Ice Ages


(Concerning Ice Ages) “As usual JJ does not have correct scientific facts.”


I am pretty careful about my scientific facts, thank you. It is rare that someone makes a legitimate correction of what I write.

There are numerous cycles that are called ice ages. The greater ice age, the Pliocene-Quaternary glaciation, started about 2.58 million years ago. Within that cycle have been lesser ice ages said to range from 40,000 to 100,000 years. Within that cycle are lesser ones still ranging from 10,000 to 12,000 years and within that cycle are 1,500 year cycles. This last 1,500 year cycle was called “The Little Ice Age” that ended with the recent warming which began around 1850.

A good case for the 11,500 year cycles was made by Robert Felix in his book Not by Fire But by Ice. He makes a good case for the fact that the 11,500 year cycles have occurred regularly for millions of years.

A case for the 1500 year cycles was made by S. Fred Singer and Dennis T. Avery in their book Unstoppable Global Warming: Every 1,500 Years – a very well written book I might add.

Dates of previous cycles are regularly disputed and revised so there is no way of knowing who is making the most correct estimates.
