SOLAR MINIMUM OVER THE CENTURIES
…and how it impacted the world
BOREAL MINIMUM 8350 BC-8150 BC
During this period of decreased solar activity, sea surface temperatures in the Norwegian Sea dropped by more than 2oC for around 200 years.There were also glacier re-advances in Norway and Tibet. A protective wall in Jericho, the oldest city in the world, was built at around the same time showing that change in climate also caused conflicts in human societies
SUB-ATLANTIC MINIMUM OR HOMER MINIMUM 1000 BC-950 BC
This period followed immediately after the fall of many Late Bronze Age kingdoms and the Mycenaean kingdoms in Greece. It was marked by an abrupt change from warm conditions to cold and wet conditions evident in the change in moss species and the revival of agriculture in the eastern Mediterranean region
OORT MINIMUM 1010 AD-1080 AD WOLF MINIMUM 1280 AD-1350 AD SPORER MINIMUM 1460 AD-1550 AD MAUNDER MINIMUM 1645 AD-1715 AD DALTON MINIMUM 790 AD-1830 AD
Wolf, Sporer, Maunder and Dalton solar minima coincided with an extended period of low temperatures in the medieval period known as the Little Ice Age. During this elongated period, there was a decrease in temperatures over the Mediterranean Sea, increase in sea ice in Iceland and advance of glaciers in the Alps and in Venezuela. During the Sporer minimum there was also a dry period in central Europe which was different from the previous solar minima
MODERN GRAND SOLAR MINIMUM 2020 AD-2053 AD
The impacts of the modern grand solar minimum need to be observed over the next three decades.The expectation is that global surface temperatures will go down by 10 C, which some scientists think will provide a respite from warming induced by greenhouse emissions, a projection that has been countered by many scientists, including those from NASA
