The Little Ice Age: What Happened Around the World

Between 1300 and 1850, the Earth experienced a Little Ice Age whose cause to this day is not known.

A blog post at Interesting Engineering has more details including the consequences and some paintings from the period. The causes listed are interesting:


The causes of the LIA are still not known, while potential candidates are reduced solar output, changes in atmospheric circulation, and volcanism.

Low sunspot activity is associated with lower solar output, and two periods of unusually low sunspot activity occurred during the Little Ice Age: the Spörer Minimum (1450–1540) and the Maunder Minimum (1645–1715), which is named for astronomer E.W. Maunder who discovered the absence of sunspots during that period. Both of these coincide with the coldest years of the LIA in parts of Europe.

Another possible candidate is a reversal of the North Atlantic Oscillation (NAO). This is a large-scale atmospheric-circulation pattern over the North Atlantic and adjacent areas. During its “positive” phase, the track of North Atlantic storms is centered over the British Isles and Northern Europe. During its “negative” phase, cold Arctic air from Russia moves over northern Europe.

A final candidate is volcanic eruptions which propel gases and ash into the stratosphere, where they reflect incoming sunlight. In 1783, Iceland’s Laki volcano erupted, and in 1815, the Tambora volcano on Sumbawa Island erupted.

I am voting for low sunspot activity.  Your thoughts?


Henrik Svensmark: FORCE MAJEURE The Sun’s Role in Climate Change

I am still studying this paper but wanted to share and get your feedback

Executive Summary

Over the last twenty years there has been good progress in understanding the solar influ- ence on climate. In particular, many scientific studies have shown that changes in solar activ- ity have impacted climate over the whole Holocene period (approximately the last 10,000 years). A well-known example is the existence of high solar activity during the Medieval Warm Period, around the year 1000 AD, and the subsequent low levels of solar activity during the cold period, now called The Little Ice Age (1300–1850 AD). An important scientific task has been to quantify the solar impact on climate, and it has been found that over the eleven- year solar cycle the energy that enters the Earth’s system is of the order of 1.0–1.5 W/m2. This is nearly an order of magnitude larger than what would be expected from solar irradiance alone, and suggests that solar activity is getting amplified by some atmospheric process.

Three main theories have been put forward to explain the solar–climate link, which are:
• solarultravioletchanges
• theatmospheric-electric-fieldeffectoncloudcover
• cloudchangesproducedbysolar-modulatedgalacticcosmicrays(energeticparticles originating from inter stellar space and ending in our atmosphere).

Significant efforts has gone into understanding possible mechanisms, and at the moment cosmic ray modulation of Earth’s cloud cover seems rather promising in explaining the size of solar impact. This theory suggests that solar activity has had a significant impact on climate during the Holocene period. This understanding is in contrast to the official consensus from the Intergovernmental Panel on Climate Change, where it is estimated that the change in solar radiative forcing between 1750 and 2011 was around 0.05 W/m2, a value which is en- tirely negligible relative to the effect of greenhouse gases, estimated at around 2.3 W/m2. However, the existence of an atmospheric solar-amplification mechanism would have im- plications for the estimated climate sensitivity to carbon dioxide, suggesting that it is much lower than currently thought.

In summary, the impact of solar activity on climate is much larger than the official consen- sus suggests. This is therefore an important scientific question that needs to be addressed by the scientific community.

Professor Valentina Zharkova Confirms “Super” Grand Solar Minimum [Edited}

Professor Valentina Zharkova gave a presentation of her Climate and the Solar Magnetic Field hypothesis at the Global Warming Policy Foundation in October, 2018. The information she unveiled should shake/wake you up.

Zharkova was one of the few that correctly predicted solar cycle 24 would be weaker than cycle 23 — only 2 out of 150 models predicted this.

Her models have run at a 93% accuracy and her findings suggest a Super Grand Solar Minimum is on the cards beginning 2020 and running for 350-400 years. [ Not the Grand Minimum but the full cycle ]

The last time we had a little ice age only two magnetic fields of the sun went out of phase.

This time, all four magnetic fields are going out of phase.

Here is the Professors full presentation:

I am interested in the reader view of Professor Valentina Zharkova presentation. Is it credible? Please comment, let us get a conversation going.

The Blue Sun: Solar Anomalies in the 1450s and 1460s

Willie Soon, PhD, Independent Scientist, on August 25, 2018, at the 36th annual meeting of Doctors for Disaster Preparedness Las Vegas gave a presentation on the Spore Minimum and in the presentation predicted the next Grand Minimum. Here is his graphic:

21st Century Minimum

Dr.Soon also presented some information on the connection between the sun and deep earthquakes. More deep earthquakes happen in the NH summer.

I recommend you watch the video of the presentation and then I would like to hear your comments. There is a lot to think about in the presentation.
