Where the oceans have been colder & hotter than average
Record high annual mean surface temperatures (2015)
Since 1955, more than 90 percent of the excess heat retained by the Earth as a result of increased greenhouse gases has been absorbed by the oceans.
Estimated heat accumulation
For several decades, more energy has been absorbed than emitted at the top of Earth’s atmosphere. According to Gregory Johnson, an oceanographer at NOAA, the rate of energy gained between 1971 and 2010 was roughly equal to the power required to run 140 billion 1,500-watt hair dryers over the same number of years. The rate has only increased in the past decade.
