Another example of not telling the whole story: The standard Green/Left deception technique
It's difficult to know where to start on commenting on the scare below but let me start by noting that an increased level of CO2 absorption by water is a sign of COOLING -- carefully not mentioned below. And because there are great uncertainties in measuring ocean temperatures exactly that could be going on.
OK. Next point. If CO2 levels in the ocean are "too" high, global warming will cure it. Because warming water will cause the CO2 to outgas. Just open a can of coke or Pepsi while it is at room temperature and watch it happen. So global warming will cure the "problem", not worsen it
Point 3: There are plenty of studies showing that crustaceans and shellfish are not affected by acidity in the simple way Warmists assume. They can in fact flourish in a more acid environmrent. See here and here.
Point 4: The oceans are quite alkaline and it would take a huge change to make them acidic. Measured in the open ocean, sea water has a pH of about 8.2. According to computer models, doubling of atmospheric CO2 would decrease ocean pH to about 7.9, still alkaline, but less so.
The North Atlantic absorbed 100 percent more man-made carbon dioxide over the last decade, than the previous one, researchers have found.
They say the find is a clear indication of the impact burning of fossil fuels has had on the world’s oceans in just 10 years.
The uptake of CO2 has massive impacts on the ocean's ecosystem, by decreasing the pH, and could affect as corals and mollusks, which require a certain pH level in the surrounding water to build their calcium carbonate-based shells and exoskeletons.
“This study shows the large impact all of us are having on the environment and that our use of fossil fuels isn’t only causing the climate to change, but also affects the oceans by decreasing the pH,” said Ryan Woosley, a researcher in the UM Rosenstiel School, Department of Ocean Sciences who led the research.
Decreasing pH in seawater can harm the ability of shelled organisms, from microscopic coccolithophores to the oysters and clams that show up on our dinner plates, to build and maintain their bony exteriors.
Burning oil, coal, and natural gas for energy, along with destruction of forests, are the leading causes of the carbon dioxide emissions
The amount of carbon dioxide in the atmosphere has risen from 355 parts per million in 1989 to just over 400 ppm in 2015. [Quibble: Cape Grim has the level just under 400ppm]
To determine the total uptake and storage of carbon dioxide in the North Atlantic over the last several decades, researchers analyzed data collected from the same locations, but 10 years apart, to identify changes caused by man-made CO2.
The data were collected during two National Science Foundation-funded international ship-based studies, CLIVAR (Climate Variability CO2 Repeat Hydrography) and GO-SHIP (Global Ocean Ship-Based Hydrographic Investigations Program).
The oceans help to slow the growth of human produced CO2 in the atmosphere by absorbing and storing about a quarter of the total carbon dioxide emissions.
The researchers hope to return in another 10 years to determine if the increase in carbon uptake continues, or if, as many fear, it will decrease as a result of slowing thermohaline circulation.
The study, titled “Rapid Anthropogenic Changes in CO2 and pH in the Atlantic Ocean: 2003-2014” was published in the journal Global Biogeochemical Cycles.
