Pariahan village pumps drinking water from a well on Nov. 28 2018 in Bulacan north of Manila in the Philippines

A new scientific analysis has discovered that climate change implications are more disastrous than once thought.

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

The subtitle gives the answer: "Observational records of ocean heat content show that ocean warming is accelerating".

A resident of Pariahan village pumps drinking water from a well, on November 28, 2018 in Bulacan, north of Manila in the Philippines. This effect alone would lead to a swelling of the sea level of up to 30 centimeters. And warming oceans lead to a lot of other dire consequences, some immediately felt by humans and other creatures, and some more generally destructive to life as we've long known it.

About 93 percent of excess heat - trapped around the Earth by greenhouse gases that come from the burning of fossil fuels - accumulates in the world's oceans.

The seas are warming much faster than previously feared, warns new research.




Mr Hausfather said: "While 2018 will be the fourth warmest year on record on the surface, it will most certainly be the warmest year on record in the oceans, as was 2017 and 2016 before that".

That network has provided consistent data on ocean temperatures and other metrics since the mid-2000s. According to Lijing Cheng, one of the study's authors, temperatures down to 2,000 meters rose about 0.1 degree Celsius (0.18F) between 1971-2010, according to Reuters.

'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.

In the Arctic, the warming oceans are also causing a serious decline in sea ice, which only compounds the ongoing threats of climate change such as sea level rise.

'If you want to see where global warming is happening, look in our oceans, ' said Zeke Hausfather, a graduate student in the Energy and Resources Group at the University of California, Berkeley, and co-author of the paper. According to a report published Thursday in the journal Science by authors in the United States and China, this set a new temperature record in 2018. If no actions are taken ("business as usual"), the upper ocean above 2000 meters will warm by 2020 ZetaJoules by 2081-2100, which is about 6 times larger than the total ocean warming during the past 60 years.

Ocean temperatures are less influenced by year-to-year variations in the weather. Moreover, the revised and updated ocean heat content record is much more in step with the warming predicted by climate models, thereby providing much more confidence in expectations for the future. Warm oceans will also increase the moisture in the atmosphere which will induce powerful storms like Hurricane Florence and Hurricane Harvey.
