Life and climate in an ice age
What was the global impact of the growth of large ice sheets in the far north during past ice ages? What were the climates of the various continents 20,000 years ago at the height of the Last Glacial Maximum? Why was there a greater diversity of species, higher numbers of animals, more large animals, and larger animals?
