Global climate change and its impact on human beings

With the continuous warming of the climate, the glaciers in the north and south poles, the snow and glaciers in the major peaks will melt and the sea level will continue to rise. By then, Tuvalu, Kiribati, Maldives and island countries all over the world may not exist, and major coastal cities will be submerged by seawater, which will be a disaster for all mankind.

The wanton emission of carbon dioxide and the destruction of forests are the main causes of climate warming.

But as far as the whole natural ecosystem is concerned, there are more reasons. As long as mankind is developing at a high speed, and as long as mankind has the heart to destroy nature, this problem will not be solved.

During the spring tides in February and March, 30% of Tuvalu's land was submerged by seawater. "Someone asked us what is the significance of staying here?" Ernert Evie, Minister of Environment of Tuvalu, said. This month, unprecedented waves swept through Tuvalu beach, and seawater gurgled out of the ground, flooding a large area of farmland, resulting in the death of a large area of crops due to salinization. "I had to evacuate my pigs, and the water flooded their necks," said a resident. The sea doesn't pass through many people's backyards. They also fish in the water for fun.

Funafuti, the capital, is the main atoll of Tuvalu. Almost every inch of land there is occupied by wooden houses, small vegetable gardens and pigsty. The coastline is rapidly retreating, and the island that once appeared on a postcard in Tuvalu, together with the coconut trees on the island, has been swallowed up by the waves. Tuvalu, with a population of over 65,438+/kloc-0.0 million, has a land area of only 26 square kilometers, the highest place is only 5 meters, and it is only 4.5 meters above sea level. In recent years, the drinking water of Tuvalu residents is not guaranteed, so we can only solve some domestic water use by accumulating rainwater and using seawater desalination devices imported from Japan.

Global warming is the culprit.

According to the statistics of the United Nations Intergovernmental Climate Change Monitoring Organization (IPCC), in the next 100 year, the earth's temperature will rise by 1.4 ~ 5.8℃, and the sea level will rise by about 80 cm, which undoubtedly means disaster for Tuvalu.

The Tuvalu government had previously reached an immigration agreement with New Zealand to transfer 80 people to New Zealand every year. Niue, a South Pacific island country, also expressed its willingness to accept the people of Tuvalu. However, the current problem is that Niue is facing the same problems as Tuvalu due to global warming.
