Annual global mean precipitation from 1940 - 2080

The black lines in the image below show the mean precipitation averaged over the entire globe for each year. Each black line represent one of the runs 32 - 62. The red line is the mean of the 31 runs together. The blue line shows the observed (estimated) annual global mean precipitation from 1979-2002 with an offset added of 0.5 mm/day (source Global Precipitation Climatology Project).

During the actual simulations the black and the red lines in the image showed the situation at at most 1 hour ago.
