According to a study assessing the tragedy of a fictional nuclear war between two countries, its worst effect will be on the oceans, which will increase the amount of acid in the oceans and affect many other sea creatures, including corals and oysters. In this study, published in the journal Geophysical Research Letters, researchers explored the effects of nuclear war on climate change in the oceans.
Professor Alan Robock of the Rutgers University of America said, “The nuclear war will change the chemistry of the ocean. The world’s weather cycle will be severely affected, and increasing the amount of carbon in the oceans can increase the number of acidifications. For this study, researchers have used the Global Climate Model, which shows how the explosion of nuclear weapons increases the amount of black carbon in the upper atmosphere.
Researchers have considered a number of hypothetical nuclear wars for this study, including a small war between India and Pakistan and a relatively larger war between the US and Russia.
Researchers report that burning fossil fuels can cause excess carbon dioxide to enter the ocean and react with water to form carbonic acid, making the ocean more acidic and lowering carbonate ions. The National Oceanic and Atmospheric Administration have stated that many other marine organisms, such as corals, oysters, make shells with the help of carbonate ions, and their skeletons remain the same.
Researchers said that highly acidic oceans make it difficult for marine organisms to build and maintain their shells and skeletons. He said that because of the nuclear war, the vast amount of mist in the atmosphere prevents the sun’s rays from reaching the Earth. This causes the global cold outbreak to increase, which means that the pH level on the sea surface will also increase over the next five years after the eruption and a slight drop in acid levels can be recorded.
Researchers said that increasing the coolant could cause carbonate ion levels to decline for about 10 years, and marine organisms would face many challenges in their maintenance. Robock said, ‘It is well known that climate change due to nuclear war has the greatest impact on agricultural land. But it is also true that it has a serious impact on the marine ecosystem as well. In such a situation, it will be difficult for the survivors to get food from the sea after the war.
