Science claims that there will be at least 187 million people lost their place at the end of the century

The reason everyone guessed it was: climate change again.

Ice at the two poles are melting fast is one of the serious consequences of climate change, but it is also what science has grasped for many years. The thing, the science doesn't know how fast the melting of ice can be.

In Greenland - the world's largest ice island in the North, ice is melting at a rate six times faster than four decades ago. Estimated every year, 286 billion tons of ice has disappeared from the island. And Antarctica in the 1980s, the amount of ice lost was 40 billion tons / year. Yet, according to data in the last decade, the number jumped to 252 billion tons.

The ice in Greenland is melting very fast

That's what the latest report is published in the Proceedings of the National Academy of Sciences (USA). Experts confirm that the melting speed is increasing very fast, and almost certainly will have serious consequences for mankind.

Accordingly, in the next 80 years, if the Earth temperature increases by 5 ° C, the sea level will increase by nearly 2m. With such an increase, there will be at least 187 million people who lost their place to live, including people in two major cities, New York and Shanghai.

The melting speed is being underestimated

Greenland has a permafrost of 1.7 million square kilometers, three times larger than the state of Texas in the United States. According to data from the National Snow and Ice Center (US), together with the Antarctic ice shelf, both contain 99% of the world's freshwater in the form of ice and snow, the same thickness up to kilometers.

But human activities pushed a huge amount of greenhouse gases into the atmosphere, forcing oceans to absorb 93% of the increased heat. Ice shelves begin to melt at dizzying speeds.

It is estimated that sea level will increase by about 97cm by the end of the 21st century.

In 2013, experts at the UN predicted that the sea level would rise by about 97cm by the end of the 21st century. But according to the new report, it was recorded based on what was happening, the number had to be twice as high.

The risk of this situation is only 5%, but experts believe that is a number worth worrying about, because everything can happen.

187 million people become victims of melting ice

Sea level increases by 2m, meaning that the Earth loses 1.8 million km 2 of land. That is the number larger than the area of ​​France, Germany, and Spain and the whole of Britain combined.

Coastal cities such as London, New York and Shanghai will suffer severe consequences. Small island states in the Pacific - such as Vanuatu, for example - will also completely disappear, or become uninhabitable. The lands responsible for food production for the entire world - like the Nile Delta, are not intact.

This scene will not be strange at the end of the 21st century?

In total, there will be about 2.5% of the world's population losing their home, equivalent to 187 million people.

"To make it easier to imagine, we have seen a wave of refugees in Europe from Syria amounting to a million. Multiply by about 200 times there will be a number of people who will lose their homes if the sea level rises," said Jonathan Bamber. research author.
