Between Greta Thunberg’s Time ‘Person of the Year’ awards, and almost concurrent end to a do-nothing UN climate talks in Madrid (to borrow from our US Congress lexicon), two things were reinforced, again, these past weeks: the urgency of climate change, and our inability to address it, at least from on-high. Remarkably, however, for an industry that is rooted in evidence, which examines disparities in health and well being across time and space (and especially among groups and sub-groups), and which holds dear an ethical mantra of ‘do no harm,’ Evaluation has done little to either mainstream the role of climate in our own practice, nor to ameliorate the industry’s impact (because, while disparate and far flung, we are an industry).
