You mean that IPCC predictions based on climate models have been replaced by different predictions based on newer models as more data became available over time?

Unfortunately (for us) it does look like newer predictions predict worse outcomes with higher confidence [1].

PS: yes scientific consensus changes over time as a function of available measurement data and understanding. That's not a sign of failure but of improved scientific insight.
