Fig. 10.5 Global climate
change over the past
150,000 years and
projected for the next
25,000 years. A cooling
trend is projected in the
future based on the
Milankovitch cycles, but
this may be delayed by a
warming period induced by
elevated concentrations of
carbon dioxide and other
greenhouse gases in the
atmosphere. From Mitchell
