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.

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.

You are correct. CO2 is less soluble in warmer water, so at some point the oceans will cease to be carbon sinks. This is a major potential climate change tipping point, because currently the oceans are an absolutely massive CO2 sink.

The melting of freshwater will indeed also inhibit the transportation of CO2 into the depths of the oceans.

These are pretty basic and well-known scientific concepts, but I suppose if one can't grasp the basics of the greenhouse effect, it's not surprising that they can't comprehend these simple processes either.

There are other mechanisms for CO2 to be released from warming ocean waters. The beaches of Bermuda are composed of Oolites of precipitated calcium carbonates in the warm waters there. These precipitate because calcite is less soluble in warm water. Anyway, the gloom and doom scenarios of warming waters releasing all sorts of dangers such as methane hydrates and bottled up CO2 has not happened in the past to a significant extent except as the lag time previously discussed. Because there is a lag time, this indicates that CO2 is not the driver in climate change. The scare scenarios of the left are predicated on something that has not been shown to be a cause. Instead, it has been shown to result from temperature changes.

What you are referring to is a "lag time" between CO2 concentrations and temperature increases then planet correction. You are wrong on the oceans ability to continue to absorb CO2, the oceans are a sink to a point, but that sink will get full. Lastly is the upwelling theory where CO2 concentrations are being stored in the depths of the oceans in cold water and as the surface temperatures rise it could cause the oceans to flip, releasing large amounts of CO2.
How come it is, that the two who claim to be doctors know **** about nothing. Hell Dr. T can't even read a simple chart.
Yeah so to sum it up, we are really ******* it up bad, except according to Texas as reported on NPR this morning.

And how, then, Progenitor of All Women, do historical global temperatures always fall precipitously in the presence of the highest levels of CO2 if CO2 causes global warming?

Yea - First you "study" "global warming". You make all sorts of doom and gloom speeches and writings about it.

When none of your doomsday scenarios come true, you find some way to say it's happening, something else is covering just how bad it "really" is, and we're all more doomed today then we were last year!

And sometime in the future, something else will be blamed for nothing happening, and that will be proof that we're all doomed!

[Edit] We know what's real and what's not by using objective science. This is when the facts speak for themselves without the need for any specialized education, or indoctrination to verify the results. When someone says that a 'consensus' claims something is true, it usually isn't. Science doesn't need to be voted on to determine if it is real.

hi..i have study the causes of global warming..i think now the global warming is happen but not many people have know it..this happen because first it from people that not irresponsible for the nature..this kind of people can destroy the earth slowly and slowly...now the earth is getting hotter because they cutting the tree at forest without thinking good or bad..they always think about benefits..tree is the important because tree gives people,animal and many more a oxygen..to live..that's all...byeee

Weren't the 5 warmest years recorded in the years just before World War 2. I heard that last night. maybe somebody could confirm that for me.
