Climate models predict that the concentration of water vapor in the upper troposphere could double by the end of the century as a result of increases in greenhouse gases. Such moistening plays a key role in amplifying the rate at which the climate warms in response to anthropogenic activities, but has been difficult to detect because of deficiencies in conventional observing systems. We use satellite measurements to highlight a distinct radiative signature of upper tropospheric moistening over the period 1982 to 2004. The observed moistening is accurately captured by climate model simulations and lends further credence to model projections of future global warming.
气候模型预测，由于温室气体增加，到本世纪末对流层上部的水汽浓度可能会翻倍。这种变湿现象在放大气候因人类活动而变暖的速率方面起着关键作用，但由于传统观测系统存在缺陷，一直难以被探测到。我们利用卫星测量突出显示了1982年至2004年期间对流层上部变湿的独特辐射特征。气候模型模拟准确地捕捉到了观测到的变湿现象，这进一步证明了模型对未来全球变暖预测的可信度。
