NOAA, The National Oceanic and Atmospheric Administration, reports [*] on the discovery, published in Nature Climate Change (full article is pay-walled):
[...] that between the 1990s and 2010, acidified waters expanded northward approximately 300 nautical miles from the Chukchi Sea slope off the coast of northwestern Alaska to just below the North Pole. Also, the depth of acidified waters increased from approximately 325 feet below the surface to more than 800 feet.
The United Nations Development Programme explains that
[...] since gases such as CO2 dissolve more readily in colder water, ocean acidification will progress – already is progressing – much more rapidly in the Arctic and Antarctic, where a number of species are already facing challenges in fixing their shells. Under a lower pH ocean future, increasing numbers of calcium carbonate fixing organisms could face dramatic losses or even extinction.

Really dumb generalization you've got there. I don't like tax payer funded research being paywalled, but it doesn't mean it is a lie. If it was a lie I would expect the paper to be free so it could sway public opinion with its dubious research. We already know that blatant lies and shoddy research make it into the news cycle with hardly any problems, and peer review does not really matter unless it is a big enough lie that the debunking becomes newsworthy.
