Sea Acidity Has Reached Critical Levels, Threatening Entire Ecosystem 96
The world's oceans are in worse health than realised, scientists have said today, as they warn that a key measurement shows we are "running out of time" to protect marine ecosystems. From a report: Ocean acidification, often called the "evil twin" of the climate crisis, is caused when carbon dioxide is rapidly absorbed by the ocean, where it reacts with water molecules leading to a fall in the pH level of the seawater. It damages coral reefs and other ocean habitats and, in extreme cases, can dissolve the shells of marine creatures.
Until now, ocean acidification had not been deemed to have crossed its "planetary boundary." The planetary boundaries are the natural limits of key global systems -- such as climate, water and wildlife diversity -- beyond which their ability to maintain a healthy planet is in danger of failing. Six of the nine had been crossed already, scientists said last year. However, a new study by the UK's Plymouth Marine Laboratory (PML), the Washington-based National Oceanic and Atmospheric Administration and Oregon State University's Co-operative Institute for Marine Resources Studies found that ocean acidification's "boundary" was also reached about five years ago.

So, glad this place is for geeks and nerds 'cause I'm about to double down. Not only am I a programmer/tech leader (ret.) but I've also been a reefkeeper for even longer - and I started out on trash-80 mod I and PDPs. In laymans terms I have aquariums and I keep corals, fish, inverts, etc.
Now, I neither push the climate panic or climate denier line. I, personally, think it's something to pay attention to - I don't think (hope?) any of us would argue that chemistry actually exists. However, I do think the climate scientists made a HUGE strategic error yelling that the sky is falling from every rooftop they have access to and now Mr & Mrs J. Doe are bored and numb.
I've said for the past 20 years or so that modeling the climate on the level and timeframes they've been claiming is absolutely impossible from a resource and compute standpoint - see all the revised predictions. For the same time, though, I've been saying I *AM* concerned about the interaction of CO2 with the planets oceans - and that's something I do know something about.
Ocean chemistry is pretty well known, fascinating, and pretty accessible, frankly (after all, I get it). I have seen, first hand, in my own home(s), on multiple occasions the effect that a surplus of CO2 on ocean life. Most modern houses are far too well sealed to allow for gas exchange with the atmosphere at large. So with people, kids, dogs, cats, etc consuming the oxygen and filling the place up with CO2 you have to be careful caring for reefs in a house. There are many times I've had to bake baking soda (sodium bi-carbonate) into sodium carbonate to deal with some emergency or another (add to water to capture carbon and it precipitates out). Or, and I don't remember what the material is, off the top, but there's a material that you can run air through on the way to a protein skimmer or other piece of equipment that injects air into the water to remove CO2 (think it's the same stuff that CO2 scrubbers use).
Anyway, the effects that I have personally seen are that corals do struggle to build skeletal material, and can, in fact, lose material as can other inverts (think snails, shellfish, etc). The ideal for marine water is a little north of 8 (8.1-8.2 if I remember correctly - I'm not running a reef right now). And, of course, if the PH is low enough, long enough, mortality goes up across the board.
Anyway, not screaming that the sky is falling, but this is a VERY easy piece of science to check up on yourself - can even run a cheap experiment at home (my daughter did for an elementary science fair project). My only point is that it IS something to pay attention to, definitely. And it's relatively easy to understand, and even see it yourself in action.
