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!

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.

Science of Booze // Rosetta Mission

Booze coverProof: The Science of Booze (starts at 8:09): Science journalist Adam Rogers, who claims to have taken a liking to single-malt whiskey when he reached drinking age, has immersed himself further into alcohol–particularly, the history and science of making booze, tasting it, and enjoying–or suffering—the effects of it. Booze is a big story: Indeed, making it was a key piece of the dawn of human civilization, as Rogers, who is articles editor at Wired magazine, shows in his inaugural book, called  Proof: The Science of Booze. Rogers talks with How On Earth host Susan Moran about fascinating fungi, sugar molecules and other key ingredients, as well as our human taste buds for alcohol. We have a couple of copies of Proof from our recent pledge drive, so call KGNU (303-449-4885) this week and pledge at least $60 to get your own copy.

Rosetta’s Rendezvous (start time: 17:40): How On Earth’s own Joel Parker, whose “real” job as a planetary scientist is a director at the Southwest Research Institute, a collaborating partner on the Rosetta Mission. The mission last week successfully became the first to land a craft on a comet flying through our solar system. It was a well earned landing: Rosetta left earth in March of 2004 and has traveled about 3 billion miles to rendezvous with this moving target. To learn more, read this recent Q&A with Joel in the New York Times.

Also, Shelley Schlender offers a special headline (starts at 3:39), an interview with CU-Boulder’s Dr. Kenneth Wright, an integrative physiologist, about his new study offering new clues about why shift work can lead to extra weight.

Do Fathers Matter Pt. 2 // Mercury in Water

fathers1Do Fathers Matter? (start time: 3:07) If you’re a father or a son or daughter – which pretty much covers everyone – this interview should hit home.  Science journalist Paul Raeburn’s latest book — “Do Fathers Matter? What Science Is Telling Us About the Parent We’ve Overlooked” – explores  what seems like a no-brainer question. But the answers he discovers surprised even him. After last week’s pledge drive teaser, we now offer the extended version of host Susan Moran’s interview with Raeburn.

Mercury in Waterways (start time: 15:20) Next time you take a sip of mountain spring water or catch a wild trout, you might be getting a bit more than you bargained for. Scientists have found mercury in Colorado waterways and in the fish that swim in them. And recent research shows that wildfires in recent years may have added to the problem.  How on Earth’s Jane Palmer talked with Joe Ryan, an environmental engineering professor at the University of Colorado. Dr. Ryan also directs AirWaterGas, a project studying the impacts of oil and gas drilling on the environment.

Do Fathers Matter?

fathers1Do Fathers Matter? (start times: 9:55 and 20:58) Today’s How on Earth show is part of the KGNU fall membership pledge drive. During this show we preview an upcoming feature of the book: “Do Fathers Matter? What Science Is Telling Us About the Parent We’ve Overlooked” by science journalist Paul Raeburn.  It may seem obvious that fathers matter. And of course, they do. But just how they are affected by parenthood, and how they in turn affect their kids, is not so obvious, as Raeburn shows.  He looks at the latest research in anthropology, animal behavior, neuroscience and genetics to uncover many surprises.

Living Planet Report // Finding Exoplanet Water

WWF_LivingPlanetLiving Planet Report (starts at 5:50): The environmental organization World Wildlife Fund just released its science-based biennial Living Planet Report.  It doesn’t paint a rosy picture overall; WWF shows that, for instance, wildlife populations across the globe are roughly half the size they were 40 years ago.  And although rich countries show a 10 percent increase in biodiversity, lower-income countries are suffering a drop of nearly 60 percent. The report also ranks the ecological footprints of 152 nations, and warns that the world is living beyond its means. But there are bright spots in the report, too. Even in the absence of national legislation and international treaties, some cities in the U.S., including Boulder, and around the world are making progress toward sustainability and greenhouse gas reductions. Co-host Susan Moran interviews Keya Chatterjee, director of WWF’s renewable energy and footprint outreach program.

Finding Exoplanet Water (starts at 18:15): For the first time, scientists have detected water vapor on a cold exoplanet the size of Neptune. Previously, it had only been possible to measure the atmospheres of larger, Jupiter-sized exoplanets, but these findings from the Hubble and Spitzer Telescopes bring scientists a significant step closer to studying the atmosphere of Earth-sized planets orbiting other stars. Understanding the atmosphere of exoplanets may tell us more about their evolution and formation – Eliza Kempton, assistant professor of physics at Grinnell College in Iowa, explains in this report from Roland Pease of the BBC’s Science In Action.

The Meaning of Wilderness // The Ocean Is Us #5: Living Underwater

The Meaning of Wilderness (starts 4:30): Fifty years ago last week, President Lyndon Johnson signed into law the Wilderness Act. It was then, and remains today, one of the most significant pieces of environmental legislation. It has protected millions of acres of land. And it established a legal definition of wilderness: “an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain.” Today, many are questioning what conversation should look like hardly a square inch of land around the world is truly “untrammeled.” Co-host Susan Moran discusses wilderness then and now with Dr. M. Sanjayan, a senior scientist at Conservation International. He was a correspondent on the  Showtime series on climate change, called Years of Living Dangerously. His next  TV series, which will air next February, is called Earth — A New Wild. Dr. Sanjayan will speak this Friday at 4 pm MT at Americas Latino Eco Festival. (www.americaslatinoecofestival.org)

Living Underwater (starts 13:50): This segment continues our series, “The Ocean is Us,” exploring how we all, even in land-locked Colorado, are connected to the ocean, and what’s at stake. Co-host Susan Moran interviews Fabien Cousteau, grandson of Jacques-Yves Cousteau, the late oceanographic explorer who opened a window into the ocean for millions of people worldwide in the 1960s through his revolutionary scuba diving and underwater-living adventures. Fabien, an aquanaut, oceanographic explorer, and documentary filmmaker, discusses Mission 31, his recent 31-day underwater-living experiment (one day longer than Jacques-Yves’ expedition a half century ago).

All features in the “The Ocean Is Us“  series can be found here.  Also, check out KGNU’s year-long series on Colorado water issues. It’s called Connecting the Drops. It’s at kgnu.org and yourwatercolorado.org. To learn more or become active in preserving our watershed and the oceans, go to Colorado Ocean Coalition.
