I was in Banff for a week on a summer school in climate engineering with a crew of graduate students, faculty and other experts in social, political and scientific issues around geoengineering (or climate engineering). We gathered to ask (answering is more difficult), with great humility and no small amount of trepidation, difficult questions and challenges around if, when and how this such technologies should be used, and to ruminate over the possible need for them as mitigation of climate gases does not proceed nearly fast enough to steer us away from a host of dangerous climatic consequences.

Even the considerable weight of these issues, however, could not dampen the delight of staying for a week in Banff National Park. Fortunately I did have some time for sightseeing. You could scarcely imagine a more beautiful setting for a town, along the Bow River, among tall and imposing peaks. Here’s a view of downtown Banff with Cascade Mountain in the background.
