Can you provide a link to the NOAA data that you allege contradicts the rather straightforward bits that I posted?

The IPCC never projected present GMST to be "5 degrees higher" than what is observed. The IPCC's SLR projections have routinely been characterized by many in the scientific community as being conservative, largely (if I remember correctly) due to ice sheet consideration.
