RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
The Special Report on Emissions Scenarios (SRES) is a report by the Intergovernmental Panel on Climate Change (IPCC) that was published in 2000. The greenhouse gas emissions scenarios described in the Report have been used to make projections of possible future climate change.
Many parameters influence climate change scenarios. Three important parameters are the number of people (and population growth), their economic activity new technologies. Economic and energy models, such as World3 and POLES, quantify the effects of these parameters. Climate change scenarios exist at a national, regional or global scale.

By 2050, 12 major African cities would collectively sustain cumulative damages of US$65 billion for the "moderate" climate change scenario RCP4.5 and between US$86.5 billion to US$137.5 billion on average: in the worst case, these damages could effectively triple. [79]
Environmentalist Bill McKibben imagines what would happen if we "solved" climate change by 2050. Here's what the world would look like.
English: "Projected global population increase from 2010 to 2050 and the corresponding projected gaps in agricultural food production, land use, and climate mitigation. All projections are based on data reported in the World Resources Institute (2019) report. (a) The projected population increase is 3 billion people, a 43% increase.
Thanks to climate change, the number of hurricanes and typhoons rated as Category 3 storms and higher could double by the year 2050, a new study concludes.
