It is difficult to know what to make of Pope Francis’ recent encyclical, Laudato Si’, writes Joe Kennedy in Innovation Files. Although formally devoted to global warming, the science and policy of climate change is mentioned only in passing. None of the encyclical’s 172 footnotes cite scientific or economic works. The facts associated with neither the immediate topic nor with broader ecological concerns are never examined in any depth. Instead, readers are treated to a lengthy discussion of church philosophy on the relationship between man, God, and nature, illustrated by numerous quotations from past church leaders. Although critics have faulted the encyclical for many things, its language is too general and enough caveats are thrown in that such attacks seem overdone. The real problem is that, other than love each other and live more simply, it is difficult to know what Pope Francis would have us do differently.
