Solar Cycle Warnings

For reasons including "pure politically correct", NASA has fought a losing battle - against reality - on the subject of Global Warming, which it feels obliged to believe in as a "scientifically correct" theory.

Interesting article.

The important note here was the solar superminimum when all the beat periods of the solar cycle converged on a minimum giving 3 years of a very small blank sun. Small in this case because the number of granules is a fixed quantity, and the presence of sunspots causes the photosphere to expand in order to fit the granules in (with solar output increasing according to size of disc + radiation from the sunspots themselves.

One other item of note was the change due to heating of the oceans from the monsoonal climate mode#2 during the superminimum, to climate mode#3 (oceanically moderated) since April 2012. Climate mode#3 is much more efficient @ cooling the planet (~2 deg C per CO2 level) then climate mode#2. The result is that the solar cycle output may predict a climate mode change, back to the less efficient climate mode#2 caused by the increased cooling ability of mode#3 and the drop in solar output from the 1st peak of a likely double peaked solar max.

As can be guessed, the switch between the 2 modes is driven by the temperature of the ocean, rather than the continent.

Historical event add ons were interesting but in those cases changes in sunspot frequency had nothing to do with the historical events. The bulk ocean was colder in 1906, so no climate mode flip flops took place @ that time.

Climate mode#3 incidentally first appeared in the late 1990s as a flash change lasting a few months or so in a year, and increasingly common during solar max years as the ocean continued to warm.

Climate mode#3 has only previously appeared in the Holocene as a result of transfer of heat from ocean to atmosphere in times of sudden global cooling due to dust pall (535AD when 2 small asteroids punched holes in the gulf of Carpentaria, N. Australia {dark ages}), and during SO2 aerosol hazes from very large volcanic eruptions such as the 1815 tambora eruption (@ its 1815-16 aftermath). The reason it triggers then is due to its more efficient transfer of heat from ocean to cooled polar regions under the dust pall or high albedo aerosol.
