During one of my recent climate change presentations a member of the audience broke into the middle with an obvious challenge about the Great Barrier Reef dying because of ocean acidification. Rather than go off track I expressed my doubts saying that’s not what I recalled and tabled it until the end. I had some understanding about the GBR, but had to do more research. The claim is wrong on two points.
Above a pH of 7.0 a solution is alkaline and becomes more or less alkaline.
Below a pH of 7.0 a solution is acidic and becomes more or less acidic.
The ocean's pH is about 8.0. That's alkaline. Variations are more or less alkaline, not more or less acidic. The obvious reason for incorrectly using the term "ocean acidification" is a propaganda gambit to scare the gullible and uninformed who associate acid with bad, like alien blood and spit.
Highly alkaline compounds such as caustic soda can be just as dangerous as acidic compounds, e.g. concentrated bleach, sodium hypochlorite, pH 9 to 13. On the other hand: rain has a pH of 4.5, lemon juice has a pH of 2.0, tomatoes a pH of 4.5, and vinegar a pH of 2.2. If they get on your hands the flesh doesn't melt and they don't burn a hole in the kitchen counter.
Improperly using the term "acidification" to scare the public over bogus CAGW is a disgrace to science. Spit out the Kool-Aid and grow a backbone.
Bleaching is not dying. There have been numerous bleaching incidents in the past. Bleaching is caused by, among other causes, warm water temperatures especially those caused by El Ninos and NOT pH. The GBR has always mostly recovered. Long term damage or death has been relatively minor. The polyps and other life that inhabit the coral structure die when the water gets too hot or too cold or too fresh and when the conditions revert they recolonize. That’s the way it has been going for millions of years.
Also during the post presentation the same person stated another BS MSM sound bite and another member of the audience pronounced it BS whereupon they got their undies in a knot and stomped out of the room like a six year old possibly to go whine at their mommy.
If you thin skinned uppity millennial snow flakes don’t want your BS challenged quit believing the MSM and green web site sound bites & do your own homework and thinking!!! Yes, saving the world makes one all warm and fuzzy. Too bad it’s not real.
Per GBRMPA over 75% of the GBR is just fine. 22% is badly damaged, 85% of that is in the northern sector and El Nino was at fault.
