A hallmark of science, of course, is that new data may always emerge that challenge accepted conclusions (why, just last week, we discussed such “unknown unknowns”). However, the more robust the conclusion, the more likely that new and unexpected data will serve to reinforce, not discredit it. And we find that here, with the longest known citizen-scientist record to date being found to be entirely consistent with all the other evidence for anthropogenic climate change. Also some nostalgia, and a few examples of the crazy coolness (and potential power for good) of evolutionary thinking.
