RCP2.6: Increase in radiative forcing to 2.6 W/m2 by roughly 2050, then no change or even a slight decline through 2100
- Implies strong changes in energy usage and public policy leading to a decrease in greenhouse gas emissions
RCP4 and RCP6: Increase in radiative forcing to 4 and 6 W/m2, respectively, by 2100. A general plateau occurs for each scenario.
- Implies some changes that will curtail some greenhouse gas emissions while others remain on the rise
RCP8.5: A steady, unabated increase to 8.5 W/m2 by 2100 with no plateau in sight.
- incorporate the summary table here
- Implies little/no change and a large increase in greenhouse gas emissions leading to a severe spike in the overall temperature of the Earth
