In part 2 we'll see that seasonal extreme warm anomalies in 2009 - 2011 are well above the 1951 - 1980 base period typically used in GISTEMP analyses - indicative of global warming's role in heatwaves.

It has no bearing on the record since the record for GISTEMP is 2005.

The NASA GISTEMP global temperature anomalies for March are now available.

The NASA GISTEMP record is the most detailed of the four datasets, with grid boxes two degrees longitude by two degrees latitude.

Global surface temperature relative to 1880 - 1920 based on GISTEMP analysis (mostly NOAA data sources, as described by Hansen, J., R. Ruedy, M. Sato, and K. Lo, 2010: Global surface temperature change.

Figure 2: Difference in Arctic temperature trends between GISTEMP and 3 other reconstructions on the period 1997 - 2012.

Just looked at GISTemp global profile.

The effect is illustrated in Figure 1: The first graph is from the NASA GISTEMP temperature record, while the second uses the adjusted data of Foster and Rahmstorf (2011) which removes some of the short term variations from the signal.

As explained in Part 1A and Part 1B, the 1200 km area weighting scheme used by GISTemp is based on the known and observed phenomena of Teleconnection; that climates are connected over surprisingly long distances.

The models overestimated warming from 1979 - 2011, but if you look at GISTEMP for example you can see that the East Pacific is cooler in 2011 than it was in 1979 and the models did not capture that as they have no PDO in the correct phase and are not expected to because PDOs are transient changes.

For Figure 1, global mean temperatures are plotted from the HadCRUT4 and GISTEMP products relative to a 1900 - 1940 baseline, together with global mean temperatures from 81 available simulations in the CMIP5 archive, also relative to the 1900 - 1940 baseline, where all available ensemble members are taken for each model.

You're assuming that Hansen's projections use the same baseline as the current GISTEMP dataset, which is 1951 - 1980.

You can take out data points you don't like, you can apply whatever correction factors you want (such as the one that Nasa's GISTEMP series uses to compensate for the dearth of measuring stations across the Arctic), and you can therefore end up with a temperature curve that might look a little different: but don't say it can't be done, because it can.

The currently used SCAR data are made available from the main GISTEMP site.

It is not clear whether the time series such as GISTEMP actually correct for this.

Finally, the west coast of Australia is warm, although not exceptionally so in the 250 km resolution GISTemp map.

We also applied the method to GISTEMP monthly data (the results are slightly different from Schwartz's because we used data through July 2007).

Chris O'Neill, If you think a graph of GISTEMP since 1880 is in any way empirical proof that there is a human component to the increasing global temperature then there is no point discussing further

You stated «The red line is the annual global - mean GISTEMP temperature record (though any other data set would do just as well),...

As the figure caption says, the ccc - gistemp result in the figure was produced using «software revision 700 ``.

In the following figure I took the ONI index and found the lead with the greatest correlation to the monthly GISTEMP values (2 months), regressed that out, and recalculated the annual means.

A plot of land - only unadjusted and UHI - adjusted GISTemp data would show a more discernible difference (but still not huge).

This guest post is written by Filipe Fernandes, one of our Google Summer of Code students, who is working on our ccc - gistemp project.

HadCRUT3v does not extrapolate past the coast, while GISTEMP extrapolates from the circum - Arctic stations — the former implies that the Arctic is warming at the same rate as the rest of the globe, while the latter assumes that the Arctic is warming as fast as the highest measured latitudes.

When the May figure for GISTemp comes out (presumably) next week, the «hiatus» will most likely be no more.

Aug. 15, 2017: The standard GISTEMP analysis now uses the ERSST version 5 dataset for sea surface temperatures, rather than ERRST v. 4.
