全球变暖原因探讨
|
摘要
南斯拉夫气候学家米兰柯维奇早在20世纪30年代提出理论,地球轨道三要素(地球轨道的偏心率、地轴的倾斜度和春分点的位置)的自然小波动影响太阳辐射强度,导致地球上的气候发生变化.笔者经过计算得出结论,认为全球变暖的主要原因不仅是大气中温室气体(二氧化碳、甲烷等)的浓度变高所致,也包括因为地球在围绕太阳旋转的过程中,其自转轴相对于太阳的黄道面夹角发生变化引起的.在地球上,由于各种内部(如地震、大风、海潮,甚至火箭的发射等)和外部(如太阳本身、外星球及陨石的冲击等)扰动的存在,这个夹角应该是有变化的.不论这个夹角变大还是变小,积以时日,都会导致地球气候变化.
In the early 1930s ,the distinguished Yugoslavian climatologist Milankovich had already developed the theory that a tiny ? uctuation in the eccentricity ratio of Earth's orbit ,or the obliquity of Earth's spin axis ,even in the position of the first point of Aries may render a direct in? uence on the solar radiation's range and degree;therefore ,causes the climate change on Earth .Based on a comprehensive calculation ,the authors came to the conclusion that besides the robust increase of greenhouse gases(CO2 ,CH4 ,etc .) , there are also other factors that cause global warming , but this paper focuses on the angular change between Earth's axis and its ecliptic plane .According to the paper ,both the internal variables(earthquake ,wind ,tide ,rocket's launching ,etc .) and the external variables(the sun's motion , other planets' motion ,meteoric stone ,etc .) impacted greatly on this angle .What's more ,no matter to what degree this angular change arrives at ,it inevitably causes the climate change on Earth throughout the time .
