How does climate change effect the ocean?

The world’s oceans have absorbed 93% of human-induced warming since the 1970s. This has contributed to more than 80% of sea level rise between 1993 and 2010 and led to an increase in the uptake of carbon dioxide, resulting in a subsequent increase in ocean acidity. The pH of the ocean’s surface is believed to have decreased by 0.1 pH units since the beginning of the industrial age, while overall ocean acidity has increased by 30% in 50 years.
