Tackling Landfill Methane Emissions

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. KGNU host Susan Moran interviews Clay Clarke, director of the Climate Change Program at CDPHE; and Madison Hall, an associate with the Rocky Mountain Institute‘s US Program.

Health Impacts of Wildfire Smoke (start time: 4:22) It’s peak wildfire season. Smoke from forest and grass fires contains particulates that can irritate eyes, throat and lungs — especially in children, the elderly, and people already suffering from asthma, allergies, heart disease. How On Earth host Susan Moran interviews Anthony Gerber, MD/PhD, a pulmonologist and an associate professor of medicine at National Jewish Health and the University of Colorado, Denver, about the medical risks of breathing smokey air and what people can do to minimize the impact. The Colorado Department of Public Health and Environment also offers info and warnings on air quality in Colorado.

Detained Migrant Children Suffer Medically (start time: 17:02) Since April, when the Trump administration’s controversial zero-tolerance policy went into effect to crack down on families crossing the border illegally, more than 2,300 migrant children have been separated from their parents and detained in government detention centers. More recently, about 200 of the children have been reunited with their parents, but bulk of them have not. As a result, many of the children suffer from physical and mental health problems. Colleen Kraft, a pediatrician and president of the American Academy of Pediatrics, talks with host Susan Moran about the medical impacts on migrant children.

Wild Turkeys // Light Pollution

In celebration of Thanksgiving, Beth Bartel interviews Stan Baker of the National Wild Turkey Federation about wild turkeys in Colorado. You may be surprised at the story of the wild turkey in North America and just how different the wild turkey is from the domestic turkeys we’re used to. There’s a reason Benjamin Franklin wanted the turkey, not the bald eagle, to be our national bird.

Can light pollution at night lead to air pollution during the day? Jim Pullen talks with researcher Harald Stark of the Cooperative Institute for Research in the Environmental Sciences (CIRES) to find out. Stark’s work has taken him over Los Angeles to measure the chemistry of the night sky. What he is learning increases our understanding of ground-level ozone, which is a major pollutant of our urban air.
