常春藤生活英语【59】改变世界的６度Ｃ

News about global warming is everywhere. There are a number of theories and ideas about this environmental crisis¹. Some of the information is true, some is false, and some is impossible to prove or disprove. Recently, Mark Lynas, a British scientist, released what might be the scariest news yet. He says if Earth warms up by just six degrees, our entire world could change. This could harm billions of people. It could also happen before the end of the century.
This month, National Geographic² Channel looks at this theory in Six Degrees Could Change the World. According to the theory, a change of six degrees could cause major disasters. Numbers of wildfires and typhoons might increase around the world. Rivers and lakes might dry up in some places, and glaciers³ might melt. There is also evidence that this is already happening. In the UK, warmer weather is completely changing what farmers can grow. Storms in the US and fires in Australia have destroyed buildings and lives. Our world is definitely changing, and the results might be fatal.

全球暖化的新闻随处都能听到。有许多理论和想法都跟这个环保危机有关。这些信息有些是真的，有些是假的，有些则完全无法证实或反驳。英国科学家马克?林纳斯最近发布一则到目前为止，可能是最可怕的新闻。他说假如地球温度再升高六度，整个世界或许都会改变。这可能危害到几十亿人。这个现象也可能在本世纪末之前发生。

本月份，国家地理频道将在《改变世界的６度Ｃ》节目中探讨这个理论。根据这个理论的说法，六度的气温变化会引起后果不堪设想的灾害。全球野火和台风的数量也许会增加。某些地方的河川跟湖泊可能干涸，冰河也可能溶化。也有证据指出这种现象已经发生。在英国，较为温暖的天气正彻底改变农夫可以种植的作物。美国的暴风雨和澳洲的火灾则摧毁了无数的建筑物和生命。我们的世界的确正在改变，而其后果可能是毁灭性十足的。
