Atmospheric CH4 plateau sustained by NOx emission rise and southward shift

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...

What controls tropospheric carbon monoxide in the remote Southern Hemisphere?

Recent Increase of Greenhouse Gas Emissions from Cryosphere-Influenced Reservoirs under Climate Change.

Global warming leads to cryosphere degradation, transferring large amounts of terrestrial carbon and nitrogen to reservoirs, which may accelerate the release of greenhouse gases (GHGs) to the atmosphere. However, the spatial dynamics and decadal trends of GHG emissions from these reservoirs remain elusive. Here we comp...

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...

Methane Emissions From U.S. Lakes Dominated by Ebullition, Shallow Zones, and Anthropogenic Drivers

Lakes are globally important sources of atmospheric methane (CH4), yet a process‐based understanding of their emissions and drivers at regional scales remains limited. Here we developed and applied a one‐dimensional lake model to 42,948 natural lakes across the contiguous United States (CONUS). Simulations indicate tha...

Warming Amplifies the Variability of Methane Emissions From a Coastal Wetland

Climate warming is expected to increase methane (CH 4 ) emissions from coastal wetlands, but its effects on the temporal dynamics of emissions remain poorly resolved. Because short‐lived high‐emission events are poorly captured by low‐frequency monitoring and by existing models, warming‐driven increases in variab...
