Climate change affects 10% of the world population

According to a study published July 1 in the journal of the National Academy of Sciences, if the state of greenhouse gas emissions does not decline, by the end of the century, every 10 people in the world One gender has to live in an area where crops, water, ecosystems and health are severely affected by climate change.

>>>Frequency of floods will increase due to climate change

The results of the study show that the southern Amazon basin will be most affected by climate change, directly affecting crops, ecosystems and water resources. Next is Southern Europe, with changes in water resources and ecosystems. In addition, tropical regions such as Central America, Africa and the northern region of South Asia also suffered from this change, affecting agricultural production and people's lives.

The main author of the study, Franziska Piontek - of the Institute for Influence Research of Climate Potsdam (Germany), said the overlapping effect of climate change on different areas of life is possible. energy will interact with each other and increase pressure on human life in areas affected by climate change.

After examining the effects of climate change on different levels of water, agriculture, ecological systems and human health, the research team found that the effects overlap greatly. The area of ​​climate change begins to increase when the global temperature increases by 3 degrees Celsius compared to the average temperature of the period 1980 - 2010. If the global average temperature increases by 4 degrees Celsius, 11% of the population Global numbers will be severely affected in at least two areas, but there is no overlap in all four areas of crops, water resources, ecosystems and health.

This is the first study to identify hot spots due to the effects of climate change through these four areas, based on a comprehensive computer system that simulates climate change and its effects.
