Haitian Seismologists//Changing Antarctic Climate

Roby Douilly and Steeve Symithe

Feature #1: (start time: 06:03) On January 12, 2010, just over three years ago, a magnitude 7 earthquake shook Haiti, taking more than 200,000 lives and displacing an estimated 2 million. Still today, the International Organization for Migration estimates hundreds of thousands of people are without permanent homes, and in many ways Haiti seems no closer to rebuilding than it did three years ago.  Co-host Beth Bartel speaks to Haiti’s first seismologists — Roby Douilly and Steeve Symithe, both graduate students at Purdue University — about the future of Haiti and a career in seismology there

Feature #2: (start time: 15:42) You’ve probably heard by now that 2012 was the warmest ever in the U.S.  We’re not the only ones overheating. At the bottom of the world, over the last 50 years, West Antarctica has warmed more than scientists had thought. The implications are huge; an enormous ice sheet there  may be at risk of long-term collapse, which could cause sea levels to rise alarmingly.  Co-host Susan Moran speaks with Andrew Monaghan, a climate scientist at the National Center for Atmospheric Research, or NCAR, here in Boulder. Dr. Monaghan co-authored the study, which was recently published in the journal Nature Geoscience.

State Climatologist // Water Contamination

Nolan Doesken

Feature #1: (start time 5:09)  Did you know that Colorado, and for that matter most states, have their own “state climatologist” – an expert who keeps tabs on the changing climate and its impacts in the state. In Colorado’s case it’s Nolan Doesken. He’s based out of the Colorado Climate Center at Colorado State University. Mr. Doesken also heads a nationwide citizen-science project called the  Community Collaborative Rain, Hail and Snow Network. How On Earth co-host Susan Moran interviews Mr. Doesken about the network, as well as a recently released Colorado River Basin Water Supply & Demand Study, which suggests we’ll be thirstier and thirstier in the future.

Feature #2: (start time 16:00) Water is such an essential — perhaps the essential — resource for life that it is considered as a key ingredient for life anywhere in the universe. No surprise, then, that it has become a battleground, especially in the Western states like Colorado that are dealing with drought conditions and higher demand for clean water to support a ever-increasing population. Dr. Mark Williams, professor of geography at CU Boulder talks with co-host Joel Parker about his research into the environmental and human health impacts of energy development and mining on the quality of water in our aquifers.

Clean Tech Nation//Feedback in Climate Models

Clean Tech Nation (start time: 4:57): Over the last few years renewable electricity generation has doubled, thanks in part to President Obama’s 2009 stimulus package. In fact, many clean technologies and industries have taken off, including solar, biofuels, green building and electric vehicles. But the stimulus money is about to run out, as is the production tax credit for wind development. To make sense of the current status of and future prospects for clean tech, co-host Susan Moran interviews Clint Wilder, co-author (along with Ron Pernick,) Clean Tech Nation: How the U.S. Can Lead in the New Global Economy.

Wilder and Pernick run Clean Edge, a clean-tech research and advisory firm.

Dr. William Hay of the University of Colorado in Boulder.
Feedback in Climate Models (start time: 14:00): We are witnesses to unprecedented changes to the earth. Great storms and melting ice caps. Scientists say these events are related to the carbon we are dumping into the atmosphere. But even the scientists are stunned by the speed and scale of melting sea ice and ice caps and sea-level rise. Dr. Bill Hay, professor emeritus of geology at CU-Boulder, talks with us about why scientists haven’t been able to keep up with mother nature.

The Dust Bowl / Population Growth

Feature #1: The Dust Bowl (start time 6:53)

As bad as the drought has been recently in Colorado and other states, it pales in comparison to the nearly 10-year-long drought of the 1930s. Its unrelenting and gargantuan dust storms inspired the name “The Dust Bowl.” In southeast Colorado and other Great Plains states, children died of dust pneumonia. Thousands of cattle died or were slaughtered. Hundreds of thousands of people were forced to flee their homes. It came to be called “the worst man-made ecological disaster in American history.” On November 18th and 19th PBS will air a four-hour documentary called “The Dust Bowl.” It was directed by Ken Burns and written and co-produced by author Dayton Duncan. How On Earth co-host Susan Moran talks with Duncan about the film and the lessons learned –or not learned — from The Dust Bowl.

Feature #2: Zero Population (start time 15:58)  John Seager, CEO of the nonprofit Population Connection, discusses with How On Earth co-host Ted Burnham about the organization’s efforts to help American citizens and politicians understand the environmental and other implications of the ever-expanding global human population. John will speak this Friday at the CU campus in Boulder. His presentation is titled, “Soaring Past 7 Billion: Population Challenges for a Crowded World.”

The Life and Legacy of Rachel Carson

The Life and Legacy of Rachel Carson (start time 6:20). The book Silent Spring, published in 1962, is widely credited for setting the stage for the modern environmental movement. Its author, Rachel Carson, an unassuming field biologist and writer, uncovered how in the process of killing crop pests, chemicals such as DDT were also killing birds, fish and other wildlife.  Fifty years after Silent Spring was published, several of the worst offending toxins are off the market – at least in the U.S. – but many more persist and new ones have emerged. And they’re wreaking havoc on human health, not just wildlife. How On Earth co-host Susan Moran talks with William Souder, author of the new book On a Farther Shore: The Life and Legacy of Rachel Carson, which was just published last month to mark the 50th anniversary of the release of Silent Spring.

Neanderthals//Antarctica


Feature #1: Neanderthals (start time: 6:01)
Our Neanderthal ancestors have long been maligned as rather dim-witted cave-dwellers. But they may have been brighter — and more colorful — more like us, shall we say.  We turn to the BBC’s Science in Action for a look at new research into who these ancestors really were. Here’s BBC’s Jon Stewart.

Feature #2: Antarctica (start time: 11:03)
It may be hard for people living in Colorado and other land-locked states to grasp that our daily lifestyles – burning fossil fuels every time we turn on the lights or drive our car, for instance – affects the delicate marine ecosystems of the Southern Ocean, from the ice algae to the penguins and whales. And in turn, the health of the plants and animals, and indeed the ice they depend on, in Antarctica, affects our own health.  Cohost Susan Moran interviews Dr. James McClintock, a marine biologist at the University of Alabama in Birmingham, about his new book, “Lost Antarctica: Adventures in a Disappearing Land.” He shares his adventures waaayy down under, and his concerns about the future of the fragile and stunning continent.

Colorado Drought // A More Perfect Heaven

A More Perfect Heaven: How Copernicus Revolutionized The Cosmos, by Dava Sobel

Colorado Drought Conference (start time 4:35): Experts are meeting at a conference in Denver this week to discuss the implications of prolonged drought conditions here in Colorado. How On Earth’ Susan Moran speaks with biologist Dr. Chad McNutt of the NOAA’s National Integrated Drought Information Center about wthe drought means for the ecosystem, and for Western cities — and how we can start to address the problem.

A More Perfect Heaven (start time 11:50): Joel Parker speaks with Dava Sobel, a science journalist and author who tells the stories of the science and the scientists from the past and how they connect to the present. Those stories reveal that the course of scientific progress is far from orderly — it often takes unplanned twists, has failures that require going back and starting over, and can be driven by the quirks of the personalities of individual scientists.

Today we hear about Sobel’s most recent book, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos.  This book also contains the play And The Sun Stood Still, which will be presented in a free staged reading by the Boulder Ensemble Theatre Company this Thursday, September 20th at 6:30 at the Dairy Center for the Arts.

Public health risks of BPA

Dr. David Dausey, Director of the Mercyhurst Institute for Public Health
(start time: 5:50). We Coloradoans pride ourselves on our healthy habits — eating right, exercising, and paying attention to what’s in the food we eat. Yet many of the things we use everyday, like water bottles, sunscreens, makeup, and – OK, soda cans — are full of toxic chemicals. Many of them are untested, and may be insidiously making us sick. One of the more controversial compounds is BPA, which is used to make some hard plastic bottles and other food packaging. Today we have with us public health expert Dr. David Dausey to talk about BPA –bisphenol A — and other environmental toxins. He directs the Mercyhurst Institute for Public Health in Pennsylvania.

Planetary Sciences Budget // Curiosity’s RAD

Donald Hassler
Curiosity’s RAD (start time 7:14). To design a successful manned mission to Mars, we’ll have to know a lot about the radiation environment between the Earth and Mars and on the planet’s surface. The Radiation Assessment Detector (RAD) instrument on Curiosity is designed to make those measurements. We talk with Southwest Research Institute’s Dr. Donald Hassler, the RAD instrument Principle Investigator, about RAD’s purpose, how the instrument works, and the joys and scary moments that come with working on Mars.

Planetary science budget (start time: 15:49). Despite the successes of the Mars missions and voyages to our other planetary neighbors, the White House decided that NASA’s planetary science budget should be drawn down. The hit would be substantial, a twenty percent reduction from 2012. 300 million dollars would be removed from a baseline one and a half billion dollars. We ask Dr. Alan Stern, who has served as the chief of the Science Mission Directorate at NASA, about why the planetary science budget should be restored.

Volcanoes & the Atmosphere // Traffic in Beijing

Volcanoes & the Atmosphere (start time 6:17): We’ve known for a long time that volcanic particles and gases can travel around the world, often affecting climate.  The 1815 eruption of the Indonesian volcano Tambora chilled New England and Europe, resulting in what came to be known as “the year without a summer.”  More recently, the 1991 eruption of Pinatubo in the Philippines cooled temperatures throughout the Northern Hemisphere by up to 0.6 degrees Celsius. Those were both sizable eruptions.  Co-host Beth Bartel talks with Bill Randel, division director of the Atmospheric Chemistry Division at the National Center for Atmospheric Research, about what a mid-sized eruption in the horn of Africa can tell us about atmospheric circulation.

Traffic in Beijing

Traffic in Beijing (start time 15:13): A new study shows that China gets a gold medal for dramatically reducing carbon dioxide emissions during the 2008 Olympics in Beijing. Yes, that’s Beijing, one of the most polluted cities in the world. The new study shows that China severely restricted auto traffic in the city, leading to a major reduction in global greenhouse gas emissions. In fact, it could be enough to make a dent in curbing climate change if similar efforts were to be made in cities around the world, and on a sustained basis. Co-host Susan Moran discuss the new paper and its implications with Helen Worden of the National Center of Atmospheric Research.
