Editor’s Note: The Russian study was originally published July 2015 and was reported on earlier on this blog. Lawrence provides some additional supporting evidence.
Lawrence Solomon writing in the Financial Post:
“The New Little Ice Age Has Started.” This is the unambiguous title of a new study from one of the world’s most prestigious scientific institutions, the Russian Academy of Science’s Pulkovo Observatory in St. Petersburg. “The average temperature around the globe will fall by about 1.5 C when we enter the deep cooling phase of the Little Ice Age, expected in the year 2060,” the study states. “The cooling phase will last for about 45-65 years, for four to six 11-year cycles of the Sun, after which on the Earth, at the beginning of the 22nd century, will begin the new, next quasi-bicentennial cycle of warming.”
Abdussamatov was once a lonely voice in the view that Earth could be embarking on a prolonged cooling spell due to solar, not manmade, factors. No longer. Because sunspots are eerily disappearing from the face of our sun — just as they disappeared during the Little Ice Age in the late 1600s — speculation of another cooling period has been widespread by bodies such as the National Astronomical Observatory of Japan and the Riken research foundation. Last year, a team of European researchers unveiled a scientific model at the National Astronomy Meeting in Wales predicting a “mini ice age” from 2030 to 2040 as a result of decreased solar activity.

A monthly smoothed maximum sunspot number of 62 is derived for Solar Cycle 25. This would probably be around 2025. This is almost down to Dalton Minimum levels.

My prediction for the peak sunspot number of Cycle 25 is a monthly count of 62.

David mentions the Dalton Minimum. Cycle six was a companion cycle during the Dalton Minimum. If David’s prediction is accurate, Cycle 25 will be much like Solar Cycle 6, which could bring on more Dalton like climate variation.
The climate was cooler during the Dalton Minimum. Cycle 24 so far has produced the 18-year global warming pause. The IPCC credits the “hiatus” partly to decreased solar activity. Cycle 25 will most likely continue this cooling evident in Cycle 24.
Dalton Minimum resulted in an average temperature drop of about 1 Degree C. This resulted in shorter growing seasons, with later spring frosts and early rain and snow in the fall. Some of which was caused by the eruption of Mount Tambora in Indonesia in 1816, one of the two largest eruptions in the past 2000 years. This mix of low sunspots and volcanic activity makes a climate prediction for more difficult. However there some speculation that reduced solar activity on the sun results in more volcanic activity on this planet. Increase vulcanization produces cooler climates. Stay tuned, this is going be an interesting time to be climate observers.

The evidence for a persistent irregular climate cycle with a period of 2400 ±200 years is strong. There is compelling evidence of a solar cycle of about the same length and phase; suggesting that the solar cycle might be causing the climate cycle. We will present a summary of the evidence, beginning with the original paleontological evidence, followed by the cosmogenic radionuclide (10Be or Beryllium-10 and 14C or Carbon-14) evidence. For more information, a bibliography of many papers discussing topics relevant to the Bray (Hallstatt) cycle can be found here. Only a small portion of the relevant papers are mentioned in this summary post.
This is the section that mentions solar grand minimums and maximums
The Bray cycle appears to be closely tied to tight clusters of grand solar maxima and minima. The Little Ice Age Wolf, Spörer, Maunder and Dalton grand minima are the best example of a solar grand minima cluster and they fall in a Bray low. The Greek Dark Age and the Homer grand minimum also fall in a Bray low. Significant historical events that fall in Bray lows are labeled in figure 2. A more complete picture of these events can be found here. The Little Ice Age (LIA) is a well-known cold period filled with plagues and suffering due to cold, for more details see here and in Dr. Wolfgang Behringer’s excellent book. The period labelled “GDA” is the Greek Dark Ages, during this Bray low the Late Bronze Age ended and after a period of civilization collapse, the Early Iron Age started. The “Uruk” Bray low event corresponds with the expansion of the Uruk civilization and the growth of some of the world’s first cities. Near the end of the Uruk Bray low, the Middle East transitions from the Copper Age to the Early Bronze Age and cuneiform writing appears.
You can read the full text of this interesting essay HERE. I also found the comments on this essay by Andy May and Javier very interest and worth your time to review. It is clear we have multiple solar cycles creating a complex mix of overlapping cycles, where the sum of the influence waxes and wains over time. We live in a complex universe.
These Russian findings have been reported on before, however it is interesting to follow this link to some really cool graphics of a cooling earth.
Meteorologist Paul Dorian writes about a Spaceweather.com Study, which was reported on here in January 2016.
Current cosmic ray activity
We happen to be in a weak solar cycle (24) which is actually on pace to be the weakest cycle in more than one hundred years. Therefore, it would not be surprising to have relatively high cosmic ray penetration into the Earth’s atmosphere; especially, since we are now heading towards the next solar minimum phase when solar activity is generally even quieter. During solar maximum, CMEs are abundant and cosmic rays are held at bay.
In fact, for the past year, neutron monitors around the Arctic Circle have sensed an increasing intensity of cosmic rays. Polar latitudes are a good place to make such measurements, because Earth’s magnetic field funnels and concentrates cosmic radiation there. As it turns out, Earth’s poles aren’t the only place cosmic rays are intensifying. “Spaceweather.com” has led an effort in the launching of helium balloons to the stratosphere to measure radiation, and they find the same trend increasing intensity of cosmic rays over California. Their latest data show an increase of almost 13% since 2015. [For more on this study click here]:
Cosmic rays have been steadily increasing in recent months during historically weak solar cycle 24; plot courtesy spaceweather.com and California data courtesy study sponsored by spaceweather.com
In the plot, neutron monitor measurements from the University of Oulu Cosmic Ray Station are traced in red; gamma-ray/X-ray measurements over California are denoted in gray. The agreement between the two curves is remarkable. It means that the intensification of cosmic rays is making itself felt not only over the poles, but also over lower latitudes where Earth’s magnetic field provides a greater degree of protection against deep space radiation. There’s a new section on spaceweather.com where you can monitor cosmic rays in the atmosphere.
As reported elsewhere on this blog, here, more cosmic ray has been shown to produce more clouds, and more clouds reduce the plant’s temperature. We can expect some cooler climate as Solar Cycle 24 sunspots and CMEs decline.
Dr. Sten Odenwald, a retired astronomer and educator formerly with the National Institute of Aerospace and NASA writing in the Huffington Post. He concludes his sunspot article, Waiting For The Next Sunspot Cycle 2019-2030, with this view forward:
Statistically speaking, the current Cycle 24 is scheduled to draw to a close about 11 years after the previous sunspot minimum in January 2008, which means sometime in 2019. We entered the Cycle 24 sunspot minimum period in 2016 because in February and June, we already had two spot-free days. As the number of spot-free days continues to increase in 2017-2018, we will start seeing the new sunspots of Cycle 25 appear sometime in late-2019. Sunspot maximum is likely to occur in 2024, with most forecasts predicting about half as many sunspots as in Cycle 24.
The bad news is that some studies show sunspot magnetic field strengths have been declining since 2000 and are already close to the minimum needed to sustain sunspots on the solar surface. This is also supported by independent work in 2015 published in the journal Nature. By Cycle 25 or 26, magnetic fields may be too weak to punch through the solar surface and form recognizable sunspots at all, spelling the end of the sunspot cycle phenomenon, and the start of another Maunder Minimum cooling period perhaps lasting until 2100.
But the good news seems to be that none of the current forecasts suggest Cycle 25 will be entirely absent. A few forecasts even hold out some hope that a sunspot maximum equal to or greater than Cycle 24 is possible.
