气候是大气、海洋、大陆和整个生物圈每时每刻都在发生着的相互作用的结果。由于它是这样的复杂,要想在既定的理论框架中来描述气候现象,的确是困难的。科学家们所关心的根本问题是气候变化问题。七十年代里,世界上有些地区,如萨赫勒,遭受到干旱,结果给人民经济生活带来了重大的灾难。我们现在正竭尽全力想弄清楚达种现象究竟是一种偶然性的危帆、一种多少具有某些稳定性的周期循环中的随机起伏,还是我们这个星球温度增高的总趋势的一种征兆,即一个相当大的破坏时期的开始。
Climate is the result of the interaction of the atmosphere, ocean, continent and the entire biosphere all the time. Because of its complexity, it is indeed difficult to describe climate phenomena in a given theoretical framework. The fundamental issue that scientists are concerned with is climate change. In the 1970s, some parts of the world, such as the Sahel, suffered from drought and as a result brought major disaster to the people's economic life. We are now doing our utmost to find out whether the phenomenon of speculation is a contingent crisis, a measure of the degree of random fluctuations in periodic cycles of some stability, or an indication of the general trend of our planet's warming, The beginning of a rather damaging period.
