Farming very difficult during Grand Solar Minimums
Grand Solar Minimums (GSM) take 10 years for the effects of climate change (cooling) to be locked into fossil records in North America and Europe. Winters become longer, start early and finish late. Spring and Summer are much more wetter than the same seasons during a benign warm period like 1945 to 2008.
This GSM has to finish this cycle Solar Cycle 24, possibly at the end of 2020. The next cycle (SC25) may be a much reduced 11 years long, with a full sized Sun Spot count maximum of 55. Yes, fragment short-lived spots will boost the spot count by a further 100 spots per month during Solar Max, but these produce far less UV than full sized ones.
UV controls our climate by moderating the normal meridional jet stream to far more lateral streams as during the Solar Warm Period. Following this GSM is a seventy years Tepid period call a Gleissberg Period similar to 1890 to 1940.
Farming during a Grand Solar Minimum will be very difficult, particularly in our Industrial mechanised heavy farming practise, which needs the soil to be dry to work on.
This has significant implications for crop yields. History repeats itself. The Dalton GSM caused millions of deaths in Asia due to drought and crop failures. The climate effects of the Late Antique Little Ice Age (LALIA) 585AD and its following volcanism caused similar population reductions due to crop failure and disease.https://www.iceagenow.info/warmer-times-are-times-of-success-and-prosperity-for-man-kind/
Warmer times are times of success and prosperity for man-kind
According to ice core records, the last millennium 1000AD – 2000AD has been the coldest millennium of our current Holocene interglacial. This point is more fully illustrated with ice core records on a millennial basis back to the Eemian warm period 120,000 years ago, here:
Our current, warm, congenial Holocene interglacial, although cooler than the Eemian, has been the enabler of mankind’s civilisation for the last 10,000 years, spanning from mankind’s earliest farming to recent technology.
(Editor’s note: Please be aware that the Eemian Period was warmer than today. It lasted from about 128,000 years ago to 115,000 years ago, long, long before the industrial revolution began.)
Viewing the current Holocene interglacial on a century by century and on a millennial basis is realistic. But it seems that, driven by the need to continually support the Catastrophic Anthropogenic Global Warming thesis / religion Climate scientists and Climate alarmists examine the temperature record at too fine a scale, weather event by weather event, month by month, or year by year.
However, from the broader perspective, each of the notable high points in the current 11,000 year Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than the previous high point.
The ice core record from Greenland for its first 7-8000 years, the early Holocene, shows, virtually flat temperatures, an average drop of only ~0.007 °C per millennium, including its high point known as the “climate optimum”. But the more recent Holocene, since a “tipping point” at around 1000BC, 3000 years ago, has seen temperature fall at about 20 times that earlier rate at about 0.14 °C per millennium.
