COP25 Postmortem (start time: 3:35) Earlier this month many nation’s leaders, as well as scientists, environmental activists, companies and others gathered in Madrid for a two-week United Nations climate summit. The conference, called COP25, is rooted in the 2015 Paris Agreement, which is a blend of pledges from about 200 nations to dramatically slash their planet-warming emissions. Next year’s meeting is when signatory nations will update their actual commitments. So, what happened at the recent climate summit, and what’s next? How On Earth host Susan Moran today interviews two scientists who attended COP25. Tashiana Osborne is a PhD candidate in atmospheric and oceanic science at the Scripps Institution of Oceanography, at UC San Diego. And Sarah Whipple is a PhD candidate in ecology at Colorado State University.

COP25 & Climate Change (start time: 1:07): Next month (Dec. 2-13), the United Nations global climate change summit, known as COP25, will take place in Madrid. Many scientists, environmental nonprofits, students, activists will also attend side events related to the UN sustainable development goals (SDG). The goal of COP over the years has been to reduce emissions of planet-warming gases. The talks stem from the landmark 2015 Paris Agreement, which essentially is a mix of pledges from about 200 nations to dramatically cut their greenhouse emissions. The countries are not legally bound to meet their targets, but they are supposed to report their progress to the UN. Under the Obama administration, the U.S. vowed to reduce emissions about 28 percent below 2005 levels, by 2025. But earlier this month, the Trump administration announced that it will begin a year-long process to withdraw the U.S. from the international accord. The stakes are extremely high.

How On Earth’s Susan Moran and guest-host Tom Yulsman discuss COP25 and what’s at stake with Gillian Bowser, an ecologist and research scientist at Colorado State University who has studied international climate and biodiversity conventions and has attended several COP summits; and Tashiana Osborne, a PhD candidate at the Scripps Institution of Oceanography at the University of California, San Diego, who is studying the effects of atmospheric rivers, and who will attend COP25. Tom Yulsman, a CU Boulder journalism professor and blogger, offers his expertise as a climate-focused science journalist.

Tackling Ozone Pollution

Tackling ozone pollution in Colorado (starts at 3:55): Cooler fall weather might soon bring back the bluebird skies we all love. But last year ozone levels in the Denver metropolitan area were high enough to prompt state health officials to issue ozone action alerts an average of once a week. (This summer has fared somewhat better.) During these ozone alerts, health officials recommend that children, the elderly and people with compromised lungs do not exercise outdoors. Hosts Daniel Glick and Susan Moran interview John Putnam, the environmental programs director for Colorado’s Department of Public Health and Environment, about the science, the sources (the largest being oil and gas operations), the health impacts, and policy approaches to ozone pollution. Governor Jared Polis named Putnam to tackle, among other things, a longstanding problem with the state’s air quality: parts of the state have been out of compliance with federal Clean Air Act standards for more than a decade. Last year, the Environmental Protection Agency upped the ante. It declared that parts of Colorado are in “serious” non-compliance of federal air quality standards for ozone, which we all know as “smog.”
For more info on health impacts, read Susan’s article. For info on in intricacies of the state’s oil and gas rules, read this article by Daniel. And the CDPHE features ongoing info on ozone here.

Toxic Air’s Health Risks

Air Pollution, Possible Solutions
(start time: 2:36) It is ubiquitous and essential to our life. It it is also the cause of some 7 million premature deaths around the world every year, ranking just behind diet, cancer and tobacco as a health risk. That’s the air we breath. Beijing, New Delhi, and London are among the smoggiest, but the Denver metro area isn’t faring so well either. Yet many countries and cities have taken positive steps that have dramatically reduced emissions, from vehicles, smokestacks, crop and animal production, and other sources. Our two guests today have been researching air pollution—its sources, impacts and solutions–and they share their insights and data with How On Earth’s Susan Moran and guest host, journalist Jason Plautz. Beth Gardiner, an environmental journalist based in London, authored the recently published book Choked: Life and Breath in the Age of Air Pollution. And Dr. Frank Flocke is an atmospheric scientist at the National Center for Atmospheric Research, and an author of a major study of air pollution sources on the Colorado Front Range.

Plastic Pollution & Solutions

Tackling Plastic Pollution (starts at 3:09): It is, sadly, common for beachcombers around the world to see, along with clam shells and sand dollars, plastic bottles, bottle caps, cigaret filters and fish nets washed up on shore. According to estimates by World Economic Forum, our oceans will be populated by more pounds of plastic waste than fish by 2050. About a third of all plastic that is produced does not get properly collected; instead, much of it ends up floating in the ocean, or clogging the guts of innocent albatross, other birds and sea mammals. It could take 450 years, or forever, for plastic to completely biodegrade. Plastic waste just breaks down (photo-degrades) into tiny bits, causing harm to wildlife and, potentially, humans. How On Earth host Susan Moran and contributing host Jeff Burnside interview two guests who are working in different ways to assess the extent of the problem and its impacts, to educate people about it, and to effect positive change. Dr. Jenna Jambeck, an associate engineering professor at the University of Georgia, lead-authored a seminal paper in 2015 that estimated how much plastic waste is in the ocean. She will soon co-lead an all-female National Geographic expedition to study plastic pollution in India and Bangladesh. Laura Parker is a staff writer at National Geographic magazine covering climate change and ocean environments. She won the Scripps Howard award for environmental reporting her June 2018 National Geographic cover article titled “Planet or Plastics?”

Pesticides and Health Impacts

A Consumer’s Guide to Pesticides in Produce (starts 7:55) You may be wondering if you washed the strawberries, blueberries or kale that you had for breakfast this morning enough to rid them of residue of potentially harmful pesticides. That is, if they were conventionally, not organically, grown. According to the U.S. Department of Agriculture, more than 200 different pesticides remain in some form on popular fruits and vegetables that Americans eat every day. And before testing all the produce, the USDA thoroughly washes and peels them. Such tests show that simply washing produce does not remove all pesticides. In a recently released report, as part of its “Shopper’s Guide to Pesticides in Produce,” The Environmental Working Group ranked the pesticide contamination of 47 popular fruits and vegetables. Its analysis, which was based on results of nearly 50,000 samples of produce that the USDA tested, found that 70 percent of produce contains pesticide residues. But don’t despair: There is also good news in the report. Sydney Evans, a science analyst at EWG, and Liza Gross, an independent investigative reporter, speak with host Susan Moran about the EWG report and the broader societal and environmental implications of pesticides. See Liza Gross’ articles on pesticides and other issues.

The Goodness Paradox – Full Interview

The Goodness Paradox (Starts 5:22): On this week’s show we play the full interview with Richard Wrangham, a primatologist at Harvard University, about his new book, The Goodness Paradox: The Strange Relationship Between Virtue and Violence in Human Evolution. Wrangham discusses with How On Earth hosts Susan Moran and Chip Grandits how, and why, homo sapiens evolved to be both peaceful and violent (less reactively aggressive and more proactively aggressive, like our bonobo ancestors), and what it bodes for the future of human civilization. On the pledge-drive show last week we played short snippets of the interview. And thanks to our listeners who pledged, some of whom received a copy of The Goodness Paradox. And thanks again to Pantheon Books for donating them.

The Science of Exercise Recovery

Athlete’s Guide to Recovery (starts at 5:39): Colorado is riddled with athletes, many of them incessantly chasing the latest recovery products and services that will enhance their performance — from Gatorade and other ubiquitous sports-recovery drinks, to supplements, to compression boots, to cryochambers, to good old-fashioned massages. How solid is the solid the science behind the multi-million marketing campaigns? Christie Ashwanden, a former pro cyclist, runner and skier, is also the lead science writer at FiveThirtyEight, and her new book explores the scientific research, the snake oil, and common sense practices, in the world of exercise recovery. Good to Go: What the Athlete in All of Us Can Learn from the Strange Science of Recovery (Norton), was just published today. Christie will also speak about her book tonight at the Boulder Book Store, and tomorrow in Fort Collins at Old Firehouse Books.

Composting & Carbon Farming

Why Compost? (start time: 7:01) Many of us may feel a little less guilty letting fruits and vegetables go bad, because we figure that this waste, thanks to curbside compost pickup, will be turned into nutritious food for crops, lawns or grasslands down the road. And landfills will spew less methane, a greenhouse gas far more potent than carbon dioxide. The story of food waste and reuse is a complicated one. Our two guests are working on getting composting right — and ultimately on how to make our food-production and consumption systems more sustainable, starting here on the Front Range. Dan Matsch directs the compost department for Eco-Cycle, the nonprofit recycler that works with cities along the Front Range. He also directs Eco-Cycle’s Center for Hard-to-Recycle Materials (CHaRM). Mark Easter is an ecologist at Colorado State University’s Natural Resource Ecology Laboratory. Matsch and Easter discuss with host Susan Moran the journey of a rotten zucchini, how composting is tied to the emerging practice of carbon farming, and how we all do our part.

Calendar advisory: Join KGNU and Eco-Cycle on Thursday, January 31, at the Longmont Museum (6:30 to 8:00 P.M) for a special community conversation on plastic waste–challenges and solutions. The event will include representatives from Eco-Cycle, the Inland Ocean Coalition, and local business and sustainability leaders. For more info, go to this website.
