Recent claims by Donald Trump suggest the IPCC admitted that the RCP8.5 climate scenario was wrong. However, RCP8.5 was never a prediction, but a high-emissions scenario used by scientists to model potential climate outcomes based on radiative forcing. While newer emissions scenarios are being developed for future IPCC reports, the world remains on track for significant warming. The transition to new models does not negate the risks of climate change or the necessity of decarbonization to avoid catastrophic temperature rises.
