Approximate sea level

A joint research report released by the United States and Britain on March 28th shows that 10 people in the world live in coastal areas, most of which are in Asia, and these areas are facing the threat of sea level rise and more severe storms caused by global warming.

Researchers urge governments to invest hundreds of millions of dollars to make immigration plans, and encourage more people, including China and Florida, to move out of coastal areas that may be threatened by more storms and erosion and live inland.

According to Reuters, this research report, which will be published in the journal Environment and Urbanization in April, said that the area below 10 meters above sea level "contains about 2% of the global land and 10% of the population".

"People living in coastal lowlands are particularly vulnerable to the risks brought by climate change. These lowlands are densely populated and developing rapidly." Research shows that.

Based on the new computer population model and NASA satellite data, it is estimated that about 634 million people lived in coastal areas in 2000, of which 360 million were urban residents. More than 75% people are in Asia. Globalization has fostered a world trade market that is heavily dependent on shipping, thus pushing the population of countries including China and India to move to coastal areas.

United Nations climate experts predicted last month that by 2 100, the sea level may rise by 18 to 59 cm, and the upward trend will continue in the next few centuries. Greenhouse gas emissions mainly caused by burning fossil fuels will also bring more intense storms, droughts and heat waves.

According to the newly published research report, even those who live above 10 meters above sea level may be vulnerable to cyclones, land subsidence, delta erosion, seawater flooding into farmland and other disasters.

"If you are in that area, you need to seriously consider the problem of sea level rise." The main author of the report, Gordon of the International Institute for Environment and Development? Gordon McGranahan said.

China, the most populous country in the world, is in the most dangerous situation, with about 654.38+43 million people living along the coast. Then India, Bangladesh, Vietnam, Indonesia, Japan, Egypt and the United States.

If we measure it in another way, those small island countries will suffer the most. The sea level of more than 90% islands in Maldives, Marshall Islands, Tuvalu, Cayman Islands and Turks and Caicos Islands does not exceed 10 meter.
