This is a subject I don't address enough on this blog. The issue, however, is among the most important - if not the most important - facing humankind. The warming-trend facts are in and have been for a while. Moreover, the overwhelming majority of climate scientists agree humans are contributing to the trend. To what degree remains unclear, but if it's greater than zero, then the need for a course of action is obvious.
Below is an interview on Democracy Now, which simultaneously highlights a good article (link also below) as well as the fact that the piece appears in the business press. Hopefully, Paul Barrett's article indicates a shift in broader acceptance of the realities facing the planet.
