[* Not continuous days, an accumulation of blank sunspot days ]
2 July 2018 – “The Belgian department of solar physics research (SIDC) says we are about to touch 100; that is, a hundred days in which we do not see spots on our sun,” says Italian meteorologist Dr Carlo Testa.
During a time of few or no sunspots (a solar minimum) the Sun emits less energy than usual, says Dr Testa. “According to some scholars this situation could lead to climatic upheavals.”
Suffice it to recall, says Testa, that between 1645 and 1715 the most significant solar minimum of history, the Little Ice Age, occurred, bringing years and years marked by very strict winters that lasted until June.
Now several studies indicate that we’re headed into another Great Solar Minimum, says Testa. For some scholars this is only a hypothesis, but we are seeing small signals that support this idea: namely,the most powerful strat-warming ever recorded in mid-February, the very very unstable Spring, and finally this summer that continues to limp along.
In the immediate future Testa expects “a very limp and less hot summer than in past years,” and that the coming winter could also be affected by the solar minimum.
“What if the worst is to come?” asks Testa.

Hailed as ‘the last piece of the puzzle’ in codifying our understanding of the mechanism(s) that cause climate changes, scientists are increasingly turning to Sun-modulated cosmic ray flux and cloud cover variations as the explanation for decadal- and centennial-scale global warming and cooling. In other words, climate changes are increasingly being attributed to natural variability, not anthropogenic activity.

26 Apr 2018 – “Worldwide Wine Output Collapses To 60-Year Low, Sparks Fears Of Major Shortage,” says zerohedge.com headline.
The Director-General of the International Organization of Vine and Wine, Jean-Marie Aurand, warned that global wine production collapsed in 2017, with a contraction of 8.6 percent compared with 2016. In fact, global wine output dropped to its lowest levels since 1957, primarily due to poor weather in the Eurozone which slashed production across the entire bloc.
In France, vinters reported “widespread damage in Bordeaux, Burgundy, and Champagne, with some losing their entire 2017 crop.

All indications are that the upcoming solar minimum which is expected to begin in 2019 may be even quieter than the last one which was the deepest in nearly a century. One of the natural impacts of decreasing solar activity is the weakening of the ambient solar wind and its magnetic field which, in turn, allows more and more cosmic rays to penetrate the solar system. The intensification of cosmic rays can have important consequences on such things as Earth’s cloud cover and climate, the safety of our astronauts exploring in space, and lightning.

The thin blue line indicates the daily sunspot number, while the dark blue line indicates the running annual average. The recent low sunspot activity is clearly reflected in the recent low values for the total solar irradiance. Data source: WDC-SILSO, Royal Observatory of Belgium, Brussels.

Approaching ‘grand solar minimum’ could cause global cooling
Forbes: Simon Constable reviews Nature’s Third Cycle: A Story of Sunspots by Arnab Rai Choudhuri.
But what has become more apparent based on more recent research from NASA is that we are now in a period of very few or no sunspots. This has coincided with the brutal winter we are going through now.
The question is whether we will enter another grand solar minimum just like the Maunder minimum which if history is a guide would mean a period of much colder weather winters and summers. More than a few experts with whom I speak regularly believe that we shall enter such a grand minimum along with the resulting bone-chilling weather.
If that happens, then there will be profound influences on the economy, including possible crop failures and rising energy use for home and workplace heating. Or in other words, expect bigger bills for food and energy. After a period in which the supply of both has been increasingly abundant then this change will likely come as a shock to many people and likely the broader global economy as well.

Why has global temperature been increasing since 1980 while solar activity has been decreasing?
A paper by Javier, edited by Andy May at WUWT.
The answer is that solar variability has multiple effects on climate with different time lags. Total Solar Irradiation variability has a direct effect on temperature within 0-2 years of ~ 0.2 °C (Tung & Camp, 2008) for the 11-year solar cycle. This is the effect accepted by all. The stratospheric effect of UV solar variability influences the North Atlantic oscillation that is lagged by 2-4 years (Scaife et al., 2013). Kobashi et al. 2015 describe a 10-40-year lag on Greenland temperature from ice cores that they attribute to the slowdown of the Atlantic Meridional Overturning Circulation and correlates with changes in the wind stress curl in the North Atlantic with a lag of 38 years in solar variability. Several studies correlating changes in tree-ring width and solar variability document a 10-20-year lag (Eichler et al., 2009; Breitenmoser et al., 2012; Anchukaitis et al., 2017).
The existence of multiple lags means that for the full effect of solar variability to be felt on climate there is a delay of ~ 20 years. The delay is due to the recruitment of slower changing atmospheric and oceanic climatic responses.
This means two things:
- Changes over the 11-year cycle are too fast to have much impact on climate.
- The general decline in solar activity since 1980 has been felt on climate from ~ 2000, and the low solar activity of SC24 should have a maximum effect on climate ~ 2035.
The evidence suggests that solar variability strongly influences climate change. The solar-hypothesis makes very clear predictions that are the opposite of predictions from the CO2-hypothesis. Regardless of changes in CO2 levels and emissions, the world should not experience significant warming for the period 2000-2035, and might even experience some cooling. If the prediction is correct we can assume that the solar contribution to climate is stronger than the CO2 contribution. Then more warming should take place afterwards.

Cosmic rays are bad–and they’re getting worse. That’s the conclusion of a new paper just published in the research journal Space Weather. The authors, led by Prof. Nathan Schwadron of the University of New Hampshire, show that radiation from deep space is dangerous and intensifying faster than previously predicted.

How does this affect us? Cosmic rays penetrate commercial airlines, dosing passengers and flight crews so much that pilots are classified by the International Commission on Radiological Protection as occupational radiation workers. Some research shows that cosmic rays can seed clouds and trigger lightning, potentially altering weather and climate. Furthermore, there are studies […] linking cosmic rays with cardiac arrhythmias in the general population.
Cosmic rays will intensify even more in the years ahead as the sun plunges toward what may be the deepest Solar Minimum in more than a century. Stay tuned for updates.
If cosmic rays increase cloud cover, this could be how the cooling takes place during grand minimums. We are going to have an opportunity to observe one. Your thoughts?
