A country that disappeared because its coastline rose.

200 1, 1 1, a report published by the Earth Policy Institute in Washington, USA, said that due to the sea level rise caused by the greenhouse effect, 1. 1.00 million nationals of Toulouse, a South Pacific island country, would be forced to emigrate to New Zealand, and Toulouse became the first country in the world to relocate all its population due to sea level rise. According to the research report of the International Panel on Climate Change, the sea level has risen by 20 to 30 centimeters so far. It is estimated that the islands of this country will be submerged by seawater within 50 years. Other Pacific low-lying island countries such as Kiribati, Cook Islands, Nauru and Western Samoa have also experienced similar situations. Nauru President Harris once said that there are so many low-lying island countries in the Pacific Ocean. If the world does not pay attention to sea level rise, it will be a real modern massacre. It can be asserted that "Turua will never be the last country forced to emigrate because of rising sea level".

Not only the island countries surrounded by the sea of Wang Yang are threatened by sea level rise and land occupation, but also the low-lying areas of some coastal mainland countries are threatened by sea level rise. According to the estimation of environmental experts, the maximum sea level rise in 2 1 century can reach 1 meter. According to a report published by the World Bank in 2000, if the sea level rises by 1 m, half of the cultivated land in Bangladesh will be swallowed up. It is conceivable that Bangladesh, a country with a population of 65.438+0.3 billion, is facing threats. Other Asian countries with irrigated farmland plains, such as China, India, Thailand, Viet Nam and Indonesia, are also facing the same problem. Even the United States, which refuses to sign an international convention to reduce carbon dioxide emissions, faces the same threat. According to the research of the Environmental Science Center of the University of Maryland, every time the sea level rises 1m, the coastline will shrink 1500m. Accordingly, in the next 50 years, the United States will gradually lose 36,000 square kilometers of land, including the States along the Atlantic coast, the Mississippi River and the Gulf of Mexico, and the low-lying areas on Capitol Hill in Manhattan and Washington, D.C. will also be difficult to survive. Recent scientific research shows that with the increase of greenhouse gases, the global temperature will rise by 1.5-4.5 degrees in 2 1 century, and the sea level may rise by 20- 1.40 cm only due to the expansion of seawater. In the past 100 years, the sea level rose by about1-1.5mm every year due to the global temperature rise. If 2 1 century is full
