We often write about climate change and howit affects the oceans of the earth. Thus, according to the latest report of the International Panel of Experts on Climate Change (IPCC) under the auspices of the United Nations, which is devoted to current problems of the oceans, sea level rises due to melting glaciers, which entails potentially catastrophic consequences. Even more exciting are the numbers from the data analysis for 1950–2019. In the course of the analysis, an international group of scientists determined that the average temperature of the World Ocean in 2019 was 0.075 ° C higher than the average in 1981–2010. Such warming may seem insignificant, but given the huge volume of the oceans, an increase, even so small, requires a staggering influx of heat.
In a work published in Advances magazinein Atmospheric Sciences, researchers indicate that over the past 25 years, the influx of heat in the oceans equals 228 sextillion Joules. This is a very complex figure and it is rather difficult to imagine what exactly it means for the oceans of the Earth. For this reason, one of the co-authors of the study made a mathematical problem, so that you can compare 228 sextillion joules with the amount of energy released by the atomic bomb that the U.S. military dropped on Hiroshima during World War II in 1945.
According to scientists in an official press releaseresearch, the atomic bomb explosion energy in Japan amounted to approximately 63 billion Joules. And the amount of heat that the oceans have received since 1995, respectively, is 3.6 billion atomic bomb explosions in Hiroshima. Thus, on average, every second over the past 25 years, energy has been released into the ocean, almost equal to five atomic bombs. But what is even more disturbing is the increase in this temperature.

2019 is the hottest year in the history of observations
2019 broke several temperaturehighscores. So, July was the hottest month in the history of observations, and Europeans underwent extreme heat waves. All these changes are caused by human activities - the extraction of resources, the mass production of goods and food, deforestation and environmental pollution. If we consider the whole picture, then what is happening with the oceans, unfortunately, is a logical pattern. Glacier melting due to rising global ocean temperatures is faster, causing sea levels to rise. Dolphins and other inhabitants of the deep sea die because the changes are too rapid and they simply do not have time to adapt to them.

Moreover, even an increase in the amount of water,which evaporates into the atmosphere due to heat, negatively affects our planet. All these changes make hurricanes and typhoons stronger; extreme weather conditions are gradually becoming the norm for us. So, terrifying fires in Brazil, Siberia and Australia, along with heavy rains and frequent floods, are gradually becoming the new norm. The authors of the study again recall that if urgent measures to combat climate change are not taken, the situation on the planet will only worsen.
