Is Ocean Acidification from Rising Carbon Dioxide a Grave Threat?

‘Global warming’ is in the news almost daily these days, but rarely do we hear about its ‘evil twin’ or ‘the other carbon dioxide (CO₂) problem’, viz. ocean acidification. Global warming, caused mainly by anthropogenic CO₂ emissions, is apparently accompanied by ocean acidification, which is another major growing global problem with continued increase in atmospheric CO₂ levels. While there is large uncertainty in the detection and attribution of climate warming because of the large natural variability in surface temperatures, ocean acidification is relatively a certain and straight forward consequence of rising atmospheric CO₂.
