A study of trends in body morphology, overweight, and obesity in Chinese adults aged 40–59 years
Without stronger interventions, overweight and obesity rates among middle-aged adults are likely to continue to increase in the future, and coordinated efforts are needed to slow down the obesity epidemic and improve the physical health of middle-aged adults
Field Study
According to a UNICEF report, there are 65.17 million children living in poverty‐stricken areas of China, accounting for 21.9% of the national child population. Authorities focus on economic aid and basic safety protection for vulnerable children but lack support in psychological, emotional, and social areas. While international scholars have recognized sports‐based social projects (SBSPs) as an effective tool for promoting child development, the…

Emergent constraints on the future East Asian winter surface air temperature changes
In East Asia, the climate variability in boreal winter is dominated by the East Asian winter monsoon, one of the most energetic monsoon systems that can lead to disasters. The key variable, the East Asian winter surface air temperature (SAT), has significantly changed over the past century and has substantially impacted agriculture, ecosystems, economics, and public health. However, its projections are limited by considerable uncertainties. Here,…

Spatial correlation network of pollution and carbon emission reductions coupled with high-quality economic development in three Chinese urban agglomerations
Measurement of carbon emissions from marine fisheries and system dynamics simulation analysis
Recent regional warming across the Siberian lowlands
The northern mid-high latitudes experience climate warming much faster than the global average. However, the difference in the temperature change rates between permafrost and non-permafrost zones remains unclear. In this study, we investigated the temporal changes in temperature means and extremes across the Siberian lowlands (<500 m) over the past six decades (1960–2019) using in situ observations and reanalysis data. The results show that perma…
Basin-Scale Pollution Loads Analyzed Based on Coupled Empirical Models and Numerical Models

Biases of the wintertime Arctic Oscillation in CMIP5 models
Distinct biases are found in the pattern and teleconnections of the Arctic Oscillation (AO) in 32 climate models that participate the Coupled Model Intercomparison Project Phase 5 (CMIP5). Compared with observations, the Pacific (Atlantic) center of AO is excessively strong (weak) in most of the 32 CMIP5 models, and the AO-related surface air temperature anomalies are generally weak over the Eurasian continent and North America. These biases are …
History and mechanisms for the expansion of the Badain Jaran Desert, northern China, since 20 ka
Desert landscapes are widely distributed in the arid northern China. The Badain Jaran Desert (BJD) is located north-west of the Tengger Desert (TD) and Ulan Buh Desert (UBD), with the Yabrai and Bayan Ulan Mountains separating the BJD from the TD and UBD. Many sand belts with an orientation of NW-SE, which is similar to that of the prevailing sand-transporting winds, connect the BJD with the TD and UBD, forming the sand transportation routes from…
