LoiczView’s ‘best prediction’ for potential vegetation was used to project
‘current’ vegetation distributions fifty years into the future under conditions
of global climate change. Current climatic data were replaced with
two, projected climate scenarios produced by a GCM created at the Hadley
Centre; one set a conservative scenario for projected climate assumed a
0.5% / annum CO2 increase and incorporated the negative forcing from
sulfate aerosols, and the other set a less conservative or more extreme
scenario for projected climate assumed a 1.0% / annum CO2 increase
and did not incorporate the negative forcing from sulfate aerosols.
