Silly, unserious people deny this is happening

 

Ocean acidification is happening. It has to be. The oceans are continuing to absorb more CO2, which has kept atmospheric concentrations lower than if they weren't doing that, but by absorbing it, they become more acidic. That's basic seawater chemistry.

And it's getting worse, of course. But how much worse is somewhat scary.

World's oceans close to becoming too acidic to sustain marine life, report says

A new report by the Potsdam Institute for Climate Impact Research details how a crucial threshold for ocean acidification could soon become the seventh factor breached – out of of nine – considered critical for the planet's ability to regulate life-sustaining natural systems. The growing acidification of the planet's oceans is due to ever-increasing emissions of carbon dioxide released by burning fossil fuels, which the oceans then absorb.

"Acidic water damages corals, shellfish and the phytoplankton that feeds a host of marine species. This means it also disrupts food supplies for billions of people, as well as limiting the oceans' capacity to absorb more CO2 and thus help limit global warming."

It constantly amazes me (and distresses me, so much that I've given up engaging with some of the more ludicrous deniers) that people can deny this is happening. But they do.
