¥Warming will increase if GHG
increase.If GHG were kept
fixed at current levels, a committed 0.6¡C of further warming would be
expected by 2100.More
warming would accompany more emission.
1.8oC = 3.2oF
2.8oC = 5.0oF

B1 and A1B have
similar population projections – ca 7 billion at 2100. A2 population
more than double at 15 billion. GDP/capita is 47k$, 75k$, 16k$ for B1, A1B,
A2.
