Ocean warming is equivalent to dropping five nuclear bombs every second! In 20 19, the ocean temperature reached a record high.

Scientists say that the current global ocean warming rate is equivalent to the warming rate caused by the heat generated by dropping five Hiroshima atomic bombs into the ocean every second. A new study released on Monday showed that 20 19 was another record year of ocean warming, and the sea water temperature reached the highest temperature on record.

Cheng Lijing, an associate professor at the Center for International Climate and Environmental Science of China Academy of Sciences, is the first author of this study. He made a calculation that the energy of Hiroshima atomic bomb explosion is about 630 billion joules, and the heat that human beings have brought to the world's oceans in the past 25 years is equivalent to 3.6 billion Hiroshima atomic bombs.

In other words, this is equivalent to dropping about four Hiroshima atomic bombs into the ocean every second in the past quarter century. However, because the speed of climate warming is still accelerating, we are dropping these imaginary nuclear bombs faster than ever before.

John abraham, one of the authors of this study and a professor of mechanical engineering at St. Thomas University in Minnesota, is even more outspoken. He said that our ocean is now equivalent to exploding five or six atomic bombs every second.

An international team of 14 scientists from China and the United States studied the data since the 1950s. They observed and measured the temperature from the ocean surface to the depth of 2000m. The study, published in the journal Progress of Atmospheric Science, also shows that the ocean is warming faster and faster.

Although the past decade has been the highest global ocean temperature on record, the five hottest years on record have all occurred in the past five years. Kevin Trenberth, a well-known senior scientist in the Climate Analysis Department of the National Center for Atmospheric Research, said: The rising trend of temperature is relentless, so we can safely say that most of the warming is man-made climate change.

The research shows that although the ocean has been warming continuously from 1955 to 1986, the warming speed has accelerated in the past decades. From 1987 to 20 19, the extent of ocean warming is 450% larger than that in the previous period.

Professor Cheng Lijing said that the ocean temperature in 20 19 years was 0.075 degrees Celsius higher than the average temperature between 198 1 and 20 10 years. At present, the calculated ocean warming is irrefutable and is further evidence of global warming. There is no reasonable substitute to explain this warming except the heat dissipation gas released by human beings. He added that in order to achieve this warming, the ocean will absorb 22.8 billion megajoules of heat.

The ocean is an excellent indicator of the impact of climate change. They cover almost three-quarters of the earth's surface and absorb most of the world's heat.

Professor Cheng Lijing further explained that even if a small amount of heat affects the atmosphere and land, the resulting global warming will lead to an increase in catastrophic fires in Amazon, California and Australia in 20 19, and we think this situation will continue until 2020. Global warming has caused ocean heat waves in tasman sea and other regions. When he said this, we knew that the wildfire in Australia was still burning.

Ocean warming has also caused a large number of deaths from plankton to whales, and has caused hundreds of millions of cod deaths; And led to the emergence of various abnormal weather, such as Hurricane Harvey caused by 20 17 Gulf of Mexico hotspot, and now the global rainstorm and flood are more frequent.

Mankind is facing a catastrophic impact. This is not the first time that scientists have called for immediate measures to deal with climate change!
