Researchers explore future economic and climate scenarios using global integrated assessment models to understand long-term interactions between human development environmental changes. However, differences in trade modeling approaches are an important source of uncertainty these types assessments, particularly for regional projections. In this study, we modified the Global Change Analysis Model (GCAM) include a novel logit-based Armington structure, examine two trade: (1) approach that...
The buildup of atmospheric CO2 since 1958 is surprisingly well explained by the simple premise that 57% industrial emissions (fossil fuel burning and cement manufacture) has remained airborne. This accounts for rise both before after 1980 despite a decrease in growth rate fossil emissions, which occurred at time, itself should have caused airborne fraction to decrease. In contrast, prior was not simply proportional cumulative notably included period during 1940s when stalled continued...
Computable general equilibrium (CGE) models provide valuable insights into economy-wide impacts of anticipated future structural changes in the transportation sector, yet few CGE offer detailed representations. We use an enhanced Applied Dynamic Analysis Global Economy (ADAGE) model to incorporate disaggregated modes and technologies on-road passenger freight transportation. assess these inclusions on U.S. patterns, energy consumption greenhouse gas emissions. Simulating illustrative global...
Abstract An equilibrator is presented that designed to have a sufficient equilibration time even for insoluble gases, and minimize artifacts associated with not equilibrating the total gas tension. A tension device was used balance pressure inside The has an e-folding of 7.36 ± 0.74 min oxygen isotopes, allowing changes on hourly scales be easily resolved. delivers “equilibrated” air at flow rate 3 mL min−1 isotope ratio mass spectrometer. high sampling would allow interfaced many potential...
