Solar sunspot cycle 24 just ended

The 11-year sunspot cycle number 24 has just ended. We are entering sunspot cycle 25. The number of sunspots has been decreasing over the past 3 cycles which has been about 4 decades. See plot below.

Note cycles 20 to 22, with an increase in peak sunspot number, is the same period that global warming has been claimed to be most significant . Then from cycle 22 to cycle 24 we see a decrease, but also there have been reports of global cooling, most significantly in the last decade or so.

Here I have labelled the peaks with number assigned to each sunspot cycle. On the left vertical axis is the 13-month smoothed number of sunspots. This is equivalent to yearly average. Colours indicate the fact that north and south hemisphere exhibit different numbers of sunspots. Data are available here.

Global cooling coming

You think this southern hemisphere winter is cold, according to Professor Valentina Zharkova,1 reported on Channel 9 News here in Australia, solar activity, such as sunspots, will drop up to 60 percent by 2030 and plunge the planet into a mini Ice Age.2,3 She makes the connection in her research between solar irradiance and the earth’s weather and sunspots are an indication of the cyclic activity of the sun.

In only 15 years time we should be in the middle of a mini-Ice Age. After this weekend in Adelaide, South Australia–located on the edge of the Antarctic Ocean–I am inclined to believe such a report. It has been cold!

This is the same prediction that John L. Casey made in his bookDark Winter, How the Sun Is Causing a 30-Year Cold Spell” where he predicted a period of extreme cold by the year 2030. In fact, he predicts it will last 30 years, a period similar to the “Dalton Minimum” around 1810 or even worse, the “Maunder minimum”, which lasted from 1645 to 1715.

The coming long dark winter?

Dark Winter

book long dark winterIn his book “Dark Winter, How the Sun Is Causing a 30-Year Cold Spell,”1 John L. Casey outlines a distinctively different interpretation of so-called ‘global warming.’ Casey makes the claim that, in 2007, he announced to the world, to those who would listen anyway, that the Earth would from that time on undergo a massive cooling period, which would last for about 30 years.

Casey developed his theory around what he calls solar hibernation. This is an expression to describe the state of the Sun when it exhibits a long period of low sunspot number. That is called solar minimum by the space science community.

Casey documents a theory that the Sun is absolutely the main driving force for Earth weather. Solar irradiance is the energy flux experienced at the Earth, and human kind cannot do anything about it.

There are many websites, both for and against anthropogenic global warming, now called ‘climate change’ but Casey’s theory is different. He is not the only engineer or scientist to notice a correlation between sunspot activity and global temperatures, but he adds 32 other physical reasons (lines of evidence) that corroborate his theory, in Appendix 3 titled: “Press Release: Global Warming Has Ended; the Next Climate Change Has Begun.
