This paper analyzes the mean fine particulate (PM_2.5) and ozone (O₃) levels in 2025, and high-impact air-pollutant events and compound events in China.

Based on a 20-year field nitrogen addition experiment, this study demonstrates that long-term high nitrogen deposition does not reduce belowground carbon allocation in tropical forest plants; rather, it induces a physiological adaptation—upregulation of root exudation—to actively mobilize soil phosphorus, thereby sustaining productivity and offering a key mechanistic explanation for the persistence of tropical forest carbon sinks under chronic nitrogen enrichment.

A new international study, published in Nature Geoscience, provides a quantification of the air-sea global carbon cycle and how it might change in a warming climate.

A new international study quantifies, for the first time, how data losses in ocean monitoring would severely degrade the ocean heat estimates that underpin weather prediction, El Niño forecasting, and fisheries management.

A new international study, published in Science Advances, fully accounts for what is driving the world's rising oceans over six decades.
