全球气候变化引起大气、海洋、陆地水、冰川等地表流体质量在地球表面的重新分布，并引起地球自转变化和地球重力场变化。通过空间大地测量技术，可以高精度获取地球自转变化数据和地球重力场时变数据，反演地表流体质量在全球和区域的变化情况，揭示地表流体质量变化与全球气候变化的关系。地球自转变化也和厄尔尼诺、北大西洋涛动等气候涛动密切相关，并与地表流体质量的长期变化相关。因此，利用地球自转变化和时变重力场变化观测数据，可以更好地研究全球气候变化。

The geophysical lfuids, such as the atmosphere, the ocean, the land-water and the ice-sheet etc. are constantly changing on the Earth’s surface, under the condition of global climate change. These geophysical lfuid changes cause the variations of the Earth’s rotation and the Earth’s gravity ifeld. Using the space-geodesy techniques, we can acquire high precision variation data of the Earth’s rotation and the Earth’s gravity ifeld, and then invert the geophysical lfuid changes in the Earth’s surface to explore the relationship between either the Earth’s rotation or the Earth’s gravity ifelds and the global climate change. Otherwise, the Earth’s rotation variations are correlated with the climate oscillation, such as El Ni?o, North Atlantic Oscillation, and also correlated with the long-term change of geophysical lfuid changes on the Earth’s surface. Thus, observing variation data from the Earth’s rotation and the Earth’s gravity ifelds, will help us have a deeper understanding of the global climate change.
