Sustainable Development 3 - Grand Solar Minimum

Ice Ages start after Climate Optima at the Poles - The Holocene Climate Optimum was reached 10,500 years ago in Antarctica (EPICA Dome-C), 8,000 years ago in Greenland, and 2,100 years ago globally. Therefore, the Ice Age started 8,000 and 10,500 years ago in the north and south poles respectively, and 2,100 years ago globally. The interval between the Holocene Climate Optimum (Global & Dome-C) and its preceding climate optimum was the longest of all previous glacial cycles. How do you statistically justify delaying the ice age by 30,000 years?

Earth entered a new ice age after the Holocene Climate Optimum

Nine of Antarctica EPICA Dome C’s glacial cycle temperature peaks (climate optima) were compared with their corresponding global climate optima

The Last Ice Age Ended 20,000–24,000 Years Ago, Not 11,700 Years Ago

Reconstructed global, Antarctic, and Arctic glacial cycle temperatures from the last glacial maximum or end of the last ice age

A new ice age was entered after the Arctic Holocene Climate Optimum

The Arctic entered the new ice age after the Holocene Climate Optimum 8,000 years ago. Between 6000 BCE and 1700

Glacier ice build up peaked during the Little Ice Age

Arctic and Antarctic glacier ice build up began about 5,000 years ago after the Holocene Climate Optimum. Significant glacier advances

Abrupt global cooling happens after extreme global warming phases

The conclusion I drew from this analysis was two-fold. Firstly, there is a greater probability the climate will switch back

A glacial cycle is comprised of sequential freeze-thaw phases

During the last 1 million years the average glacial cycle has lasted for 92,900 years, the average interglacial period was

Solar activity controls the climate system, and global warming started in 1700

Solar activity (magnetism) controls centennial-scale climate change, not carbon dioxide. Global warming started in 1700 before significant human activity. The

Cold climates follow a grand solar minimum of solar activity (magnetism)

A cold climate was experienced in the Northern Hemisphere during the grand solar minima of the Little Ice Age. The
