Hundreds of years of famine and the devastation of the oceans. Scientists have modeled the effects of a nuclear war
Despite the statements of current US and Russia presidents on the willingness to continue nuclear weapons reduction, the war in Ukraine has again caused concern about nuclear conflict. In a new study, scientists at the University of Tasmania modeled the life of the planet in the case of nuclear winter. In focus. Technology has appeared its Telegram channel.

Tyler Ror's biogeochemist used a mathematical model to model climate and life in the ocean and on land. Unfortunately, the forecasts are disappointing. In his work, Dr. ROR was based on the research of Karl Sagan. The model of scientists provides a nuclear war scenario between the States and Russia, which results in about 150 billion tons of soot from cities. The wards will reach the upper atmosphere.
Scientists warn that their model involves sharp climatic changes that will affect not only sushi but also the oceans. Thus, according to scientists, the territory of the Arctic sea ice will increase by 50%, blocking the coastal areas used for fishing, as well as large ports and trade routes throughout Europe. For example, it is known that sea ice blocks such large seaports as Copenhagen in Denmark and St. Petersburg in Russia.
The study also shows that even in the case of a limited nuclear conflict between India and Pakistan, it will be terrible from 27 to 47 billion tons of soot. The model assumes that even in this case, the amount of Arctic sea ice will increase so much that it will be able to block the most important ports throughout Northern Europe. However, the effects of nuclear winter will not only affect life on land and climate, they will also affect life in the ocean.
According to the study, the fall in the light of the ocean and its average temperature will lead to the death of seaweed, which is an important link in the food chain of underwater life. Scientists warn that nuclear winter will affect the entire oceans, but the worst consequences are highly latitude, including the whole of Europe, and especially the Baltic countries - here researchers are already fixing the lack of oceanic light.
It should be noted that fishing is now only a small share of the European economy. However, researchers suggest that the destruction of land agricultural systems will make Europeans decide the food crisis through food production in the sea, which, unfortunately, will not be easy. According to Dr. Roor, they with their colleagues suggested that the modeling of nuclear winter and its consequences would show an increase in Arctic ice and reduce the amount of algae.
However, they could not imagine how long the consequences of the nuclear war would persist. The study showed that the consequences of the destructive nuclear winter remained unchanged decades after its completion. In addition, scientists suggest that the oceans will recover for hundreds of years - the model has shown that even a return to the usual temperature and light will not return marine life to its pre -war existence.
It is assumed that the sea ice will go into a new expanded state and will be stored in this form for hundreds of years. The study also found that the global productivity of the marine environment will return to its habitual condition within 10 years after the end of nuclear conflict, and possibly even exceeding it. But, unfortunately, you do not have to rejoice. Researchers note that the main problem of ocean recovery is that the water is too slowly heated and cooled.
