En-en adult card 15 radiative forcing: Difference between revisions

The secondary graph represents the radiative forcing over two and a half centuries (history and projections). In the 5th IPCC report, the radiative forcing is 2.3 W/m². The values of the forcing in 2100 gave their name to the IPCC scenarios (RCP 2.6, RCP 4.5 etc.). The colours of these scenarios can be found in the graphs of maps n°5, 11, 15, 21, 22 and 24.

For more details on this graph, see the fact sheet on PCR scenarios.

RCP is an acronym for [[wikipedia:Shared_Socioeconomic_Pathways|'''S'''hared '''S'''ocioeconomic '''P'''athways]] as introduced in the 6th Assessment Report by Working Group 1 of the IPCC<ref name=":0">Definition of Shared Socio-economic Pathways, full report 6, working group 1, [https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_Full_Report_smaller.pdf p1-100]</ref>. These are the different scenarios proposed by the IPCC. SSPs are “pathways” that examine how global society, demographics and economics might change over the next century. The new SSPs offer five pathways that the world could take. The SSPs’ quantitative projections of 15 socio-economic drivers include population, gross domestic product (GDP) and urbanization<ref name=":0" />. Compared to previous scenarios, these offer a broader view of a “business as usual” world without future climate policy, with global warming in 2100 ranging from a low of 3.1°C to a high of 5.1°C above pre-industrial levels.
