Below are maps of the mean surface temperature anomaly for the past month, the past three months, and the past 12 months. Regional weather patterns, apparent on the monthly time scale, tend to disappear in averages over longer time scales. In the chart in the lower right we show the 12-month running means of the global land-ocean temperature anomalies.
Most recent one, three and 12 month mean global temperature anomaly maps, and 12-month-running mean global temperature anomaly. (Also in PDF, last modified 2014/04/12, now with GHCN version 3 and ERSST).
The figure below shows 60-month (5-year) and 132-month (11-year to minimize the effect of the solar cycle) running means of the surface temperature deviation from the 1951-1980 mean. This graph makes clear that global warming is continuing it did not stop in 1998. The year 1998 was remarkably warm relative to the underlying trend line (see updated Figure 12 of "Storms"), in association with the El Nino" of the century (updated Figure 13). But the underlying global temperature has continued to rise, despite the fact that solar irradiance for the past few years has been stuck in the deepest solar minimum in the period of satellite data (updated Figure 11).
60-month and 132-month running means of global surface temperature anomaly with a base period 1951-1980. (Also in PDF, Data through March 2014 are used for computing the means. last modified 2014/04/12, now with GHCN version 3 and ERSST).
Note 1: GHCN-M version 3 replaced version 2 in GISS temperature analysis because NOAA/NCDC no longer updates version 2. (since 2011/12/15)
Note 2: Ocean data were switched from HadISST1 + OI SST to ERSST. (since 2013/01/15)
