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 (CO 2 ) problem’, viz. ocean acidification. Global warming, caused mainly by anthropogenic CO 2 emissions, is apparently accompanied by ocean acidification, which is another major growing global problem with continued increase in atmospheric CO 2 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 CO 2 .
