据英国 New Scientist 1996年4月6日报道,美国罗德岛大学的东特(S.D’Hondt)和宾夕法尼亚大学的阿瑟(M.Arthur)的研究发现,在6600万年前,即近恐龙时代的晚白垩纪时期,赤道处海洋的温度要比今天的为低,但是,那时地球是个宜人的地方,两极都没有冰雪覆盖。温室效应的简单模型可以解释温暖的两极,但对赤道的低温却无能为力。无疑,该发现是对气候学家的一次挑战,而且,它将导致对目前的全球升温对赤道影响的预测的再思考。
According to the British New Scientist reported on April 6, 1996, a study by S. D’Hondt of the University of Rhode Island and M. Arthur of the University of Pennsylvania found that 66 million years ago, that is, nearly During the late Cretaceous period of the dinosaurs, the temperature of the ocean at the equator was lower than today’s. However, when the earth was a pleasant place, there was neither snow nor ice at both poles. A simple model of the greenhouse effect can explain the warmth of the poles, but can not do anything about the low temperatures of the equator. Undoubtedly, the discovery is a challenge to climatologists and it will lead to a rethinking of the current global projections of the effects on the equator.
