This statistic represents annual anomalies in global ocean surface temperature from 1880 to 2018, based on temperature departure from the 20th century average. In 2018, ocean surface temperatures were around 0.66 degrees Celsius warmer than the 20th century average. Oceans are responsible for absorbing over 90 percent of the Earth's excess heat from global warming.
