The average temperature of the world’s oceans is warming at an increasing speed, reaching the highest temperature ever recorded. Scientists are anxious with a new study on Monday that revealed the moderate temperature of the ocean’s in 2019 used to be 0.075 degrees Celsius (0.135 degrees Fahrenheit) higher than 1981-2010 moderate.
An international team of 14 scientists researched analyzing data going back to the 1950s, observing at temperatures from the ocean surface to 2,000 meters deep. The study was published in the journal Advances in Atmospheric Sciences. It is proved that more than 90% of the heat produced by humanity’s greenhouse gas emissions, gets absorbed by the seas.
To make it easier for us to understand, one of the scientists calculated it by putting it into an explosive frame of reference. He compared the amount of energy released by the atomic bomb to the US military dropped on Hiroshima, Japan, in 1945. Study author John Abraham, from the University of St. Thomas in Minnesota, described the heat to be equivalent to five Hiroshima atomic bombs being dropped into the water every second. But, over the passing time, the heating has accelerated as carbon emissions have risen, which is now equivalent to three to six atomic bombs per second.
Lijing Cheng from the Chinese Academy of Sciences said in a press release, "The Hiroshima atom-bomb exploded with an energy of about 63,000,000,000,000 Joules,"
"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," he added.
Ocean has always been a good indicator of the real impact of climate change. The increasing temperatures of the ocean affecting marine species and ecosystems. The high temperature is also leading to cause coral bleaching and the loss of breeding grounds for marine fishes and mammals by decreasing the oxygen level, making it more acidic. Humans' benefits from the ocean are also in danger as it is threatening food security, increasing diseases, and causing loss of coastal protection due to extreme weather circumstances.
On the other side, the sea level is rising because of the added water from melting ice sheets and glaciers due to global warming. It can lead to the most dangerous long-term impacts of climate change. It threatens billions of people living in coastal cities. Scientists are emphasizing on reducing carbon emissions that would help limit warming. So we have to take essential and effective steps without making any further delay.
