The handwriting for a Super-Grand Solar Minimum is on the wall
Lloyd Martin Hendaye
Alas and well, the handwriting for a 90-year Super-Grand Solar Minimum c. AD 2020 – 2110 is on the wall.
In 2005, Danish researcher Henrik Svensmark correlated 11-year sunspot cycles with Sol’s far-reaching “solar wind” whose streaming plasma sheath varies in intensity with solar radiation. Connecting this plasma barrier with cosmic-ray penetration of Earth’s atmosphere, from 2015 Russia’s Valentina Zharkova proposed that energetic galactic particles seeded Earth’s global cloud-cover, producing heavy overcast that dropped temperatures by blocking total solar irradiance (TSI).
Of course, this process dates from the formation of Earth’s solar system… yet Gaia suffered no global Ice Ages from pre-Cambrian Ediacaran eras to the mid-Pliocene, well over 1.50 billion years. What’s different now is continental landmasses’ plate-tectonic dispositions: From mountain-building planetary orogenies in the mid-Oligocene some 45 million YBP, conjoined North and South American continents have walled off Eastern from Western hemispheres, stalling global atmospheric-oceanic circulations patterns.
However this occurs, for some 3.6 million years resulting “climate cells” have induced cyclical Pliocene-Pleistocene Ice Ages lasting an average 102 kiloyears, interspersed with median 12,250-year interstadial remissions such as the recent Holocene Interglacial Epoch, which began c. 14,400 YBP and ended 12,250 + 3.500 – 14,400 = AD 1350, coincident with Kamchatka’s strato-volcano Kambalny Eruption, a 70-year Grand Solar Minimum similar to that of 1645 – 1715, and a 500-year Little Ice Age through AD 1850/1890.
In geophysical context, these long-term climate cycles have no anthropogenic CO2 component whatsoever, a fact confirmed by Australian Robert Holmes’ December 2017 “Mean Molar Mass version of the Ideal Gas Law”, where global atmospheric surface temperature GAST = PM/Rp (qv). Following Earth’s 140-year “amplitude compression” rebound from the Little Ice Age (LIA) –where succeeding warm-cool phases occurred 1890 – 1939; 1940 – 1979; 1980 – 2009; and 2010 – 2029– Millennials and subsequent generations are shortly due for rude comeuppance.
Already some 670 years into a Pleistocene Ice Age due to cover 60 – 70% of Earth’s habitable landmasses with ice-sheets two miles thick, transhuman populations will either remove en masse off-Earth to intrasolar refugia or face civilizational extinction. In brief: Changes due through AD 2125+ will outweigh everything from AD 1600 by orders of magnitude, as inconceivable to present-day prognosticators as aircraft, radio and television, nuclear power, DNA and info-tech would be to Max Planck in 1900.
