Bulletin sur les gaz à effet de serre. N°8: Bilan des gaz à effet de serre présents dans l’atmosphère, d’après les observations effectuées à l’échelle du globe en 2011
Le présent bulletin, le huitième d’une série de bulletins annuels sur les gaz à effet de serre publiés par l’OMM dans le cadre du Programme de la VAG, rend compte de l’évolution de la concentration atmosphérique des principaux gaz à effet de serre persistants (dioxyde de carbone, méthane, protoxyde d'azote, CFC-12 et CFC-11) et présente un récapitulatif de la contribution des autres gaz. Les cinq principaux gaz contribuent pour 96 %[4] environ au forçage radiatif induit par les gaz à effet de serre persistants

Gaz à effet de serre, résorber les émissions
Spore: le magazine du développement agricole et rural des pays ACP, N°151. CTA, 2011D’après une étude, quelque 12 % des émissions totales imputables au bétail pourraient être supprimés grâce à de simples améliorations de la production, incluant l’adoption de pâtures plus nutritives et l’ajout de faibles quantités de résidus de récoltes ou de céréales.

Carbon dioxide atmospheric vertical profiles retrieved from space observation using ACE-FTS solar occultation instrument
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Foucher P.Y.; Chédin A.; Armante R.; et al. - Copernicus GmbH, 2011Major limitations of our present knowledge of the global distribution of CO2 in the atmosphere are the uncertainty in atmospheric transport and the sparseness of in situ concentration measurements. Limb viewing spaceborne sounders such as the Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS) offer a vertical resolution of a few kilometres for profiles, which is much better than currently flying or planned nadir sounding instruments can achieve. After having demonstrated the feasibility of obtaining CO2 vertical profiles in the 5–25 km altitude range with an accuracy of ...

Evaluating a 3-D transport model of atmospheric CO2 using ground-based, aircraft, and space-borne data
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Feng L.; Palmer P.I.; Yang Y.; et al. - Copernicus GmbH, 2011We evaluate the GEOS-Chem atmospheric transport model (v8-02-01) of CO2 over 2003–2006, driven by GEOS-4 and GEOS-5 meteorology from the NASA Goddard Global Modeling and Assimilation Office, using surface, aircraft and space-borne concentration measurements of CO2. We use an established ensemble Kalman Filter to estimate a posteriori biospheric+biomass burning (BS + BB) and oceanic (OC) CO2 fluxes from 22 geographical regions, following the TransCom-3 protocol, using boundary layer CO2 data from a subset of GLOBALVIEW surface sites. Global annual net BS + BB + OC CO2 fluxes over 2004–2006 for ...

Sources of carbonaceous aerosol in the Amazon basin
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Gilardoni S.; Vignati E.; Marmer E.; et al. - Copernicus GmbH, 2011The quantification of sources of carbonaceous aerosol is important to understand their atmospheric concentrations and regulating processes and to study possible effects on climate and air quality, in addition to develop mitigation strategies.
In the framework of the European Integrated Project on Aerosol Cloud Climate Interactions (EUCAARI) fine (Dp < 2.5 μm) and coarse (2.5 μm < Dp <10 μm) aerosol particles were sampled from February to June (wet season) and from August to September (dry season) 2008 in the central Amazon basin. The mass of fine particles averaged 2.4 μg m−3 duri ...

Long-term analysis of carbon dioxide and methane column-averaged mole fractions retrieved from SCIAMACHY
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Schneising O.; Buchwitz M.; Reuter M.; et al. - Copernicus GmbH, 2011Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic greenhouse gases contributing to global climate change. SCIAMACHY onboard ENVISAT (launch 2002) was the first and is now with TANSO onboard GOSAT (launch 2009) one of only two satellite instruments currently in space whose measurements are sensitive to CO2 and CH4 concentration changes in the lowest atmospheric layers where the variability due to sources and sinks is largest.

Atmospheric emissions from vegetation fires in Portugal (1990–2008): estimates, uncertainty analysis, and sensitivity analysis
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Rosa I.M.D.; Pereira J.M.C.; Tarantola S. - Copernicus GmbH, 2011Atmospheric emissions from wildfires in Portugal were estimated yearly over the period 1990–2008 using Landsat-based burnt area maps and land cover maps, national forest inventory data, biometric models, and literature review data. Emissions were calculated as the product of area burnt, biomass loading per unit area, combustion factor, and emission factor, using land cover specific values for all variables. Uncertainty associated with each input variable was quantified with a probability density function or a standard deviation value. Uncertainty and sensitivity analysis of estimates were perf ...

Beyond ‘dangerous’ climate change: emission scenarios for a new world
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, Vol. 369. N° 1934. Anderson Kevin; Bows Alice - The Royal Society, 2011The Copenhagen Accord reiterates the international community’s commitment to ‘hold the increase in global temperature below 2 degrees Celsius’. Yet its preferred focus on global emission peak dates and longer-term reduction targets, without recourse to cumulative emission budgets, belies seriously the scale and scope of mitigation necessary to meet such a commitment. Moreover, the pivotal importance of emissions from non-Annex 1 nations in shaping available space for Annex 1 emission pathways received, and continues to receive, little attention. Building on previous studies, this paper uses a ...

Cumulative carbon emissions, emissions floors and short-term rates of warming: implications for policy
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, Vol. 369. N° 1934. Bowerman Niel H.A.; Frame David J.; Huntingford Chris; et al. - The Royal Society, 2011A number of recent studies have found a strong link between peak human-induced global warming and cumulative carbon emissions from the start of the industrial revolution, while the link to emissions over shorter periods or in the years 2020 or 2050 is generally weaker. However, cumulative targets appear to conflict with the concept of a ‘floor’ in emissions caused by sectors such as food production. Here, we show that the introduction of emissions floors does not reduce the importance of cumulative emissions, but may make some warming targets unachievable. For pathways that give a most likely ...
