This is a bonus(!), crossover(!) episode, produced by Miriam Quick and Duncan Geere's wonderful Loud Numbers podcast, which turns data into sound. Remember the Canadian wildfire data featured a couple of episodes ago? Duncan and Miriam have woven it into a sonic tapestry, threaded with descriptions of the 2023 fire season by Fern Yip, who spent much of it fighting to save her home and school from burning. You can also listen to the episode in Loud Numbers' own podcast feed, and read Miriam and Duncan's show notes for more details.
