If the North and South Pole melt and the sea level rises by 66 meters, which city in China will disappear?

In the final analysis, global warming is still the wanton destruction of human beings. Humans burn coal, oil, natural gas and trees, producing a large amount of carbon dioxide and methane and entering the atmosphere to heat up the earth, unbalance the carbon cycle, and change the energy conversion form of the earth's biosphere. Since the Industrial Revolution, carbon dioxide levels in the atmosphere have increased by 25%, far more than the entire historical record of the past 160,000 years that scientists have possibly mapped, and there are no signs of slowing down. The increase in carbon dioxide emissions in the atmosphere is the root cause of global warming.

Since the natural geographical environment is an organic whole, global warming not only changes the global climate, but also brings changes to the global hydrology, biology, etc. One of the results of global warming is the rise of the global sea level, here There are two main reasons. On the one hand, global warming will lead to an increase in the average temperature of global seawater, especially the surface seawater, which will lead to the expansion of seawater volume and promote sea level rise. On the other hand, global warming will accelerate the melting of glaciers in two-tier regions and high mountains. The earth's glaciers are the main means of existence of the earth's freshwater resources. We cannot underestimate the consequences of global glaciers' melting.

Now that sea levels are rising due to global warming is a certainty, people living on coasts and islands are probably the group that knows it the most. According to satellite data, in 2014, compared with 1993, the sea level rose by 2.6 inches, or about 6 centimeters. According to a 2013 report by National Geographic, there are more than 5 million square miles of ice on the earth. If all this ice melted, the sea level would rise by 216 feet, which is almost 66 meters.

Since the eastern part of China is a coastal area, it will definitely suffer. If the sea level rises by 66 meters, which cities in China will disappear? Expert reminder: It is time for human beings to wake up. If the sea level rises by 66 meters, Shanghai will be the first to suffer among the coastal cities in China. We can see from the map that after the sea level rises by 66 meters, almost all the coastal cities in eastern China will become vast oceans. Submerged, even some central provinces such as Jiangxi and Hunan are threatened.

To give an example, the average altitude of Xiamen City is 63 meters, which seems to be fine, but it is not. There are many mountains in Xiamen, which belong to the terrain with a large height difference. Many areas in Xiamen are less than 10 meters above sea level. Another example is Nanning, the average altitude. It is 72 meters. In fact, when the sea level rises to 66 meters, most cities in Nanning will be submerged, and Shijiazhuang, Dalian, Fuzhou and other cities are also needed. Therefore, if the sea level rises by 66 meters, China's coastal areas and economically developed areas will basically be be submerged.

However, some experts believe that the sea level rise of 66 meters is only a panic for people at present, but it is just that humans should be alerted, because the current sea level rise of 66 meters is just an erection, and the premise of this erection is global warming. , Although global warming is a major trend at present, the erection of this diagram is a straight line thinking. It only reminds us to be prepared for danger in times of peace, but it cannot be denied that in the future development, it is impossible for the sea level to rise by 66 meters. Therefore, experts still remind everyone that human beings should be aware of environmental protection now, because once the world warms, we humans will be hurt in the end.
