In particular,
if ocean acidity were a problem for shell formation, it would have shown up already in areas where there are naturally high levels of CO2.
Not exact matches

if least publicized, environmental threats: the rising
acidity of the
oceans.

One can logically wonder at just how much Dr. Dorney knows
if he begins his testimony with «Today the surface
ocean is almost 30 % more acidic than it was in pre-industrial times, and over the next few decades, the level of
acidity of the surface
ocean will continue to rise...» when the worries about acidic
oceans is pointless since where is the base line?
It also means monitoring the
acidity of
oceans to see what effect,
if any, changes will have on the global seafood industry.

The
ocean's absorption of anthropogenic CO2 has already resulted in more than a 30 % increase in the
acidity of
ocean surface waters, at a rate likely faster than anything experienced in the past 300 million years, and
ocean acidity could increase by 150 % to 200 % by the end of the century
if CO2 emissions continue unabated (Orr et al. 2005; Feely et al. 2009; Hönisch et al. 2012)
So I am forced to appeal to authority —
if scientists in credible, peer - reviewed journals take (i) or (ii) to be knocked down, then I'll stop advocating for a lower carbon future (er,
if increased
ocean acidity is shown not to be a problem).
Now scientists are setting up to learn more about how our
oceans are reacting to the 30 % increase in pH (the measure of
