I'm not so sure we can say that yet. Could be we might not know until winter 2021-22. There were certainly some instances of a delay...Even with the last solar minimum. We hit bottom in late 2008. But obviously, we didn't see the effect until a year later! And I'm wondering if, on the record, the bottom of the minimum only just happened this year? (in which case, not seeing a result this winter would make more sense)
Now, could the solar minimum no longer matter because of a changing climate? Sure. But if the historical "delay" is true...maybe we should wait longer.
