    The predicted sunspots for the years 2018 and 2019 look interesting, especially that string of zeroes in the low column. Please correct me if I'm mistaken, but wasn't the last time this happened during the "Little Ice Age", or Maunder Minimum?

    It will be interesting to see if space weather has any important effect on Earth weather, especially so if we are taxed to fight both global warming and global cooling at the same time. :rolleyes:

    The current trend may be more like the Dalton minimum. Svalgaard and others are working to improve understanding of the previous trends in sunspot numbers (SSN).
