The state of South Australia is sparsely populated by global standards. There is nothing between its south facing beaches and the Antarctica, so, its waters are normally clean and cool. The following, however, is an extract of an article on recent observations by a fisherman. I hasten to say the reason for this problem that he is describing is still under investigation, so I do not pin it on global warming. But the story might help us to consider, when we think of global warming by one or two degrees, that it is not only about human comfort in that ambient temperature. It is about the ecosystems in which we reside and on which we rely, as well. Here is the article: "Marine life sick in warm water [seventh generation fisherman] Mr Dickenson's concerns come amid testing near Victor Harbor, about 200 kilometres to the north-west, where surfers reported falling ill following swimming in foamy water along with dead octopuses and other fish washing up on the shore. The water Mr Dickenson fishes in has been significantly warmer than usual according to his boat's readings, observed at up to 23 degrees Celsius. Mr Dickenson said fish and octopuses in the ocean appeared to be unwell. "We've picked up a lot of octopus off the bottom that are very docile. It's like they're starved of oxygen," he said. Boatswain Point resident Donna Isaacson walks along Long Beach most days and has noticed an increase in sea creatures such as seals washing up on the beach." We do not like long reads and so this was a short extract of a longer article from 23 March 2025. But I wonder if there are similar stories around the world? We are filtered so much to our local news, these days, that probably we wouldn't know.
