改變世界的六度

You know about six degrees of separation. But what about six degrees to extinction?

Scientists predict that global temperatures will rise by between one and six degrees over the course of this century and author Mark Lynas paints a chilling, degree-by- degree picture of the devastation likely to ensue unless we act now.

A new show on National Geographic Channel, "Six Degrees Could Change the World" narrated by Alec Baldwin, investigates the startling

theory that earth average temperature could rise six degrees Celsius by the year 2100.

"Six Degrees Could Change the World" explores the potential impacts of global warming degree-by-degree through six degrees over the next

hundred years. Filmed on five continents, the program tracks the world's top climate researchers and follows ranchers, photographers, and everyday people to uncover climate trends.

Utilizing cutting-edge CGI and hard-hitting scientific data, the HD special will reveal how each potential degree affects us on all levels ?from the bottom of our deepest oceans to the tops of our highest mountains.

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。英國科學家馬克‧林納斯最近發佈一則可能是最可怕的新聞。他説假如地球温度再升高六度，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。

國家地理頻道在《改變世界的6度》節目中探討這個理論。根據這個理論的説法，六度的氣温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幹涸，冰河也可能溶化。也有證據指出這種現象已經發生。在英國，較為温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。
