Lijing Cheng also told Reuters that "records for ocean warming had been broken nearly yearly since 2000".

Researchers said this showed that, contrary to the claims of some sceptics, the world was warming at a...

The latest technology shows no such hiatus ever existed, raising new concerns about the pace of climate change and its effect on the planet's main buffer - the oceans.

"It's mainly driven by the accumulation of greenhouse gases such as carbon dioxide in the atmosphere due to human activities", Lijing said.

Evidence from the new testing in four independent groups now suggest a stronger observed Heat Ocean Content warming, the journal states, with all four recent studies showing that the rate of ocean warming has accelerated after 1991.

'Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought'.

Warmer ocean water also raises sea levels by melting ice, including around the edges of Antarctica and Greenland.

New research shows that ocean warming is accelerating more than we thought, and if left untreated, could further destroy marine life in the next few years.

For the new study, scientists used data collected by a high-tech ocean observing system called Argo, an global network of more than 3,000 robotic floats that continuously measure the temperature and salinityof the water.

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. This Trend has far-reaching consequences for fish or other organisms in the already oxygen-poor marine regions, for example, because in particular large fish in oxygen are not able to survive poor areas. Dubbed Argo, the AI fleet has provided consistent ocean warming data since the mid-2000s, and enabled the team to correct previous ocean warming observations. "The global warming signal is a lot easier to detect if it is changing in the oceans than on the surface".

'For example, even if we meet the target of Paris Agreement (to limit climate change), ocean will continue warming and sea level will continue rise. This means that "the ocean is saving us from massive warming right now", Malin L. Pinksy of Rutgers University told the New York Times.

Another study report from the European Union's Copernicus Climate Change Service had revealed that 2018 was the fourth warmest year, in terms of global surface temperatures, in records dating back to the 19th century. It has also contributed to increases in rainfall intensity and stronger, longer-lasting storms, such as Harvey in 2017 and Florence in 2018.
