問題詳情

The evidence is clear. Wherever there is permanent ice – Greenland, Antarctica, the Alps, the Himalayas –thatice is melting. Anybody who has been to high mountains will have noticed this fact. Scientists agree that the causefor this melting is very simple. The earth’s atmosphere is warming up.The melting ice, in turn, is causing sea levels to rise as the extra water from the melting ice pours into theoceans. Already, sea levels have risen about 8 inches (20 cm) in recent years, and scientists believe they could riseat least another 20 inches (50 cm) by the year 2100. This could put many heavily populated coastal areas at risk.Coastal Florida, the Nile Delta, Bangladesh, and many other areas would end up under water.Along with rising air temperatures, the ocean temperatures are also rising. This has brought changes inweather patterns, with more frequent and more severe storms. Rising ocean temperatures are also one of the factorsin the death of coral reefs in the southern oceans. These reefs are the natural homes to 65 percent of the world’sfish. When the reefs die, so do the fish.The warmer air temperatures are also causing changes in the world’s climate zones. In Europe, the southerncountries along the Mediterranean are already becoming drier and more desert-like. On the other hand, countries innorthern Europe, such as Germany and England, have experienced terrible floods from too much rain. Worldwide,agriculture will soon be negatively affected in many places. Life will become more difficult in the poorer countriesof Asia and Africa, which already suffer from poor soil and lack of water. Millions of people could be forced toleave their homes and countries in search of food and a better life.
