The question for policy-makers and society is “Will the ocean continue to take up anthropogenic CO2?” Our best evidence is that it will—but less effectively because of interactions between the ocean and the evolving climate.
Several factors come into play. Global warming will inevitably cause seawater temperatures to rise. Warmer water holds less dissolved gas than colder water, so the ocean will not be able to store as much anthropogenic CO2.
A warmer climate will also melt ice and increase rainfall near the poles, adding fresh water to the ocean. Fresh water is more buoyant than saltier water and “floats” on top of it, stratifying the ocean and slowing the mixing and circulation that transports anthropogenic CO2 away from the surface and into reservoirs in the deep ocean. The net effect will be even higher atmospheric CO2 concentrations and a further acceleration of global warming.

➔ Global Warming
Warmer temperatures, weaker circulation, and different stratification of the ocean will have impacts on marine life and ecosystems, which in turn could affect the ocean’s ability to store carbon. How these changes may occur is not clear at this point, however, and may vary from region to region.
A more acidic ocean
The increasing amount of carbon in the ocean will cause another problem for marine life: ocean acidification. The 3-percent increase in dissolved carbon in surface water may seem small, but it is enough to significantly alter the chemistry of seawater and threaten whole groups of marine life.
The reason involves some basic chemistry. When CO2 gas dissolves in seawater, it combines with water molecules (H2O) to form carbonic acid (H2CO3). The acid releases hydrogen ions into the water. The more hydrogen ions in a solution, the more acidic it becomes.
Hydrogen ions in ocean surface waters are now 25 percent higher than in the pre-industrial era.

How else do you learn? Is THIS your study forum? Do you talk to your chickens and cows? How do you know what's real and what isn't. Wow...where are you people from? Mars?
