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

　　调查者在研究挪威的恐龙化石时发现，在一亿三千七百万年之前，海水温度从13度急剧降到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.

　　科学家们认为造成这一温度骤降的原因是墨西哥暖流造成的，而且专辑们认为这一现象至今仍可能发生。

        The temperature drop during the Cretaceous period would almost certainly have wiped out an 'abundance' of the world's dinosaurs.

　　曾经称霸地球显赫一时的恐龙，在白垩纪时代的这次温度巨变中，似乎全都灭绝了。

　　The scientists behind the ground-breaking study claim this would have been the first major step dinosaurs took on their eventual road to extinction.

　　在这次前所未有的研究中，科学家们声称，温度巨变只是恐龙们走上灭绝之路的第一步。

        Dr Gregory Price, he found the drop in temperatures was so severe that numerous species of dinosaur previously living in warm, shallow seas, land and swamps would have died out.

　　格雷戈里普莱西博士发现，这次温度变化实在太剧烈，以至于那些在温暖的海洋、湿地以及沼泽中生活的恐龙种类，都走向灭绝。

　　He said the team's research showed the drop in temperature happened when the Earth was in a 'greenhouse' climate - similar to now.

　　他说他带领的小组所进行的这项调查显示，当地球进入到“温室效应”时期，温度巨变的现象就会出现，而这一现象正与地球现在的处境是很相似的。
