You had never left. You simply went into a cowardly retreat and lurked ... until something riled your religious sensitivities enough to compel you to post again.

In this case my non-acceptance of your fear-mongering hype was too much for you to bear. You felt your faith being put in jeopardy and you lashed out. I get it.

There is no bleach involved in coral expelling algae

and there is no "ocean acidification."

"The acidity of any solution is determined by the relative concentration of hydrogen ions (H+). A larger concentration of H+ ions in a solution corresponds to higher acidity, which is measured as a lower pH.

At present seawater is extremely rich in dissolved carbonate minerals. However, as ocean acidity increases, carbonate ion concentrations fall.
The absorption of CO2 largely results from the dissolution of the gas into the upper layers of the ocean, but CO2 is also brought into the oceans through photosynthesis and respiration. Algae and other marine photosynthesizers take in CO2 and store it in their tissues as carbon. Carbon is then passed to zooplankton and other organisms through the food chain, and these organisms can release CO2 to the oceans through respiration. In addition, when marine organisms die and fall to the ocean floor, CO2 is released through the process of decomposition."

The term 'fossil fuel' is well propagandized that is true. That doesn't make fuel a fossil, or fossils fuel.

So are you saying an **** is a pothole left in the street by too much traffic with people and their asses?

Or are potholes really made by pots?

You should alert Brittanica to this error.

Fossils don't burn. Burning any fuel that happens to contain carbon does produce carbon dioxide.

Most carbon dioxide simply stays dissolved in the water. That also returns to the air. A small amount turns into carbonic acid. This is necessary for shellfish to survive, since it is this acid that erodes calcium deposits on the ocean floor into solution, making calcium available for shellfish to build their shells.

Not permanently. It is used up in the process of helping shellfish survive.

Redefinition: acidification. This is NOT the definition of acidification. You cannot acidify anything unless it is neutral or acid already. You cannot acidify an alkaline.

I suggest you look up the meaning of pH.

To acidify something is to... make it more acidic.

That's the word. Fossil fuels are fuels derived from ancient organisms. If you'd like to go on a word-crusade, do it somewhere else.

So your objection is moot - humans are indeed putting CO2 into the atmosphere.

Some amount of carbonic acid is useful, yes! Good point! But too much can be bad.

I never said that all of the carbon dioxide was turned into carbonic acid, just that increased atmospheric CO2 levels are correlated with a decrease in oceanic pH.

...do you have a source for that? For the shellfish to 'absorb' this much carbonic acid, the carbonic acid level would need to be a limiting factor on the shellfish population, and food and habitat size would need to be negligible. This seems... unlikely.

I know what pH is - it's a measure of the acidity/alkalinity of a solution. It's based on the concentration of H+ ions IIRC.

Dealkanization is a mouthful, so we say acidification, because one definition of the latter is:

"Bleach: whiten by exposure to sunlight or by a chemical process"
"deprive of vitality or substance"

Coral bleaching is the process of turning coral reefs white by increasing the temperature of the seawater. Either you're an idiot or you're incompetent, because "there was no bleach" is not a refutation of any sort. (Or you're a troll.)

Ugh, could you get off your high horse for just a few minutes? It's quite tiring.

Oh? What's that you say? Why'd we call it coral bleaching then? Good question! (I mean, it's not actually that good of a question... it's like "how come there's no greenhouses involved in the GHE", but I won't complain. Assuming good faith and whatnot.)

In its usual or mundane sense, to "bleach" is to whiten clothing. The word comes from the Old English word "blǣc" (that's similar to blaec, if it doesn't show up), which means "pale". It is etymologically similar to the word "bleak", meaning barren, desolate, stark; cold, miserable; or forbidding.

The chemical referred to as "bleach" is either sodium hypoclorite or hydrogen peroxide. These were developed in the 18th century, but the bleaching process, using either chemicals or the Sun, has been known and used for millenia.

We can generalize the first definition to whitening of any object due to either a chemical process or the Sun. From there, we can further generalize to whitening in general.

Coral bleaching is the expulsion or loss of algal pigments from coral. Since this algae produces roughly 90% of the coral's energy, bleached corals eventually die from lack of energy, usually. Needless to say, this is not good. However, I will say it, because you might not know that.

Coral bleaching can be caused by increasing oceanic temperatures, which has been measured by the NOAA.


See? Temperature measurements.

and there is no "ocean acidification."

There does indeed exist the phenomenon of decreasing oceanic pH. The pH is still above 7 (that means it's still basic), but it is getting closer to 7 (it is becoming less basic) over time.

Which of the following statements do you deny?

1. Humans have burned significant amounts of fossil fuels.
2. The burning of fossil fuels produces carbon dioxide.
3. Carbon dioxide, in the presence of water, results in the production of carbonic acid in the water.
4. Carbonic acid, when placed into seawater, results in the pH of said water decreasing.
5. This phenomenon is known as ocean acidification.
