There is yet another illustration of climate change with news that the seaweed forests of Tokyo Bay have been largely replaced by corals, from the south, in the warming waters (https://www.theguardian.com/world/2020/aug/19/tokyo-bays-seaweed-forests-and-prized-abalone-that-live-in-them-disappear). We may think that this is a 'good thing' but the fisher folk of Kyonan have lost the once thriving abalone and sardine industries that were supported by the seaweeds. I also suspect that the algae were rather better at extracting carbon dioxide (a 'greenhouse gas') from the air than their coral replacements.
