In last month’s election, Boulder voters gave the go-ahead for the city to move forward on municipalizing the electrical utility.  The chief motivation for that decision was to put more renewable energy on the grid.  There are a large number of policy options to incentivize renewable energy – so many that it’s hard to keep them all straight.  John Farrell, a Senior Researcher at the Institute for Local Self-Reliance, joined us by phone to explain the situation.  (interview begins at 6:25)

Mountainous areas like the Rockies are hotspots for plant and animal biodiversity but as the climate warms many of these species – including Colorado’s iconic pica — are under threat.  Much research has focused on the effects of temperature change, but less has focused on the interactions of temperature and precipitation in a changing climate.  University of Colorado biologist Christy McCain is closely examining those inter-relationships.  She’s been studying patterns of diversity for plants and critters on mountains around the world. She co-authored a paper that was recently published in the journal Ecology Letters about how precipitation changes appear to be far more risky than temperature change. And it doesn’t bode well for many species. (interview begins at 14:58).
