Cambridge University Press, UK. pp 570 Available from Cambridge University Press , The Edinburgh Building Shaftesbury Road, Cambridge CB2 2RU ENGLAND Der IPCC-Bericht von 2001 ("Third Assessment Report") basiert auf nahezu 40 Szenarien, die je nach Annahme über die weitere Entwicklung der menschlichen Weltgesellschaft in vier "Familien" (A1, B1; A2, B2; vgl. die nebenstehende Grafik) gegliedert sind. These make up four storylines: A1, A2, B1, and B2. The following image illustrates the grid we will use to summarize the assumptions and parameters. Each storyline projects numbers for fertility, mortality, and migration rates from 2010 through 2100, drawn from US Census Bureau data and projections. The Country-Level GDP and Downscaled Projections Based on the Special Report on Emissions Scenarios (SRES) A1, A2, B1, and B2 marker scenarios, 1990-2100, were developed using the 1990 base year GDP (Gross Domestic Product) from national accounts database available from the UN Statistics Division.

2009-04-01 · While the A1F1 scenario and the A2 scenario can accurately be assigned to the classes of non-intervention scenarios (pessimistic scenarios or current trends scenarios), the B1 and B2 scenarios fit best to the group of scenarios that need interventions or even a “great transition” towards sustainable development (Raskin et al., 2005), which is strongly interlinked with climate policy (IPCC Figure 5-7: Standardized global N 2 O emissions for SRES scenarios, classified into four scenario families (each denoted by a different color code - A1, red; A2, brown; B1, green; B2, blue). Marker scenarios are shown with thick lines without ticks, globally harmonized scenarios with thin lines, and non-harmonized scenarios with thin, dotted lines (see Table 4-3 ). A2 and B2 were the main scenarios used in the IPCC Third Assesment Report (TAR, 2001) and later A1B has been the most common scenario. 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 This collection contains datasets based on Intergovernmental Panel on Climate Change (IPCC) Assessment Reports and IPCC Special Reports. The IPCC SRES emissions scenarios (A1, A2, B1, B2) used population projections from both the United Nations (UN) and the International Institute for Applied Systems Analysis (IIASA). A2, B1, and B2, plus three groups within the A1 scenario family, A1B, A1FI, and A1T – and four cumulati ve emissions categories were developed as the smallest subsets of SRES 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 A1 family is further subdivided into three groups (A1FI, A1T and A1B), so there are in total six scenario groups, for which so-called ‘illustrative’ emissions scenarios were developed by IPCC Working Group III in 2000. Each colored emission band shows the range of harmonized and non-harmonized scenarios within each group. For each of the six scenario groups an illustrative scenario is provided, including the four illustrative marker scenarios (A1, A2, B1, B2, solid lines) and two illustrative scenarios … The set of scenarios consists of six scenario groups drawn from the four families: one group each in A2, B1, B2, and three groups within the A1 family, characterizing alternative developments of energy technologies: A1FI (fossil fuel intensive), A1B (balanced), and A1T (predominantly non-fossil fuel).

SRES-scenarier kan betraktas som ”familjer” med huvudsakliga beteckningarna A1, A2, B1 och B2. I SMHIs beräkningar ingår huvudsakligen SRES A1B, eftersom det användes mest i det stora internationella projektet ENSEMBLES, som SMHI deltog i.

Instead, a scenario is a possible future based on a given set of assumptions based on energy use, emissions, land use and general climate system behavior.
