Ocean Warming Accelerates Faster Than Scientists Expected

The fact that the oceans are warming is no breaking news. We all know that climate change is affecting the planetary clime and triggers extreme weather phenomena. The scientists reached that conclusion thanks to about 4,000 buoys deployed in the oceans since 2000 that have measured more ocean warming since 1971 than the UN latest estimates, from 2013, revealed.

“Observational records of ocean heat content show that ocean warming is accelerating,” said the scientists from China and the United States in the journal Science. Human-made greenhouse gas emissions are still heating up the Earth’s atmosphere, and the majority of that heat goes into the oceans, as the scientists revealed in recent studies.

“Global warming is here and has major consequences already. There is no doubt, none,” the scientists said in their new study on ocean warming. “2018 was the warmest year on record for the global ocean, surpassing 2017,” added the research leading author, Lijing Cheng at the Institute of Atmospheric Physics at the Chinese Academy of Sciences.

Ocean Warming Accelerates Faster Than Scientists Expected

Lijing Cheng also told Reuters that “records for ocean warming had been broken almost yearly since 2000.” In reality, the oceans’ temperature, at waters down to 2,000 meters, reached a 0.1 degrees Celsius increase between 1975 and 2010. The same trend is continuing nowadays, the researchers warned in other studies.

In the same direction, the European Union’s Copernicus Climate Change Service estimated that 2018 had been the hottest year regarding global surface temperature. As a consequence, ocean warming has also accelerated faster than scientists expected. “The deep ocean reflects the climate of the deep and uncertain past,” explained Kevin Trenberth, a researcher at the US National Center for Atmospheric Research, and the co-author of the new study.

Ocean warming is reducing the levels of oxygen in the oceans and affects the coral reefs around the world. Along with other extreme weather phenomena, the warming of oceans is one of the most damaging things for life on Earth.
