4. Greenhouse gases continue to build up in the atmosphere.
5. George Hambley believes that global warming will do good rather than harm to the earth.
Researchers say these changes are having severe effects on animals such as penguins, seals and polar bears. Changes in temperature and wetness in the air can also affect the reproduction of some reptiles and amphibians. For example, the sex of baby painted turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles. In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons.
What’s worse, the glaciers (冰川) of the South Pole are beginning to crack (破裂).

所有科学家都接受这个数据。他们还赞同这种观点：正是由于越来越多 地燃烧化石燃料导致了二氧化碳的增加。那么气温会升到多高？福斯特博士 说，在今后的 100 年里，全球变暖的量可能低到 1～1.5 摄氏度，但是也有可 能高达 5 摄氏度。

然而，科学家们在对待升温的态度上却是大不相同的。一方面，福斯特 博士认为气温升高 5 度的趋势可能导致一场大灾难。她说：“对于未来的气 候，我们不可能作出精确的预测，但是那时的天气可能是很糟糕的。”同意 她的观点的其他科学家认为，全球变暖会导致海平面上升好几米；也有人预 言会出现严重的风暴、洪涝、干旱、饥荒、疫病和物种的灭绝。另一方面， 还有一些人，像科学家乔治·汉布利，反对上面的观点，他们认为我们不必担 心空气中会有高含量的二氧化碳。他们预言说，变暖的情况不会很严重，对 环境的影响也不会太坏。汉布利实际上是这样说的：“二氧化碳含量的增加 实际上是件好事，它使植物生长更快，庄稼产量更高，还会促进动物的生长 ——所有这些都能改善人类的生活。”

所有的科学家赞同这种观点：人们为了生产能量而燃烧化石燃料(如煤、 天然气和石油等)，从而引起了地球温度的升高。这个升温过程的一些副产品 就叫作“温室”气体，其中最重要的就是二氧化碳。贾尼丝·福斯特博士解释 说：“有一种科学家称之为‘温室效应’的自然现象。这种现象发生在大气 层中少量的气体(如二氧化碳、甲烷、水蒸气等)吸收太阳的热量，因而使地 球变暖的时候。如果没有这种‘温室效应’，地球的温度将比现在的温度还 要低 33 摄氏度左右。因此，我们需要这些气体。当我们在大气层中增加了大 量额外的二氧化碳时，问题就来了。这意味着更多的热量被困在大气层中， 从而引起全球温度上升。”
