(Un) Stable Earth

The many books with ‘unstable Earth’ in their title are no doubt good at informing you how unstable Earth can be. But we are in fact living in a period of unprecedented stability of the Earth. It has not always been so.

In writing Gods, Genes and Climate I have had to learn a great deal more about the climate in prehistory. This contains a mystery that I believe is worthy of deeper exploration. So my the next book on this area will be focused on exploring an idea that might explain the mystery.

Since the younger dryas period the Earth’s climate has become much less variable than it was prior to the younger dryas. There must be a reason for this.

The thesis that (un) Stable Earth is being written to explore is whether earth crust displacement has gifted us positioning of the Earth’s landmasses that makes growth of ice-cover uniquely well balanced. We currently have the South Pole at the centre of a roughly round land-mass - Antarctica. While the North Pole is at the centre of the roughly round Arctic sea, with only the Greenland ice cap off-centre, where the weight of the ice could be exerting a gyroscopic force on the Earth’s crust.

Prior to the younger dryas, ice-cover around the North Pole would have been unbalanced, with a lot more ice one side of the North Pole compared to the other side, due to the Laurentide ice sheet. Perhaps many times in the last 100,000 years this has been the case, causing the crust to slip often. Charles Haploid felt he had evidence for at least three shifts of the poles in this period.

The book may also explore whether there are human memories of when the Earth’s climate was considerably more variable, particularly with regard to memories of the younger dryas cold period.

Do contact me if you have any thoughts about the central thesis this book will explore.
