Climate engineering // Jamie Williams

The Wilderness Society

Jamie Williams (start time  5:40). Today on How On Earth we speak with Jamie Williams about land conservation. It’s safe to say that Williams should take credit for large swaths of land in the West that have been preserved as wilderness. He has served as The Nature Conservancy’s director of landscape conservation for North America as part of a 20-year career at the organization.

During that time he helped forge unlikely partnerships between ranchers, other landowners and environmentalists. And he led major efforts to garner funding in Congress for conservation, including the largest conservation purchase of private land ever – of 500 square miles of forest in northwest Montana.

Williams helped develop the large landscape focus within the Obama administration’s America’s Great Outdoors Initiative, which aims to connect especially young kids to the outdoors.

Today, Williams takes the helm of another major conservation organization, the Wilderness Society.

Climate engineering (start time 18:12). Geoengineering means large scale, intentional manipulation of the climate to counter the effects of global climate change. Advocates have proposed ideas like placing giant shields in space to block the sun’s rays from striking the earth, and seeding the ocean with iron particles to speed up the removal of carbon from the atmosphere. Critics cite a host of social, moral, and technological problems.

Climate engineering may be a solution of last resort, but the time for last resorts may be rapidly approaching as we spew more and more carbon into the air.

We  speak with Dr. Doug Ray about the readiness of climate engineering. Ray is an expert on energy and atmospheric carbon removal science and technology and is an Associate Lab Director at the Pacific Northwest National Laboratory.

Leaky Natural Gas Wells // Measuring Glaciers and Ice Caps

Leaky Natural Gas Wells (start time 6:22).   We speak with Greg Frost, a scientist from the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration (NOAA), about a new study, which is being published by the Journal of Geophysical Research.  The study indicates that natural gas drilling creates higher amounts of methane leakage into the atmosphere than previous estimates had indicated.  Methane is a potent greenhouse gas, and unless this problem of leakage is solved, there is concern that drilling for natural gas might cause higher levels of greenhouse gases in the atmosphere than burning coal.  We also offer an extended version of this interview.

Recent Contributions of Glaciers and Ice Caps to Sea Level Rise (start time 14:25).  Scientists at CU’s Institute of Arctic and Alpine Research now have used eight years worth of satellite data to a clearer picture of how climate change is impacting the cryosphere, or ice-covered parts of the planet. (See animations here.)  Knowing how much ice has been lost during this time can help scientists understand how melting ice might contribute to sea level rise, both now and in the future. But there have been conflicting stories in the press about how the results should be interpreted.  We talk with Tad Pfeffer, one of the study’s coauthors, to discuss what’s really happening to the Earth’s ice.

Leaky Natural Gas Wells [extended version]

Natural Gas Wells Leak More Methane and Benzene than Expected


This is an extended version of the KGNU Science Show, How on Earth.  It features Greg Frost, a scientist with the University of Colorado at Boulder and with NOAA, the National Oceanic and Atmospheric Administration.  He’s on the team led by Gabrielle Petron which has been studying leaks from natural gas production.  In this extended interview, Greg tells us about natural gas wells in Colorado that are leaking twice as much methane and benzene into the atmosphere as official estimates have indicated.  Methane is a potent greenhouse gas. Benzene is a carcinogen.  Let’s listen in now, as Greg Frost tells How on Earth’s Shelley Schlender what their study of leaking methane from gas wells found.



Wildfire Science

October is Wildfire Awareness Month, so on today’s show we look back at the Fourmile Canyon wildfire and hear from local researchers about some of the scientific opportunities that the fire afforded over the last year. Jim Roberts, an atmospheric chemist at the National Oceanic and Atmospheric Administration, tells us about some of the unexpected compounds that have recently been found in the smoke of wildfires. And Deborah Martin, a hydrologist with the U.S. Geological Survey, describes how post-fire runoff from rainstorms affects the forest landscape.

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.
