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.
