The authors exploit the remarkable connection between the Chinese climate trends and the annular modes by partitioning the trends into components linearly congruent with and linearly independent of the annular modes. Results show that the winter hemisphere annular mode has closer connection to Chinese climate than the summer one, e.g., the wetting JJA (June-July-August) rainfall trend along the Yangtze River valley and the associated temperature trends are significantly linearly congruent with the trend of the southern annular mode, while the JFM (January-February-March) climate trends are closely linked to the northern annular mode. The seasonal differences of a meridional wave-train-like chain across the equatorial Pacific associated with the annular modes are responsible for the seasonal-dependent connections to Chinese climate. 展开更多

The way that humans think about the earth certainly affects the way that they relate and behave towards the earth and all its life forms. The various ideologies or worldviews that humanity has experienced such as dualism, capitalism, holism, animism, ubuntu, ukama, vital force, colonialism, and so forth are all different ways of thinking and relating to the earth. The paper argues that dualistic ways of thinking or viewpoints that radically separate the human as distinct from the earth are hostile to both human and earth flourishing. It further argues that the ecological crisis which has witnessed the destruction and pollution of the ecosystems and other devastations cannot be solved when humans continue to see the earth as an object for conquest and exploitation. Using a critical hermeneutics method, the paper affirms that the African principle of relationality can help in mitigating the environmental crisis. It finds and concludes that if this principle is radically practiced, a better environment will be created. 展开更多
