We summarize our experimental data on radiocarbon variations in tree rings covering the last several hundred years. Special attention was devoted to the Maunder Minimum of solar activity which is displayed in Δ14C. It is shown that the modulation of galactic cosmic rays at Wolf numbersW ≈ 0 does really exist and that the 22-yr periodicity at that period is more pronounced than the 11-yr periodicity. The properties of future theoretical models of solar activity are briefly discussed.
