Immigrants from Linhai to Ningbo

First of all, we must understand the reasons for sea level rise: sea level rise is a global sea level rise phenomenon caused by global warming, melting of polar glaciers and thermal expansion of upper seawater. Research shows that the global sea level rose by 10 ~ 20cm in the last century, and it will accelerate in the future. However, the actual sea level change in a certain area of the world is also affected by local vertical land movement-slow crustal rise and fall and local land subsidence. The sum of global sea level rise and local land rise and fall is the relative sea level change in this region.

There are many factors leading to sea level rise: ocean thermal expansion, mountain glaciers, Greenland land ice and Antarctic ice sheet melting. In the past hundred years, most mountain glaciers in the world have been shrinking. For example, although the Qinghai-Tibet Plateau may not have a unified boundless ice sheet during the ice age like the Antarctic continent today, one thing is certain, that is, the mountain glaciers that once existed in large numbers here gradually melted and disappeared in the long years.

Glacier melting caused by global warming is the main reason for sea level rise, but according to a study conducted by the National Center for Atmospheric Research in July 12, assuming that global greenhouse gas emissions are stable and global temperature does not rise, sea level will still rise for hundreds of years.

In addition to migration, it can be solved by the following methods:

1. Build protection works in coastal areas to prevent seawater intrusion, such as sea walls.

2. Reasonably guide immigrants to move inland and reduce coastal ecological pressure.

3. Save energy and reduce emissions, reduce energy consumption and reduce carbon dioxide emissions.

4. Develop new energy sources, rationally adjust the energy structure, and solve the refugee problem caused by sea level rise in the long run.

5. Plant trees and grass to reduce the content of carbon dioxide in the air.

6. Vigorously develop a low-carbon environment-friendly economy to achieve sustainable economic development.
