The worldwide team analyzed a number of new studies assessing ocean temperatures to conclude that ocean warming is "stronger" than predicted by previous research.

The planet is "clearly warming", according to the analysis.

A study conducted by researchers from China and the United States has found that oceans are warming rapidly than previously estimated and this trend could drastically affect marine life.

The Science report linked the warming to more rain, increased sea levels, coral reef destruction, declining ocean oxygen levels and declines in ice sheets, glaciers and ice caps in polar environments.

"The global warming signal is a lot easier to detect if it is changing in the oceans than on the surface".

'It´s mainly driven by the accumulation of greenhouse gases such as carbon dioxide in the atmosphere due to human activities, ' said Lijing Cheng, a lead author of the study from the Chinese Academy of Sciences. As a effect, ocean warming has also accelerated faster than scientists expected.

Scientists warn these temperatures are driving sea levels and helping to fuel more intense hurricanes and other extreme weather. 2018 is likely to be the hottest year for the oceans on record, beating out 2017 which held the record. Ocean temperatures are reportedly not affected by functions that occur annually like El Nino. This ocean-monitoring battalion, called Argo, has provided consistent and widespread data on ocean heat content since the mid-2000s. According to the Coupled Model Intercomparison Project 5 (CMIP5) models, the temperature of the top 2,000 meters of global oceans will increase by 0.78 degrees Celsius by 2099. "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.

'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.

The new study analyzed earlier published information and data compiled by Argo, an worldwide system of almost 4,000 floats that measures temperature and saline levels in the upper parts of the world's oceans. US President Donald Trump, who wants to promote US fossil fuels, plans to pull out of the pact in 2020.

The prediction is over four times more than estimates from the UN Intergovernmental Panel on Climate Change suggesting the oceans were taking up around 8 Zetajoules of energy each year - an "8" followed by a whopping 21 zeros. Warmer seas release more moisture that can stoke more powerful storms.

He told Reuters that records for ocean warming had been broken nearly yearly since 2000.
