I do understand, but I don't agree. On a planatary scale, the percentage of the impact is what is important.
One drop of pee in the ocean vs 2 drops of pee in the ocean. A 100% increase that is meaningless.
We inverse the problem
Ca = 420 ppm = 0.042%
Ca = 280 ppm = 0.028 %
Your way of calculation its only a decrease with 0.014 % - does this "minor" thing matter for stony corals or not?
Alkalinity 7.0 dKH (125 mg CaCO3/L = 125 ppm CaCO3) = 0,0125%
Alkalinity 4,66 dKH (83 mg/L CaCO3 = 83 ppm CaCO3 = 0,0083%
Your way of calculation its only a decrease with 0.0042 % - does this "minor" thing matter for stony corals or not?
Natural saltwater Copper concentration 1-3 µg/L = 1-3 ppb = 0.001-0.003 ppm = 0.000001-0.000003 %
Toxic Copper concentration in saltwater for corals - around 20-50 µg/L = 20-50 ppb = 0.020 - 0.050 ppm = 0.00002 - 0.00005 %
Your way of calculation its only a increase with around 0.000047 % - does this "minor" rise matter for stony corals or not?
Even if you rise Cu concentration to 1-2 ppm (kill ich) Your way of calculation its only an increase with 0.000197 % - is it harmfull or not?
Concentration is a good way to measure potential harmfull (or beneficial) compounds - the outcome is Independent regardless of whether the current concentration (expressed as ppm, ppb, mg/l, % or so on) is in a liter or in the entire ocean (or a room compared with the atmosphere).
I honestly don't think he was ignorant to grade school math rather he didn't want to concede and attempted some mental gymnastics in an effort to prove the counter point right.
I´m sorry to say - but I think it is more worse than that. He/she knows all of this things but his/hers post is an attempt to create fog curtains around the real question - does a concentration of 420 ppm CO2 cause the damage that a largely unanimous body of active scientists claims or not?
This post is interesting - my bold - by the way - I found this post with help of research of the R2R website
I see this word thrown around all the time. I want to open a discussion on the reality of this word in order to better understand what people know about the scientific method. My wife is currently "researching" kitchen counter tops... I am a scientist by education and profession (my wife is a freshwater biologist and certified emeritus ecologist).
The question is:
What is "Research"?
