FIGURE 13. Global (land plus ocean) and global land and ocean
surface temperatures relative to the 1951-1980 mean. The
land-plus-ocean and land only graph are noisy because of weather
variability. The bottom diagram is the Nino 3.4 index for tropical
Pacific Ocean temperature. (Top and middle figures data from
GISS Temperature pages.)
Bottom figure data from
NOAA Climate Prediction Center.)
