The plague has killed about one-third of Europe's population, and bacterium-causing bacteria have been frozen in the snow for thousands of years, but could spread again in the world due to global warming, global warming and climate change, according to recent warnings.
The professor of international history and director of the Oxford Center for Byzantine Studies Bert Frankopan warned that epidemics, such as the Black Plague, also called "black death", may return again, posing a new threat to the human race if the ice continues to melt.
Francopane's warning came as part of a UN report, noting that atmospheric temperatures are likely to rise by 1.5 degrees Celsius between 2030 and 2052 if global warming continues at its current pace. If the world fails to take rapid and unprecedented action to stop the increase, And humanity are coming to a great disaster.
According to the United Nations report on global climate change, the effects of climate change, ranging from drought to rising sea and ocean levels, will be less extreme than the effects of a two-degree rise in temperature, according to the British newspaper Mirror.
"There is absolutely no chance that countries will be able to keep the rise in global temperatures in the range of a degree and a half Celsius," he said.
"It is not the sinking of cities or countries, like the Maldives, but the freeing of bacteria and bacteria that have been frozen for thousands of years and their emergence and spread in the world," he said at the Cheltenham literary festival. "Such a thing under climate change would have a huge impact.
"In the 1850s, the Earth's temperature rose 1.5 degrees Celsius, probably because of the activity of solar radiation and volcanic activity, which changed the life cycle of Yersenia plague," he said, allowing these small bacteria to evolve into "black death" .
Black Death, Black Plague or Great Death was the deadliest epidemic in human history, killing between 75 million and 200 million people in Europe and Asia, culminating in the death of Europe between 1347 and 1351.
