I mean given what we know about the Sahara and its wet and dry periods, it doesn’t seem at all illogical that ocean currents should start and stop to match. I think it’s important to understand that the earth is deeply dynamic and constantly changing, and has incredible variation in often cyclical patterns over hundreds, thousands and tens of thousands of years. While we know human caused elements are accelerating trends, it’s important to separate the human accelerant from the fact that the Earth herself goes through regular and quite massive changes — that climate change can affect — but that are normal, quite natural and quite civilization and food growing pattern interrupting sized. We have been in a period of unusual climate stability… Edit: I’m getting heavily downvoted so I feel the need to clarify, as this comment is not incorrect or even controversial in climate circles. We have experienced rapid changes inside of single human lifetimes many times, and It’s important to be able to talk about science openly without labeling everyone who doesn’t parrot exactly the narrative you expect them to conform to just because it kinda sorta looks like a climate denier even though it isn’t. Very much not what I would expect of the HN crowd. Here’s a write up: > Most likely, freshwater delivered from the ice sheet to the North Atlantic periodically disrupted the overturning of the ocean, causing the transport of tropical heat to the north to reduce and then suddenly increase again. While this mechanism is unlikely to occur today’s world, it does show us that, at least regionally, the climate is capable of extraordinary changes within a human lifetime – rapid switches we certainly want to avoid experiencing. https://www.bas.ac.uk/data/our-data/publication/ice-cores-and-climate-change/ https://www.bas.ac.uk/data/our-data/publication/ice-cores-an... Further: > A new study suggests climate conditions in the Sahara Desert have changed from wet to dry about every 20,000 years. The study was carried out by scientists at America's Massachusetts Institute of Technology, or MIT. Findings were published in the journal Science Advances. https://learningenglish.voanews.com/a/study-africa-s-sahara-changed-from-wet-to-dry-every-20-000-years/4727881.html#:~:text=A%20new%20study%20suggests%20climate,in%20the%20journal%20Science%20Advances https://learningenglish.voanews.com/a/study-africa-s-sahara-.... There is precious little discussion of the research on natural climate change and the patterns that man made climate change is enhancing, and it’s very, very important to learn about the natural cycles and how man made climate change changes them. If that’s worth downvoting simply because it doesn’t align with the Only Allowed NarrativeTM for anything climate related then HN is no longer the discussion platform for reasonably intelligent people it once was and that would be very sad indeed.
