| 摘 要： | 20世纪80年代以来，地面气象观测结果表明全球气温在明显升高，而探空资料和卫星遥感资却表明低层大气在降温，这使得人们对于全球变暖问题提出了质疑。通过对近100多年来冰冻圈各组成要素（冰川、积雪、冻土、海冰等）变化的综合分析，并结合全球不同地区的冰芯记录，证明了20世纪全球气候是在变暖，指出开展冰冻圈（尤其是冰盖、积雪、冻土和海冰）与大气／海洋之间相互作用（影响和响应）过程研究的必要性和迫切性。

| Abstract: | The apparent difference between the thermometer estimated surface warming and the air temperature decreasing in the lower troposphere estimated from satellites and radiosondes in recent years, makes the global warming being as an open question. By comprehensive analyses for the variations of the every component of the cryosphere, such as glacier, snow cover, permafrost and sea ice, etc., together with the records of ice cores from different areas, it was verified that climate was warming over the global surfaces, both in lower and high altitudes, in the 20th century. Moreover, it was pointed out that it is necessary to study the interaction process between the cryosphere and atmosphere/ocean for understanding the Earth climate system. |
