Climate scientists said preliminary data from the National Oceanic and Atmospheric Administration (Noaa) showed the average temperature at the ocean’s surface has been at 21.1C since the start of April – beating the previous high of 21C set in 2016.
“The current trajectory looks like it’s headed off the charts, smashing previous records,” said Prof Matthew England, a climate scientist at the University of New South Wales…
According to the Noaa data, the second-hottest globally averaged ocean temperatures coincided with El Niño that ran from 2014 to 2016.
The data is driven mostly by satellite observations but also verified with measurements from ships and buoys. The data does not include the polar regions. More than 90% of the extra heat caused by adding greenhouse gases to the atmosphere from burning fossil fuels and deforestation has been taken up by the ocean. A study last year said the amount of heat accumulating in the ocean was accelerating and penetrating deeper, providing fuel for extreme weather.
England, a co-author of that study, said: “What we are seeing now [with the record sea surface temperatures] is the emergence of a warming signal that more clearly reveals the footprint of our increased interference with the climate system.”
