El aumento de CO2 en la atmósfera de 2013 a 2014 fue similar al promedio de los últimos 10 años. En cambio, el aumento tanto del CH4 como del N2O de 2013 a 2014 fue superior al observado de 2012 a 2013 y a la tasa media de aumento de los últimos 10 años. El índice anual de gases de efecto invernadero de la Administración Nacional del Océano y de la Atmósfera (NOAA) de Estados Unidos de América muestra que entre 1990 y 2014 el forzamiento radiativo causado por los GEI de larga duración aumentó un 36%, al que el CO2 contribuyó casi en un 80%.

Tant pour le CH4 que pour le N2O, la hausse relevée entre 2013 et 2014 est supérieure à celle constatée entre 2012 et 2013 et au taux moyen de progression de ces dix dernières années. Selon l’indice annuel d’accumulation des gaz à effet de serre dans l’atmosphère (AGGI) publié par l’Administration américaine pour les océans et l’atmosphère (NOAA), le forçage radiatif de l’atmosphère induit par les gaz à effet de serre persistants s’est accru de 36 % entre 1990 et 2014, le dioxyde de carbone étant à l’origine d’environ 80 % de cette augmentation.

National Greenhouse Gas Emissions Baseline Scenarios : Learning from Experiences in Developing Countries
Xenarios Stefanos - RiceClima, 2013This report aims rather to contribute to a better understanding of the issues and challenges involved in drawing up baseline scenarios, by documenting and drawing lessons from the breadth of existing practices in a range of countries. This existing diversity is both a key asset for gradually increasing the robustness of baseline scenarios, but also the reason for a lack of comparability.

66 - February 2012 - A method for estimating the sea-air CO2 flux in the Pacific Ocean
is an issue of 気象研究所技術報告. Meteorological Research Institute, 2012In this technical report, we describe a newly developed method for evaluating monthly fields of oceanic pCO2 and the subsequent temporal variations of the sea-air CO2 flux over extensive regions of the North and South Pacific by using synthesized observational data. The application of this method is expected to contribute to understanding of future changes in the ocean carbon sink and the ocean's role in controlling the rate of atmospheric CO2 increase.

Multi-model climate change projections for India under representative concentration pathways: In Current Science, vol.103, issue 7 (10/10/2012)
Climate projections for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) are made using the newly developed representative concentration pathways (RCPs) under the Coupled Model Inter-comparison Project 5 (CMIP5). This article provides multi-model and multi-scenario temperature and precipitation projections for India for the period 1860–2099 based on the new climate data. We find that CMIP5 ensemble mean climate is closer to observed climate than any individual model. The key findings of this study are: (i) under the business-asusual (between RCP6.0 and RCP8.5 ...

Fluorinated greenhouse gases 2011 : Aggregated data reported by companies on the production, import and export of fluorinated greenhouse gases in the European Union — Summary
EEA, 2012Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (the so called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases typically have very long lifetimes in the atmosphere and high global warming potentials (GWPs).
The European Union Regulation (EC) No 842/2006 on certain fluorinated greenhouse gases (the 'F-Gas Regulation') introduced a requirement for each producer, importer and exporter of more than one tonne of F-gases to report to the European Commission ...

Carbon sequestration in agricultural soils
World Bank, 2012The purpose of this report is to improve the knowledge base for facilitating investments in land management technologies that sequester soil organic carbon. While there are many studies on soil carbon sequestration, there is no single unifying volume that synthesizes knowledge on the impact of different land management practices on soil carbon sequestration rates across the world. A meta-analysis was carried out to provide soil carbon sequestration rates in Africa, Asia, and Latin America. This is one important element in decision-making for sustainable agricultural intensification, agro-ecosy ...

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 ...

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 ...
