If present trends continue,the ocean's surface waters will be ______ more acidic by 2100 than they were in 1800.

Question

Quizplus · Accepted Answer

The current rate of increase in ocean acidity is about 0.1 pH units per decade, or 0.4 units since pre-industrial times (around 1800). If present trends continue, by the year 2100, the pH of the ocean's surface waters is projected to decline by a further 0.3 to 0.5 units. This means that the ocean's surface waters will be 150% more acidic than they were in 1800 (i.e. 1.5 times more acidic). Therefore, the correct answer is D)150%.

If Present Trends Continue,the Ocean's Surface Waters Will Be ______
