California's carbon mitigation efforts may be thwarted by climate change itself
climate change carbon mitigation ecosystem
2021/8/3
To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers warn that future clim...
Coastal ecosystems worldwide: Billion-dollar carbon reservoirs
ecosystem change climate change carbon storage ecosystem
2021/8/5
Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt mars...
Elevated warming, ozone have detrimental effects on plant roots, promote soil carbon loss
climate warming ozone AMF soil
2021/8/3
Two factors that play a key role in climate change - increased climate warming and elevated ozone levels - appear to have detrimental effects on soybean plant roots, their relationship with symbiotic ...
Dealing with global carbon debt

2021/8/4
As atmospheric concentrations of carbon dioxide continue to rise, we are putting future generations at risk of having to deal with a massive carbon debt. Researchers are calling for immediate action t...
Floods may be nearly as important as droughts for future carbon accounting
photosynthesis carbon accounting flood drought
2021/8/4
In a 34-year global analysis, researchers found that photosynthesis -- an important process for removing carbon dioxide from the atmosphere and storing it in soil -- was controlled by extreme wet even...

Global sensitivity analysis,probabilistic calibration,and predictive assessment for the data assimilation linked ecosystem carbon model
Global sensitivity analysis probabilistic calibration predictive assessment data assimilation linked ecosystem carbon model
2015/8/6
In this paper we propose a probabilistic framework for an uncertainty quantification (UQ) study of a carbon cycle model and focus on the comparison between steady-state and transient simulation setups...
A vertically discretised canopy description for ORCHIDEE (SVN r2290) and the modifications to the energy,water and carbon fluxes
vertically discretised canopy ORCHIDEE (SVN r2290) the energy water carbon fluxes
2015/8/6
Since 70 % of global forests are managed and forests impact the global carbon cycle and the energy exchange with the overlying atmosphere, forest management has the potential to mitigate climate chang...
Improving the ISBACC land surface model simulation of water and carbon fluxes and stocks over the Amazon forest
water and carbon fl uxes surface model simulation
2015/8/6
We evaluate the ISBACC (Interaction Soil Biosphere Atmosphere Carbon Cycle) land surface model
(LSM) over the Amazon forest, and propose a revised parameterization of photosynthesis, including new so...
Tropical troposphere to stratosphere transport of carbon monoxide and long-lived trace species in the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Tropical troposphere long-lived
2014/12/19
Variations in the mixing ratio of trace gases of tropospheric origin entering the stratosphere in the tropics are of interest for assessing both troposphere to stratosphere transport fluxes in the tro...

The North American Carbon Program Multi-scale Synthesis Terrestrial Model Intercomparison Project – Part 2
2014/12/19
Ecosystems are important and dynamic components of the global carbon cycle, and terrestrial biospheric models (TBMs) are crucial tools in further understanding of how terrestrial carbon is stored and ...
Modelling the role of fires in the terrestrial carbon balance by incorporating SPITFIRE into the global vegetation model ORCHIDEE – Part 1: simulating historical global burned area and fire regimes
simulating historical global burned area fire regimes
2014/12/19
Fire is an important global ecological process that influences the distribution of biomes, with consequences for carbon, water, and energy budgets. Therefore it is impossible to appropriately model th...
