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.

Ancestors in Our Genome

We speak with Eugene Harris, Professor in the Department of Biological Sciences and Geology at Queensborough Community College – part of the City University of New York – about his new book, Ancestors in Our Genome. In this feature, we discussed the methods used by molecular anthropologists to determine human evolution from our primate ancestors and several fascinating examples of the application of these techniques, including a discussion of the rise of lactose digestion in northern Europeans.

War of the Whales: A True Story

War of the Whales: A True Story (starts at 3:35): In the early hours of March 15th, of the year 2000, a Cuvier beaked whale washed ashore a mere 100 feet from Ken Balcomb’s house on the island of Abaco in the Bahamas. It was, for the whale, a fortuitous coincidence: Balcomb was a marine mammal researcher who was uniquely placed to rescue the creature. But that day 17 more whales of various species washed up on nearby islands and some of them weren’t quite so fortunate. The event was the largest mass stranding in recent history but what might have caused it was a total mystery. To Balcomb, it was a mystery that cried out for a solution.

So begins the book “War of the Whales: A true story.” It’s a book that has been described by critics as a tense, page turning eco-thriller, even though it is a work of non-fiction. How On Earth’s Jane Palmer talks with author Joshua Horwitz about what happened after Ken Balcomb’s discovery, and the attempts to solve the mystery.

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.

Other Rocky Planets are Common!

We talk with astronomer Travis Metcalfe about finding the oldest known planetary system in the Galaxy, and what it means about the formation of planets, the possibilities of extraterrestrial life, and how does one actually find planets around other stars? Headlines include switches in the man-made biological organisms that could possibly be used for bioterrorism, and the finding that chronic malaria infection in migrant great reed warblers damages telomeres, shortening life in both the adult bird and its offspring.

The Rightful Place of Science: Disasters and Climate Change

The rightful place of science (starts at 6:22): In 2014, the world certainly saw more than a few costly weather disasters. Flooding in India and Pakistan in September killed more than 600 people and resulted in economic losses of more than $18 billion. Super Typhoon Rammasum, which hit the Philippines, China and Vietnam in July caused more than 200 deaths and losses of $6.5 billion. And, closer to home, in August, rainfall and flooding in Detroit, Baltimore and Long Island damaged homes and cities leading to economic losses of about $2 billion.

At the same time, the United Nations Weather Agency states that 2014 was the warmest year on record. So, the question is: Are these natural disasters related to the warming climate? And are natural disasters becoming more costly because of climate change?

These are questions that Roger Pielke Jr., an environmental sciences professor at the University of Colorado, addresses in his new book “The Rightful Place of Science: Disasters and Climate Change.” He talks with HOE’s Jane Palmer about his book and why he believes it is important to maintain scientific integrity while engaging in the climate debate.
