Many scientists agree that the glaciers around the world could disappear in this century, much faster than we thought. ②As we all know, the reason for this is global (全球的) warming. When certain gas such as carbon dioxide (CO ) is largely emitted (排放) into the atmosphere, it causes the greenhouse effect (效应) which makes Earth warmer. ③As Earth becomes warmer, glaciers melt quickly, and dark rocks are uncovered. Then these rocks take in more heat, causing the temperature to rise. As ... ...
