A new study finds that despite continued growth in global fertilizer inputs, nutrient use efficiency in major crops has not improved correspondingly and remains generally low. This underscores that "high input, low efficiency" remains a systemic challenge facing global agriculture.
A research team from the Institute of Earth Environment of the Chinese Academy of Sciences developed a semi-automated microanalytical method to quantify atmospheric plastic particles and their cross-compartmental fluxes—airborne, dustfall, rain, snow, and dust resuspension—in two major Chinese megacities: Guangzhou and Xi'an.
A research team led by Prof. NIU Shuli from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences, in collaboration with international partners, conducted a 4,200-kilometer survey across the alpine grasslands of the Qinghai-Tibet Plateau. By integrating regional survey data with global datasets on plant diversity and productivity, the team provided the first empirical evidence that biodiversity’s stabilizing effects shift over time in natural ecosystems.
A new international analysis has found that the world's oceans absorbed more heat in 2025 than in any year since the start of modern measurements. The 2025 heat gain totalled 23 zetta joules—equivalent to roughly 37 years of global primary energy consumption at 2023 levels, when the world used about 620 exajoules annually.
Researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences have conducted a study revealing the robust weakening of the CGT under global warming and elucidating its effects on regional heatwaves.
A research team led by Prof. CHEN Hongsong from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences has revealed that lithology-driven soil properties play a critical role in shaping latitudinal variation in forest species composition in southwestern China.
