Fig. 7 shows the percentage change
in total crop biomass between the baseline (1961–2010) and the
future climate (2030, 2060, and 2090) for each crop and location.
Even though there is a large variation in total crop biomass across
crops and locations, the overall change in median biomass values
of 18 GCMs is negative in all future climates relative to baseline,
with smaller decreases projected for the 2030 and 2060 compared
to 2090.
