Climate change has surpassed the category of pure environment problem and become a focal issue in international relations. Driven by climate change, new changes have taken place in the evolution of geopolitical pattern. (1) Geopolitical contention expands into new fields and regions. (2) Measures and tools of geopolitical contention become more diversified. (3) Main bodies of geopolitical gambling are divided into different groups. With the development of politicization, climate change has become the significant driving force that can influence the evolution of geopolitical pattern. Measures, sphere and contents of geopolitical contention changed dramatically, carbon emission permits, carbon tariff and new energy technology turned into the key points of geopolitical contention. Climate change acts on the evolution of geopolitical pattern through three main paths: "Feedback effect", "Trace back effect", and "Ripple effect", and they exert influence on geopolitical pattern with three impacts: "Depression effect", "Traceability effect", and "Diffusion effect". We draw several conclusions from the analysis: (1) Climate change gradually becomes one of the most active driving forces to impact on the evolution of geopolitical pattern in the present world and it diversifies the geopolitical targets. (2) Climate change generates new geopolitical tools. The developed countries use climate change as a "Lever" to pry strategic resources like energy and grain and the geopolitical means are in a more secretive way. (3) Low-carbon technology, with new energy technology as the core, becomes the key factor of geopolitical influence and power transition. Those who can take advantage of new energy technologies will occupy the leading position in future's climate change negotiations and geopolitical competition.展开更多

The results showed that the surge in population migration from Gansu and Shaanxi to Xinjiang during 1760–1820 was caused by extreme climate events(droughts and floods) and population pressure in Gansu and Shaanxi. During 1760–1880, the climate in Xinjiang was unusually cold and humid, which was highly conducive to abundant regional water resources. This provided favorable conditions for farmland irrigation and further promoted agricultural cultivation, population growth, and town development within this region. Additionally,the interactions between climate change and the above-mentioned social factors, which acted as driving forces, spurred the reform in the administrative system of Xinjiang whereby the military administration system was transformed to a province administration system. Through this reform, the Qing government managed to restore peace and stability in Xinjiang. This study contributes to a better understanding of climate-related population migration and enhances our knowledge of the impact-response chain between climate change, ancient social developments, and political coping strategies, especially in regional administrative reform.展开更多
