You re curious eh Well I m not so adverse either being curious about the nature of certain edit patterns But in the regards to the matter more immediately at hand the referenced IPCC document Summary for Policymakers is frankly not a very well written summary for its intended um not so aware audience It makes all sorts of refs to particular time periods like 1980 1999 the reference period 2020 2029 and 2090 2099 but in terms of projection it does very clearly single out 2100 as in the graph SPM 5 on page 14 and especially in this highlighted summary box on page 12 PROJECTIONS OF FUTURE CHANGES IN CLIMATE A major advance of this assessment of climate change projections compared with the TAR is the large number of simulations available from a broader range of models Taken together with additional information from observations these provide a quantitative basis for estimating likelihoods for many aspects of future climate change Model simulations cover a range of possible futures including idealised emission or concentration assumptions These include 14 SRES illustrative marker scenarios for the 2000 2100 period and model experiments with greenhouse gases and aerosol concentrations held constant after year 2000 or 2100 By the way you never answered my last question about moving Solar Variation BC aka
