Question 3: How much more acidic are our oceans today? 
No change 
No, more than 26% is the right answer. This speed of ocean acidification is also the fastest recorded in the past 65 Million years! According to the United Nations IPCC report: “Ocean acidification is quantified by decreases in pH. The pH of ocean surface water has decreased by 0.1 since the beginning of the industrial era (high confidence), corresponding to a 26% increase in hydrogen ion concentration.”
 
5% more acidic today 
No, more than 26% is the right answer. This speed of ocean acidification is also the fastest recorded in the past 65 Million years! According to the United Nations IPCC report: “Ocean acidification is quantified by decreases in pH. The pH of ocean surface water has decreased by 0.1 since the beginning of the industrial era (high confidence), corresponding to a 26% increase in hydrogen ion concentration.”
 
11% more acidic today 
No, more than 26% is the right answer. This speed of ocean acidification is also the fastest recorded in the past 65 Million years! According to the United Nations IPCC report: “Ocean acidification is quantified by decreases in pH. The pH of ocean surface water has decreased by 0.1 since the beginning of the industrial era (high confidence), corresponding to a 26% increase in hydrogen ion concentration.”
