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.

Cancer Biology // Oil&Gas Health Impacts

Today’s show offers two feature interviews:
Adaptive Oncogenesis-978-0-674-98596-4-frontcoverNew Theory of How Cancer Evolves Inside Us (start time: 0:58): It is commonly known that cancer afflicts old people more than youth. Conventional wisdom has held we get cancer with age largely because we accumulate lots of genetic mutations over many years, and it’s the mutations that cause cancer. Our guest, Dr. James DeGregori,  deputy director of the University of Colorado Cancer Center, discusses with host Susan Moran his new theory–one that challenges conventional wisdom–about why and how we get cancer. In his new book, called Adaptive Oncogenesis: A New Understanding of How Cancer Evolves Inside Us, DeGregori argues that cancer is as much a disease of evolution as it is of mutation. Mutated cells outcompete healthy ones in the ecosystem of the body’s tissues. Dr. DeGregori is a professor in the Department of Biochemistry and Molecular Genetics at the University of Colorado Anschutz Medical Campus.

Studying Health Impacts of Oil&Gas Wells (start time: 12:54) Many people living all along the Front Range are familiar with the sights and smells of oil rigs operating in fields near their homes and schools.  State regulators argue  that this convergence of people and oil rigs is safe. But many nearby residents and scientists are concerned about the potential health impacts of these drilling operations so close to residential neighborhoods and schools. Our guest, Dr. Lisa McKenzie, is the lead author on a new study that adds some critical evidence to back concerns of residents. It found that for people living within 500 feet of a well, the risk of their getting cancer over the course of their lifetime is eight times higher than the upper acceptable levels established by the federal EPA. Dr. McKenzie is an assistant research professor at the Colorado School of Public Health at the University of Colorado Anshutz Campus. She discusses the study and its implications with hosts Daniel Glick and Susan Moran. (Here is our interview with Dr. McKenzie a year ago about a related study.)

Geoengineering the Climate

Hacking the Planet (start time: 10:24):
It’s tough to wrap one’s mind around just how monumental and consequential the problem of climate change is. So dire that scientist and engineers for years have been exploring ways to “hack” the planet–to manipulate the global climate system enough to significantly reduce planet-warming gases or increase the Earth’s ability to reflect solar radiation. This audacious scheme, called geoengineering, only exists because many scientists think that human behavioral change, industry regulations, international treaties and national legislation, have not done enough — can not do enough – to keep us from careening toward climate catastrophe.
Our guests today have given this huge challenge a lot of thought and some research. 
Dr. Lisa Dilling is an associate professor of Environmental Studies at CU Boulder and a fellow at the Cooperative Institute for Research in Environmental Sciences, or CIRESDr. David Fahey is a physicist at the National Oceanic and Atmospheric Administration, or NOAA.  He directs the Chemical Sciences Division at NOAA’s Earth System Research Lab in Boulder.

Some relevant materials on geoengineering:
2017 study on public perception of climate change;
2015 National Research Council committee evaluation of proposed climate-intervention tchniques.

Enlightenment Now

Book coverYou may be among many who wistfully harken back to the “golden days” of the past. For some people the past does look rosier, or perhaps the present looks grim, but, according to Steven Pinker, a Harvard University cognitive psychologist, that “golden age” of the past is a reflection of faulty memory.

We — most people in the world, anyway — are actually far better off than we were decades and surely centuries ago. That’s based on many metrics of progress, including literacy, safety, gender equality, lower poverty, and many more. Pinker presents in his new book an abundance of data as evidence of such progress. This progress, he argues, is rooted in the ideals of the Enlightenment some 250 years ago.

Pinker’s book is called “Enlightenment Now: The Case for Reason, Science, Humanism, and Progress.” Last week we played a couple of segments of an interview that How On Earth host Susan Moran and KGNU journalist Joel Edelstein conducted with Dr. Pinker. In today’s feature, we play that interview in full.

Enlightenment Now // Pledge Drive Teaser

Book coverToday’s pledge-drive show features parts of our recent interview with Steven Pinker.
Enlightenment Now: If you think the world, including the U.S., is falling apart, that the ideal of progress is as quaint as riding to work on a horse and carriage, you’re hardly alone. But you’re wrong, argues  Harvard University cognitive scientist Steven Pinker in his new book. It’s called Enlightenment Now: A Case for Reason, Science, Humanism, and Progress. As he shows in many copious charts and graphs from studies and national statistics, most people are living longer, healthier, safer, freer, and happier lives. And while our problems are formidable, the solutions, Pinker claims, lie in the Enlightenment ideal of using reason and science. Provocative? Yes. Pollyannaish? No, says Pinker. Today’s show features two sections of a recent interview that How On Earth host Susan Moran and KGNU host Joel Edelstein conducted with Pinker.

We will play the full interview on our March 20th science show. Meanwhile, Pinker will discuss and sign his book at two events on the Front Range on Saturday, March 17. He will be at Tattered Cover Book Store in Denver (2526 Colfax Ave.) at 4:00 p.m. Then he’ll speak at 7:00 p.m. at Unity of Boulder Church (2855 Folsom St.) Check with Boulder Book Store about tickets.

The Starmus Festival

news-placeholder-Starmus-e1517313691450Woodstock.  Lallapalooza. Lilith Fair.  Coachella.  Burning Man.  All famous music and art festivals.  What about…science festivals?  Perhaps a festival with all the “rock stars” of science and space exploration, and while you’re at it, throw in a few music rock stars as well?  Well, that describes the Starmus Festival.  Starmus is the brain child of Dr. Garik Israelian, an astrophysicist who led the team that found the first observational evidence that supernova explosions are responsible for the formation of stellar mass black holes. We talk with Dr. Israelian about the past, present, and future of Starmus.

In today’s show we offer two related features:
Plastic Pollution in the Arctic, Green Chemistry  (start time: 7:48) Try to wrap your brain around this statistic: by mid-century the mass of plastic in the oceans will weigh more than the total mass of fish if we continue with ‘business as usual,’ according to the World Economic Forum. Plastic debris, ranging from plastic water bottles to fish nets to invisible fragments, is choking seabirds and mammals all the way up to the Arctic, and quite possibly harming human health. How On Earth host Susan Moran recently attended the Arctic Frontiers conference in Tromso, Norway, where she interviewed one of the speakers, Jenna Jambeck, an environmental engineer at the University of Georgia. Dr. Jambeck directs the Center for Circular Materials Management, where researchers are designing materials and processes that both reduce waste and, like nature itself, reuse waste.

Grassroots Efforts Curb Plastic Pollution (start time: 20:24) In case you’re wondering what’s land-locked Colorado and your daily life got to do with plastic pollution in the ocean, our guest, Vicki Nichols Goldstein, founder and executive director of the Inland Ocean Coalition, discusses regional and national campaigns to curb plastic waste. The Suck the Straws Out campaign is one of many. You can get involved, starting with attending the Colorado Ocean Coalition‘s Blue Drinks happy hour on Feb. 15 in Boulder.
