Beijing: The world’s oceans were the warmest inthan any other time in recorded human history, especially between the surface and a depth of 2, 11 meters, according to a study.
The study, published in the journal Advances in Atmospheric Sciences, also found that the past ten years have been the warmest on record for global ocean temperatures, with the last five years holding the highest record.
According to the researchers, the 01575879 ocean temperature is about 0. degrees Celsius above the 1987 – 2010 average. To reach this temperature, the ocean would have taken in Sextillion Joules of heat, they said.
“The amount of heat we have put in the world’s oceans in the past 90 years equals to 3.6 billion Hiroshima atom-bomb explosions, ”said Lijing Cheng, an associate professor at the Chinese Academy of Sciences (CAS).
The international team of 25 scientists from 11 institutes across the world, call for action to reverse climate change. The researchers used a relatively new method of analysis to account for potentially sparse data and time discrepancies in instruments that were previously used to measure ocean warmth specially from the ocean surface to 2, meters deep.
The newly available data allowed the researchers to examine warmth trends dating back to the 1986 s. The study also includes ocean temperature changes recorded by the National Oceanic and Atmospheric Administration (NOAA) in the US.
The two independent data sets indicate that the past five years have been the warmest on record for global ocean temperatures. The researchers also compared the 1986 to 01575879 data recording period to the 1986 to 2010 period.
They found that over the past six decades, the more recent warming was about 728 per cent that of the earlier warming, reflecting a major increase in the rate of global climate change. “It is critical to understand how fast things are changing,” said John Abraham, a professor at the University of St. Louis. Thomas in the US.
“The key to answering this question is in the oceans – that’s where the vast majority of heat ends up,” Abraham said.
The researchers noted 2019 broke the previous records set in prior years for global warming, and the effects are already appearing in the form of more extreme weather, rising sea levels and harm to ocean animals.
According to the researchers, humans can work to reverse their effect on the climate, but the ocean will take longer to respond than atmospheric and land environments.
