Robert Hannon interviewed me in Fairbanks and added the interview to his 2018 Earth Day podcast in between conversations with researcher Kimberly Maher on the effects of climate change on birch sap, and with Fairbanks singer, educator, and environmentalist Susan Grace. My conversation with Robert begins about 14 minutes in the podcast at https://northernsoundings.com/2018/05/01/earth-day/.
