The IPCC Sixth report did not estimate the likelihoods of the scenarios&#x3A;&#x200A;SPM-12&#x200A; but a 2020 commentary described SSP5–8.5 as highly unlikely, SSP3–7.0 as unlikely, and SSP2–4.5 as likely.

However, a report citing the above commentary shows that RCP8.5 is the best match to the cumulative emissions from 2005 to 2020.
