Professor Albert Zijlstra: The History of the Earth

Our guest speaker on 22-Feb-2017 was professor Albert Zijlstra, of The University of Manchester, who delivered an excellent talk on The History of the Earth.  Professor Zijlstra has kindly provided links to two web sites (blogs) on which he discusses some related topics:

Ice ages:
Calanais   (actually the history of Scotland)

Professor Zijlstra managed to compress the entire history of the earth (about 4.5 thousand million years) into about one and a half hours - a compression ratio of about 25,000,000,000,000 to 1;  you will understand, therefore, that the web sites contain a considerable amount of information that is well worth exploring.
