for RFC2 would have transitioned to a high risk at 1.5℃ and RFC1 would be well into the transition to very high risk . Remaining below 2ºC warming  would imply that risk for RFC3 through 5 would be transitioning to high, and risk for RFC1 and RFC2 would be transitioning to very high . By 2.5°C warming, RFC1 will be in very high risk  and all other RFCs will have begun their transitions to very high risk . These highest levels of risk are associated with an irreversible component, such that some impacts would persist even were global temperatures to subsequently decline in an 'overshooting' scenario.
