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 …

Referred to by letter-number combinations such as A1, A2, B1, and B2, each scenario was based on a complex relationship between the socioeconomic forces driving greenhouse gas and aerosol emissions and the levels to which those emissions would climb during the 21st century.

The SRES scenarios are divided into four families, or storylines, that describe distinctly different future developments of economic growth, global population and technological change. These four families are known as ‘A1’, ‘A2’, ‘B1’ and ‘B2’. Some IPCC studies have been able to foresee four possible future scenarios (A1, A2, B1, B2), by taking into consideration population growth, economic development, available resources (meaning primary energy sources) and technology. These hypothetical evolutions are called “scenario families”.

The IPCC scenarios are based on a data-driven storyline (or narrative) of what events have occurred in the past and how the future may unfold. There are four commonly used scenario families.
