Interactions between reducing CO 2 emissions, CO 2 removal and solar radiation management

Interactions between reducing CO2 emissions, CO2 removal and solar radiation management.

We use a simple carbon cycle-climate model to investigate the interactions between a selection of idealized scenarios of mitigated carbon dioxide emissions, carbon dioxide removal (CDR) and solar radiation management (SRM). Two CO(2) emissions trajectories differ by a 15-year delay in the start of mitigation activity. SRM is modelled as a reduction in incoming solar radiation that fully compens...

Two and Three-Body Interactions between CO, H2O, and HClO4

Intermolecular interactions of different configurations in the HOClO3···CO and HOClO3···H2O dyad and CO···HOClO3···H2O triad systems have been studied at MP2/6-311++G(2d,2p) computational level. Molecular geometries, binding energies, cooperative energies, many-body interaction energies, and Energy Decomposition Analysis (EDA) were eval...

Designing markets for CO 2 emissions and other pollutants

Temporal changes in the emissions of CH 4 and CO from China estimated from CH 4 / CO 2 and CO / CO 2 correlations observed at Hateruma Island

In situ observation of the atmospheric CO2, CH4, and CO mixing ratios at Hateruma Island (HAT, 24.05 N, 123.80 E) often show synoptic-scale variations with correlative elevations during winter, associated with air transport from the East Asian countries. We examine winter (November–March) trends in 1CH4 /1CO2, 1CO /1CO2, and1CO /1CH4 observed at Hateruma over the period 1999 to 2010. To investi...

Photodesorption of ices I : CO , N 2 and CO 2

Context. A long-standing problem in astrochemistry is how molecules can be maintained in the gas phase in dense interand circum-stellar regions. Photodesorption is a non-thermal desorption mechanism, which may explain the small amounts of observed cold gas in cloud cores and disk mid-planes. Aims. The aim is to determine the UV photodesorption yields and to constrain the photodesorption mechani...
