双语趣听精彩世界 第98期:全球变暖谁的错?

 　　英国每日邮报:我们经常说由于人类因为缺少环保意识才导致了地球变暖,但是,事实真的是这样吗?目前这还是个具有争议的话题.

　　全球变暖谁的错?

　　Daily Mail: Was the Earth in a period of global warming or cooling before the 20th century?

　　Attempting to answer this question has thrown up a conundrum¹ for scientists, with some studies showing a warming trend, while others suggesting it cooled until humans intervened².

　　Now a new study hopes to settle the issue by arguing that data points to the fact that Earth's climate has been warming over the past 10,000 years - long before human activity is thought to have changed the climate.

　　It argues that previous research that showed a cooling trend was wrong because it used contradictory³ ice core⁴ data.
