Guest essay by David Archibald One of the most accurate ways of predicting the amplitude of the next solar cycle is to derive it from the strength of the solar polar fields at solar minimum. And you don’t have to wait for solar minimum. An accurate assessment can be made four years before minimum, which…

The Bray (Hallstatt) Cycle

Guest essay by Andy May and Javier The evidence for a persistent irregular climate cycle with a period of 2400 ±200 years is strong. There is compelling evidence of a solar cycle of about the same length and phase; suggesting that the solar cycle might be causing the climate cycle. We will present a summary…

Solar Cycle Update November 2016

Guest essay by David Archibald Solar cycle length is one of the more important parameters, though difficult to judge even though the cycle is more than half over. The longer Solar Cycle 24, the colder the climate will be during Solar Cycle 25 according to Friis-Christensen and Lassen theory. The one true indication of the…
