Så IPCC använder 40 scenarier som visar mycket olika världar. Teknologisk förändring är mindre snabb men mer mångsidig än i A1- och B1-scenarierna.

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.

Illustrative scenario: A scenario that is illustrative for each of the six scenario groups reflected in the Summary for Policymakers of Nakicenovic and Swart (2000).

Cambridge University Press, UK. pp 570 Available from Cambridge University Press , The Edinburgh Building Shaftesbury Road, Cambridge CB2 2RU ENGLAND SRES limits the possible scenario outcomes by establishing four broad scenario families (A1, A2, B1, B2), which correspond to possible future world situations. These scenarios each come with a corresponding narrative storyline to describe global social, economic, technological, environmental, and … 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 2012-05-23 2020-01-04 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.

In 1996, after A1 and B1 scenarios are in the lower range of population growth, higher range of The A2 storyline and scenario family describes a very heterogeneous world. . CERA project information for IPCC Data Distribution Centre : Third A set of four scenario families (A1, A2, B1, B2) have been developed that each of this Table 10 shows the comparison results of three IPCC scenarios (i.e. A1, B1 and B2) with respect to the A2 (BAU) storyline.

These four families are known as 'A1', 'A2', 'B1' and 'B2'. The A1 family is further subdivided into three groups (A1FI, A1T and A1B), so there are in total six SRES Reference Scenarios.
