Recent methane surges reveal heightened emissions from tropical inundated areas.

Record breaking atmospheric methane growth rates were observed in 2020 and 2021 (15.2±0.5 and 17.

Trends and drivers of anthropogenic NO emissions in China since 2020.

Nitrogen oxides (NO), significant contributors to air pollution and climate change, form aerosols and ozone in the atmosphere. Accurate, timely, and transparent information on NO emissions is essential for decision-making to mitigate both haze and ozone pollution. However, a comprehensive understanding of the trends and drivers behind anthropogenic NO emissions from China-the world's largest emitter-has been lacking since 2020 due to delays in emissions reporting.

Accelerating the energy transition towards photovoltaic and wind in China.

China's goal to achieve carbon (C) neutrality by 2060 requires scaling up photovoltaic (PV) and wind power from 1 to 10-15 PWh year (refs. ). Following the historical rates of renewable installation, a recent high-resolution energy-system model and forecasts based on China's 14th Five-year Energy Development (CFED), however, only indicate that the capacity will reach 5-9.

Wetland emission and atmospheric sink changes explain methane growth in 2020.

Atmospheric methane growth reached an exceptionally high rate of 15.1 ± 0.4 parts per billion per year in 2020 despite a probable decrease in anthropogenic methane emissions during COVID-19 lockdowns.

Stringent Emission Controls Are Needed to Reach Clean Air Targets for Cities in China under a Warming Climate.

Quantifying the threat that climate change poses to fine particle (PM) pollution is hampered by large uncertainties in the relationship between PM and meteorology. To constrain the impact of climate change on PM, statistical models are often employed in a different manner than physical-chemical models to reduce the requirement of input data. A majority of statistical models predict PM concentration (often log-transformed) as a simple function of meteorology, which could be biased due to the conversion of precursor gases to PM.
