A new study by scientists found that rising temperatures due to climate change will cause 2 to 3.5 billion people to be exposed to uninhabitable temperatures after 50 years.
Scientists continue to work to reveal the critical consequences of climate change that will deeply affect the future of Earth and humanity. A new study by ecology scientists to understand the consequences of climate change shows that rising temperatures will be exposed to temperatures that billions of people will have difficulty living in 50 years from now.
Ecology expert Marten Scheffer from Wageningen University in the Netherlands explained that an annual temperature increase of 1.8 degrees was observed due to climate change, and billions of people would not be able to live without cooling technologies if this temperature increase continues.
If the annual temperature increase continues in this way, it can be seen that the change in the number of people who will be affected by the rising temperatures will be directly related to how much heat-shielding carbon dioxide emission will increase or decrease.
3.5 billion people will face extreme temperatures after 50 years
The new climate change study published by scientists in the journal Proceedings of the National Academy of Sciences on Monday predicts that approximately 3.5 billion people will live in extremely hot regions by 2070.
The study shows that 50 years later, although before 2070, several billion people can only live in extremely hot places thanks to cooling technologies.
Researchers of the study, published in the Proceedings of the National Academy of Sciences, studied human communities as well as bears, birds and bees to find the “climate niche” where civilization flourished. The researchers looked back 6,000 years to find the best temperature for people to live. In the examination, it turned out that the average annual temperature suitable for people to live is between 11 and 15 degrees.
The number of people living in regions that are much warmer than the average temperature that people can live is increasing
Scientists have examined places that are expected to be uncomfortably warmer than this temperature value after detecting the appropriate average temperature. As a result of the analysis, it was determined that at least 2 billion people could live in the regions expected to be much warmer than the appropriate average temperature in 2070.
Currently, about 20 million people continue to live in places warmer than 29 degrees annually. These regions, which are located in a certain region of Saudi Arabia and near the Sahara Desert, make up 1 percent of the earth.
Currently, a very small region faces extreme temperatures, but as the world gets crowded, large parts of Africa, Asia, South America and Australia may also face similar temperatures.
Chi Xu from Nanjing University in China, one of the researchers of the study, said that measures to be taken for climate change over the next 50 years will affect the lives of 1 billion to 3.5 billion people.
One of the co-authors of the study, climate expert Tim Lenton from Exeter University in Britain, said that by the end of the century we live in, the population in the poor regions is expected to triple. Lenton added that this population growth in the poor regions will face quite difficult conditions to deal with unbearable temperatures.
