Our world is getting warmer - not only the atmosphere, but also the oceans. The past ten years have brought the highest temperatures in the oceans since the 1950s, an international team of scientists reports in the journal "Advances in Atmospheric Sciences". The most recent five years have been the warmest in each case.
2019 was therefore the year with the highest water temperature recorded in the ocean since measurements began. The sea temperature down to a depth of two kilometres was about 0.075 degrees above the average from 1981 to 2010, according to the paper, which was written by Cheng Lijing of the Institute of Atmospheric Physics (IAP) at China's Academy of Sciences (CAS). The researchers also point out that climate change is accelerating the warming of the oceans.
Record-Setting Ocean Warmth Continued in 2019
Water is a denser thermal medium than air, so it might be good if the quantity of total heat stored in the warmed ocean water was published in addition to the temperature change.
Water whose temperature is only slightly warmer can add a lot more heat to the atmosphere in the form of increased water vapor that will rise off the water due to its higher temperature.
Really we need more explanation of how the heat taken up in the oceans is distributed further into atmospheric water vapor and deeper ocean thermal currents, as well as what happens to those thermal currents within the oceans.
It is easy for people to assume that the oceans are giant and thus that any extra heat absorbed by them will just disappear, but like the atmosphere, the oceans must have climatological patterns that should be understood fully in order to predict the long-term effects of continually adding heat/CO2 to them.
