Not quite what I was expecting but still a very good read
on 26 July 2017
This is an excellent little book. I was surprised to find the first 60% devoted to describing the lamentably slow evolution of man's acceptance and understanding of the glaciation/de-glaciation process. We then get an explanation of the small but crucial nudges applied by astronomical effects before gaining a clear understanding of deep ocean sediments, oxygen isotope analysis and other increasingly sophisticated dating methods. Finally we reach the development of ice core analysis in the last 50 years that has provided the most detailed granularity of understanding. This is predominately a history book about geological detective work. It is not the textbook in glacial landforms that I half-expected, but it is well written and I am glad to have read it.
