When Al Gore, the former US vice-president, starred in the documentary An Inconvenient Truth back in 2006, it had a big impact on the green debate. Never mind the fact that most of the documentary's viewers did not really understand the science behind global warming, or that the issue of climate change had been bubbling away, often unnoticed, for years. The fact that An Inconvenient Truth featured dramatic images (melting ice caps, marooned polar bears) and a powerful person speaking with passion (Gore) suddenly gave a focus to the formerly nebulous green issue. The complexities of climate change no longer seemed quite so off- putting or dull, even to US voters.
2006年，美國前副總統(tǒng)戈爾(Al Gore)在紀錄片《難以忽視的真相》(An Inconvenient Truth)中做解說，對“綠色辯論”產(chǎn)生了巨大影響。紀錄片的多數(shù)觀眾并非真的明白全球變暖背后的科學(xué)，也不了解氣候變化這個問題早已被討論了多年，往往無人注意，不過這都不要緊。《難以忽視的真相》展示了令人瞠目驚舌的畫面（融化的冰蓋、孤立無援的北極熊），加上一位大人物（戈爾）的激情解說，使人們突然聚焦于以前模糊不清的綠色問題。即使對于美國選民而言，氣候變化的復(fù)雜性看上去不再那么討人厭煩或者沉悶。
