Climate Change & Action: From the Arctic to Colorado (start time: 2:33) Twenty years ago the Academy-winning documentary An Inconvenient Truth was released in theaters nationwide. It sparked millions of people to ask themselves, How can I wake up and do something to help solve, not just contribute to,  the climate crisis?  The film helped form the modern climate movement, following the environmental movement of the 1970s. Two decades later, despite a rise in public awareness of and concern about the impacts of melting sea ice, and intensifying droughts, wildfires and hurricanes, the Trump administration has met the moment by calling global warming a hoax, rolling back environmental regulations, defunding climate science research,  and demanding more oil, gas and coal production.  Meanwhile, many Americans, besieged by soaring costs of gasoline and other commodities, and struggling to pay rent or mortgage, are more immediately concerned  about the economy and other issues than climate change per se. Yet despite shrinking federal support for renewable energy energy, the green electricity revolution is happening in many states and around the world.  In this week’s show, KGNU host Susan Moran interviews Mark Serreze, director of the National Snow and Ice Data Center; and science journalist Tom Yulsman, who until recently was the director of the Center for Environmental Journalism at the University of Colorado Boulder, where he was also a journalism professor.

A Longer Healthier Life

On this week’s How on Earth, Beth speaks with author, psychologist, and aging explorer Alan Carpenter to discuss the paradigm shift on aging he espouses. Following a life changing accident, he turned his life around by diving into the science of healthy aging. In his book, Choose Better, Live Better, he outlines 9 avenues one can address for extending health span i.e. the portion of one’s life spent in good health with the ability to live and function independently.

The Brain on Menopause (start time: 01:24) In this week’s show, we offer the finale of our three-part series on menopause and women’s health. We focus on a most precious organ: the brain. And we discuss how  hormones such as estrogen and cortisol affect brain health; on how experiencing stress during childhood can intensify perimenopause symptoms; and on what women can do to reduce risks as well as to take part in research. How On Earth’s Susan Moran and contributing host Meghan Rabbitt interview Dr. Christina Metcalf, a clinical psychologist and researcher at the CU Anschutz Department of Psychiatry Colorado Center for Women’s Behavioral Health and Wellness.  Journalist Meghan Rabbitt wrote the recently published book The New Rules of Women’s Health: A Guide to Thriving at Every Age.
Information on how you can participate in CU Anschutz research studies:

A Brain Circuit That Switches Acute to Chronic Pain

On this week’s How on Earth, Beth talks with neuroscientist and chronic pain researcher Jayson Ball. He recently completed a study of a novel brain circuit involved in generating chronic pain. Since finishing his graduate studies at CU Boulder, he has moved to Neuralink, a biotech start up focused on implantable brain devices with the goal of someday alleviating chronic pain through this new technology.

Conserving Imperiled Prairie Dogs, Raptors & Their Grasslands

White-tailed Prairie Dogs Credit: Rich Reading

Preserving prairie dog+raptor ecosystem (start time: 5:03)  Spring has just begun, even if winter hardly visited Colorado. On the plains, prairie dog colonies seem to be in full swing.  However, populations of these keystone species have plummeted, as the grasslands they and raptor predators rely on are being fragmented by urban development, as well as oil and gas, and to some degree solar and wind, development. In this week’s show we discuss the imperiled prairie ecosystem and efforts to further conserve them, with Dr. Rich Reading, vice president of science and conservation at the Butterfly Pavilion; and Dana Bove, founder of the nonprofit Front Range Nesting Bald Eagle Studies. Click here for information about and to register for their and colleagues’ upcoming Science and Conservation Symposium (March 31 and April 14) in Denver.

Pollinator Power & Precarity

The Power of Precarity of Pollinators (start time: 8:01) This extremely warm winter in Colorado has delivered early spring blooms, and thus early appearances of some pollinators. In this week’s show we explore the world of pollinators, such as such as butterflies, bees, moths, hummingbirds and certain flies. Pollinators are responsible for roughly one third of the food we eat, and the help strengthen ecosystems. How On Earth host Susan Moran interviews Amy Yarger, senior director of Horticulture at the Butterfly Pavilion in Westminster, Colo., about the critical role these pollinators play; the various threats they face, such as the herbicide glyphosate (Roundup)  and the class of insecticides called neonicotinoids; and how we can help give these important creatures a lift. Yarger leads local pollinator habitat initiatives at the Butterfly Pavilion, a nonprofit research, conservation and education institution focusing on invertebrates and their habitats.
