The SRES B1 Emissions Scenarios. Key Assumptions . A convergent world with the same global population as in the A1 storyline but with rapid changes in economic structures toward a service and information economy, with reductions in materials intensity, and the introduction of clean and resource-efficient technologies.

Questi modelli sono chiamati GCM (General Circulation Models, modellini circolazione generale). Alcuni studi dell’IPCC hanno individuato quattro possibili scenari futuri (A1, A2, B1, B2), considerando la crescita demografica, lo sviluppo economico, le risorse disponibili Name IPCC_ECHAM4OPYC_SRES_B2_MM Project IPCC-DDC_TAR (IPCC Data Distribution Centre : Third Assessment Report data sets) Summary The SRES data sets were published by the IPCC in 2000 and classified into four different scenario families (A1, A2, B1, B2). The B2 storyline and scenario family describes a world in which the emphasis is on local solutions to economic, social and environmental sustainability. It is a world with continuously increasing global population, at a rate lower than A2, intermediate levels of economic development, and less rapid and more diverse technological change than in the B1 and A1 storylines. IPCC-DDC_TAR (IPCC Data Distribution Centre : Third Assessment Report data sets)Summary The SRES data sets were published by the IPCC in 2000 and classified into four different scenario families (A1, A2, B1, B2). SRES_B2 storyline describes a world in which the emphasis is on local solutions to economic, social and enviromental sustainability. The RCPs cover a wider range than the scenarios from the Special Report on Emissions Scenarios (SRES) used in previous assessments, as they also represent scenarios with climate policy. In terms of overall forcing, RCP8.5 is broadly comparable to the SRES A2/A1FI scenario, RCP6.0 to B2 and RCP4.5 to B1. FN har opstillet fire hovedscenarier er A1, A2, B1 og B2, der tilsammen giver et billede af de mulige udviklingsforløb.

The B1 and B2 scenarios assumed more sustainable practices ('utopia'), with more global-focus and regional-focus, respectively. Let us now directly compare the various SRES scenarios both in terms of their annual rates of carbon emissions, measured in gigatons (Gt) of carbon (1Gt = 10 12 tons), and the resulting trajectories of atmospheric CO 2 concentrations.

These hypothetical evolutions are called “scenario families”. Medium-high emissions are attained in most of the A1 group scenarios (including the A1B marker, A1B-AIM), but also in scenarios from the B2 scenario family with high fossil-fuel use (e.g., B2-ASF). For A1 and B1 scenarios, regional population trajectories are (almost for all years) within the proposed 5% interval of their respective marker scenarios, except for two of the scenarios 18.

For A1 and B1 scenarios, regional population trajectories are (almost for all years) within the proposed 5% interval of their respective marker scenarios, except for two of the scenarios 18. 4.4.3.2. A2 Scenarios. For the A2 scenario family, future population levels are based on the high scenario (15 billion) reported in Lutz (1996) 19 Emissions Scenarios Report IPCC, 2000 – Nebojsa Nakicenovic and Rob Swart (Eds.) Cambridge University Press, UK. pp 570 Available from Cambridge University Press , The Edinburgh Building Shaftesbury Road, Cambridge CB2 2RU ENGLAND Population growth is highest in A2 (15 billion people in 2100), followed by B2 (10 billion) and A1 and B1 (7 billion). Economic growth is most rapid in the A1 scenario, followed by B1, B2 and A2. All four scenarios assume that developing countries grow faster than developed ones; the gap between rich and poor closes most rapidly in the A1 The SRES scenarios are named by family (A1, A2, B1, and B2), where each family is designed around a set of consistent assumptions: for example, a world that is more integrated or more divided.

A1FI is the most extreme scenario regarding emission rate. The A1 storyline and scenario family describes a future world of very rapid economic growth, global population that peaks in mid-century and declines thereafter, and the rapid introduction of new and The B2 scenario, in thick plain green, goes with a temperature increase of 1,5 to 2,5°C depending on the models (1 °C between the extremes). The bar named “all IS92” on the right represents the bracket of temperature increase predictions that were part of the IPCC 1996 report, all scenarios … Panel on Climate Change (IPCC) were done to investigate the direct and indirect climate impacts of the anthropogenic sulfate and carbonaceous aerosols in the future projections of climate change. The numerical simulations are carried out for all four illustrative “marker” scenarios of A1, A2, B1, and B2. The B1 and B2 scenarios assumed more sustainable practices ('utopia'), with more global-focus and regional-focus, respectively. Let us now directly compare the various SRES scenarios both in terms of their annual rates of carbon emissions, measured in gigatons (Gt) of carbon (1Gt = 10 12 tons), and the resulting trajectories of atmospheric CO 2 concentrations.

They are grouped by shaded areas for the scenario families A1B, A2, B1, and B2 with respective markers shown as lines. In addition, the four scenario groups within the A1 family A1B, A1C, A1G, and A1T, which explore different technological developments in the energy systems, are shaded individually.

Four qualitative storylines yield four sets of scenarios called “families”: A1, A2, B1 , and B2. Altogether 40 SRES scenarios have been developed by six modeling
