About 1 billion people in the world now live in areas lying no more than 10 m above sea level, of which about a quarter are no more than 1 m. In the next few decades, many may have to leave their homes, the authors warn research published in the journal Nature.

Scientists write that even if immediate measures are taken to reduce the emission of greenhouse gases, the level of the World Ocean will rise by about 50 cm by the end of the 21st century (in the 20th century - by 11-16 cm). In the worst case, it can climb 2 m, which will lead to flooding of vast territories where hundreds of millions of people live.

According to scientists, by the 2050 year, the areas where approximately 300 million people live will be below the average annual coastal flood. This means that they will be threatened by severe flooding at least once a year. According to the same forecast, by 2100, the territories where 200 million people live may be below sea level, which will make these lands unsuitable for living.

“The data shows that there are far more people living in vulnerable areas than we thought,” said Benjamin Strauss, one of the authors of the study and head of the Climate Central organization. According to him, the authorities must immediately take measures to prevent the "economic and humanitarian catastrophe."

The greatest threat, according to scientists, hangs over the densely populated coastal areas of eight Asian countries - China, Bangladesh, India, Vietnam, Indonesia, Thailand, the Philippines and Japan, where about 150 million people live, or about 70% of all potential migrants. However, serious problems, as follows from the assessment of Climate Central, will have to face other states. In 19 countries of the world, in particular in Great Britain, Brazil, Egypt, Nigeria, etc., by 2100 year, areas where 1 million people live can be flooded and unsuitable for living.

Small island states, according to the forecast of scientists, are completely at risk of death. According to experts, three-quarters of the Marshall Islands, and a third of the population in the Maldives, live in places that could hide under water in the next 80 years.

“And long before these lands are flooded, residents will face salinization of fresh water sources and frequent floods. In small island states, land can become uninhabited long before flooding, ”experts warn.

The study also notes that rising sea levels will threaten the lives of several hundred million people, despite the fact that their places of residence will remain uncrowded. According to experts, the threat of annual flooding due to coastal floods will hang over the areas where now lives from 360 million to 640 million people.
