This climatic evolution has been punctuated by several warming such as the peak Cenozoic warmth at 52 Ma, the late Oligocene warming at ~25 Ma and the Mid-Miocene Climatic Optimum at 17–14 Ma. Concurring with the global temperature changes, the Asian paleoenvironment has been modulated by the global cooling and the tectonic uplift during the Cenozoic, but what have driven the global climatic changes remains unresolved. In this review paper, I hypothesize that a threshold CO_2 level in combination with favorable orbital configuration, ocean circulation,enhanced ice albedo and possible roles of silicate mineral and basalt weathering together facilitated the development of glaciations in the Cenozoic and the past temperature change. The synchronous variations between Earth's surface temperature and atmospheric CO_2 level may indicate that the atmospheric CO_2 content is the direct driving force for the global climatic cooling, but this hypothesis needs testing by using high-resolution geological record and paleoclimatic modeling.展开更多

Amid continuous social change, economic space has seen a reassertion of trade protectionism, while political space is facing the rise of populist parties. Britain's exit from European Union has dealt a heavy blow to the process of European integration, once again empowering national and local levels through traditional sentiments and redefining the international order in the new era of globalization. In this new era, as global economic integration slows down, the Chinese plan of the Belt and Road Initiative focuses on building a "community of shared future for mankind," "with unwavering efforts to advance and guide economic globalization trends." Its open and inclusive strategic content; its strategic orientation of mutual learning; and its strategic aim of development and coexistence on an economic basis under political intermediation and through the guidance of culture highlight the integration of economic space, mutual trust in political space, and inclusiveness incultural space. The spatial extension of the strategic mutual trust of the Belt and Road Initiative originates in rational reflection on fundamental emotional expectations; instrumental sharing of benefit; emotional involvement; and value judgments. Based on the fact that the population along its route are recipients of the values of strategic mutual trust and also makers of its meanings, we can divide the promotion of the Belt and Road Initiative into cultural resonance zones, zones that activate the interests of different parties, and zones that promote identification, combining regional nodes and cooperative content. In order to enhance the degree of congruence of strategic mutual trust, we should disseminate these values in a way that combines charm, comprehensiveness and accuracy.展开更多
