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.

MDMA for PTSD – Psychiatrist Will Vanderveer

Boulder Psychiatrist Will Vanderveer
Boulder Psychiatrist Will Vanderveer

In the years ahead, doctors across the U.S. might be prescribing a currently illegal drug as therapy for the hard-to-treat condition known as Post-Traumatic Stress Disorder (PTSD).  The new “medicine” would be MDMA, an ingredient in the party drug ecstasy.  The treatment is showing success for many of the study participants (go here for an extended interview with a study participant named Karen).  The lead funder of these FDA approved studies is the Multidisciplinary Association for Psychedelic Studies, also known as MAPS (go here for more about MAPS, plus how to enroll or learn about the studies). 

The Principal Investigator for the Boulder studies is psychotherapist Marcella Ot’Alora (go here for an extended interview with Ot’Alora.)  On Ot’Alora’s team is Boulder psychiatrist Will Vanderveer  How on Earth’s Shelley Schlender shares this in-depth interview with psychiatrist Will Vanderveer.

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.

Urban Air Pollution: A new culprit

It’s the endless stream of tailpipes on the L.A. freeway which  causes that unsightly smog, nagging cough and chronic respitory problems, right?  Perhaps not any more, a new scientific study helps build the case that the major culprit may now be purchases made at the corner drug store or hardware store.  Chip Grandits speaks with Dr. Brian McDonald of NOAA about perhaps changing tactics for the next stage in the human race’s campaign to keep the air clean and healthy in both the indoor and outdoor environments of the urban areas many of us call home.

A couple headlines focus on related aspects of the changing climate in our Alpine environment and what it really means.  Does it seem like spring comes earlier every year, or is that just your imagination?  Well, the science says probably not, especially if you live in the Northern latitudes.  Science journalist Tom Yulsman, who writes about climate change and beyond in his blog ImaGeo for Discover magazine,  offers a headline  the declining snowpack in the Rockies.

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.
