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.
