I wrote last week about the coming Grand Solar Minimum, something that will have much more impact on the environment than anything we puny humans can do. It generated a lot of interest from all sides, so it’s time to delve deeper into what we can expect.
Starting with the hype: During the last grand solar minimum (GSM), the Maunder Minimum of 1645 to 1715, glaciers advanced, rivers froze, sea ice expanded — in short, the Little Ice Age. Is another one is almost upon us?
TRUTH LIVES on at https://sgtreport.tv/
Probably not. Maunder occurred at the tail end of a bi-millennial cycle. These cycles range between 2,000 and 2,600 years in length and see the Earth first warm, then cool. Gradual cooling had been going on for hundreds of years. Maunder just capped it off. Today we are a few hundred years into the warming phase of the subsequent bi-millennial cycle. Different starting conditions yield different paths.
The progressives say that we’re so deep into anthropogenically accelerated climate change (AACC) that there’s almost no time left to turn things around. If we don’t act now, it will be too late.
Nope, sorry squad members. What we can predict, instead, is an overall temperature reduction of 1 degree Centigrade by the end of the GSM. Afterward, natural warming at the rate of around 0.5 C. every hundred years will continue for the next 600 years or so.
That gives us a good 35 to 50 years to hone the science and come up with the best ways to mitigate the impact of unstoppable global warming on humankind; until, that is, it naturally reverses. See suggestions below for better uses of funding currently earmarked to address the “climate crisis.”
Reasonably speaking: We’ve been warming, so the cooling of the GSM will just even us out for a while. Therefore, nothing to worry about, right?
Well, not quite. There are a few worries. Plants grow in response to warmth, moisture, nutrients, and most importantly sunlight. Even if the temperature does not plunge to glacial depths, some cooling will take place and clouds are expected to grow denser and cover much of the earth’s surface as this GSM bottoms out. If normally-correlating volcanism takes place, the additional material in the atmosphere will further darken the globe and provide even more opportunity for condensation and cloud formation.
Last year, Dr. Valentina Zharkova wrote “This global cooling during the upcoming grand solar minimum…would require inter-government efforts to tackle problems with heat and food supplies for the whole population of the Earth” (not to mention their livestock).
The pessimists ask, what else can go wrong? Well, cooling will increase the demand for heat, darker days will increase the demand for light, and unfavorable outside conditions will increase the demand for power for enclosed food production. With more power needed, the amount we currently rely on from solar installations will decrease as cloud cover limits their efficacy.
A decrease in solar ultraviolet radiation can be expected to slow the formation of ozone in the atmosphere, a lack of which tends to destabilize the jet stream, causing wilder weather. Wind generators turn off when the wind is excessively strong. As we now know, they are not immune from freezing in place. In the face of a greater demand for power, we will generate less.
Even worse is this: Historically, GSMs have been associated with extreme weather events. Floods, droughts, heavy snowfall, late springs, and early autumns have all resulted in famine. Famine during GSMs has led to starvation and societal upheaval. No one wants the former, and I think we’ve seen enough of the latter this past year or so to do for our lifetimes.
We’re about 16 months into this GSM, with 32 more years to go. Already 2019 and 2020 saw record low numbers of sunspots. We’ve had lower than expected crop harvests due to unseasonable rains both years. The April 2021 USDA World Agricultural Product report has articles detailing Taiwan’s expected 20% decrease in rice production this year over last, Cuba’s rice production 15% below its five-year average, Argentina’s corn, Australia’s cotton, Malaysia’s palm oil — all down, all due primarily to the weather. There are some expected bumper crops, all based on expanded acreage.
