Seems NOAA reject data that doesn't fit with IPCC predictions.

Yesterday NOAA announced with much fanfare that:

The world's ocean surface temperature was the warmest for any August on record, and the warmest
on record averaged for any June-August (Northern Hemisphere summer/Southern Hemisphere winter)
season according to NOAA's National Climatic Data Center in Asheville, N.C. The preliminary
analysis is based on records dating back to 1880.

Besides the UAH data for August I cited, Bob Tisdale shows that some other datasets don't agree
with NOAA's conclusion. - Anthony

Record Sea Surface Temperatures Are Only In NOAA ERSST.v3b Dataset
Guest post by Bob Tisdale

The NOAA press release claims the August Global Sea Surface Temperature (SST) was the warmest on
record

[see rest with graphs at link]

But the satellite data was removed because it was felt the satellite data caused a downward bias.
Reynolds, Smith, and Liu write in a November 14, 2008 attachment to their main ERSST.v3b webpage,
"In the ERSST version 3 on this web page WE HAVE REMOVED SATELLITE DATA from ERSST and the merged
product. The addition of satellite data caused problems for many of our users. Although, the
satellite data were corrected with respect to the in situ data as described in reprint, there was a
residual cold bias that remained as shown in Figure 4 there. The bias was strongest in the middle
and high latitude Southern Hemisphere where in situ data are sparse. THE RESIDUAL BIAS LED TO A
MODEST DECREASE IN THE GLOBAL WARMING TREND AND MODIFIED GLOBAL ANNUAL TEMPERATURE RANKINGS."

CLOSING

It appears that the methods used by NOAA to calculate Global SST in their ERSST.v3b dataset and the
removal of the satellite data from those calculations created an upward bias
