Or maybe they're referring to a future pH < 7 state, but I read recently something to the effect that a doubling of atmospheric CO2 over the next 100 yrs would only reduce the pH of the oceans by 0.24, so we'd be talking way, way into the future (if ever) before pH < 7 conditions should exist.

It presents a significant reinterpretation of the region's recent climate change origins, showing that atmospheric conditions have changed substantially over the last century, that these changes are not likely related to historical anthropogenic and natural radiative forcing, and that dynamical mechanisms of interannual and multidecadal temperature variability can also apply to observed century - long trends.

While the conditions in the geological past are useful indicators in suggesting climate and atmospheric conditions only vary within a a certain range (for example, that life has existed for over 3 billion years indicates that the oxygen level of the atmosphere has stayed between about 20 and 25 % throughout that time), I also think some skeptics are too quick to suggest the lack of correlation between temperature and CO2 during the last 550 million years falsifies the link between CO2 and warming (too many differences in conditions to allow any such a conclusion to be drawn — for example the Ordovician with high CO2 and an ice age didn't have any terrestrial life).
