Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective proces...
Asymmetry in CO2 emissions and removals could skew climate targets
carbon dioxide emissions climate targets carbon dioxide removals
2021/8/4
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals -- and assuming such a balance could lead...
Sensitivity of simulated CO2 concentration to regridding of global fossil fuel CO2 emissions
fossil fuel CO2 emissions
2014/12/19
Errors in the specification or utilization of fossil fuel CO2 emissions within carbon budget or atmospheric CO2 inverse studies can alias the estimation of biospheric and oceanic carbon exchange. A ke...

2014/12/19
This study investigates the capacity of a prognostic biosphere model to simulate global variability in atmospheric CO2 concentrations and vegetation carbon dynamics under current environmental conditi...
The Community Land Model underestimates land-use CO2 emissions by neglecting soil disturbance from cultivation
Community land model planting harvesting crops planting on soil carbon biogeochemical model cultivation soil carbon
2014/12/18
The Community Land Model (CLM) can simulate planting and harvesting of crops but does not include effects of cultivation on soil carbon decomposition. The biogeochemistry model DayCent does account fo...
Global high-resolution simulations of CO2 and CH4 using a NIES transport model to produce a priori concentrations for use in satellite data retrievals

The Greenhouse gases Observing SATellite (GOSAT) measures column-averaged dry air mole fractions of carbon dioxide and methane (XCO2 and XCH4, respectively). Since the launch of GOSAT, model-simulated...
On the parallelization of atmospheric inversions of CO2 surface fluxes within a variational framework
atmospheric inversions CO2 surface fluxes variational framework
2014/12/12
The variational formulation of Bayes' theorem allows inferring CO2 sources and sinks from atmospheric concentrations at much higher time–space resolution than the ensemble or analytical approaches. Ho...

The biogeochemical dynamics of carbon in the ocean is a subject of fundamental interest to environmental studies. In this context, we have implemented a ten year run of the Brazilian Earth System Coup...
Effects of CO2 Injection on the Seismic Velocity of Sandstone Saturated with Saline Water
Biot-Gassmann Theory CO2 Geological Sequestration
2013/3/11
Geological sequestration (GS) of carbon dioxide (CO2) is considered as one of the most promising technologies to reduce the amount of anthropogenic CO2 emission in the atmosphere. To ensure success of...
Dominant Factors of the Nature Regulating CO2 Release from Boreal Forest Land
Fragmentation Global Warming High-Latitude Forest
