Pine Beetle Kill // Plight of Sharks

“Empire of the Beetle” by Andrew Nikiforuk

Feature #1: If you live on the Front Range, or just about anywhere else in Colorado, you don’t have to go far to notice huge swaths of rusty brown that have replaced green conifer forests. By now, many people are familiar at least with the devastating effects of the mountain pine beetle. But far fewer may understand just how these voracious insects actually make their living, or that this epidemic — and its causes and triggers — are far more nuanced, and controversial, than meets the eye.  How On Earth co-host Susan Moran talks with Canadian journalist Andrew Nikiforuk about the beetles that have been gorging with impunity on lodgepole pine, spruce and other forests from British Columbia down nearly to Mexico. His new book is called The Empire of the Beetle: How Human Folly and a Tiny Bug Are Killing North America’s Great Forests.Previously, he wrote a best-selling book called Tar Sands.

“Demon Fish” by Juliet Eilperin

Feature #2:  Sharks have a special place in the human psyche.  Perhaps it is a combination of the mystery of the depths of the ocean and natural fear and awe of powerful beasts that can kill humans with a single bite.  But these predators also are key players in the ocean’s ecosystem. The science and legends of sharks are the subject of a new book called “Demon Fish: Travels Through the Hidden World of Sharks” by Juliet Eilperin, the environmental science and policy reporter for The Washington Post.  How On Earth’s Joel Parker talks with Juliet about her book. Listen to the extended interview here.

Nitrogen pollution // Electric vehicles

On today’s show we offer two interview features.
Feature #1:

Gulf of Mexico hypoxic zone, caused by excess nutrients, mainly nitrogen from fertilizer

Last week the Environmental Protection Agency published a seminal report about nitrogen, which is an enormous environmental and public health problem that some scientists put on par with the carbon imbalance. Nitrogen is essential for all life, including ours, but excess nitrogen in the environment is turning out to be a predicament of crisis proportions. It kills fish, creates “dead zones” in places like the Gulf of Mexico, contaminates drinking water, and causes human illnesses.
Co-host Susan Moran interviews Dr. Hans Paerl, who has served on the EPA science advisory board and co-authored the report.   He’s a professor of Marine and Environmental Sciences, at the UNC-Chapel Hill Institute of Marine Sciences.

Feature #2:
Our reliance on petroleum-fueled vehicles can be blamed, at least in part for a wide range of problems we face today, from local air pollution to global warming, the balance of payments deficit to political instability on a global scale.  One possible solution is to shift from a reliance on gasoline to the use of electricity for transportation.  Co-host Tom McKinnon interviews John Gartner, a senior analyst at Pike Research in Boulder, to discuss the electric vehicle outlook in the U.S.

Pluto’s Moons // Wildlife Preservation

(credit: NASA, ESA, M. Showalter, Z. Levay)”]Pluto and its moons [click to enlarge] (credit: NASA, ESA, M. Showalter, Z. Levay)Feature #1:
Last month, astronomers working on the Hubble Space Telescope announced the discovery of another, fourth moon around Pluto; this moon is so small that it could fit easily inside Boulder County (a pretty tricky thing to find at a distance of three and a half billion miles). The researchers who found the new moon were making observations in support of NASA’s New Horizons spacecraft, which is en route to fly by and study Pluto in 2015, and continue onward to explore the mysterious region beyond Pluto’s orbit known as the Kuiper Belt. How On Earth’s Ted Burnham recently met with Alan Stern, principal investigator on New Horizons, to talk about what the discovery means for that mission. [An extended version of the interview also is available.]

Feature #2:
The significant loss of species on Earth is primarily due to human destruction of habitats, forests and other wild nature, to make room for new development and agriculture. Climate change is also accelerating the rate of species extinction. Among the efforts worldwide to protect wilderness and nature so wild animals can survive is a Boulder-based nonprofit called The WILD Foundation. Harvey Locke is the organization’s vice president for conservation strategy and he helped launch the Yellowstone to Yukon Conservation Initiative (Y2Y) several years ago and oversees a global campaign called Nature Needs Half. Y2Y’s goal is to create a continuous 2,000-mile corridor for wildlife from Yellowstone National Park in the U.S. to the Yukon in Northern Canada. Harvey joins us in the studio to talk about that campaign and the science behind wildlife preservation targets.

Green Tech Author // NCAR Climate Scientist

energy comics, courtesy greentechhistory.com

This week’s How On Earth offers two features:
Co-host Susan Moran interviews Alexis Madrigal, a senior editor for The Atlantic magazine and author of the new book, Powering the Dream: The History and Promise of Green Technology. Madrigal spins tales of the bicycle boom in the 1800s and how it paved the way for cars, ironically; of a time when gasoline emerged as a waste product of kerosene for lighting; and when crude oil was what you might call the environmentally sound alternative to oil from whales, which were nearly hunted to extinction.  Madrigal also pays tribute to Colorado’s National Renewable Energy Lab and its deep history of spawning renewable energy and surviving budget cuts. And he honors green-tech (and fossil fuel) inventors and beacons of yesteryear, as he looks forward to what a greener future could be.

In the second feature, Shelley Schlender interviews Warren Washington, a ground-breaking climate scientist at the National Center of Atmospheric Research in Boulder. He’s a world leader in using computers to model climate.  Last year he was awarded the National Medal of Science by President Obama. Dr. Washington’s autobiography is  Odyssey in Climate Modeling, Global Warming, and Advising Five Presidents.

Ocean Acidification // Citizen Science

Feature #1: Many problems plague the oceans and the fish and other species that inhabit them: overfishing, pollution, and much more. But perhaps the greatest threat to sea life – and possibly to humans – is ocean acidification.  That’s when the chemistry of the ocean changes and causes seawater to become more acidic because the ocean is absorbing carbon dioxide from the atmosphere. This increase in ocean acidity makes it difficult for many plants and animals in the ocean to make or maintain their shells or skeletons.  The head of the National Oceanic and Atmospheric Administration (NOAA), Jane Lubchenco, recently said that the ocean is becoming more acidic at rates not seen for at least 20 million years, and that’s due mostly to increases in CO2 in the atmosphere.  The threat is so grave that NOAA recently created a distinct Ocean Acidification Program. In May, Dr. Libby Jewett was appointed the first director of the program. We talk with Dr. Jewett find out more about the problem and what she aims to do about it.

Feature #2: Some sciences have a tradition of fruitful interactions between professional researchers and amateurs, and this has been made even more accessible with data being able to be shared over the internet across the world.  Dr. Pamela Gay, an Astronomer at Southern Illinois University, Edwardsville, is the architect and participant in many such collaborations. In addition to her teaching and research, she does extensive public outreach to share the excitement of astronomy (such as her podcast AstronomyCast.com) and even finds ways to let anyone with an internet connection make new scientific discoveries and find new worlds that will be visited by spacecraft (IceHunters.org).  We talk with Dr. Gay about the Zooniverse and her hunt for of icy objects in the outer solar system.

Science Education, Evolution & Creationism

the book “Why Evolution Works (and Creationism Fails)" by Matt Young and Paul Strode

At its most basic level, science can be considered as non-political or at least politically neutral: science is dedicated to the collection of facts and interpreting them to help us understand the universe and how it works. For that reason, many people – one may even say our culture in general – places a high value in being scientifically literate. Or at least we pay lip service to that idea. But when the results of science end up contradicting and conflicting with other ideals such as religious beliefs, personal behaviors, or vested interests, then science can become very political. Perhaps the two most visible examples of this politicization of science are in the areas of climate change and evolution, where the discussion ranges from the White House and Congress to local school boards and textbooks. Our guest today has front line experience in several aspects of science and education. Dr. Paul Strode is a biology teacher in the Boulder Valley School District, and has been an instructor of ecology and evolutionary biology at the University of Colorado. Dr. Strode is co-author of the book: “Why Evolution Works (and Creationism Fails)” – also available and reviews here and here.

This week co-host Susan Moran speaks with Dr. Doug Kenney, director of the Western Water Policy Program at the Natural Resources Law Center at the University of Colorado,  Boulder’s law school. Kenney sheds light on the Colorado River Compact and how population growth, climate change, and water politics, are expected to further threaten our future water supply.

And Ted Burnham interviews skeptic and science writer Michael Shermer. His new book, “The Believing Brain,” presents a counter-intuitive explanation for how we form and reinforce our beliefs. Shermer draws on evidence from neuroscience, psychology and sociology to show that we often form beliefs first, and only then look for reasons to believe.
