Among the casualties is the National Weather Service , which supplies critical data from air balloons and climate models to develop weather forecasts. Many cities and agencies use these data to warn the public when extreme weather, such as a hurricane, is approaching. This crisis has prompted some climate scientists and meteorologists to organize a marathon five-day event, starting May 28, to educate the public about how vital their work is to society, and to mobilize people to take action. Host Susan Moran interviews two climate scientists who are on the organizing team of 100 Hours to Save America’s Forecasts .

Photo credit: Sujata Gupta Birds: Risk and Resilience (start time: 5:55) What speaks of Spring more than the songs of American robins, yellow warblers, spotted towhees and other birds in the early morning? As we relish in these avians choruses, it’s also an important time to examine why bird populations in North America have, by and large, been plummeting in recent decades, due to multiple stressors, including climate change and habitat destruction. At the same time, some conservation efforts (including bipartisan legislation) on the federal , state and local levels, are bearing some fruit. And everyone can help give these winged creatures a hand, starting with their own gardens, and by getting involved in citizen science projects, such a bird-banding and bird-counting. In this week’s show, host Susan Moran interviews Arvind Panjabi , a senior research scientist at Bird Conservancy of the Rockies , a nonprofit organization devoted to the conservation of birds and their habitats.

Sweet in Tooth and Claw (start time: 0:59) Since the 1800s, science has been obsessed with the notion, stemming from Charles Darwin’s theory of evolution through natural selection, that only the “fittest” can survive and pass on their strong genes. As in, it’s a ruthless, violent world. And today, we humans find ourselves mired in a hyper-polarized society fixated on competition, disruption, and “If you win, I lose” thinking. A good time to take a look at a different way of living together–how a “kinder, gentler” approach also helps species evolve. In this week’s show, Susan Moran interviews journalist/author Kristin Ohlson , whose most recent book, Sweet in Tooth and Claw: Stories of Generosity and Cooperation in the Natural World , was recently released in paperback by Patagonia Works.

oil and gas rig Image courtesy of USGS NEPA rollbacks, environmental impacts (start time: 6:25) Amidst a flurry of moves by the Trump administration to roll back environmental regulations, last month a White House agency proposed a rule to rescind a landmark law meant to protect wildlife, their habitat, and human communities from unchecked development, and to ensure that the public has a say in projects ranging from oil and gas drilling to wind and solar farms. The rule, if it goes into effect, would mean that the White House Council on Environmental Quality would no longer enforce how the National Environmental Policy Act (NEPA) is carried out. As a result, many infrastructure projects would not be subject to environmental review. A public comment period regarding this proposed rule ends on Friday, March 27.

Landfill photo credit: iStock Tackling CH4 emissions from landfills (start time: 5:59) Methane is an extremely potent greenhouse gas, and its emissions have been rising recently in the U.S. The largest source of methane emissions is oil and gas production, followed by livestock farming. The third largest source of methane emissions is landfills. Food scraps, yard debris, paper and cardboard products and other carbon-based detritus that pile up in landfills release methane and other chemicals as they decompose in the soil. As part of the state’s goal of slashing greenhouse gas emissions, the Colorado Department of Public Health and Environment is developing new, and stricter, rules that will require landfill operators to do more to monitor and capture methane emissions.

Concrete mixer truck Tackling Cement’s Huge Carbon Footprint (start time: 0:58) It’s hard to imagine modern society without a key material that so many structures depend on– cement. Think of our houses, apartment and office buildings, hospitals, parking lots, bridges, and, increasingly, massive data centers of big-tech companies. But that societal glue of sorts comes with a big climate price tag. C ement production accounts for more than 7 percent of global greenhouse gas emissions . That’s way less than the amount from coal and oil & gas production, but roughly double the emissions from aviation. So, finding ways to reduce the carbon footprint of cement could go a long way toward curbing the momentum of climate change and its impacts. But some players in the industry, as well as in state and federal governments, are making strides to clean up the cement industry’s act . In this week’s How On Earth, host Susan Moran interviews Anish Tilak , a civil and environmental engineer who is a a manager of the Carbon-Free Buildings program at RMI (founded as Rocky Mountain Institute); and Cory Waltrip , a senior manager at the startup Sublime Systems , in Somerville, Mass.

Indeed, plastics, mostly made from fossil fuels, are wreaking havoc on our environment and potentially our bodies. Although it’s still unclear precisely how much our bodies are accumulating tiny plastic particles, and to what effect, scientists are warning that nanoplastics could be altering our brains, our reproductive system, and our metabolism. Recently, representatives from many nations, including the United States, met to reach a first-of-its-kind United Nations global treaty to tackle plastic pollution. They failed.

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 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.

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 h ow 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 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.

In this week’s show Beth spoke with Marc Bekoff, well known and loved for his decades of research into animal behavior, emotion and cognition, about the new edition of his classic book, The Emotional Lives of Animals. Marc Bekoff is professor emeritus of Ecology and Evolutionary Biology at the University of Colorado, Boulder. For decades he has studied animal behavior, cognitive ethology (the study of animal minds), behavioral ecology, and written extensively on human-animal interactions and animal protection. He centers his work and writing around compassionate conservation, namely the principle of, “First do no harm” and the life of every individual matters because they are alive and have intrinsic value, not because of what they can do for us. We talked about the new edition of his classic book, The Emotional Lives of Animals , and many related topics. On his website you can find links to his many books, articles, and remarkable listing of honors and awards. If you frequent the dog parks in Boulder, you may see him watching and talking to the dogs.

Animal Communication Science (start time: 2:57) Whether you own a dog or horse, or have listened to dolphins, wolves, chimpanzees or other wild animals, you’ve probably wondered what they’re saying when they communicate vocally – and why do they communicate the way they do? Our guest, zoologist Arik Kershenbaum , explores recent scientific discoveries in animal vocal communication in his new book Why Animals Talk: The New Science of Animal Communication (Penguin Press). His exploration of wolves howling, dolphins whistling, gibbons warbling, and far more, poses more questions than answers about the natural world, including our place in it. In this week’s science show (listen here or download the podcast) host Susan Moran interviews Dr. Kershenbaum, a lecturer and fellow at Girton College, University of Cambridge, where he is a member of the Bioacoustics Research Group . Previously he wrote the book The Zoologist’s Guide to the Galaxy . Hosts : Susan Moran, Joel Parker Show Producer/Executive Producer : Susan Moran Engineer : Joel Parker Listen to the show here:…
