For example, the comparison of the A1B and
B2 marker scenarios indicates that they have similar emissions of about 13.5 and 13.7 GtC by 2100, respectively.
For example, under the
B2 storyline, the change in the global area of grassland between 1990 and 2050 varies between -49 and +628 million ha (Mha), with the
marker scenario giving a change of +167 Mha (Naki» cenovi» c et al., 2000).
The IPCC Special Report on Emission
Scenarios (SRES) generated six marker / illustrative scenarios (labelled A1B, A1T, A1FI, A2, B1, B2) plus four preliminary marker scenarios (labelled here A1p, A2p, B1p,
