30% of the world's population may have to migrate because of climate change

Climate change has caused temperatures in some regions of Russia such as Krasnodar to reach over 40 degrees Celsius in the summer, making the place unsuitable for some elderly people.

On July 2, Russian climatologist Alexei Kokorin said that in the worst case scenario, climate change could kill nearly 3 billion people - equivalent to about 30% of the world's population - by the end of this century. In the best case scenario, he said the figure would be 10%.

Kokorin believes that efforts by countries to achieve carbon neutrality will help avoid the worst-case scenario. However, even if all goes well, some of the world's population will be forced to migrate due to lack of clean water.

Mr Kokorin also said that Russian pensioners are starting to take climate change into account when choosing where to live. He pointed out that people from Chukotka used to try to move to the Krasnodar region when they retired. However, in recent years they have moved to Omsk and Novosibirsk oblasts, because Krasnodar is now too hot for them. This suggests that people have adapted their residences because of the climate.

Summer temperatures in Krasnodar can rise above 40°C, which is harmful for older people who have lived in the north for many years, according to Mr. Kokorin.

Carbon neutrality is one of the conditions for implementing the Paris Agreement on Climate Change (COP). Currently, the US and members of the European Union (EU) plan to achieve carbon neutrality by 2050. This timeline for Russia and China is 2060, and for India it is 2070.

Last June, the United Nations World Meteorological Organization predicted that global temperatures could reach record levels within five years, due to greenhouse gas emissions and a shift in ocean currents from La Nina to El Nino.
