After analyzing the data from 1950 to 2019, an international team of scientists determined that the average ocean temperature in the world in 2019 was 0.075 degrees Celsius. A higher than average figure between 1981 and 2010.
“0.075 degrees Celsius” may seem like an insignificant amount. However, given the enormous volume of the oceans, an increase, albeit small, would require an incredible flow of heat: to be precise, 228 sextillions of Joules (a number followed by 21 zeros), according to the study published in Advances magazine in Atmospheric Sciences.
Given the difficulty of imagining such a number, one of the scientists behind the study found another method to explain it: comparing it with the amount of energy released by the atomic bomb that the United States Army launched on Hiroshima in 1945. ” The bomb Hiroshima atomic bomb exploded with an energy of about 63 million Joules, “says Lijing Cheng of the Chinese Academy of Sciences. ” The amount of heat we have released into the world’s oceans over the past 25 years is equal to 3.6 billion Hiroshima atomic bomb explosions. “
An average of four atomic bombs that have exploded in the ocean every second for the past 25 years. Furthermore, there is an even more worrying fact: the rate is not stable, but is increasing. In 2019, warming the oceans amounted to “about five Hiroshima bombs, every second, day and night, 365 days a year,” says study author John Abraham, of the University of St. Thomas in Minnesota.
This energy is having a huge impact on the environment. The ice is melting faster, causing the sea level to rise. Many marine species are dying because they are unable to adapt quickly enough to temperature and the increase in the amount of water that evaporates into the atmosphere due to heat also has a negative impact on our planet. ” It makes hurricanes and typhoons more powerful and makes the rains more intense, ” concludes Abraham.
