The extra heat absorbed by the ocean every year is more than eight times the world's annual energy consumption. Resplandy suggests her group's findings make that more hard.
Now, researchers have developed what they say is a highly precise method of detecting the temperature of the ocean by measuring the amount of oxygen and carbon dioxide in the air.
Accurately assessing the rate at which the oceans are warming is critical if we're to predict the effects on marine life and the climate.
The scientists say global policymakers have so far failed to make intact ecosystems an explicit target for conservation, such zones risk disappearing completely.More news: How To Rock An Oversized Shirt Like Deepika Padukone
The discovery took place because the authors of the new study were not satisfied with the information about the temperature and salinity of the ocean, which is compiled from a system of nearly 4,000 ocean buoys in waters around the world, called Argo.
"These estimates all use the same imperfect ocean dataset", they wrote.
Authors of the study said, "suggests that ocean warming is at the high end of previous estimates, with implications for policy-relevant measurements of the Earth response to climate change, such as climate sensitivity to greenhouse gases and the thermal component of sea-level rise". Also, the Argo floats do not track much of what happened before 2007. They gauged ocean heat by taking a gander at the consolidated measure of O2 and Carbon dioxide in air, an amount they call "atmospheric potential oxygen" or APO.
The team analyzed oxygen levels in the ocean and carbon dioxide (CO2) at three locations in the lower, middle and upper part of the Earth: the tip of Tasmania in Cape Grim, La Jolla, California, and Alert, Canada, only 800 kilometres from the north pole.
Besides, all that heat absorbed by the ocean will cause some unfortunate changes. In addition, they tracked 25 years of data, from 2016 to 1991.More news: Oprah door-knocks for Democratic candidate in Georgia
A host of countries, including the USA and China, signed the Paris Climate Accord in 2015, which aims to keep average global temperatures from rising more than 2 degrees Celsius above pre-industrial levels. So some climate "refugee" squid populations there are already swimming north in search of colder water with more oxygen.
Despite that, the researcher said that it is not a reason to lose hope, but that the findings should serve to duplicate efforts to save the planet.
However, researchers calculate that humanity could still avoid a warming of two degrees Celsius if the maximum carbon emission limit was further reduced by 25 per cent.
Oceans warming faster than we thought, "fish refugees" seeking cooler waters, wilderness areas that may vanish altogether - and even a warning that the traditionally moderate British weather is getting more extreme.More news: 'A real fight': UFC boss dares Mayweather to fight Khabib in MMA
