A latest study has shown that the total amount of man-made heat energy consumed by the oceans worldwide has become twice since 1997. The Huffington Post wrote that since long, scientists were aware that nearly 90% of global warming-produced heat energy ends up in the world's oceans.

However a new study has provided latest data on how much heat the oceans have absorbed during the last 150 years. Scientists used data from belonging to a back as the 1870s, collected from British research ship Challenger, and utilized data from technologically advanced underwater monitors and computer models.

The study discovered that the world's oceans had absorbed nearly 150 zettajoules of energy from 1865 to 1997. In the time period from 1997 to 2015, the research detected that the oceans consumed the same amount during the 18-year period.

For putting the entire absorbed energy into perspective, if 1 atomic bomb was exploded in a second for a year, the total amount of energy the explosions’ released would just amount to 2 zettajoules. To reach the amount of heat energy the oceans absorbed from 1997 to 2015, an atomic bomb would be required to be exploded per second for 75 years.

While speaking to The Huffington Post, co-author Paul Durack, an oceanographer at the Lawrence Livermore National Lab in California, said that the alterations they talked about are actually big numbers, and are nonhuman numbers.

The researchers said that despite using computer simulations, which were used for data stimulation for decades in the absence of good data, the figures were still reliable. They discovered that most heat got trapped in the upper 2,300 feet of the oceans worldwide, though the deeper oceans have been absorbing more and more amounts of energy every year.

But the authors of the study are more worried about the speed with which the numbers have been increasing, rather than the raw numbers.
