Here is some NOAA sources
Readers here know that I have very little respect for NOAA. They seems to take the most absurd positions at the most clear cut times.
NOAA is fully pushing the Global Warming non-sense, while at the same time, and this is their current Fiasco....pretending that solar cycle 24 may last 14 years.
Usually solar cycles are 11 years with some variance but not much. The standard deviation is 1.202,
They haven't concluded that Solar Cycle 24 is over yet and think it extends out 2 more years.
The last cycle, SC23, was deemed 12.3 years, so if SC24 turns out to be 14 years, then the complete
2-cycle-cycle would be 26.2 years.
That would be a data record since 1761
NOAA is predicting something that we have never seen before. How likely is that?
The histogram of the Full Cycle (2 half cycles) is even more interesting
but I think a histogram of the data presents an interesting view.
