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.

證據確鑿。哪裡有永久冰 - 格陵蘭島，南極洲，阿爾卑斯山，喜馬拉雅山，冰融化。一直是山高的人誰都會注意到這一事實。科學家都認為，這種熔化的原因是很簡單的。地球的大氣層升溫。融化的冰，反過來，導致海平面上升作為多餘的水從融化的冰倒入海洋。 ，海平面已經上升約8英寸（20厘米）近年來，科學家們相信他們可以上升到2100年至少還有20英寸（50厘米）。這可能危及許多人口稠密的沿海地區。海岸佛羅里達州，尼羅河三角洲，孟加拉國和許多其他領域將結束在水中。隨著氣溫上升，海洋溫度也在不斷提高。這帶來了天氣模式的變化，更頻繁和更嚴重的風暴。海水溫度上升是在南部海洋珊瑚礁死亡的因素之一。這些珊瑚礁是世界魚類的65%的自然家園。當...
