During the second part of the show, the conversation was all about beavers!  Marshall Wolf, a phd candidate at Utah State University, joined Chris and Nell to cover the rich history of beavers in Summit County, and how they have impacted our local geology and play a key role in native ecosystems.  He also shared information about his project in partnership with Swaner Preserve, using beaver-inspired restoration techniques to restore a healthier ecosystem and carefully monitor the changes taking place.  

The 120th annual Audubon Christmas Bird Count is scheduled to happen this weekend, and the local chapter will be hosting a Christmas Bird Count, which will kick off at Swaner Preserve and EcoCenter before spreading out to local reservoirs and birding hotspots.  Novices and experts are welcome to join in this nationwide citizen science effort to collect data on local bird populations.  Local birder Nate Brown joined Chris and Nell to share the details. Registration at through the calendar.  


 This Green Earth's Chris Cherniak speaks with journalist and author Jon Waterman about his recent Op Ed in the New York Times titled:  Our National Parks are in Trouble.  Mr. Waterman is a former park ranger, and in the piece he describes how over-crowding, invasive species, climate change and budget cuts are threatening the health and welfare of our national parks.    

 This Green Earth  interview with attorney Rob Bilott who talks with Chris and Nell about his book "Exposure - Poisoned Water, Teflon and the Dupont Corporation".  The book is now a major motion picture titled:  "Dark Waters".  

Winter time is setting in, and as snow levels rise, air quality sometimes falls.  On today's This Green Earth, cohosts Chris Cherniak and Nell Larson speak with Adrian Dybwad who founded a company called "Purple Air", who manufactures a device that can measure and report air quality conditions anywhere, and in real time.  

In this interview on This Green Earth Chris speaks with Walt Meier, a Senior Research Scientist with the National Snow and Ice Data Center about Arctic sea ice and why this year may end up being the lowest areal extent of ice ever measured and recorded.    

During the second segment, Chris and Nell spoke with Jon Devine, Director of Federal Water Policy for Natural Resources Defense Council to learn about the Trump administration's repeal of the Clean Water Rule, what has motivated this move, and what it means for water quality and drinking water in the United States.

During the first segment of the show, Nell and Chris spoke with journalist and author Eugene Linden who recently published an Op Ed in the New York Times titled How Scientists Got Climate Change So Wrong.  Linden made the case that what was once thought of as far-off worst-case scenarios have now turned out to be - in many cases - reality, leaving cities and countries with little time to prepare for the accelerating changes in weather and ocean levels.  Linden shows that the pressure for scientific consensus and immense political pressure have contributed to the watering-down of climate co

During the second half of the show, Nell and Chris turn their attention to the Citizens Climate Lobby, speaking with Lauren Barros, who is currently representing the Wasatch Back Chapter of the organization while meeting with lawmakers in Washington DC.  They are educating western representatives and senators on  HR763, the Energy Innovation and Carbon Dividend Act of 2019, a national, revenue-neutral carbon fee that would also pay out monthly dividend payments to all Americans.

Last week on This Green Earth, a scientist from the research group Climate Central talked about a recent study showing that rising seas will impact more coastal land than initially thought.  This week, cohosts Chris Cherniak and Nell Larson turn their attention to the resiliency which those vulnerable communities will have to develop in order to address not just rising seas but, in our case, a warmer, dryer mountain west.  They speak with Alice Hill, the author of the book Building a Resilient Tomorrow - How to Prepare for the Coming Climate Disruption.   

Sea level rise is a reality being modeled by scientists and faced head on in many cities and communities now struggling to defend themselves against these changes - and adapt to them.  New research published last week in the journal Nature Communications shows that rising seas could affect three times as many people by 2050 than previously thought, threatening to erase some of the world's great coastal cities.  Benjamin Strauss, the Chief Executive for the research group Climate Central, joined Chris and Nell in the first part of the show to discuss his research.

Keeping with the dark sky theme, Utah Master Naturalist Program Director Mark Larese-Casanova joined Chris and Nell to announce the launch of the new Master Astronomer Program, Dark Sky Observations, which covers everything from dark sky ecology to constellation identification.  It's designed for novices, and includes a short online course as well as a three day field course coming soon!

Over recent decades, light pollution has exploded, impacting wildlife, people, and our view of the night sky.  Over the past few years, however, Utah has become an international leader in dark sky protection, led by the Utah State Parks.  From International Dark Sky Park designations to new programs, there's lots happening and opportunity to get involved.  Justina Parsons-Bernstein, Education Specialist with State Parks, joined Chris and Nell to fill them in.

Carl Moore of PANDOS, a Utah-based native and environmental rights organization, joined Chris and Nell to talk about their work and the film Common Ground: The Story of Bears Ears. The film aims to humanize this very polarizing issue through interviews with people of all perspectives, and will be showing locally at the Santy Auditorium October 22nd at 6pm.  

In 2019, global sea ice reached the second lowest extent of the 41 years on record.  Walt Meier with the National Snow and Ice Data Center joined Chris and Nell to talk about this as well as the other work of the NSIDC and the outlook for a north pole without ice within this generation!
