Temperature index change (with the base period 1951-1980) since 1950 at seasonal resolution, for the globe (upper line) and for low latitudes (lower line). [This is an update of Figure 7 in Hansen et al. (1999).] Green triangles mark large volcanic eruptions. SST at Nino 3.4 is the 12-month running mean.
