Flux and Radiocarbon Evidence of Urban Carbon Emission Reductions under 1 Climate Mitigation Policies

Rapid Increase in Geogenic CO 2 Emissions from Antarctic Permafrost

Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO 2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic deg...

CO2 Emissions From Rivers Draining the Tibetan Plateau Reveal Substantial Increases Over the Past 20 Years

Inland water CO2 emissions are a critical component of the global carbon cycle, yet their magnitude and long‐term response to climate change remain poorly constrained, primarily because of uncertainties in the air–water CO2 concentration gradient. This knowledge gap is particularly pronounced on the Tibetan Plateau, wh...

The Dominance and Future Variations of Background Ozone in China under 1 Different Climate and Emission Scenarios

Atmospheric CH4 plateau sustained by NOx emission rise and southward shift

Global and national lime process emissions and carbonation sink from 1930 to 2024

Accurate quantification of lime process emissions and subsequent carbonation uptake is needed to represent the lime carbon cycle in global carbon-budget assessments. We developed a source-prioritized and internally cross-checked dataset for 1930–2024 by harmonizing USGS statistics, national statistical yearbooks, ind...

THE DYNAMICS OF CO2 AND CH4 EMISSIONS AND ABSORPTION BY LAND AND OCEAN SURFACES IN THE 21st CENTURY: CURRENT ESTIMATES AND TRENDS

Modern climate change is characterized by a rapid increase in global mean temperature, which has already risen by approximately 1.3–1.5℃ compared to pre-industrial levels. Alongside this warming, the frequency and intensity of extreme weather events, including heatwaves and heavy precipitation, have increased significa...
