Thrust Reversal or Reacceleration? Comparison of an emissions scenario compatible with the 2 °C objective (RCP3-PD, blue) and a more-business-than-usual scenario (RCP8.5, red). (A) Respective fossil CO2 release. Note that the annual CO2 emissions drop to −3.4 Gt by 2100 in the strong mitigation case. (B) Resulting likelihood fans for global mean temperature rise.
