Brian Ettling wears many hats: the Smokey Bear Stratton of a National Park Ranger, some cool driving/cycling caps, and the Green fedora of a citizen spokesperson for the (international) Climate Reality Project. Brian talks to Earthworms today by phone, en route to his summer seasonal ranger gig at Crater Lake National Park - where one of his interpretive duties is to talk to visitors from around the globe about the issue of Climate Change.

What are some conversational keys to engage one's fellow humans with this topic, especially when the guy you're talking to is convinced it's all a hyped-up myth? And how can HOPE always figure in to a topic that's so huge it freezes up people's capacity to care and respond? Brian Ettling has worked this out - as you, dear Earthworms listener, will hear, and can see in some of his personal postings. 

This conversation also says HAPPY CENTENNIAL to our U.S. National Park Service, in the first of this year's Earthworms spotlights on this jewel of nature and culture.

Music: Cadillac Desert - performed live at KDHX-St. Louis by William Tyler.
