Figure 3

(a) The January climatology of downward shortwave radiation at the surface from the 21st century run with GFDL CM2.0, based on 2080–2100 average. (b) The same as (a) but from the 20th century run, based on 1980–2000 average. (c) The trend, defined as (a) minus (b). The color scales with units in W/m2 are shown on the right.
