As next month's Copenhagen conference approaches, politicians should not be distracted by the apparently growing volume of sceptical voices challenging the need for global action against climate change. Some of the sceptics may have scientific backgrounds but they are not in the mainstream of contemporary climate research. The real experts – hundreds of scientists worldwide who are examining the link between climate and carbon dioxide emissions – have no doubt that man-made global warming is a real crisis that must be addressed urgently.
隨著下個月的哥本哈根會議日益臨近,質疑全球共同對抗氣候變化的必要性的論調明顯增多,但政界人士不應爲此而分心。一些懷疑者可能有科學背景,但他們不是當代氣候研究的主流羣體。真正的專家是世界各地研究氣候變化與二氧化碳排放之間的關係的數以百計的科學家,他們堅信,人爲造成的全球變暖是一個必須抓緊時間解決的切實危機。
