THE world’s oceans were the warmest in 2019 than any other time in recorded human history, especially between the surface and a depth of 2,000 metres, 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 2019 ocean temperature is about 0.075 degrees Celsius above the 1981-2010 average. To reach this temperature, the ocean would have taken in 228 Sextillion Joules of heat, they said. “The amount of heat we have put in the world’s oceans in the past 25 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 14 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 2,000 metres deep.
