He posts: Solar modulation of galactic cosmic ray flux on the wane? Something extraordinary is happening. Coronal holes rarely made the news during Solar Cycle 23. Solar Cycle 24, however, is a different story.
Coronal holes are the source of high speed solar winds. It is widely known that there is an inverse relationship between the solar wind and galactic cosmic rays (GCRs). A strong solar wind normally results in a drop in the GCR flux. The "something extraordinary" referred to in the title of this article is that for the last several days this inverse relationship has gone missing.

Since last Saturday, May 5, 2018 it has been generating a solar wind well in excess of 600 km/s and as high as 700 km/s. Normally, in the face of such a strong solar wind, GCRs would show a significant drop of around two percent. It has not happened. In fact, GCR’s are actually climbing. Below are two charts.
The first chart is the GCR chart from Oulu Cosmic Ray Station for the past 30 days.
The second is the yearly chart dating back to 1965 when observations began:
The +5% line represents a GCR count of 6472. The +10% line is 6780. All during these past several days, GCRs have remained at or near their peak for this solar minimum, which is around 6700. Normally, when a solar wind like this one hits earth there is a immediate drop in the range of two percent or down to around 6500, and a recovery time measured in days. It just didn’t happen this time, and Mr De Haven says he has never seen anything like this.
Were this to continue, things could get interesting. GCRs are clearly related to the extreme rain happening all over the world, and many of us "casual observers" as well as number of mainstream scientists think they are also closely related to an increase in lightning, seismic and volcanic activity, and even tornadoes. Something extraordinary may indeed be happening.
