The trouble is, "skeptics" only believe Roy Spencer's chart

RealClimate: Global temperature 2013

Real Climate notes at the link above:

The global temperature data for 2013 are now published. 2010 and 2005
remain the warmest years since records began in the 19th Century. 1998
ranks third in two records, and in the analysis of Cowtan & Way,
which interpolates the data-poor region in the Arctic with a better
method, 2013 is warmer than 1998 (even though 1998 was a record El Nino
year, and 2013 was neutral)....

In all four data series of the global near-surface air temperature, the linear trend even from the extreme El Niño year 1998 is positive, i.e. shows continued warming, despite the choice of a warm outlier as the initial year.

In all four data series of the global near-surface air temperature, 2010 was the warmest year on record, followed by 2005.

 

The year 1998 is, at best, rank 3 – in the currently best data set of Cowtan & Way, 1998 is actually only ranked 7th. Even 2013 is – without El Niño – warmer there than 1998.

 
The German news site Spiegel Online presents these facts under the headline Warming of the air paused for 16 years (my translation). The headline of the NASA news release, NASA Finds 2013 Sustained Long-Term Climate Warming trend, is thus completely turned on its head.This will not surprise anyone who has followed climate reporting of Der Spiegel in recent years. To the contrary – colleagues express their surprise publicly when a sensible article on the subject appears there. For years, Der Spiegel has acted as a gateway for dubious “climate skeptics” claims into the German media whilst trying to discredit top climate scientists (we’ve covered at least one example here).

As I say at the title to the post, the problem with this is that "skeptics" still cling to Roy Spencer's satellite temperature chart as "proving" that 1998 was the hottest year ever.

Until Spencer's figures show a peak above 1998, (likely in the next El Nino), they will not change their belief.
