Nice history of ice age science.  Did not read whole book, no time.

=== Chapter 12: Milankovitch Revival ===
Correlation of histories of sea level change
=== Chapter 13: Signal from the Earth ===
 . 1906 Bernard Brunhes learns bricks and then rocks freeze in Earth's magnetic field as they cool
 . 1930's? Motonori Matuyama finds reversals in lava flows in Japan and Korea
 . 1955-1965 proof of worldwide correlation
 . Vruhes-Matuyama boundary 700 kya, later found in deep-sea cores
=== Chapter 14: Pulsebeat of Climate ===
 . ice sheets large, central Europe polar climate, windy with loess deposits.  
  . ice sheets small, warm and wet with broadleaf trees
 . oxygen-isotope ratio varies from 0 to -2 (something), 6 times in 400 Ky
=== Ch 15: Pacemaker of the Ice Ages ===
 . 1971 CLIMAP project
  . International Decade of Ocean Exploration IDOE.  Columbia, Brown, OSU;  later Maine and Princeton, later worldwide
=== Ch 16: The Coming Ice Age ===
 . Photocopy on file 
 . Fig 43 shows temperature variation over last 11 ky, with a climatic peak ("optimum") at 6.5 kya, and a 6C colder minimum at 10.5 kya.   The "little ice age" is shown.  No citation for the data source, it may be illustrative rather than a direct plotting of data.
 . Fig 45 is the last 1000 years, with the "little ice age" featured, adapted from [[ http://www.nature.com/nature/journal/v223/n5212/pdf/2231209a0.pdf | H.H. Lamb 1969 ]]
