Oceans heating up faster than expected, set record in 2018 - Al Jazeera English Al Jazeera English - Fri 11 Jan 05:55 GMT
Scientific findings raise new concerns about the pace of climate change and its effect on marine life and sea levels.
The world's oceans are heating up at an accelerating pace and faster than previously estimated, setting a new temperature record in 2018 as global warming threatens a diverse range of marine life, scientists have warned.
Man-made greenhouse gas emissions are warming the atmosphere, according to the overwhelming majority of climate scientists, and a large part of the heat gets absorbed by the oceans.
And if nothing is done to reduce greenhouse gases, "models predict that the temperature of the top 2,000 metres of the world's oceans will rise 0.78 degrees Celsius by the end of the century", it said.

Lead author Lijing Cheng, of the Institute of Atmospheric Physics at the Chinese Academy of Sciences, said records for ocean warming had been broken almost yearly since 2000.
A separate study on Monday, by the European Union's Copernicus Climate Change Service, said 2018 was the fourth warmest year for global surface temperatures in records dating back to the 19th century.
