NOAA revised their global surface temperature product in June 2015 to show more global warming during the post-1998 period. Those data manipulations supposedly ended the slowdown in global warming over that period.  The changes to NOAA’s global ocean surface temperature product were the primary cause of the NOAA’s hiatus-disappearing act. That dataset, NOAA’s new Extended Reconstructed Sea Surface Temperature dataset, version 4 (ERSST.v4), received a lot of media and blog attention when NOAA published Karl et al. (2015) Possible artifacts of data biases in the recent global surface warming hiatus back in June 2015.

The new NOAA ERSST.v4 sea surface temperature dataset has since been included in both the NOAA and the GISS global land+ocean surface temperature products. Because the oceans cover about 70% of Earth’s surface, the new NOAA ERSST.v4 data are a critical component. …
