Why be concerned about a Grand Solar Minimum?

For starters, how about starvation, plagues and collapse of empires?

Why be concerned about a Grand Solar Minimum?

J.H. Walker

Europe experienced a Grand Solar Minimum (GSM) from 585 to 620 AD.

That particular GSM was accompanied by a period of massive volcanic activity, including three widely spaced T6/T7 massive volcanic eruptions around the globe. Those eruptions masked the solar cause of the GSM. ( http://www.landscheidt.info/images/c14nujs1.jpg )

Swiss researchers documenting the GSM identified the 10-year changeover from the solar warm period benign warmth to cold, wet and very windy of the GSM.

That GSM ended the western European Roman Empire in starvation and the diseases of the Black Death.

The researchers, led by Ulf Büntgen of the Swiss Federal Research Institute, wrote an article for the journal Nature Geoscience abstract) saying the climatic changes caused “societal reorganizations” in Asia and Europe.

Their abstract states:

“We find an unprecedented, long-lasting and spatially synchronized cooling following a cluster of large volcanic eruptions in 536, 540 and 547 AD, which was probably sustained by ocean and sea-ice feedbacks, as well as a solar minimum. We thus identify the interval from 536 to about 660 AD as the Late Antique Little Ice Age. (emphasis added) Spanning most of the Northern Hemisphere, we suggest that this cold phase be considered as an additional environmental factor contributing to the establishment of the Justinian plague, transformation of the eastern Roman Empire and collapse of the Sasanian Empire, movements out of the Asian steppe and Arabian Peninsula, spread of Slavic-speaking peoples and political upheavals in China.”
