Point #1...your idiot link neglects to mention that the majority of life in the ocean evolved during a time when atmospheric CO2 was about 10 times what it is today...and even then the oceans were not acidic....acidic sea water is a myth...it will never happen...the ocean can become less alkaline...but never acidic...the ocean acidification myth is just more hysterical handwaving on the part of idiot alarmists...

"When water (H2O) and CO2 mix, they combine to form carbonic acid (H2CO3). Carbonic acid is weak compared to some of the well-known acids that break down solids, such as hydrochloric acid (the main ingredient in gastric acid, which digests food in your stomach) and sulfuric acid (the main ingredient in car batteries, which can burn your skin with just a drop). The weaker carbonic acid may not act as quickly, but it works the same way as all acids: it releases hydrogen ions (H+), which bond with other molecules in the area.
Seawater that has more hydrogen ions is more acidic by definition, and
it also has a lower pH. In fact, the definitions of acidification terms—acidity, H+, pH —are interlinked: acidity describes how many H+ ions are in a solution; an acid is a substance that releases H+ ions; and pH is the scale used to measure the concentration of H+ ions.
The lower the pH, the more acidic the solution. The pH scale goes from extremely basic at 14 (lye has a pH of 13) to extremely acidic at 1 (lemon juice has a pH of 2), with a pH of 7 being neutral (neither acidic or basic). The ocean itself is not actually acidic in the sense of having a pH less than 7, and it won’t become acidic even with all the CO2 that is dissolving into the ocean. But the changes in the direction of increasing acidity are still dramatic.
So far, ocean pH has dropped from 8.2 to 8.1 since the industrial revolution, and is expected by fall another 0.3 to 0.4 pH units by the end of the century. A drop in pH of 0.1 might not seem like a lot, but the pH scale, like the Richter scale for measuring earthquakes, is logarithmic. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. If we continue to add carbon dioxide at current rates, seawater pH may drop another 120 percent by the end of this century, to 7.8 or 7.7, creating an ocean more acidic than any seen for the past 20 million years or more."
Point #2....warmer oceans outgas more than they take up...cold water holds more CO2 than warm water...open two cans of soda...one room temperature...one from the refrigerator...put the warm one on the counter..and the cold one back in the refrigerator...taste them tomorrow...you will see that the warm one is flat as a pancake...so it lost its CO2...the cold one while it will be less fizzy than when freshly opened will still be bubbly....if the oceans are warming then there is no danger of them becoming less alkaline as they are outgassing...if they are becoming cooler, then the AGW scam is proven to be a scam...how could the oceans be cooling if the earth is warming?
Refer to Henry's law...it states that the concentration of gas in liquid is proportional to the gas in equilibrium above the liquid...Henry's law assumes a constant temperature...if the temperature changes, then the rate and level of absorption changes...if the oceans warm, then they outgas...if they cool, then they take up CO2...
Nice copy and paste. Where did you get it from?

Box 3.4: Causes of glacial/inter-glacial changes in atmospheric CO2.
"One family of hypotheses to explain glacial/inter-glacial variations of atmospheric CO2 relies on physical mechanisms that could change the dissolution and outgassing of CO2 in the ocean. The solubility of CO2 is increased at low temperature, but reduced at high salinity. These effects nearly cancel out over the glacial/inter-glacial cycle, so simple solubility changes are not the answer. Stephens and Keeling (2000) have proposed that extended winter sea ice prevented outgassing of upwelled, CO2-rich water around the Antarctic continent during glacial times. A melt-water �cap� may have further restricted outgassing of CO2 during summer (François et al., 1997). These mechanisms could explain the parallel increases of Antarctic temperature and CO2 during deglaciation. However, they require less vertical mixing to occur at low latitudes than is normally assumed. The relative importance of high and low latitudes for the transport of CO2 by physical processes is not well known, and may be poorly represented in most ocean carbon models (Toggweiler, 1999; Broecker et al., 1999)."
Point #3...your hysterical 30% more acidic amounts to 0.1 pH unit less alkaline than it was during pre industrial times...proxy studies indicate that the ocean pH has varied from 7.91 to 8.29 during the past 7000 years....that puts the natural cyclic variation more than 4 times larger than the 0.1 pH unit you seem to be so worried about.

Point #4...there is no evidence that the oceans were ever acidic during the past 500 million years even when atmospheric CO2 was in excess of 6500ppm..this tells us that there is yet another controlling factor...namely the buffering action of basalt rocks on the ocean floor...when the ocean runs out of rocks, start worrying...till then hysterical handwaving doesn't make alarmism true.
None of the articles I have used has declared that atmospheric CO2 causes the acidification of the oceans save for increasing the temperatures of the oceans leading to more absorption of CO2. What you need to do is to try and undestand the definition of "acidic" as used in reference to the oceans which simply means less alkaline.
