Where is Science Going in the Next 4 Years?

WASHINGTON, DC – APRIL 05: U.S. President Donald Trump and Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, hold a press briefing with members of the White House Coronavirus Task Force on April 5, 2020 in Washington, DC.

Today on How on Earth, Beth speaks with Dr Jon Samet, former dean of the Colorado School of Public Health and Professor of Epidemiology and Occupational and Environmental Health. Dr. Samet has served on and chaired numerous committees of the National Research Council and Institute of Medicine, also chairing the Clean Air Scientific Advisory Committee of the U.S. EPA and the FDA’s Tobacco Products Scientific Advisory Committee. He has an insider view on some of the implications of the newly elected administration for science.

Today’s show features NASA’s Europa Clipper mission, which launched on October 14th, 2024 on a Falcon Heavy rocket, setting the spacecraft on its 10-year journey to explore Jupiter’s moon Europa.  Europa Clipper carries nine instruments to study this ocean world covered by an ice shell to determine if there are places in the watery depths below the surface that could support life.  The mission’s goals are to study ice shell, the sub-surface ocean, and the moon’s composition and geology.  Our guest is Dr. Bonnie Buratti, a Senior Research Scientist at the Jet Propulsion Laboratory, and Deputy Project Scientist for the Europa Clipper mission.

COP16 Biodiversity Conference

COP16: Hope & Hurdles (start time: 1:20)  On this week’s show, host Susan Moran interviews two conservation biologists at Colorado State University — Chris Funk and Liba Pejchar. They both recently attended the United Nations Biodiversity Conference, or COP16, which is still underway in Cali, Colombia, and they share their experiences, perspectives, and optimism from the global gathering.  Nearly 200 nations are attending the summit to negotiate targets aimed at slowing the alarming decline in plant and animal species and critical habitats around the world. The outcomes of the talks could determine the roadmap for the future of the planet (despite the fact that the United States has not been a signatory to the global biodiversity treaty). The stakes are high: Biodiversity is shrinking globally faster than at any time in history,  with around 1 million plant and animal species currently threatened with extinction, according to an intergovernmental panel of scientists. Two years ago, the biodiversity conference, which convenes every two years, met in Montreal and hashed out a landmark agreement.  Among the 23 measures in the accord is a commitment to place 30 percent of the planet, and 30 percent of degraded ecosystems, under protection by 2030. Some progress has been made, yet so far no nations have met their targets, and COP has no enforcement mechanism.

Wildfire Mushrooms for Wildfire Mitigation

WIldfire Mushroom c Coldfire Project

Wild, local mushrooms can break down deadwood into healthy soil, and they can do this surprisingly fast.  Used correctly, fungi are an emerging way to reduce the forest tinder that makes mega-wildfires more likely.   But there’s a wrong way and a right way to use mushrooms for mitigation  Our experts today will talk about the ways that are safe for the environment, and the results.

Our experts today are Jeff Ravage of the Coldfire Project and Zach Hedstrom of Boulder Mushroom .  They describe efforts underway to use mushrooms to break down deadwood into soil — to reduce forest tinder and also for sequestering carbon in soil.

Emotions, Beliefs, Politics

Image credit: Brown University

Beliefs, Perceptions, Decision-making (start time: 4:37)  For many people if feels like our society, and our beliefs, have never been as polarized as they are now. Indeed, we are living in a politically polarized society. But it’s not as unique, or as extreme, as many think. In this week’s show we look behind the curtain of our beliefs and behaviors, and we discuss how emotions, far more than reason, determine our decision-making, including how we vote.
How On Earth host Susan Moran interviews Leaf Van Boven, a psychology professor at CU Boulder; and Drew Westen, a professor of psychology and psychiatry at Emory University, in Atlanta, Georgia, who is the author of The Political Brain: The Role of Emotion in Deciding the Fate of the Nation.

The Carbon Footprint of Food

The Blue Plate in a Red-hot World (start time: 7:46) While adding cream to your morning cup of coffee, or digesting the hamburger that you grilled last night, you might not have been asking yourself, What’s the carbon footprint of these ingredients and meals? Understandable. Our guest today, ecologist Mark Easter, however, has pondered this question intensely for many years, when he grocery shops, plans his next meal, and researches. Easter is a so-called greenhouse gas accountant, one who measures the sources and sinks of GHG emissions from agricultural practices.
It’s a vexing and critical calculus. After all, agriculture generates more than 10 percent  of U.S. greenhouse gas emissions. Easter’s debut book,  The Blue Plate: A Food Lover’s Guide to Climate Chaos (Patagonia),  has just been published. It highlights not just the causes of our climate crisis, but also a growing number of farmers, ranchers and orchardists who are practicing low-carbon, soil-enhancing methods on their land, and as a result boosting their crop yields and revenues.
