World’s oceans hottest ever in 2022, study shows

ANKARA – The world’s oceans were at their hottest ever on record in 2022, according to a new study.

“The Earth’s energy and water cycles have been profoundly altered due to the emission of greenhouse gases by human activities, driving pervasive changes in Earth’s climate system,” reads the report by an international group of scientists published in the Advances in Atmospheric Sciences journal.

Warming of oceans has led to “more extreme weather … and that has tremendous consequences all around the world,” said John Abraham, a professor at the University of St. Thomas in the US who was part of the study team.

Using records kept since 1958, the analysis determined that there has been an “inexorable rise in ocean temperature, with an acceleration in warming after 1990,” British daily The Guardian reported.

As oceans absorb over 90 percent of the excess heat created by greenhouse gas emissions, ocean warming and its effects on extreme weather will increase until humanity approaches net zero emissions, the report said.

The findings build on a World Meteorological Organization (WMO) report last October, which showed that the atmospheric concentration of the three main greenhouse gases – carbon dioxide, methane and nitrous oxide – all hit record highs in 2021.

The data on the “continuing rise in concentrations of the main heat-trapping gases, including the record acceleration in methane levels, shows that we are heading in the wrong direction,” said WMO head Petteri Taalas. (Anadolu)
