Recent ocean rise in temperature sets a new record

According to a report from an international group of researchers on Jan. 13, 2019 in the journal Advances in Atmospheric; In 2019, the ocean temperature was about 0.135 degrees Fahrenheit (0.075 degrees Celsius) higher than the average between 1981 and 2010, which implies that the ocean — which absorbs almost all of the greenhouse gases humans spew into the atmosphere — has taken in 228 sextillian (228,000,000,000,000,000,000,000) joules of heat above its average.

The amount of heat we have put in the world’s oceans in the past 25 years equals to 3.6 billion Hiroshima atom-bomb explosions,” lead author Lijing Cheng, associate professor with the International Center for Climate and Environmental Sciences at the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS), said in the statement.

To analyze temperature changes in the oceans, Cheng and the team used all of the available data — measured from a number of different devices, including 3,800 drifting so-called Argo floats scattered across the oceans — published by the World Ocean Database and the National Oceanic and Atmospheric Administration. All of the measurements were taken between the surface of the water and a depth of 6,562 feet (2,000 meters).

They compared data taken between 1987 and 2019 with that taken from 1955 to 1986 and found that the oceans warmed 450% more in the more recent time stint than in the earlier bracket, according to the statement. The ocean has been the warmest in the past 10 years than it’s been since measurements were first taken in the 1950s.
