With a little bit of research on your own you can find out for yourself that this is an incredibly important issue that affects everyone on the planet, and there is nothing "sensational" about the way it is reported.

Yet you seriously haven't included any links to this easy to find research the we are at an all time acidification high in 300 million years?

Pretty sure the title might actually get it right unlike the actual article "Ocean acidification due to carbon emissions is at highest for 300m years"

It is the rate of acidification, not the acidification itself that is high.

Not really sure what your point is here. But anyway, here is the link to the report: http://www.stateoftheocean.org/research.cfm

Listed in the Guardian's article. Peer reviewed source material is at the bottom of each of the reports.
