How Activity On The Sun Could Change The Economy

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.

Solar Variability and Climate Change?

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.

The Worsening Cosmic Ray Situation

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.

Full Article is here.

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?

Scientists warn of unusually cold Sun . . .

A study by the University of California San Diego has claimed that by 2050, the Sun is expected to become cool. You might think “what’s the big deal,” but remember that this means the solar activities that create the heat of the Sun to sustain life on Earth may diminish. And the last time it happened was in the 17th century when the Thames River froze. Scientists call this the “Maunder Minimum”.

Physicist Dan Lubin at the university and his team studied the past event and concluded that we are in for a worse case. The Sun is expected to get much dimmer than last time and, in scientific terms, it is a “grand minimum” — a time period in the 11-year solar cycle when the solar activities are at the lowest point.

According to the study, titled Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short-wavelength Observation of Solar Analogs and published in the journal Astrophysical Journal Letters, this grand minimum will be 7 percent cooler than such periods from the past. [Emphasis added]

Scientists also said that the Sun might have another cooling period in a decade.

However, predicting a solar minimum or maximum is a challenge to scientists because of the non-linear characteristic of solar activities that happens every day. During a minimum cycle, though solar cycles still occur, the intensity is very low, while during a maximum cycle, solar flares go up and sun spews out billion-ton clouds of electrified gas into space. These two extremes can bring about some major global and regional climate changes.

Looks like we are going to need all the anthropogenic global warming we can generate!
