The effects in the following years/decades will increase in terms of weather anomalies as we descend into the Grand Solar and Geomagnetic Excursion cycle eventually resulting in a cooling of our planet. No one can know how quickly this will occur, but we do know based upon cyclic history it will occur. The Grand cycle of 200 - 400 years is forecasted to onset between solar cycle 25 and onward. Nobody can tell how quickly Geomagnetic Excursion will occur. However we do know it is accelerating with each passing year, further diminishing our magnetosphere and enabling an influx of cosmic energy.

2019/2020 is the beginning of the convergence of two larger cycles in our cyclic universe. One can then begin to forecast how rapidly the effects above will trickle down below. One can look at the Southern Hemisphere to see just how much they have been impacted. An increase in cold/precipitation has significantly impacted the Southern Hemisphere lower latitude regions. Here's the data factoring into the current 2019/2020 Northern Hemisphere equation that we do know.

Low solar activity + space weather particle forcing increase + 3 major 2019 stratospheric eruptions = 2019/2020 Winter is coming.

No one has a crystal ball to peer into the future. The best we can do is observe and analyze the data moving forward.
