CLIMATE HISTORY AND GEOLOGY

CLIMATE HISTORY
GENERAL SITE MAP

A general guide to role of climate change in the history of the Earth. There is particular emphasis on the glaciated regions of the northern plains of North America—a region with many interesting artifacts of the Ice Ages that have been largely overlooked in the standard textbooks and reviews.
