an atmospheric scientist at NCAR, discusses with HOE’s Susan Moran a new study he co-authored. It suggests that tropical forests may be absorbing far more CO2 than many scientists had previously thought.
