【專(zhuān)八mini系列】溫室效應(yīng)（4/7）

Thirdly, what are the possible consequences caused by excessive greenhouse effect? It directly results in quick increase of the average global temperature. Today, the increase in the Earth's temperature is increasing with unprecedented speed. To understand just how quickly global warming is accelerating, consider this: during the entire 20th century, the average global temperature increased by about 0.6 degrees Celsius, while by using computer climate models, scientists estimate that by the year 2100 the average global temperature will increase by 1.4 degrees to 5.8 degrees Celsius, which is rather a big leap from the last century. Meanwhile, a majority of the scientists agree that even a small increase in the global temperature would lead to significant climate and weather changes, affecting cloud cover, precipitation, wind patterns, the frequency and severity of storms, and the duration of seasons.
