Planetary science: Icy martian mysteries
Victor R. Baker1
Abstract
Both Mars and Earth have experienced ice ages in geologically recent times. Coincidence of the phenomenon on two planets will further the scientific quest to answer the question of how ice ages originate.
Among the grandest of mysteries about planet Earth is the origin of its ice ages and related climate change. Human civilization developed during a warm, 'greenhouse' climatic interlude of several thousand years within the overall 'ice-house' conditions of a major ice age that became most intense during the past two million years.
