科學(xué)揭秘:恐龍滅絕的真正原因

        Researchers studying fossils in Norway have discovered that the world's seas plummeted 9C from 13C to just 4C around 137million years ago.

　　調(diào)查者在研究挪威的恐龍化石時(shí)發(fā)現(xiàn)，在一億三千七百萬年之前，海水溫度從13度急劇降到4度。

　　They believe this was caused by a sudden change in the Atlantic Gulf Stream - a phenomenon many experts fear is about to happen again.

　　科學(xué)家們認(rèn)為造成這一溫度驟降的原因是墨西哥暖流造成的，而且專輯們認(rèn)為這一現(xiàn)象至今仍可能發(fā)生。
