Climate change under worst-case scenarios can lead to the extinction of the world's population. This was reported by scientists from the United States, Germany and China in an article for the publication of the American Academy of Sciences (PNAS).
The authors of the publication believe that humanity pays little attention to the “worst-case scenarios” climate change. This problem can reach catastrophic proportions, scientists are sure.
The article says that over the past 30 years, an increase in greenhouse gas emissions has been recorded in the world. Not the most negative forecasts suggest that by the end of the century the average temperature on Earth may increase by 2.1-3.9 degrees. However, by 2070, areas with extreme heat, where the average annual temperature exceeds 29 degrees, can expand so much that they will contain two billion people.
According to researchers, the climate crisis could cause a “cascade of risks”, which will cause a consistent increase in problems of a different nature. For example, heat and degradation of territories can cause unrest in society.
“There is enough evidence that climate change can be catastrophic. We could enter such “endgames” even with modest levels of warming,” — the scientists concluded.
Earlier, Alexei Turkeev, a researcher at the Laboratory for Climate Change and the Environment, said that polar explorers had recorded an anomalous Australian heat wave in Antarctica.
