CONCLUSIONS

1. Collective proof that the Sun (not CO2) controls climate: A) solar output & global temperature (Graphs 1-3) have "very similar ... ‘hockey-stick’ shape” (Usoskin et al. 2005) and B) their highest/lowest peaks correspond (circles in Graphs 2, 3; NB time-lag due to ‘ocean memory’ [Higgs 2020]) C) CO2 ‘handle’ has reverse slope (Graph 4).

2. The IPCC (2013) says CO2 controls Earth’s climate and the Sun is irrelevant. This monumental blunder is costing western economies $$trillions in needless efforts to reduce harmless (beneficial) CO2.
