News about global warming is everywhere. There are
a number of theories and ideas about this environmental crisis. 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 Geographic 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 glaciers 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.
全球暖化的新聞隨處都能聽到。有許多理論和想法都跟這個環保危機有關。這些資訊有些是真的，有些是假的，有些則完全無法證實或反駁。英國科學家馬克•林納斯最近發佈一則到目前為止，可能是最可怕的新聞。他說假如地球溫度再升高六度，整個世界或許都會改變。這可能危害到幾十億人。這個現象也可能在本世紀末之前發生。
本月份，國家地理頻道將在《改變世界的６度Ｃ》節目中探討這個理論。根據這個理論的說法，六度的氣溫變化會引起後果不堪設想的災害。全球野火和颱風的數量也許會增加。某些地方的河川跟湖泊可能乾涸，冰河也可能溶化。也有證據指出這種現象已經發生。在英國，較為溫暖的天氣正徹底改變農夫可以種植的作物。美國的暴風雨和澳洲的火災則摧毀了無數的建築物和生命。我們的世界的確正在改變，而其後果可能是毀滅性十足的。
