Development of a REgion‐Specific Ecosystem Feedback Fire (RESFire) Model in the Community Earth System Model
(2020-04-01)
Fires play a critical role in modulating regional and global climate through disturbances on
meteorological, biogeochemical, and hydrological processes, while fires are strongly affected by climate,
terrestrial ecosystems, ...
Fitness implications of seasonal climate variation in Columbian ground squirrels
(2020-04-01)
The influence of climate change on the fitness of wild populations is often studied in the context of the spring onset of the reproductive season. This focus is relevant for climate influences on reproductive success, but ...
Global Nitrous Oxide Emissions From Pasturelands and Rangelands: Magnitude, Spatiotemporal Patterns, and Attribution
(2020-04-01)
The application of manure and mineral nitrogen (N) fertilizer, and livestock excreta deposition are the main drivers of nitrous oxide (N2O) emissions in agricultural systems. However, the magnitude and spatiotemporal ...
Global Pyrogenic Carbon Production During Recent Decades Has Created the Potential for a Large, Long-Term Sink of Atmospheric CO2
(2020-05-26)
Fires play an important role in the terrestrial biosphere carbon cycle, not only through direct carbon release but also contributing to a potential long-term storage as pyrogenic carbon (PyC). PyC is formed through fires, ...
Increased light-use efficiency in northern terrestrial ecosystems indicated by CO2 and greening observations
(2020-04-01)
Observations show an increasing amplitude in the seasonal cycle of CO2 (ASC) north of 45 degrees N of 56 +/- 9.8% over the last 50 years and an increase in vegetation greenness of 7.5-15% in high northern latitudes since ...
Long-term trends in evapotranspiration and runoff over the drainage basins of the Gulf of Mexico during 19012008
(2020-04-01)
The Gulf of Mexico (GOM) is facing large pressures from environmental changes since
the beginning of the last century. However, the magnitude and long-term trend of total water
discharge to the GOM and the underlying ...
Methane emissions from global rice fields: Magnitude, spatiotemporal patterns, and environmental controls
(2020-04-02)
Given the importance of the potential positive feedback between methane (CH4) emissions and climate change, it is critical to accurately estimate the magnitude and spatiotemporal patterns of CH4 emissions from global rice ...
Methane exchange between marshland and the atmosphere over China during 1949-2008
(2020-02-25)
We used a process-based ecosystem model to examine methane (CH4) fluxes in the marshland across China as a result of multifactor global changes during 1949–2008. Our
simulated results show a significant declining rate of ...
Severe Long-Lasting Drought Accelerated Carbon Depletion in the Mongolian Plateau
(2020-02-25)
Paleoclimate records identified a severe drought lasting approximately a decade on the Mongolian Plateau during the 2000s, the severity of which was only exceeded by a single drought during the last two millennia. Under ...
Toward more realistic projections of soil carbon dynamics by Earth system models
(2022-03-03)
Soil carbon (C) is a critical component of Earth system models (ESMs), and its diverse representations are a major source of the large spread across models in the terrestrial C sink from the third to fifth assessment reports ...
Vegetation Functional Properties Determine Uncertainty of Simulated Ecosystem Productivity: A Traceability Analysis in the East Asian Monsoon Region
(2020-04-02)
Global and regional projections of climate change by Earth system models are limited by their uncertain estimates of terrestrial ecosystem productivity. At the middle to low latitudes, the East Asian monsoon region has ...
