The article does not link to any peer review studies to prove it's point, which to me means it's probably bunk, taking a know issue and enlarging it to sensationalise.
And it's sad people fall for this.
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.
Listed in the Guardian's article. Peer reviewed source material is at the bottom of each of the reports.
(If the seas do have an ecological crash which makes the remaining eco systems go down, then any surviving Green party members will probably argue the advantage of this, pushing their carts down "The Road".)
So, no hope. :-) :-(
Yeah, it doesn't generate CO2. But at least you can live in a hotter world, can't live with nuclear waste/fallout.
(Also, we don't know that a hotter climate is bad, we've never tried it before)
To make Chernobyl comfortable for people, a cleaning effort is needed, but it's of manageable size.
