No alarmism and hysteria is shrill enough for the demagogues of global warming and climate change! As usual this alarmism is based among other things on computer model simulations (a great tool for demagogues)!
CO2 is a minuscule atmospheric, life essential trace gas (about 400-450 ppm [parts per million])! To acidify the oceans there would probably need to be a lot more CO2 in the atmosphere than currently.
Carbonic acid is also very unstable. It constantly breaks down again.
As usual such nonsense is spread by the American Association for the Advancement of Science (AAAS). Every time, the AAAS does this it is shocking!
Apparently, the NOAA’s Pacific Marine Environmental Laboratory (PMEL) is also actively involved in this demagoguery (see e.g. this video on YouTube)! President Trump are you listening! Please, fire these ideologues!
We still know very little about our oceans to make such outrageous claims! Plant some more trees and be happy!
"Climate change’s ‘evil twin’ is much worse than we thought
...
As human activities continue to pump carbon dioxide into the atmosphere, more and more of the stuff gets absorbed into Earth’s oceans, where it reacts with seawater to form carbonic acid. When this weak acid dissociates into ions of hydrogen and bicarbonate, it drives down the ocean’s overall pH, which is typically slightly basic.
This acidification—sometimes referred to as climate change’s “evil twin”—can wreak havoc on marine life, for example by interfering with the mineralization process that corals, oysters, and other organisms use to build and maintain their skeletons and shells.
A 2014 video released by the National Oceanic and Atmospheric Association’s Pacific Marine Environmental Laboratory (NOAA PMEL), for instance, shows a marine snail called a pteropod struggling to swim, its shell having been partially dissolved by acidic waters. ...
According to a new study, however, the situation is more dire than anyone anticipated. Drawing on measurements from ice cores, computer models, and studies of marine life, scientists developed an assessment of the last 150 years. The “boundary” for ocean acidification, the team reports in Global Change Biology, was actually crossed five years ago . And the deeper researchers delved beneath the ocean’s surface, the worse the problem became: At 200 meters down, 60% of global waters had breached the limit for “safe” acidification, compared to over 40% of the surface ocean. The findings suggest that, when it comes to protecting vulnerable marine ecosystems, humanity is already running out of time. “Ocean acidification isn’t just an environmental crisis—it’s a ticking time bomb for marine ecosystems and coastal economies,” ...
The impacts on marine life are far-reaching. Research published earlier this year in Environmental Science & Technology found, for instance, that changes in ocean chemistry could be shifting male-female ratios in populations of oysters, which rely on environmental cues to determine their sex.
Oysters exposed to more acidic conditions, researchers reported, were more likely to have female than male offspring—a shift that could affect oyster reproduction and population dynamics for generations, both in hatcheries and in the wild. According to a recent study published in the Proceedings of the National Academies of Science, increased ocean acidity could also harm populations of carbon-eating phytoplankton. This effect could potentially cause additional increases in atmospheric carbon dioxide, thus speeding up global climate warming. ..."
