This reminds me of the time I was on a boat up near the Mendenhall Glacier in Alaska a few years ago. Somebody was pointing out how far the glacier had receded. (It was easy to see because the rock was worn smooth where the glacier had been.) Much clucking about climate change, etc.
Finally somebody asked *when* the glacier had begun to retreat. “In the 18th century” we were told.
A serious, thrawn, and intense woman shot back at me, “Well, the Chinese were burning a *lot* of bamboo, you know.”
