The total heat content of the world’s oceans (OHC) in 2019 was the warmest in recorded human history, according to a paper published in Advances in Atmospheric Sciences.
More than 90% of the increasing heat from human-caused global warming accumulates in the ocean because of its large heat capacity.
“We found that 2019 was not only the warmest year on record, it displayed the largest single-year increase of the entire decade, a sobering reminder that human-caused heating of our planet continues unabated,” said Penn State’s Dr. Michael Mann, one of the co-authors. The gain in ocean heat between 2018 and 2019 was about 44 times as great as all the energy used by humans in one year.
