參考譯文：在過去的幾年中，氣候科學中最大的`問題就在於，為什麼，自從本世紀以來，即使大氣中吸熱的二氧化碳氣體聚集的越來越多，地球表面平均的氣溫也沒有上升。
“pause” in global warming has been seized on by those skeptical thathumanity needs to act on to curb greenhouse-gas emissions or even (in the case ofsome extreme sceptics) who think that man-made global warming itself is a fantasy.
詞彙突破：seized on 抓住(並利用);
those skeptical that +句子:這種用法在傳統的語法中並不多見，但是在經濟學人這樣的雜誌中還是挺多的。
其實就等於those who doubt that+句子 ,大家記住就好。
參考譯文：全球變暖的暫停被這些人抓住並加以利用。他們本來就不認為人類需要採取行動來控制溫室氣體的排放。甚至其中一些極端的質疑者認為人為的全球變暖本身就是一種幻想而已。
